Blaze Through the NCCR Boilermaker Test 2026 – Forge Your Path to Success!

Keep oxygen and acetylene apart because oxygen makes fires burn hotter and faster, and acetylene is highly flammable. If a leak or accidental ignition occurs near both, the combination can rapidly escalate into a dangerous blaze. To reduce that risk, OSHA/NFPA require either keeping oxidizers and fuel gases at least 20 feet apart, or placing them on opposite sides of a noncombustible barrier that’s at least 5 feet high. That means, without a barrier, the minimum distance is 20 feet. The other distances fall short of this safety requirement.
