You are about to enter a compartment to investigate a suspected smoldering fire. If you're not wearing a self- contained breathing apparatus, you should test the compartment's atmosphere to determine if there is/are __________.
• Atmospheric testing before entry into a potentially hazardous space • The three main concerns: toxicity, flammability/explosion, and oxygen level • Basic principles of confined space entry and fire investigation safety
• Before stepping into a space with a suspected smoldering fire, what are ALL the different ways the air could be dangerous to you? • Does fire only change the oxygen level, or can it also create other hazards in the atmosphere? • Think about what a gas detector or multi-gas meter is normally used to check for before entry into a compartment.
• List the three major atmospheric hazards: low oxygen, toxic gases/vapors, and flammable/explosive mixtures • Ask yourself: which of the answer choices covers every one of those hazards? • Verify that your choice matches standard safe entry procedures into enclosed or confined spaces on board ships.
