What maximum temperature must WP be stowed below?

The maximum temperature for stowing white phosphorus (WP) is critical for safety and operational integrity. Stowing WP below 100 degrees Fahrenheit is essential because exposure to higher temperatures can lead to the ignition of the material. White phosphorus is highly reactive, and heat can cause it to self-ignite or degrade, creating hazardous conditions and risks of fire or explosion.

Maintaining the storage temperature below this threshold ensures that the material remains stable and safe for handling and use. Proper stowage practices, aligned with the guidelines that specify this maximum temperature, help prevent accidents and enhance safety protocols, particularly in environments where munitions are present.
