What should the air temperature not exceed during apparatus testing?

The recommended air temperature not to exceed during apparatus testing is 100 degrees. This guideline is in place because higher temperatures can affect both the performance of the equipment and the safety of those operating it. At elevated temperatures, water supply characteristics can change, including potential issues with cavitation in pumps or structural integrity in hoses. Additionally, testing in hot conditions can lead to increased strain on personnel, negatively impacting their ability to perform effectively and safely.

It is essential to conduct tests in a controlled environment to ensure that results are consistent and that the apparatus operates reliably under the conditions it would face in the field. By adhering to this temperature limit, fire service personnel can ensure that the equipment is being tested under optimal conditions, mirroring the operational environment as closely as possible while safeguarding the health and safety of the crew involved.
