Question 1 of 27070

When welding or burning with an oxy-acetylene torch, __________.

🔍 Key Concepts

• safe operating pressures for acetylene in welding systems • differences between oxygen and acetylene hoses and fittings • basic gas welding safety rules from standard shipboard practice

💭 Think About

• Which gas in an oxy-acetylene system has a well-known, specific maximum safe working pressure before it becomes unstable? • Do safety rules usually limit the pressure of both hoses equally, or is one gas considered more critical to limit? • Think about which fittings are often made deliberately different (thread direction, size) to prevent accidental cross-connection of gases.

✅ Before You Answer

• Identify which gas becomes dangerous or unstable above a certain PSIG even in normal use. • Check whether maritime/industrial practice uses reverse (left-hand) threads on fuel-gas connections, or on oxygen, to avoid mix-ups. • Confirm from a welding safety reference where the commonly cited 15 PSIG limit applies.

Question 1 of 27070

When welding or burning with an oxy-acetylene torch, __________.

it is important to remember that the oxygen cylinder and hose thread connections are left handed

never allow more than 15 PSIG pressure in the acetylene hose

never allow more than 10 PSIG pressure in the oxygen hose

it is important to remember that the acetylene hose thread connections are right handed
