| Refrigerant is non-flammable. On the contrary, it has a fire-inhibiting or fire-extinguishing effect. Refrigerant decomposes when exposed to flames or incandescent surfaces. UV light can also decompose refrigerants (UV is emitted by electric arc welding). Products of this decomposition are poisonous and must not be inhaled. However, these chemicals irritate the mucous membranes, giving adequate warning of their presence. |
