🔍 Key Concepts

• Self-contained breathing apparatus (SCBA) purpose and typical use on board vessels • Difference between supplying air to a person vs testing air quality in a space • Dangers of enclosed/confined spaces that may have toxic gases or low oxygen

💭 Think About

• Which choice best matches what firefighters or emergency response crew use when entering a smoke-filled space or a compartment with unknown fumes? • Does an SCBA measure air quality, or does it simply provide safe breathable air regardless of the surrounding atmosphere? • Think about which equipment would be used for underwater work versus fire/emergency response work on a vessel.

✅ Before You Answer

• Be clear on what SCBA stands for and what the "self-contained" part means. • Ask: Is the device being worn by a person to breathe, or is it testing the space to see if it is safe? • Eliminate any choice that clearly refers to a different specialized device (e.g., diving gear, resuscitators, or gas detectors).
