A chemical spill occurs near the dental office. What is the MOST appropriate immediate action for office personnel?

  1. Cover the nose and mouth with a cloth and proceed normally
  2. Turn on the ventilation system to reduce vapors
  3. Lie down on the ground below the level of vapors
  4. Run away from the building without any plan
Show answer and explanation

Correct answer: B. Turn on the ventilation system to reduce vapors

  • A. A cloth does not provide adequate protection against chemical fumes or vapors and may give false security. Proper respiratory protection (N95 or supplied air) is required for chemical exposures.
  • B. CORRECT. Activating the ventilation system helps dilute and remove chemical vapors from the area, reducing exposure risk. This is a basic engineering control for chemical emergency response. Personnel should also follow the office's emergency action plan, evacuate if necessary, and contact emergency services.
  • C. Lying on the ground is appropriate for smoke (which rises) but NOT for heavier-than-air chemical vapors, which may accumulate at floor level. The appropriate action depends on the specific chemical properties.
  • D. Uncoordinated evacuation without a plan risks exposure and injury. Personnel should follow established emergency action plan protocols.
