What is the requirement for the protection of sprinklers that are subject to mechanical injury?

Sprinklers that are exposed to potential mechanical injury, such as those installed in locations where they may be struck by equipment or materials, must be adequately protected to ensure their functionality and integrity in the event of a fire. The requirement for protection typically includes the use of listed guards specifically designed for this purpose. These guards help to prevent physical damage to the sprinklers while allowing them to operate effectively in case of an emergency scenario.

Utilizing listed guards not only complies with safety regulations but also ensures that the installed sprinklers maintain their operational capability and provide the necessary protection in the area served. This is crucial because any damage to a sprinkler can lead to system failures that would compromise fire safety measures. Thus, the use of proper protective measures is essential for maintaining the effectiveness of fire suppression systems.
