US Air Quality Regulations

Diversitech - Air pollution control equipment that follows OSHA and NFPA guidelines and standards

Occupational Health & Safety Act (OSHA)    

The Occupational Health & Safety Act is a United States federal law that, among other things, regulates indoor air quality for all workplaces. OSHA publishes specific standards for ventilation and control of airborne contaminants, and offers guidance on other indoor air quality issues through “letters of interpretation”. CaliforniaNew Jersey, and Washington have state-specific indoor air quality regulations. All Diversitech fume extractors, downdraft tables, and dust collectors are designed and engineered to be 100% OSHA compliant.

National Fire Protection Association (NFPA)    

The National Fire Protection Association is an international non-profit agency that advocates adoption of over 300 harmonized codes and standards by all levels of government worldwide.  Diversitech's complete line of wet downdraft tables and wet dust collectors are recommended for combustible dust by these NFPA standards:


Chemical Safety Board (CSB)    

The U.S. Chemical Safety and Hazard Investigation Board is an independent US Federal agency which investigates industrial chemical accidents. The board has focused on many examples of combustible dust explosions detailing them in informative videos  Diversitech's wet downdraft tables and wet dust collectors could have prevented many dust explosions seen the in the videos below:

Environmental Protection Agency (EPA)    

The United States Environmental Protection Agency is an agency of the United States federal government that, among other things, protects human health and the environment. The agency also works with industries and all levels of government in a wide variety of voluntary pollution prevention programs and energy conservation efforts. The EPA enforces the Ckean Air Act which regulates air pollution and industrial emissions in the United States.

EPA regulations are particularly important when companies are researching wether or not they are allowed to exhaust pollutants outside their facilities or if they have to filter the air first. The EPA also enfroces laws on the disposal of solid and liquid hazardous waste.
