What is the capacity in Gallons Per Minute that a Deluge Shower must be able to discharge continuously?

1. 20 GPM

2. 25 GPM

3. 30 GPM

4. 35 GPM

The correct answer is: 30 GPM

The correct answer is 30 gallons per minute, which aligns with the standard requirements for a deluge shower. Deluge showers are specifically designed for emergency situations, such as in industrial settings where there is a risk of chemical exposure or fire hazards. The capacity of 30 GPM ensures that adequate water is discharged to effectively decontaminate or cool down individuals quickly and efficiently. This volume of water is crucial for the deluge system to function properly, as it allows for immediate coverage over the affected area, thereby providing the necessary safety measures in emergency scenarios. The standards for these systems are established to maximize the efficacy of emergency showers while ensuring compliance with safety regulations.
