Why are deluge systems considered suitable for hazardous occupancies?

Deluge systems are specifically designed to provide automatic fire suppression, making them particularly suitable for hazardous occupancies. These systems utilize open nozzles that are activated simultaneously when the detection system senses a fire. This allows for a large volume of water to be discharged very quickly over a wide area, which is critical in environments where potential fire hazards are high and rapid response is essential to control and extinguish fires.

In hazardous environments, the risk of a fire spreading rapidly is significant, and the automatic nature of deluge systems ensures that water is applied to the fire almost immediately upon detection. This quick response can help prevent extensive damage and may reduce the overall risk to life and property.

Other options presented do not adequately describe the advantages of deluge systems for hazardous occupancies. For instance, lacking supervision would not be a benefit; installation costs are generally secondary to the value of safety; and preventing water overflow is not a primary concern of these systems when effectively operated. The primary strength of deluge systems in hazardous areas lies in their immediate and substantial fire suppression capability.
