Using a cutting torch can be dangerous if proper safety measures are not followed. Understanding the risks involved is the first step in preventing accidents.

Using a cutting torch comes with several serious hazards that must be managed carefully to prevent injury or damage.
Fire and explosions are a major concern. Sparks, heat, and molten metal can easily ignite nearby combustible materials, and gas leaks may lead to dangerous explosions. While oxygen itself isn’t flammable, it intensifies combustion, making materials burn more rapidly and severely.
Burns are another common hazard. The flame produced by a cutting torch is extremely hot, and contact with the flame or hot metal can result in severe skin burns.
Toxic fumes and gases are generated during the cutting process. Inhaling these airborne contaminants can lead to respiratory irritation or more serious health effects, especially in enclosed or poorly ventilated spaces.
Cylinder risks should not be overlooked. Gas cylinders are under high pressure and can rupture or become projectiles if damaged, dropped, or improperly handled.
Eye injuries are a risk due to the bright flame, flying debris, and sparks. Without proper eye protection, workers are vulnerable to burns, irritation, and long-term vision damage.
OSHA Standard 1910.252(a)(2)(xiii)(C) Management shall recognize its responsibility for the safe usage of cutting and welding equipment on its property and insist that cutters or welders and their supervisors are suitably trained in the safe operation of their equipment and the safe use of the process.
Do not attempt to use a cutting torch unless you are trained and authorized. Always follow the instructions provided in the user manual for the equipment you are using. Failure to follow the manufacturer’s instructions may result in fire, explosion, asphyxiation, property damage, or personal injury.

Before using a cutting torch, it is essential to check all equipment and ensure a safe setup. Inspect all equipment before use. Do not use damaged, defective, or improperly adjusted cutting equipment.
Make sure levers and valves work properly, threads on equipment are clean (no grease or oil) and not deformed, gauges are intact and easy to read, regulator is clean and free of oil or dirt, and fittings are properly sized for the cylinder.
Make sure hoses are clean (no grease or oil) and ferrules are properly installed so the fitting does not slip inside the hose. Be sure all connections are tight.
OSHA Standard 1926.350(g)(2) Torches in use shall be inspected at the beginning of each working shift for leaking shutoff valves, hose couplings, and tip connections. Defective torches shall not be used.
Personal protective equipment (PPE) is essential when using a cutting torch to protect against burns, sparks, and flying debris. All clothing and gear should be free of grease, oil, solvents, or other flammable substances.
Workers should wear dry, heavy-duty welding gloves, leather leggings, and sturdy work boots. Flame-resistant clothing is a must and make sure to avoid cuffs and open pockets that can catch sparks.
Eye protection should include safety glasses with side shields and a face shield or welding goggles with the correct shade lenses.
OSHA Standard 1910.252(b)(2)(i)(B) Goggles or other suitable eye protection shall be used during all gas welding or oxygen cutting operations.
Depending on the work environment, additional PPE may include a respirator, fire-resistant hearing protection, and a head covering to shield the head and neck.

Cutting produces fumes and gases and breathing these in can be hazardous to your health. Keep your head out of the fumes and do not breathe in the fumes. Shut off the compressed gas supply when it’s not in use.
When working inside, ventilate the area and/or use local forced ventilation at the flame. If ventilation is poor, workers who are cutting should wear an approved air-supplied respirator.
Do not use a cutting torch in locations near degreasing, cleaning, or spraying operations. The heat from the cutting flame can react with vapors to form highly toxic and irritating gases.
Do not cut on sealed air conditioning or refrigeration systems unless all refrigerants have been removed from the system.
Work in a confined space only if it is well-ventilated, or while wearing an air-supplied respirator, and ensure there is a trained attendant nearby. Cutting fumes and gases can displace air and lower the oxygen level, causing injury or death. Test atmospheres in confined areas for explosive and toxic gases before using cutting equipment.

Fire hazards are a major risk when using a cutting torch, making it essential to follow strict safety precautions to prevent fires, explosions, and serious injuries. Perform cutting work on a fireproof surface and use heat-resistant shields to protect nearby areas.
OSHA Standard 1926.352(d) and 1910.252(a)(2)(ii) for Welding and Cutting. Suitable fire extinguishing equipment shall be immediately available in the work area and shall be maintained in a state of readiness for instant use.
Do not use cutting equipment with gases and pressures other than those for which it is intended. Do not a cutting torch if grease or oil is present on the equipment or if the equipment is damaged.
Use a striker (friction lighter) or another approved device to light the cutting torch. Do not use matches, a lighter, or hot work to light the cutting torch.
Keep the cutting torch flame and sparks away from the cylinder, regulator, and gas hose. Do not use a cutting torch in any area where flying sparks can come close to flammable material. Do not use a cutting torch where the atmosphere may contain flammable dust, gas, or vapors.
Do not cut on containers that have held combustibles, or on closed containers like tanks or drums.
When the cutting work is complete make sure to inspect area to ensure it is free of sparks, glowing embers, and flames.
Do not refer to oxygen as air and do not use oxygen as a substitute for compressed air.

Operating a cutting torch safely begins with proper preparation and understanding of the equipment.
Always refer to the manufacturer’s user manual for guidance on assembly, leak testing, operation, shutdown, and maintenance. Only use accessories that are specifically recommended by the manufacturer for your model of cutting torch to ensure compatibility and safety.
Before lighting the torch, perform a leak test on the system. This should be done every time the equipment is set up or a gas cylinder is replaced. Using check valves and flashback arrestors adds another layer of protection by preventing dangerous backflow of gas into the hoses.
While cutting, always be mindful of others in the area and stay focused on the task because distractions can lead to serious injuries. Never operate a cutting torch if you are tired or under the influence of drugs, alcohol, or certain medications.
Ensure the workpiece is properly supported using clamps or a stable platform. Do not attempt to hold materials by hand or against your body.
If a backfire occurs (a loud pop followed by the flame going out), shut off the torch immediately. Close the torch handle valves. Find and fix the cause before relighting the torch. Backfire can be caused by operating the torch at lower pressures than required, touching the tip against the workpiece, overheating the tip, or an obstruction in the tip.
A flashback (flame traveling back into the hoses) is extremely dangerous. Shut off the gas supply immediately. Find and fix the cause before relighting the torch. A flashback might be caused by a clogged tip, valves that are not functioning correctly, or incorrect gas pressure.
