From industrial chemicals to everyday cleaning products, chemicals are present in nearly every workplace. NIOSH has been researching workplace chemicals ever since 1974 with the goal of providing a safe and healthy work environment. Among the areas studied by NIOSH are:

  1. Studies of engineering controls and personal protective equipment,
  2. Risk assessment,
  3. Communication,
  4. Health Hazard Evaluations (HHEs),
  5. Toxicity studies,
  6. Occupational epidemiology,
  7. Studies of how to measure chemicals in the work environment.

In addition to providing fundamental works relating to chemical management essential for a safe workplace, the Institute has produced a complete set of tools that will assist you in understanding and managing chemicals safely at work.

A comprehensive resource for guided access to NIOSH’s chemical research documents, such as Chemical Carcinogen Policy and NIOSH Skin Notations, the NIOSH Chemical directory can be found here. Additionally, NIOSH offers resources such as its Pocket Guide to Chemical Hazards, its Manual of Analytical Methods, and International Chemical Safety Cards. Engineered controls and personal protective equipment are also available.

NIOSH On Ozone

ozone physical chemical properties

The NIOSH safety and health standards are not legally enforceable in the United States. However, the NIOSH maintains recommendations for health and safety standards that may influence future law and OSHA regulations. The NIOSH recommends that exposure to ozone be:

*Maximum recommended exposure limit to ozone is 0.1 PPM

*Ozone levels of 5 PPM or more are considered dangerous to health or life

Respirator Approvals by NIOSH:

Up to 1 ppm

*Any supplied air respirator

*Any ozone rated cartridge respirator

Up to 2.5 ppm

 *Any powered air purifying respirator

  *Any supplied air respirator operated in a continuous flow mode

Up to 5 ppm

 *Add face mask to respirator

Entrance into Unknown Concentrations

 *Self-contained breathing apparatus with full face mask
