A person may operate an air compressor in...

🔍 Key Concepts

• Hazardous locations on tank vessels under 46 CFR (especially spaces near cargo tanks, valves, and pump rooms) • How ignition sources (like electric motors on compressors) are controlled around flammable cargoes • Differences between cargo handling spaces and separate machinery spaces on tank barges

💭 Think About

• Which of these locations is most directly connected to the cargo system where flammable vapors are likely to be present? • Where would regulations be most strict about placing sparking or motor-driven equipment such as an air compressor? • On a tank barge, which type of space is normally designed and arranged to contain machinery and equipment, rather than cargo or cargo piping?

✅ Before You Answer

• Check which spaces are defined or treated as cargo pump rooms or cargo areas versus independent machinery spaces • Verify how close you are allowed to place potential ignition sources to cargo tanks, valves, and piping • Confirm which space is normally segregated and protected from cargo vapors by structure and ventilation design

A person may operate an air compressor in which of the following areas on board a tank barge?

Pump room

A space adjacent to a cargo tank

A space two meters from a cargo valve

Generator room
