After extinguishing a paint locker fire using the fixed CO2 system, which is the next action that should be taken to the space?

🔍 Key Concepts

• Fixed CO₂ systems and how they extinguish fires (removing oxygen) • Dangers of re-entering a space after CO₂ flooding (asphyxiation hazard) • Procedures to prevent re-ignition (reflash) in enclosed spaces like paint lockers

💭 Think About

• Think about what the atmosphere inside the paint locker is like immediately after CO₂ discharge. Is it safe to enter? • Consider what happens to hot surfaces and flammable vapors if you introduce fresh air too soon. • Ask yourself: which option reflects a standard safety practice for enclosed spaces treated with CO₂, before any entry or overhaul work?

✅ Before You Answer

• Verify that CO₂ systems work by displacing oxygen, making the space unsafe to breathe in at first. • Confirm that introducing air too early can cause a reflash, especially where flammable liquids or vapors are present. • Check which step logically comes before sending anyone into the space or disturbing contents, given both reflash and asphyxiation risks.
