Question: 1 / 400

If a gauge indicates a pressure below the acceptable range, what is required?

It should be replaced immediately

It should be re-calibrated

When a gauge on a fire extinguisher indicates a pressure below the acceptable range, it is essential to have the extinguisher serviced. Gauges provide critical information about the internal pressure of the extinguisher, which is necessary for its effective operation. A reading below the acceptable range suggests that the extinguisher might not function properly in an emergency situation.

Thus, servicing is required to determine the cause of the low pressure and ensure the extinguisher is in good working order, whether that be recharging, repairing, or replacing the unit as needed. This process is vital for maintaining safety compliance and reliability in fire extinguishing equipment.

It's important to ensure that the extinguisher is ready for use, as attempting to use a fire extinguisher that is outside of the acceptable pressure range could lead to failure to operate correctly during a fire incident.
