What is the minimum clearance required between automatic sprinklers and piles of combustible fibers?

The minimum clearance required between automatic sprinklers and piles of combustible fibers is three feet. This distance is crucial because it ensures that the sprinklers can effectively distribute water over the area where a fire may ignite. If the piles of combustible fibers are too close to the sprinklers, they may block the water from reaching these materials effectively, leading to inadequate fire suppression during a fire incident. A clearance of three feet allows for proper operation of the sprinklers and maximizes their effectiveness in protecting the area from potential fire hazards. This standard is often established in fire safety codes to enhance safety in environments where combustible materials are stored or used.
