Fugitive dust control & housekeeping: OSHA Combustible Dust National Emphasis Program approved NRTL Certification: the answer to Aluminum Dust hazards in Collision Repair Shops

CD-IT-85L DHPSince automakers turned to aluminum for car and truck chassis, a new hazard surfaced for collision repair shops. Indeed, aluminum dust is extremely combustible and may be the cause of devastating explosions. How should these shops address the issue of aluminum dust hazards? Their first step should be to look into OSHA's Combustible Dust NEP approved NRTL certified equipment like Tiger-Vac's "Wet Mix" immersion separators.

Introduced in 2008, OSHA's Combustible Dust National Emphasis Program (NEP) contains policies and procedures for inspecting workplaces that create or handle combustible dusts. These dusts may cause a deflagration, other fires or an explosion. Aluminum dust, like all other combustible dusts, falls under the OSHA NEP, which is a law in the US. These safety standards are found in Title 29 of the Code of Federal Regulations (20 CFR) and the provisions for Nationally Recognized Testing Laboratory (NRTL) Certification are generally in Part 1910 (29 CFR Part 1910). In this context, proper housekeeping methods include the use of a dust ignition protected industrial vacuum cleaner system. Policies and procedures of the OSHA NEP help protect workers by requiring equipment used is designed for safe use in the work place.

Hazardous locations where combustible metal dusts are present are classified Class II, Division 1, Group E. The recovery of combustible metal dusts must be performed with great care using OSHA approved NRTL certified equipment (See an example of a NRTL certified equipment’s Certificate of Compliance by clicking here). The shop owner can ask the manufacturer for a certified “Wet Mix” Immersion Separator designed for the safe recovery of aluminum dust. The user must then read the instruction manual in order to get familiar with the safe way of using the equipment.

Tiger-Vac's "Wet Mix" immersion separators use liquids to neutralize aluminum and other combustible metal dusts. Mineral Oil is commonly used as, in most cases; combustible metal dusts generate hydrogen gas in contact with water. If hydrogen gas is produced during the process the equipment must provide a way to allow for the escape of the gas that would otherwise build up pressure in the equipment and could cause an explosion. Workers Health and Safety is a top priority and must be ensured by getting the right type of equipment complying with the OSHA NEP.

North American First: Tiger-Vac gets portable vacuum cleaners certified for Class II Division 2 by OSHA approved NRTL

altDecember 8, 2014 - Tiger-Vac, manufacturer of industrial vacuum cleaners, is proud to announce that two of its flagship models, CWR-10EX (4W) and C-10EX (DT) MFS, have been officially certified by CSA, a Nationally Recognized Testing Laboratory (NRTL), as meeting OSHA's Combustible Dust NEP requirements. This certification meets America’s stringent regulation in industrial housekeeping and is a first in the domain.
Introduced in 2008, OSHA's Combustible Dust National Emphasis Program (NEP) contains policies and procedures for inspecting workplaces that create or handle combustible dusts. These dusts may cause a deflagration other fires, or an explosion. In this context, proper housekeeping methods include the use of a dust ignition protected, portable or fix industrial vacuum cleaner system.
Tiger-Vac's CWR-10EX (4W) and C-10EX (DT) MFS have both been tested and legally certified by CSA for use in Class II, Division 2, Groups F & G work environment. They are recognized as dust ignition protected, therefore meeting all of OSHA's Combustible Dust NEP requirements. In short, these vacuum cleaners are recognized and certified as a safe way to pick-up combustible dusts in a hazardous location.
CWR-10EX (4W) and C-10EX (DT) MFS feature stainless steel construction and HEPA or ULPA filtration. While CWR-10EX (4W) is rated for use in a cleanroom environment, it can be part of any housekeeping program in an industrial environment.
To have portable vacuum cleaners certified for Class II Division 2 by an OSHA approved NRTL is a North American first. While Tiger-Vac is proud of this achievement, the company hopes it will pave the way to further product certification and, ultimately, to much needed clarifications in a market where requirements for category of product is not always well understood by customers and manufacturers.

The recovery of Aluminum Dust with a “WET Mix Immersion Separator”

Nationally Recognized Testing Laboratory (NRTL).

 
What requirements does OSHA have regarding NRTL’s?

OSHA standard, which are law, contain requirements for testing and certification by NRTL’s.

An explosion proof vacuum cleaner and dust collector must bear an NRTL certification.  In this case it is Class II, Division 1, Group E.

This certification applies to the entire assembled piece of equipment and not only for the components.

The “Wet Mix” or also commonly called “Immersion Separator” uses liquids to neutralize, or render inert, metallic dusts.  In this case Mineral Oil can be used for all commercial alloys with the exception of Zirconium.

To recover Zirconium dust, water is the only neutralizing agent that should be used.   

On the other hand, water should not be used to neutralize aluminum.  If water is the neutralizing agent used to recover aluminum dust then hydrogen gas can be generated.  If this is the case then a device “valve” can be installed onto the piece of equipment to evacuate the hydrogen gas.

As per NFA 484, it is also suggested that NRTL certified equipment be used.  In this case an explosion proof portable vacuum cleaner for the recovery of aluminum dust, or any other metallic dust, into a dry collection bag as long as the quantity to be recovered is less than 5 lbs.

The recovered metallic dust must be disposed of after a maximum 8 hr shift.

Following this type of procedure not only complies with the Authorities Having Jurisdiction (AHJ), but also with the workplace Canadian Center for Occupational Health & Safety (CCOHS) or Occupational Health & Safety Administration (OSHA)
