American Chemistry Council (ACC) members, including those who manufacture diisocyanates (DII), strive to create a safe and healthy workplace. In fact, research shows workers in the chemistry business are safer than workers in agriculture, retail, food stores and general merchandising business sectors.
Worker/Industry Health and Safety Guidance
Industry Resources
The following health, safety and environmental resources are primarily intended for those who work with MDI and TDI:
- Product Stewardship Library: The industry makes available important health and safety information about diisocyanates via our Product Stewardship Library.
- Asthma: Provides resources on diisocyanate-related asthma, including a recorded webinar on sensitization and diisocyanate-related occupational asthma.
- Hazard Communication: Includes resources related to OSHA Hazard Communication Standard (HCS), including topics such as worker training, labeling and Safety Data Sheets (SDS).
- Ventilation: Types of ventilation systems and helpful resources.
- Protective Equipment: Federal regulations and standards for the protection of workers, including resources and equipment sources.
- Industrial Hygiene: Includes information on air monitoring and diisocyanates biomonitoring. Discusses chemical sampling and analysis methods to assess workplace chemical concentrations, including resources from OSHA (includes Wipe Sampling Method, NIOSH, EPA, Center for Polyurethanes Industry (CPI) and the International Organization for Standardizations (ISO) on testing methods. Also includes ASTM Standards.
- Air Monitoring: Resources available to help with diisocyanates air monitoring.

Nomenclature for Diisocyanates
- Instruction Manual: Nomenclature for Diisocyanates TDI, MDI and Derivatives:
The Instruction Manual: Nomenclature for Diisocyanates TDI, MDI and Derivatives was written to assist those persons that manufacture, import, process, or distribute various forms of toluene diisocyanate (TDI), methylene diphenyl diisocyanate (MDI), and their derivatives. The manual is intended to help clarify the Toxic Substances Control Act (TSCA) Inventory listings for these substances, decrease the number of unnecessary premanufacture notices (PMN) that are submitted under TSCA, and encourage harmonization of terms.
