Regulations & SafetyCâu 49 / 240
Which personal protective equipment (PPE) is most appropriate whenever a technician handles pressurized refrigerant?
a.Safety glasses (or goggles) and refrigerant-rated gloves
b.A hard hat only
c.Sandals and short sleeves for comfort
d.No PPE is needed for HFCs
Giải thích
Because pressurized refrigerant can cause frostbite and eye injury, technicians should wear safety glasses or goggles and refrigerant-rated gloves whenever handling it. A hard hat alone does not protect eyes or hands, sandals and short sleeves leave skin exposed, and PPE is still needed for HFCs. Proper PPE is a basic safe-handling requirement for all refrigerants.
