🔍 Key Concepts

• Safe handling of compressed gas cylinders on board vessels • Fire and explosion hazards when using oxygen and fuel gases • What standard welding safety practices say about securing cylinders, oil/grease, and temperature exposure

💭 Think About

• Think about which option actually reduces the risk of a cylinder falling, breaking a valve, or becoming a projectile. • Consider what happens if oxygen equipment comes into contact with oil or grease—does that increase or decrease fire risk? • Ask yourself which options describe a real industry-standard practice you have seen in welding shops or on vessels.

✅ Before You Answer

• Verify which practice is commonly required by OSHA/shipboard hot work procedures for gas cylinders. • Check whether oxygen fittings should ever have oil or grease on them. • Confirm which precaution directly addresses the danger of a cylinder tipping, falling, or being struck.
