Personal protective equipment (PPE) is worn to reduce employees' exposure to hazards.  It can include headgear, eyewear, gloves, footwear, protective clothing, and respiratory equipment. The following resources provide information on regulations and guidance pertaining to PPE and resources for obtaining PPE. Not all of the information is specific to methylene diphenyl diisocyanate (MDI) and toluene diisocyanate (TDI). Always consult the product Safety Data Sheet (SDS) for guidance on specific PPE.

Federal Regulations

Federal regulations and standards for the protection of workers, including PPE standards, are promulgated by the U.S. Occupational Safety & Health Administration (OSHA).

Visit the Isocyanates page on the OSHA website for additional information and resources.

Federal Guidance on PPE

Guidance on providing PPE developed by federal agencies such as OSHA, the Centers for Disease Control and Prevention (CDC), and the National Institute for Occupational Safety & Health (NIOSH) includes the following:

Center for the Polyurethanes Industry (CPI) Resources

The Center for the Polyurethanes Industry (CPI) has developed general guidance on PPE when working with MDI and TDI.

Visit CPI's Resources and Document library for a complete listing of the resources available.

Information on Equipment Sources

NIOSH provides useful information about respirators, including a list of manufacturers that produce NIOSH-approved respirators. These manufacturers produce other types of PPE, such as protective clothing and protective gear for the head, eyes, ears, hands, and feet.  In addition, they may produce PPE other than respirators, which are not included on the NIOSH list.

The American Chemistry Council and the Diisocyanates Panel do not endorse any specific manufacturers, companies or products. If you have questions about PPE for a specific MDI or TDI application, consult with the supplier or manufacturer of that product.
