What clearance should be maintained around sprinkler heads above large piles of combustible materials?

The recommended clearance around sprinkler heads above large piles of combustible materials is 1 meter. This distance is crucial to ensure that the sprinkler system operates effectively in the event of a fire. If combustibles are too close to the sprinkler heads, they can obstruct the spray pattern and reduce the sprinkler's ability to effectively suppress a fire.

Maintaining a clearance of 1 meter allows the water to disseminate widely and reach all areas of the fire without being impeded by any surrounding materials. It helps in preventing the accumulation of heat and reducing the risk of re-ignition since the flames need room to be actively controlled by the sprinklers. This standard setup complies with fire safety regulations to ensure optimal performance of the fire suppression system.
