Q

When welding or burning with an oxygen-acetylene torch, the acetylene hose working pressure must not exceed __________.

🔍 Key Concepts

• Acetylene safety limits – why acetylene becomes unstable above certain pressures • Differences between working (hose) pressure and cylinder/storage pressure • Relevant OSHA/USCG guidance on maximum safe acetylene hose pressure when welding or cutting

💭 Think About

• Think about which pressure range is commonly used on a regulator when gas is actually flowing to a torch for normal cutting/welding work. • Eliminate any answer choices that are clearly too low to be practical for most cutting/welding operations. • Consider at what pressure acetylene is considered potentially unstable or unsafe in standard guidance.

✅ Before You Answer

• Recall the commonly cited maximum safe working pressure for acetylene in psi from safety manuals or class notes. • Check which value is often mentioned as the upper safety limit, not the typical operating setting. • Make sure you are thinking about hose working pressure, not cylinder pressure or regulator gauge rating.
