Which of the following data is included on a material safety data sheet for a hazardous shipment?
A Material Safety Data Sheet (MSDS) provides important information about hazardous substances, including how to handle them safely, their potential health effects, and emergency procedures. One of the critical pieces of information included on an MSDS is how to contact the manufacturer of the substance for further information or in case of an emergency. This contact information ensures that individuals handling the substance can get immediate assistance or clarification if needed.
If a Code of Federal Regulations Standard does not specifically address a workplace hazard, which of the following must be invoked?
If a Code of Federal Regulations (CFR) Standard does not specifically address a workplace hazard, the general duty clause of the Occupational Safety and Health Act (OSHA) must be invoked.
