20. RESOURCES

21. The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) RESOURCES The Global System for Hazard Communication. Background In 2003, the United Nations (UN) adopted the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). The GHS includes criteria for the classification of: health, physical and environmental hazards, as well as specifying what information should be included on labels of hazardous chemicals as well as safety data sheets. The United States was an active participant in the development of the GHS, and is a member of the UN bodies established to maintain and coordinate implementation of the system.

23. OTHER RESOURCES CAMEO CAMEO is a system of software applications used widely to plan for and respond to chemical emergencies. It is one of the tools developed by EPA’s Office of Emergency Management (OEM) and the National Oceanic and Atmospheric Administration Office of Response and Restoration (NOAA), to assist front-line chemical emergency planners and responders.

Database containing toxicology, hazardous chemicals, environmental health, and toxic release information.

Other NIOSH Databases: IDHL Database, NIOSHTIC-2, Emergency Response Safety and Health Database (ERSH-DB), etc.

24. ASSIGNMENT 1.Review and compare differences between the MSDSs for Chlorine, Benzene & Formaldehyde. 2. Which MSDS has more information and which one has the least information? 3.Which one, if any, requires the least amount of PPE for general operations? 4.For a spill, which MSDS provides you the most detail on mitigating the hazards? 5.In your opinion, which substance is more toxic? 6.Would feel comfortable using only the information provided in the MSDS?

25. STATE AND FEDERAL LAW INFORMATION The Texas Hazard Communication Act is Chapter 502 and 506 of the Texas Health and Safety Code. It is also known as the “Public Employer Community Right-to-Know Act” Compatibility with Federal Laws. In order to avoid confusion among manufacturing employers, public employers, nonmanufacturing facilities, and persons living in this state, the Texas Department of State Health Services shall implement the Manufacturing Facility Community Right-To-Know Act, the Public Employer Community Right-to-Know Act, and the Nonmanufacturing Facilities Community Right-to-Know Act compatibly with the federal Emergency Planning and Community Right-To-Know Act (EPCRA), which is also known as the Superfund Amendments and Reauthorization Act of 1986 (SARA), Title III (42 USC §11001 et seq.), and related regulations (Title 40, Code of Federal Regulations (CFR), Parts 355-370), promulgated by the United States Environmental Protection Agency (EPA).
