S-3 Hypertherm Safety and Compliance
SAfetY
English
fire prevention
• Be sure the area is safe before doing any cutting. Keep a fire
extinguisher nearby.
• Remove all flammables within 35 feet (10 m) of the cutting area.
• Quench hot metal or allow it to cool before handling or before letting
it touch combustible materials.
• Never cut containers with potentially flammable materials inside –
they must be emptied and properly cleaned first.
• Ventilate potentially flammable atmospheres before cutting.
• When cutting with oxygen as the plasma gas, an exhaust ventilation
system is required.
explosion prevention
• Do not use the plasma system if explosive dust or vapors may be
present.
• Do not cut pressurized cylinders, pipes, or any closed container.
• Do not cut containers that have held combustible materials.

WARNING
Explosion Hazard
Argon-Hydrogen and Methane
Hydrogen and methane are flammable gases that present an explosion
hazard. Keep flames away from cylinders and hoses that contain
methane or hydrogen mixtures. Keep flames and sparks away from the
torch when using methane or argon-hydrogen plasma.
WARNING
Explosion Hazard
Underwater Cutting with Fuel Gases
• Do not cut under water with fuel gases containing hydrogen.
• Cutting under water with fuel gases containing hydrogen can result
in an explosive condition that can detonate during plasma cutting
operations.
WARNING
Hydrogen Detonation with
Aluminum Cutting
• Do not cut aluminum underwater or with water touching the
underside of the aluminum.
• Cutting aluminum underwater or with the water touching the
underside of the aluminum can result in an explosive condition that can
detonate during plasma cutting operations.
CoMPReSSeD GAS eQUIPMeNt
SAfetY
• Never lubricate cylinder valves or regulators with oil or grease.
• Use only correct gas cylinders, regulators, hoses and fittings
designed for the specific application.
• Maintain all compressed gas equipment and associated parts in
good condition.
• Label and color-code all gas hoses to identify the type of gas in
each hose. Consult applicable national and local codes.
GAS CYLINDeRS CAN
eXPLoDe If DAMAGeD
Gas cylinders contain gas under high pressure. If damaged, a cylinder
can explode.
• Handle and use compressed gas cylinders in accordance with
applicable national and local codes.
• Never use a cylinder that is not upright and secured in place.
• Keep the protective cap in place over valve except when the cylinder
is in use or connected for use.
• Never allow electrical contact between the plasma arc and a
cylinder.
• Never expose cylinders to excessive heat, sparks, slag or open
flame.
• Never use a hammer, wrench or other tool to open a stuck cylinder
valve.
