Q

Which is TRUE for atmospheres laden with coal dust or grain dust caused by loading these cargoes?

🔍 Key Concepts

• Dust explosions in enclosed spaces such as holds or cargo handling areas • Difference between explosive, toxic, and spontaneous combustion hazards • Operational controls during bulk cargo loading (coal, grain, similar cargoes)

💭 Think About

• Think about what happens when very fine particles are suspended in air in the right concentration and then exposed to an ignition source. • Ask yourself: is every kind of dust automatically poisonous, or is the main hazard sometimes something else? • Consider whether coal or grain dust themselves suddenly ignite in mid‑air without a trigger, or whether they need a spark/heat source.

✅ Before You Answer

• Verify which option correctly describes a known hazard: dust + air + ignition source at certain concentrations. • Eliminate any choice that claims all dust is toxic; think of common, non‑poisonous dusts. • Check which option best matches standard safety guidance: controlling ignition sources and dust levels, rather than always halting loading.
