SAFETY PRECAURIONS FOR COMPRESSED ARGON
When welding in TIG mode, argon is the most commonly used protection gas. Read
and adhere to these safety precautions and recommendations.
FIRST AID
Breathing
: Argon does not have a toxic effect on human. Higher concentrations can
cause asphyxiation, due to lack of oxygen. Symptoms of high concentration are loss
of movement and consciousness. The victim can not sense the asphyxiation. The
victim must be transferred to fresh air. Cover them with blanket, and make them lay
still. Call the doctor. If the victim stops breathing, give the victim CPR (a
combination of rescue breathing and chest compressions) or use an automated oxygen
resuscitator.
IN THE EVENT OF FIRE OR EXPLOSION
Danger
: fire may easily cause the fracture or explosion of the gas cylinder. Argon is
not flammable, or combustible.
Combustion products
: None.
Extinguishing
: Cool cylinders with water, spray from a protected place. Do not
approach cylinders that may be hot. Evacuate if cylinders cannot be cooled.
Suitable extinguishing media:
Water fog or fine water spray.
ACCIDENTAL RELEASE MEASURES
Personnel
: Evacuate area. Before dealing with spillage take the necessary protective
measures, inform others to keep at a safe distance and shut off all possible sources of
ignition. Contact supplier for specific assistance. Allow gas to escape to atmosphere,
preferably in an open remote location. When accessing the spillage area provide
breathing equipment, independent from surrounding air. If it is not possible, first
prove that the atmosphere is not contaminated.
Environment
: Try to stop further gas spillage. Prevent vented gas from re-entering
ventilation intakes, low-lying spaces, cellars, drains, sewers or similar. Argon does
not contaminate the environment.
Cleaning Method
: Allow gas to escape to atmosphere.
Handling and Storage
Storage
: Store cylinders upright in an enclosure, preferably outside of buildings,
protected from direct sunlight. Secure cylinders by chains or similar device to prevent
falling over. Store cylinders below 45°C. Keep away from flammable or combustible
materials. Keep away from vehicular traffic and other thoroughfares. Protect from
physical damage. Protect regulators and other fittings from impact.
