What is a crucial step before using chemical materials on job sites?

Reviewing safety data sheets (SDS) is an essential step before using chemical materials on job sites because these documents provide vital information about the properties and hazards of the chemicals, including how to handle them safely. Safety data sheets outline the necessary precautions to take, including personal protective equipment (PPE) required, first aid measures in case of exposure, and proper storage and disposal methods. Understanding this information helps ensure a safe working environment and protects workers from potential health risks associated with chemical exposure.

The other options do not emphasize the critical importance of safety and informed handling of chemicals. Skipping prior reviews would lead to an unprepared and hazardous situation. Solely following supervisor instructions does not necessarily ensure safety if those instructions are not based on reviewing SDS. Checking for employee opinions lacks the technical detail and safety protocols necessary for safe chemical handling, which can lead to miscommunication and potential accidents.
