The pressure gauge is the component of a portable fire extinguisher that indicates the pressure of its contents, ensuring it is charged and ready for use.

After using a fire extinguisher, what should an employee do if the fire appears to be out but may still re-ignite?

Answer explanation

Backing a safe distance and watching for several minutes allows you to ensure the fire is completely out and prevents potential re-ignition. This is a crucial safety step before leaving the area.

If a fire re-ignites after being extinguished, which steps of the P.A.S.S. technique should the employee repeat?

• Repeat steps 1, 2, 3, and 4 of the P.A.S.S. technique if fire re-ignites.

• Repeat steps 2, 3, and 4 of the P.A.S.S. technique if fire re-ignites again.

• Repeat steps 1, 2, and 3 of the P.A.S.S. technique if fire re-ignites again.

• Repeat steps 3 and 4 of the P.A.S.S. technique if fire re-ignites after extinguishing.

Answer explanation

If a fire re-ignites, the employee should repeat Steps 2-4 of the P.A.S.S. technique: Aim at the base of the fire, squeeze the handle, and sweep side to side to effectively extinguish the flames.

What should an employee do if the fire progresses beyond the incipient stage or the extinguisher runs out of extinguishing agent while the fire is burning?

Answer explanation

If the fire exceeds the incipient stage or the extinguisher is empty, the safest action is to immediately evacuate. Continuing to fight the fire can be dangerous and may lead to injury.

Which of the following best describes the purpose of employee alarm systems in fire safety?

• To provide only visual signals during emergencies, without any audio or tactile alerts for employees.

• To include visual, audio, and tactile signals, alerting employees effectively during emergencies and fire situations.

• To monitor fire extinguishers monthly, ensuring they are functional and ready for emergency use always.

• To operate automatic fire suppression systems, activating them during fire emergencies to protect employees and property.

Answer explanation

Employee alarm systems are designed to alert staff using visual, audio, and tactile signals, ensuring everyone is informed during emergencies. This comprehensive approach enhances safety compared to just visual signals.

How often should employee alarm systems be tested if they are unmonitored?

• Employee alarm systems that are unmonitored should be tested every week to ensure proper functioning.

• Employee alarm systems that are unmonitored should be tested every month to ensure proper functioning.

• Employee alarm systems that are unmonitored should be tested every two months to ensure proper functioning.

• Employee alarm systems that are unmonitored should be tested every six months to ensure proper functioning.

Answer explanation

Employee alarm systems should be tested every two months if unmonitored to ensure they function properly and maintain safety standards. This frequency balances reliability and resource management.

Which statement correctly explains how portable fire extinguishers should be maintained?

• They must be tested every two months to ensure proper functioning and compliance with safety standards.

• They must be visually inspected every month to check for damage, tampering, or missing parts.

• They must be operated automatically without manual intervention, ensuring immediate response during fire emergencies.

• They must be connected to alarm systems for prompt notification and integration with building safety protocols.

Answer explanation

Portable fire extinguishers should be visually inspected every month to ensure they are in proper working condition. This regular check helps identify any issues before they become critical, unlike the other options listed.
