🔍 Key Concepts

• 46 CFR regulations on cargo handling spaces and machinery • Differences between spaces that are directly exposed to cargo vapors vs. spaces used only for storage or routing of equipment • How the Coast Guard treats potential sources of ignition like air compressors near flammable cargo systems

💭 Think About

• Which of these spaces is most likely to contain flammable vapors on a regular basis, even when cargo isn’t actively being loaded or unloaded? • Think about the function of an air compressor: could it be a source of heat, sparks, or ignition? In which of the listed spaces would that be most dangerous under Coast Guard rules? • Ask yourself whether the regulation targets only one specific situation or aims to cover a broader group of hazardous locations.

✅ Before You Answer

• Check in 46 CFR for language about machinery that may be a source of ignition near cargo systems • Verify whether the rule mentions enclosed spaces versus open or deck areas • Confirm if the regulation lists one specific prohibited space or uses wording that effectively covers multiple related cargo areas.
