Which of the following is NOT considered a safe handling procedure for hazardous substances?

C is the appropriate choice because ignoring safety data sheets (SDS) poses significant risks when handling hazardous substances. Safety data sheets contain crucial information about the substances, including their hazards, handling precautions, emergency procedures, and first-aid measures. By not consulting or adhering to these sheets, individuals jeopardize their safety and the safety of others by not being informed about the correct procedures needed to mitigate risks.

In contrast, correct labelling, safe transportation, and proper storage practices are all vital components of safely managing hazardous materials. Correct labelling ensures that everyone who handles the substance is aware of its hazards and can take necessary precautions. Safe transportation guidelines protect individuals during the movement of hazardous materials, reducing the risk of spillages or accidents en route. Proper storage practices help to prevent accidents and ensure that hazardous substances are kept in conditions that minimize risk. All these procedures work together to create a safer environment when dealing with potentially dangerous materials.
