🔍 Key Concepts

• Safe oxygen range for enclosed/confined space entry under maritime safety standards • Difference between "normal" atmospheric oxygen and the minimum acceptable level for safe work • Risks of oxygen deficiency and why a safety margin is required

💭 Think About

• Think about what the normal oxygen content of clean air is and compare it with the options given. • Ask yourself: at what oxygen percentage do most maritime regulations consider an atmosphere to be safe for entry without supplied air? • Consider why regulations choose a value slightly different from normal air rather than exactly the same as normal air.

✅ Before You Answer

• Know the typical oxygen percentage in normal atmosphere (at sea level). • Recall the usual regulatory minimum range for safe confined space entry in marine regulations and industry standards. • Make sure the option you pick is not below the commonly accepted minimum safe range for human entry without breathing apparatus.
