Explanation:

Define the S.I.N. acronym

The S.I.N. acronym is a standard safety protocol used for responding to hazardous material spills:

• Safety: Ensure the safety of yourself and others first.
• Identify: Identify the substance and hazards if safe to do so.
• Notify: Notify the appropriate authorities or departments.

Apply the first step

The question asks what you should do first according to this procedure.
The first letter S stands for Safety. Therefore, the immediate priority is to ensure everyone's safety by making sure people are out of harm's way.

Evaluate the options

• Option 1: "Ensure everyone's safety by making sure people are out of harm's way." This directly aligns with the S (Safety) step of the Emergency Preparedness protocol.
• Option 2: "Call the safety department..." aligns with N (Notify), which comes later.
• Option 3: "Call Environmental Services..." also aligns with N (Notify).
• Option 4: "Immediately begin cleaning up..." is unsafe for an unknown liquid.

Answer:

• (A) Ensure everyone's safety by making sure people are out of harm's way. (Correct answer)
• (B) Call the safety department to come identify the substance.
• (C) Call Environmental Services to clean up the spill.
• (D) Immediately begin cleaning up the spill with paper towels.
