Final answer:
MSDS, now known as SDS under the globally harmonized system, was a document detailing the safe use and hazards of chemical products according to WHMIS 1988. It included information on handling, emergency procedures, and disposal to ensure safety and environmental protection. These sheets had to be provided by manufacturers and be accessible in the workplace.
Step-by-step explanation:
MSDS stands for Material Safety Data Sheet, which is now typically referred to as Safety Data Sheet (SDS) under the globally harmonized system. Under the Workplace Hazardous Materials Information System (WHMIS) 1988, the MSDS was a comprehensive document intended for workers and emergency personnel. It provided detailed information on the safe handling, potential hazards, and emergency procedures related to the use of chemical products. These data sheets included instructions for the safe use and potential hazards associated with a chemical product, including information on the composition, chemical properties, first-aid measures, reactivity, and control measures.
It was imperative for individuals working with chemicals to consult the MSDS to ensure they were taking the necessary precautions for their safety, as well as to understand the proper disposal methods to protect the environment. Disposal of chemicals needs to be conducted in a manner that aligns with safety guidelines and environmental regulations, as many chemicals cannot simply be washed down the sink without potential harm to the ecosystem.
Under WHMIS 1988, MSDS sheets were required by law to be provided by the chemical manufacturer or supplier and needed to be readily available in the workplace. The transition to the globally harmonized system has since turned the former MSDS into SDS, which still serves a similar purpose but with a standardized format for international use.
