PHOSPHORUS (MOLTEN) Chemical compatibility with O-rings, rubbers, & plastics

Molten phosphorus is a highly reactive and hazardous substance used in various industrial processes, including the production of phosphoric acid, fertilizers, and flame retardants. It exists in several allotropes, with white phosphorus being the most reactive and dangerous form. Molten phosphorus is stored and handled under strict safety conditions due to its ability to ignite spontaneously upon exposure to air, causing severe burns and releasing toxic fumes. Proper protective equipment, such as gloves, goggles, and face shields, is necessary to prevent contact and inhalation. Storage should be in inert atmospheres or underwater to prevent oxidation. In case of spills or leaks, immediate containment and neutralization are required to mitigate hazards. Due to its high reactivity and toxicity, working with molten phosphorus demands rigorous safety protocols and trained personnel to handle emergencies effectively.
