What must be checked during the inspection of sprinkler heads?

It is essential during the inspection of sprinkler heads to evaluate both the visible condition and the operational state. Checking the visible condition involves looking for signs of physical damage, corrosion, rust, or obstructions that could hinder the sprinkler’s effectiveness. This visual inspection is crucial in ensuring that the sprinkler heads are ready to function properly in an emergency situation.

On the other hand, assessing the operational state means verifying that the sprinkler heads are correctly installed and free from any impairments that could prevent them from activating appropriately. This could include ensuring that the heads are not painted over, which can adversely affect their performance, or that they are not hindered by any ceiling tiles or other obstructions.

By thoroughly checking both the visible condition and the operational state, a comprehensive understanding of the functionality and readiness of the sprinkler system is achieved, ensuring it will perform as intended during a fire incident. Hence, inspecting both aspects is critical for maintaining the integrity of the fire suppression system.
