Safety equipment locations and proper disposal instructions are also outlined in the MSDS. option a is correct.
Step-by-step explanation:
To find the proper firefighting measures for a hazardous substance on a worksite, employees should be able to consult the Material Safety Data Sheet (MSDS). The Material Safety Data Sheet provides essential information on how to work with different chemicals, including the potential dangers and the correct firefighting techniques specific to each chemical. Additionally, the MSDS contains instructions on the proper disposal of chemicals, preventing harmful environmental effects and personal safety risks.
Using water on all fires involving chemicals is not recommended as water can sometimes exacerbate certain chemical fires. Thus, the correct extinguishing method can be crucial and is detailed in the MSDS. Evacuating the area is a priority in any emergency, but knowledge of how to respond to the chemical incident comes from the MSDS guidelines. Supervisors should also be able to provide guidance, but the MSDS will have the most direct and detailed instructions. Finally, it's imperative to know where specific safety equipment, like fire extinguishers and eyewash stations, are located, and to understand that personal protective equipment is the last line of defense after engineering and administrative controls.
By consulting the MSDS, employees can ensure they are taking the necessary steps to handle emergencies involving hazardous substances safely and effectively.
