What is the minimum internal pressure that walls and ceilings must withstand in the presence of a deflagration hazard?

• A. 30 psi
• B. 40 psi
• C. 50 psi
• D. 60 psi

Answer: (C)

The minimum internal pressure that walls and ceilings must withstand in the presence of a deflagration hazard is specified at 50 psi. This value is derived from standards aimed at ensuring safety and structural integrity in environments where a rapid combustion reaction could occur. Deflagration refers to a combustion process that occurs at subsonic speeds and can produce significant pressure waves. If walls and ceilings are not engineered to withstand the impact of these pressure changes, structural failure can occur, leading to catastrophic consequences, including increased injury risk and damage to property. By establishing the minimum requirement of 50 psi, safety regulations seek to ensure that construction materials and designs are robust enough to handle the forces associated with deflagration. This provides a crucial level of safety for both personnel and property in facilities where such hazards are present.
