After extinguishers are used, what action should you take to prevent hazard in the space?

• A. Increase ventilation
• B. Ventilation
• C. Do nothing
• D. Open all vents

Answer: (B)

After a fire extinguisher is discharged, residual smoke, fumes, and the agent from the extinguisher can linger in the space, creating toxic or irritating air and possibly reducing oxygen. The main safety step is to ventilate the area to dilute and remove those contaminants, restore breathable air, and reduce the chance of health effects or re-ignition. Ventilating the space establishes air movement so fresh air flows in and contaminated air flows out. This is the standard, immediate action to prevent hazard after discharge. If conditions require more airflow, you can increase ventilation, but the essential first-action instruction is to ventilate. Opening vents can help with that, but the core idea is to ensure proper ventilation to clear the space.
