At what temperature should aluminum cylinders suspected of exposure be removed from service?

Aluminum cylinders are critical components in various fire service applications, and understanding their thermal limits is essential for safety. Aluminum begins to soften and lose structural integrity at elevated temperatures, which can significantly compromise the performance of the cylinder in emergency situations.

Removing aluminum cylinders from service above 350°F is a safety precaution informed by industry standards. At this temperature, the physical properties of aluminum can start to deteriorate, leading to potential failures that can endanger firefighters and others involved in operations. This is why 350°F is the established threshold; it provides a buffer to ensure that cylinders maintain their strength and functionality during use.

Temperatures above this threshold can lead to an increased risk of rupture or deformation, which could have dire consequences in a fire scenario. Thus, it's crucial for safety protocols to dictate that any cylinder suspected of exceeding this temperature should be taken out of service to prevent accidents and ensure the integrity of safety equipment.
