GASES
Dangerous gases can be produced during welding, breathing these gases in can be hazardous to your health.

Shut off shielding gas supply when not in use.

Always ventilate confined spaces or use approved air-supplied respirator.

Do not weld in locations near degreasing, cleaning, or spraying operations. The heat and rays of the arc can react
with vapors to form highly toxic and irritating gases.
EMF- ELECTRIC MAGNETIC FIELDS
During welding, electric magnetic fields are created and can produce malfunctions in electrical components within the
area.

EMF created by welders may affect wearers of Pacemakers and other Implanted Medical Devices should keep
away.

Implanted Medical Device wearers should consult their doctor and the device manufacturer before going near
arc welding, spot welding, gouging, plasma arc cutting, or induction heating operations.
EXCESSIVE NOISE
Be mindful if your working area creates excessive noise.

Wear approved ear protection if noise level is high.

Any workers close by the area will also be effected by the noise and may also require hearing protection.
GAS CYLINDER/LINE DAMAGE
Shielding gas cylinders contain gas under high pressure. If damaged, a cylinder can explode. Since gas cylinders are
normally part of the welding process, be sure to treat them carefully.

Protect compressed gas cylinders from excessive heat, mechanical shocks, physical damage, slag, open flames,
sparks, and arcs.

Install cylinders in an upright position by securing to a stationary support or cylinder rack to prevent falling or
tipping.

Protect all gas lines from sparks, slag and open flames.

Open the cylinder valve slowly. Then slowly open regulator valve to avoid damage to the regulator.
