Which of the following is NOT part of the monthly inspection routine for fire extinguishers?

The process of conducting monthly inspections for fire extinguishers primarily focuses on ensuring that the extinguishers are in proper working condition and ready for use. This involves a few critical steps that contribute to the overall safety and effectiveness of fire extinguishers in an emergency situation.

Visual inspection for damage, checking the pressure gauge, and inspecting hoses and connections are all essential components of this routine. A visual inspection allows the inspector to identify any physical damage, corrosion, or leakage that may jeopardize the extinguisher's functionality. The pressure gauge indicates whether the extinguisher is adequately charged and operational, which is crucial for effective fire response. Inspecting hoses and connections ensures that there are no blockages or deterioration that might hinder the performance of the extinguisher during use.

On the other hand, checking historical usage records does not form part of the monthly inspection routine. This activity pertains more to maintenance records than immediate operational readiness. While keeping track of historical usage is important for overall fire safety management and compliance, it does not directly impact the monthly assessment of an extinguisher's ability to function when needed.
