Establishing any construction project is a careful balancing act between many legal, financial and social responsibilities. Firms not only have a responsibility to shareholders and business partners, but to their workers, the local authority and site neighbors in the wider community as well.

What makes dust so harmful for construction workers is that it’s a combination of particles from various materials used on project sites. These fine grains could be heavy metals, asbestos, pollen, silica and much more. 

Dust particles become airborne during indoor metalworking processes like welding and plasma cutting. They also become airborne during the manufacturing and processing of food, chemicals, pharmaceuticals and other dry products.

Recognizing dangerous combustible dust situations in manufacturing plants and processing facilities helps you to quickly observe and recognize an unsafe situation in everyday work environments, evaluate whether you and your coworkers are in harm’s way, and decide what steps are necessary to make the area safe. 

The issue of dust explosions has been a hot topic since the early 20 century. In a book published by the NFPA in 1922, titled Dust Explosions, the authors, David J. Price and Harold H. Brown, acknowledge the need for a vacuum that can withstand the rigors of an industrial environment.

As defined by OSHA, combustible dust is “a solid material composed of distinct particles or pieces, regardless of size, shape or chemical composition, which can present a fire or deflagration hazard when suspended in air or some other oxidizing medium over a range of concentrations.”

The LiteSpeed™ HZ is one of only two doors in the industry that is UL listed for hazardous rated environments.

The filters are especially suited to explosive dust applications, helping facilities conform to NFPA and ATEX requirements.
