What does R-12 convert to when heated?

When R-12, also known as dichlorodifluoromethane, is subjected to high temperatures, it can break down into various products, one of which is phosgene. Phosgene is a toxic compound that was historically used as a chemical warfare agent and can be produced through the thermal decomposition of R-12.

This conversion to phosgene is crucial to understand because it highlights the potential hazards associated with the improper handling or exposure to high temperatures of refrigerants like R-12. Knowing that R-12 can produce such a dangerous chemical reinforces the importance of safety protocols when dealing with fire alarm systems that may incorporate these substances.

Understanding the breakdown products of R-12 emphasizes the significance of proper storage and handling procedures in fire safety, as well as the potential risks of fire during leaks or malfunctions in systems using this refrigerant. This context is vital for anyone involved in fire alarm supervision and safety protocols, ensuring they are prepared to manage and mitigate risks effectively.
