The Tools for Asbestos Abatement

The Tools for Asbestos Abatement

With federal and state laws in place, the use of asbestos in products and materials is restricted in the United States, but not banned. Canada, however, has regulations in place that prohibit the import, sale, and use of asbestos and products containing the dangerous carcinogen. However, this wasn’t always the case. Prior to its close in 1990, much of the world’s supply of vermiculite came from a mine in Montana. Unfortunately, the mine also contained a natural deposit of asbestos, which contaminated the vermiculite product. Materials like drywall, flooring, ceilings, cement, and insulation were produced using vermiculite from the mine, which was primarily sold as insulation in Canada under the trademarked name “zonolite.”

The risks of asbestos

But, what’s the risk of vermiculite containing asbestos? The inhalation of asbestos has been proven to cause lung cancer and other severe respiratory diseases. Because of this risk, the removal or disturbance of asbestos should be performed with the proper precautions and equipment. Proper sampling, testing, and removal procedures are essential to identify and safely mitigate the hazard associated with asbestos in buildings.

Experts and their techniques for asbestos removal

Asbestos testing requires expertise. This is not a DIY project. Professionals will come prepared with an air purifying respirator equipped with HEPA-filtered cartridges to wear during sampling, along with safety glasses. A respirator is recommended by both the U.S. EPA and Health Canada as best practice to reduce the amount of dust inhaled during collection.

Once asbestos has been tested and identified in a material, it’s important to begin the abatement process. The Ontario Regulation for Designated Substances (Reg. 278/05) classifies asbestos removal based on the severity of the risk - Type 1 (Low Risk), Type 2 (Medium Risk), and Type 3 (High Risk). When the risk is low, the size of the contaminated area is between 1 and 10 sq ft, and the material is non-friable asbestos-containing material (ACM), meaning it is being held together by a bonding agent. In a Type 2 abatement, the contaminated area is between 11 and 100 sq ft, and is friable ACM, meaning it is easily crumbled and breaks apart with touch. A Type 3 abatement operation means the contained area is over 100 sq ft and contains both friable and non-friable ACM. A Type 3 operation, involves the removal or disturbance of more than one square meter of friable ACM during the repair, alternation, maintenance or demolition of a building.

Tools of the trade

Type 2 and Type 3 abatement require professionals to wear the proper respirator as well as PPE equipment like disposable coveralls to prevent entry of dust. A trained professional will not only know the measures to protect themselves, but others around them. These measures include the isolation of the entire area using temporary containment barriers like Abatement Technologies SHIELD WALL™.

Additionally, during these types of abatement, it's important to use a HEPA filtered vacuum extraction system, like our HEPA vacuums to clean up asbestos dust throughout the project, avoiding particulates and carcinogens being left behind after a project. A vacuum extraction system offers the benefit of adding an engineering control of increased negative draw of air at the point of disturbance. This decreases the exposure to the worker as opposed to other methods which may increase the airborne concentration within the asbestos work area.

The Basics of Respirator Fit Testing

In this blog, we break down when you should fit test respirators, the difference between qualitative and quantitative fit testing, as well as how to choose which test is right for your respirator.

No matter how advanced a face respirator is, if it doesn’t fit right, it won’t protect the wearer. That’s why fit testing is essential.

In the US, the Occupational Safety and Health Administration (OSHA) requires fit testing before using a mandatory respirator for the first time and annually after that. The rules are similar in Canada. According to the Canadian Standards Association (CSA) and Ontario’s Occupational Health and Safety Act (OHSA), workers whose jobs require them to wear a respirator must complete fit testing before their first use.

Additionally, they must complete a fit test:

- At least every two years, according to the CSA (Z94.9.1.6)

- After significant weight gain or loss, surgery, major dental work, or other physical changes that could affect a respirator’s fit

- When changing to a new respirator make or model

Qualitative vs. Quantitative fit testing

There are two types of fit testing: qualitative and quantitative. Qualitative fit testing is a subjective test that relies on the wearer's sense of taste or smell to determine if the respirator fits properly. This type of testing is a simple pass-or-fail method that does not measure the extent of leakage. OSHA accepts four methods for qualitative fit testing: isoamyl acetate (banana oil test), saccharin, Bitrex, and irritant smoke.

Quantitative fit testing, on the other hand, is a more objective and precise method of testing the fit of a respirator. This type of testing uses specialized equipment to measure the amount of leakage around the respirator's seal. Quantitative fit testing requires a controlled environment and trained personnel to administer the test. The three OSHA-accepted methods for quantitative fit testing are generated aerosol, ambient aerosol, and controlled negative pressure.

Should you use qualitative or quantitative fit testing?

Wondering which method of fit testing is best? The quick answer is: it depends.

Qualitative fit testing may be used for negative pressure respirators, such as N95 masks if they are being used in environments less than 10 times the permissible exposure limit (PEL). If contractors are using negative pressure respirators in environments above 10 times the PEL, they must use qualitative fit testing.

For positive pressure respirators, either qualitative or quantitative testing will work. That is because positive pressure respirators supply their own air, and thus can overcome minor leaks.

How to conduct qualitative fit testing

To perform qualitative fit testing, the wearer must put the respirator on and adjust it to fit their face. The test administrator will then instruct the wearer to perform a series of exercises, such as talking, nodding, and moving their head from side to side, simulating normal workplace movements.

During the test, the administrator will introduce an irritant to the environment, such as banana oil, Bitrex, saccharin, or smoke, and ask the wearer to indicate if they can taste or smell the test agent. The test administrator will also visually inspect the respirator for any leaks or gaps. If the wearer can taste or smell the test agent, or if there are visible leaks, the respirator does not fit properly and should be adjusted or replaced.

Qualitative fit testing is a simple and cost-effective way to determine if a respirator fits properly. However, it is not as precise as quantitative fit testing is more precise and may not detect all leaks or fit issues.

How to perform quantitative fit testing

To perform quantitative fit testing, the wearer must properly put on the respirator and adjust it to fit their face. The test administrator will then use specialized equipment to measure leakage around the respirator's seal.

The equipment used for quantitative fit testing typically includes a probe placed against the wearer's face near the respirator's seal. The probe is attached to a special filter adapter, which then passes through the respirator to sample the air inside of the mask... As in qualitative testing, the wearer will be instructed to perform a series of exercises, such as talking, nodding, and moving their head from side to side to simulate workplace movements.

The test results are then compared to the manufacturer's fit factor, which measures the respirator's effectiveness. If the fit factor is within the acceptable range, the respirator fits properly. If the fit factor is outside of the acceptable range, the respirator does not fit properly and should be adjusted or replaced.

Quantitative fit testing is a more precise and accurate method of testing the fit of a respirator. However, it requires specialized equipment and trained personnel to administer the test. It is recommended that quantitative fit testing be performed whenever a new respirator is used, or when there are changes to the wearer's facial structure.

Get the most out of your respirator

Whether it’s qualitative or quantitative fit testing that you need, be sure to stay up to date with fit testing requirements for your respirator. Doing so not only ensures compliance but will help you stay safe amid a variety of work environments.

Winter Maintenance Guide: Frozen pipes

A Winter Maintenance Guide to Preventing Frozen Pipes

As the weather gets more frigid with each passing day in many parts of the world, it's important to be prepared for freezing temperatures. Frozen pipes are notoriously known to cause a significant amount of damage every year, and can result in thousands of dollars in damages if not handled correctly. When water freezes and expands, pressure builds, and vulnerable pipes are likely to burst. The smallest crack in a pipe can spew hundreds of gallons of water, resulting in flooding, mold, and structural damage. Unlike winter storms, bursting pipes are largely preventable with the right preparation. Here are a few tips on how to prevent frozen pipes, how to thaw frozen pipes before they burst, and how to avoid water damage before it’s too late:

Preventing Frozen Pipes

When temperatures drop below -6° C for at least six consecutive hours, pipes are at a risk of freezing. In order to mitigate the risk, it’s crucial to consider the following:

Insulate pipes: Pipes that are exposed, pipes that run through exterior walls, and pipes that are located in unheated crawl spaces, attics, and basements are all highly susceptible to freezing. To build thermal protection around pipes, it’s important to use materials like tubular foam, pipe wrap, and heat cable to raise water temperatures by -15.56° C.

Seal leaks: Air leaks around electrical wiring and vents allow frigid temperatures to make their way around vulnerable pipes. Look for cracks around the building and tightly seal with caulk, weatherstripping, or additional insulation materials to keep cold air outside.

Keep consistent temperatures: Thermostats should be kept at a consistent temperature throughout the day and night. Dropping the temperature indoors at night may offer a lower heating bill, but adjusting below 12.78° C during extreme cold can cause a devastating strain on both pipes and furnaces.

Thawing Frozen Pipes

If only a few drops of water trickle out of a faucet when it’s freezing outside, there’s a good chance the pipes are frozen. In this stage, it’s not too late to take action before they burst:

Apply heat: Slowly apply heat using an electrical heating pad, a space heater, or hot towels. Be cautious of using appliances in areas of standing water to avoid electrocution. Start by warming the pipe as close to the faucet as possible, gradually moving towards the coldest portion of the pipe.

Keep water running: While treating the pipes, keep faucets turned on to allow a consistent flow of water. As the frozen area begins to melt, running water will assist in preventing pressure buildup and blockages that can cause a burst.

Check all faucets: If one pipe is frozen, it’s likely not an isolated situation. Check all faucets around the building for dripping water and repeat the heating process until all water pressure is restored.

After Pipes Burst

When frozen pipes go undetected and untreated, ice blockages will likely cause pipes to burst. After the burst occurs, it’s critical to take immediate action.

Contact a water restoration expert: When it comes to mold and bacteria, time is the enemy. Everything that comes into contact with water must be properly dried, cleaned and disinfected within 48 hours to avoid residual damage. Trained professionals know the quickest, safest, most efficient ways to salvage the building and its contents by measuring and recording temperature, moisture, and humidity.

Shut off water: Locate the main water supply and shut it off to stop the heavy flow of water. Leave faucets on to relieve the pipe of remaining pressure and cold water. If the leak occurred near any electrical sockets or fuse boxes, it’s crucial to turn electricity off.

Remove standing water: The longer water stays in the building, the higher potential for mold and mildew issues. Remove as much water and moisture from the area as possible, while waiting for the experts, using a durable dehumidifier and high-speed air mover. Carpeting, drywall, rugs, cloth, and other porous materials are the most vulnerable to damage.

But if disaster does strike, check out our blog on Disaster Restoration Solutions.

Winterization checklist: How to prepare your building for winter

Winterization checklist: How to prepare your building for winter

Avoid property damage with these quick tips

Winters in Canada and the northern U.S. are notoriously harsh. Each year, piled-up snow and ice damages roofs, and frozen pipes burst to wreak havoc on structures of all shapes and sizes. While winter storms are outside your control, preparing for them is not.

Here are some quick tips to prepare your building for winter.

Prevent Plumbing and Pipe Problems

One of the main threats that cold weather poses to buildings is frozen pipes. When pipes freeze, they burst, and the ensuing water damage can lead to mold growth, structural damage, and significant repair costs. Here’s what you can do to prepare:

Keep inside temperature above 55F/12C to prevent freezing
Check pipes for any air leaks
If pipes are in non-insulated or non-heated areas, consider wrapping pipes in insulation to prevent freezing

Additionally, it’s best to expect the unexpected and prepare for the worst. In this case, that means having equipment on hand to handle flooding. When a pipe bursts and water spills into your building, the clock immediately begins ticking. Mold can form in just 24-72 hours. If you don’t have equipment on hand, you’ll be asking how to get rid of mold rather than how to prevent it.

Here are some items you’ll want to have around in the case of a burst pipe:

Air movers, such as the RAPTOR® RAM1000 Centrifugal Air Mover
Dehumidifiers, such as the AQUATRAP® AT150RS LGR Dehumidifier

When flooding occurs, use air movers to dry the building and dehumidifiers to capture and remove the moisture in the air.

Secure your Structure

Though snow may look light and fluffy when it’s falling, anyone who has shoveled snow knows that fluffy snowflakes accumulate into dense snow packs. While snow piling on your driveway may be little more than an annual inconvenience, snow piling on roofs can cause severe structural damage.

The most dramatic example of structural damage from snow is roofs caving in. But this isn’t the only, or the most common, way that snow and ice on roofs can cause damage. The more common threat to structures from snow buildup is water damage. Snowmelt on roofs can leak into attics and cause mold growth. This can happen when shingles are missing or broken on the roofs, allowing water to seep through.

Additionally, ice dams forming around gutters are a major concern. Like caved-in roofs, falling icicles causing serious injury or death to passersby are a dramatic example. More commonly, these icicles grow in size and weight, putting strain on gutters and causing them to break. When this happens, the falling gutters and ice can damage the rest of your structure and make exposed portions of the structure liable to water damage.

Here’s what you can do to protect your roof from snow and ice:

Clean the gutters, removing any leaves, debris, snow, or ice
Inspect the roof, looking for missing or broken shingles
Install heated cabling to warm your roof and prevent snow buildup

Have your HVAC’s Back

Your HVAC system has your back all year, keeping you cool in the summer and cozy in the winter. The least you can do is ensure it’s set up for success going into winter. As you put more strain on your HVAC system to heat your building throughout the cold winter months, here are a few things you can do to have its back:

Change the filters
Empty condensation traps
Inspect the system for any blockages

Win with Winterization

At times, winter can feel like a primal battle between you and the elements. You never know what winter will throw at you, but by preparing for the worst, you set yourself up for success no matter what winter holds. This winter, be ready for anything with Abatement Technologies equipment at your disposal and win the battle against winter.

What to do When Flooding Occurs in a Hospital

What to do When Flooding Occurs in a Hospital

Hospitals, like all buildings, are subject to maintenance, repair, and restoration needs, sometimes at a moment's notice. Few building emergencies are worse than flooding. Whether it’s natural disasters flooding from heavy rain and hurricanes, or floods from equipment failure like burst pipes, floods are an emergency that can keep building managers up at night. This is perhaps more so in hospitals where increased regulations and patient safety concerns are cause for special precautions.

Protecting Patients

When flooding occurs in a hospital and remediation is required, the number one priority is to protect patients throughout the process. After all, patients come to hospitals to be cured, not put in harm's way. In the case of hospital construction, maintenance, or restoration, one of the first steps is to construct containment walls around the affected area. Like isolating a patient, construction areas need isolation, too. With flooding, contractors need to contain the affected area to stop the spread of mold into adjacent spaces. In many cases, poly sheeting will be used to create a containment space. In high risk environments and larger disaster areas, drywall may be required.

Once the containment is in place contractors create a negative pressure environment using HEPA-filtered negative air machines or portable air scrubbers. Creating a negative pressure environment helps ensure that unfiltered air inside the containment area does not leak out. The HEPA-filtered negative air machines and portable air scrubbers draw contaminated air in, filter the air, and then exhaust the filtered air out of the containment area through ductwork. Federal, state, provincial, local, and facility regulations will determine whether HEPA air can be discharged inside or whether it needs to be directed outside.

Acting Fast

In cases of flooding, acting fast is imperative. Mold grows in 24-72 hours, and the longer a building stays wet, the longer mold has to grow. Once mold grows, it becomes much more difficult to get rid of and can be a health risk. Therefore, remediation teams must act fast. However, constructing traditional walls can take days. That’s where the SHIELD WALL® comes in. Unlike traditional walls, these lightweight polycarbonate walls are easy to transport and can be set up by a small team in a matter of hours, not days, allowing remediation teams to quickly get to work.

Reducing Waste

In an emergency, it’s a natural human instinct to get the job done as quickly as possible. One might choose to use whatever materials are readily available, which might not be the most financially conscious or sustainable route. Using single-use solutions only adds more to the financial burden. When hospitals construct temporary drywall walls to contain construction and remediation areas, the walls are discarded afterward. With skyrocketing lumber prices, this is an excess cost that adds up over time. With reusable containment walls, like the SHIELD WALL® System, companies can reuse the same containment walls for years in a row, saving money and promoting more sustainable business practices.

5 Years Later – How Abatement Technologies Aided Hurricane Maria

September is historically the time of year with the most optimal conditions for the formation of hurricanes in the mid-Atlantic region. Because of the high amounts of humidity and warm air in the Caribbean, its geographical location houses the perfect conditions for catastrophic hurricanes. In fact, this year marks the fifth anniversary of Hurricane Maria, the deadly Category 5 hurricane that devastated the northeastern Caribbean in September 2017.

As a result of Hurricane Maria, the island of Puerto Rico lost most of its essential services’ infrastructure, communities were leveled, many were displaced, and thousands of lives were lost. Five years after the disaster, the reconstruction and restoration efforts on the island are still ongoing. Following the immediate devastation in 2017, Abatement Technologies customer and restoration expert, Pat Dooley, was contracted to fly to San Juan, Puerto Rico, to do an assessment of the flood damage in the Mall of San Juan, a 1,580,000 square-foot shopping mall that first opened its doors in 2015. Upon initial assessment, Pat and his team discovered that nearly 18 inches of water had flooded the mall.

As a result of the hurricane, there were travel and equipment delays that prohibited Pat and his team from arriving in Puerto Rico until 14 days after the hurricane had already passed. Because mold incubates from a spore for 12 to 24 hours, and starts showing visual signs of growth in 48 to 72 hours, the team was challenged upon arrival with remediating severe mold growth. When remediating mold, it’s important to remove every spore to prevent regrowth. Because of this, workers had to cut and remove drywall and other materials, which lead to dust and other potentially harmful particles in the air.

In order to safely contain the mold, Pat and his team decided to bring in 100 of Abatement Technologies’ air filtration devices. These devices were situated throughout the mall to help remove any harmful particulates, bioaerosols and volatile organic compounds that were released into the air during the project. By leveraging this equipment, the team was able to help protect the short and long-term health of those involved and helped ensure that they were breathing the cleanest air possible.

As a remediation and restoration expert, Pat is an IICRC Instructor and is the founder of what is known today as the Applied Structural Drying Course. Leveraging his education and experiences, like the project in Puerto Rico, Pat has carried out water restoration projects with a total value of nearly $14.7 million and has participated in numerous natural disaster restoration projects. With a passion for helping and protecting people, Abatement Technologies is proud to work with remediation and restoration experts, like Pat, to deliver the best solutions available in the market.

The Top 4 Considerations When Evaluating Portable Air Scrubbers

Airflow ratings can be very misleading: The cheapest units are often the most costly

When purchasing portable air scrubbers for use on restoration and/or mold remediation projects, there are many factors that should be considered in selecting the proper piece of equipment. Too many times airflow (or claimed airflow) and price are the only issues considered before a purchase. All too often the contractor finds that the equipment does not meet their expectations or needs when it arrives.

1. Ease of transport

This is one of the most important, yet most overlooked, aspects of portable air scrubbers. Scrubbers must constantly be moved from job to job and from location to location during a project. Some units are designed for one-person operation; others may require two people to move. Weight is very important, but so is weight distribution. Scrubbers that include a transport system for easy movement by one operator are safer and more cost-effective to operate. A stair climber is also a valuable feature when stairs are a factor. Size and weight should also be considered when thinking about transport and vehicle requirements.

2. Air scrubber filtration system

The filtration system is the heart of a portable air scrubber. Poorly designed filtration can add hundreds or even thousands of dollars in annual operating costs. Filters must provide a substantial dirt-holding capacity and long filter life without significant airflow loss. A well-designed filtration system requires three stages of filters to progressively filter all particle sizes. If odors and particulates are to be removed simultaneously, a fourth stage of gas/odor filtration may also be needed.

Easy “no tools” access is important when inspecting and replacing dirty filters. The filter module should not have to be removed to change or inspect filters. This is time consuming and can also cause debris to be spilled onto the HEPA and the surrounding area.

HEPA filters must be individually tested by the filter manufacturer and certified to a minimum efficiency of 99.97% at 0.3 microns. It is not enough to simply assemble a filter using HEPA media. A true HEPA filter must be constructed to the exact manufacturing practices necessary to ensure that the finished filter does not leak through the filter media or around the frame or seams. If debris can bypass the HEPA media, the filter will not pass DOP testing required in many abatement specifications. Insist that the HEPA filter itself be certified to HEPA standards, with a certification label affixed to the frame of the HEPA filter.

3. Blower type

Air scrubbers are required to trap large quantities of debris. Debris buildup on the filters hinders the airflow and causes what is technically known as static resistance. Specific blowers are much better suited than others for overcoming this resistance. There are many types of air moving blowers available, each with specific characteristics for certain applications.

For example, forward-inclined “squirrel cage” blowers are designed to move large volumes of relatively clean air and low static resistance. These inexpensive blowers may be suitable for applications such as use in a furnace or even in an asbestos negative air machine; they are not, however, a very good selection for use in an air scrubber.

Backward-inclined or airfoil type blowers are a much better choice since they are engineered with the capacity to overcome the pressure drop of dirty filters. The use of this type of blower will not only increase filter life but will also produce higher airflow as the filters begin to accumulate debris. This generally means significantly better performance (airflow) over the life of the filters and much lower replacement filter expenses than a scrubber or negative air machine that is equipped with a forward inclined blower with a comparable peak airflow rating.

4. Materials and construction methods

Most negative air machines position the blower at the outlet of the cabinet, and pull air through the cabinet. This keeps the entire cabinet – including the section downstream from the HEPA filter - under lower (negative) pressure compared to the air in the surrounding area. With this design, the machine must be perfectly sealed to prevent contaminated air from being sucked into the cabinet and exhausted without ever passing through the HEPA.

This is a big concern when the unit is used as a negative air machine and exhausts air into another part of the facility, especially if that area is occupied. Any such leaks will negate the effectiveness of the HEPA filter and will more than likely cause contamination of the area and failure of any air testing required by the job specification. This should be an important liability concern of any mold abatement contractor.

Generally, the use of gaskets and solid rivets produce the most leak free cabinets. Beware of any cabinet that uses fasteners such as hollow pop rivets, or threaded fasteners such as sheet metal screws or nuts and bolts. These devices do not afford the airtight seal necessary to keep small particles from infiltrating a negative pressure cabinet.

Fun fact: It has been found that sub-micron particles can actually travel along the threads of a screw or bolt!

Lastly, make certain that any hardware, instruments, or transport system components that penetrate into the cabinet are sealed in such a way as to prevent any leakage or bypass. For more information on evaluating portable air scrubbers contact us!

The Secrets of Negative Pressure Containment

The average hospital lasts more than 40 years, and often as many as 100 years. If you've ever considered buying an old house, or seen others do it on TV, you know just how much renovation and maintenance they require. Now multiply the square footage by more than 10, and you can imagine how much renovation is consistently needed in hospitals not only to keep them going but to continually improve services and meet changing building requirements.

While renovation and maintenance projects may pose little more than an inconvenience to homeowners, they require special attention in healthcare facilities because of the danger that airborne particles, spores, and pathogens released into the air by construction pose to patients. In order to carry out essential construction and maintenance work without harming patients, construction zones must be sealed off from patients, and air must be filtered and diverted away from vulnerable patients.

To do this, facilities must perform Negative Pressure Containment.

What is Negative Pressure Containment?

By its very definition, a negative pressure room has more air exiting it then entering. There is less air inside the room compared to the other rooms, hence why it is negative. What this does is ensures that any airflow outside of the HEPA exhaust is flowing into the room to fill that vacuum. Because airflow can only flow in one direction through the cracks or designated makeup air locations, the contaminants cannot escape the room. Always check regulations when exhausting inside a healthcare facility as regulations can vary.

How to create Negative Pressure Containment

There are four key steps to creating negative pressure containment:

1. Construct a physical barrier around the area.

Product Tip: You can do this with Abatement Technologies' AIRE GUARDIAN® SHIELD

2. Seal off any HVAC Returns

Tip: This ensures that dirty air does not escape into the rest of the building.

3. Filter air in the sealed room with a portable air scrubber (PAS)

Product Tip: Use a HEPA-AIRE® or PREDATOR® series Portable Air Scrubber (PAS) from Abatement Technologies.

4. Use a PAS (portable air scrubber) to exhaust the filtered air out the construction zone through duct work

Critical Environment Protection

HEPA based high-quality air filtration equipment

A Critical Environment is any area where something can be easily affected by external contamination. Our experience working with companies that have to do dirty jobs in critical environments started in the 80's with asbestos abatement. The job of removing asbestos required contractors to enlist preventative measures to control dangerous dust particles and that's where we found our niche and specialty. Making high-quality air filtration equipment that incorporated HEPA filtration to remove 99.97% of any airborne particulate that was 0.3 microns or larger.

This created a natural expansion into healthcare construction, as infrastructures age the need to renovate facilities without shutting them, because these types of renovations would be happening alongside occupied patient areas and patients, especially those that are immunocompromised and susceptible to infection from the slightest airborne contamination our specialized equipment was again brought into play, by allowing contractors to contain their construction site and use negative pressure and HEPA level filtration to help prevent the spread of those dangerous contaminants to patient occupied areas.

Recently we have seen the expansion of what would be considered critical environments. These include Pharmaceutical Manufacturing and Storage Facilities, Electronics Manufacturing Facilities, Food and Beverage Manufacturing, Data Centers and Server Rooms as well as the expanded concern about construction around employees in any operational work environment.

Our high-end selection of HEPA based air filtration equipment, portable containment solutions, temporary barriers systems, and pressure monitoring equipment combined with our knowledgeable sales consultants make Abatement Technologies the perfect partner for a project in any critical environment.

US and Canadian workplace safety regulations require certified electrical equipment.

OSHA safety regulations in the U.S. and CAN/CSA regulations in Canada require all electrical device models used in the workplace to conform to applicable safety standards. This means that the device must be submitted by the manufacturer to an OSHA Certified Nationally Recognized Testing Laboratory (NRTL) such as UL, TUV, ETL or CSA for the specified certification testing.

HEPA filtration devices such as portable air scrubbers and axial and centrifugal air movers must conform to the UL507 “Fans and Blowers” standard. Devices with plastic cabinets (enclosures) that contain energized electrical components must be NRTL certified to conform to UL flammability standards (typically UL94HB) as well.

The unfortunate truth

A significant number of the HEPA filtration devices, air movers and other devices sold and in wide use today are not NRTL certified. This problem appears to be particularly prevalent with devices imported from Asia, but applies to some products made right here in North America as well. It’s possible that some of these products might comply if submitted to and tested by an NRTL, but it appears likely that at least some would fail.

It costs money to design and build products that can conform to these safety standards. Uncertified devices may be available at a lower price, but isn’t that like playing Russian roulette? Without the proper safety certifications how can you possibly know whether or not the product is safe? With all that could be at stake is the chance to perhaps save a few bucks up front a risk that you can really afford to take?

Product safety is one of our paramount concerns

That’s why each and every Abatement Technologies portable air scrubber and air mover model sold in the U.S. and Canada has been tested by a Nationally Recognized Testing Laboratory (NRTL) and certified to conform to UL507. All models made with polymer cabinets have also been NRTL tested and certified to conform to stringent UL94HB flammability standards.

Best Practices

All NRTL certified products must have an NRTL certification label attached to them to show that they are compliant. It might be a good time to take a few minutes to inspect your equipment and check for the labels. If they are not there it might be time to call your supplier and find out why. Or, it might be time to look for another brand that is certified.
