🔍 Key Concepts

• 46 CFR requirements for "enclosed classified locations" on Mobile Offshore Drilling Units (MODUs) • Meaning of a "complete change of air" in a ventilation context • Why hazardous/classified spaces (with flammable vapors) require more frequent air changes than normal machinery spaces

💭 Think About

• Think about how quickly flammable or explosive vapors could build up in an enclosed classified space if ventilation is too slow. • Compare typical air-change requirements for ordinary machinery spaces versus spaces specifically classified as hazardous on a MODU. • Ask yourself which of these time intervals would most likely be considered safe and practical to keep vapor concentrations below dangerous levels.

✅ Before You Answer

• Verify in 46 CFR the specific air-change requirement for enclosed classified locations on MODUs, not just any enclosed space. • Check that you are looking at the section that deals with ventilation design and capacity, not fire protection or alarms. • Confirm that the chosen time interval reflects a relatively rapid and continuous air exchange appropriate for an area with potential flammable atmospheres.
