What is the correct response when fire extinguishers are subject to malicious use?

The correct response involves keeping fire extinguishers in locked cabinets with emergency access because this measure helps to prevent malicious use while still ensuring that they are accessible in case of a fire emergency. Fire extinguishers are crucial for safety and should be readily available, but locking them up can deter vandalism or tampering, which compromises their availability and functionality.

In emergency situations, it's important that those who are trained can access the extinguishers without undue delay, which is why having emergency access is vital. The locking mechanism should not impede a swift response in a fire event, thus maintaining safety while reducing the risk of misuse.

The options that suggest replacing extinguishers immediately or keeping them unlocked do not address the balance needed between safety and accessibility. Additionally, suggesting that extinguishers should not be used until inspected overlooks the need for prompt readiness in emergencies.
