Which of the following is not a requirement for fire safety?

Monthly cleaning of fire extinguishers is a practice that may enhance the overall safety and functionality of these devices, but it is not typically classified as a formal requirement for fire safety regulations. Fire extinguishers must be inspected regularly, and certain maintenance tasks are mandated by laws or standards, but the specific frequency of cleaning does not generally fall within these regulatory requirements.

In contrast, regular testing of fire alarms ensures that they function correctly in emergencies, background checks for employees help ensure a safe environment, and the certification of electrical systems is crucial to prevent fire hazards caused by faulty wiring. Each of these aspects plays a vital role in comprehensive fire safety protocols, ensuring that both equipment and staff are prepared for fire prevention and response.
