Operator Manual, Revision T-114
1.2. Plasma/oxy fuel gas cutting safety awareness
It is essential that ALL operators of the system are aware of the potential danger/risk associated with
Plasma/Oxy fuel Gas cutting operations. Keep “SAFETY” in mind!
1.2.1. Prevention of fire and explosion
1. Never cut in to pressurized cylinders or hermetically sealed containers. Check for flammable
liquids, gases, vapors and other combustible materials.
2. Ensure there is sufficient ventilation to safely use Oxy fuel gas or plasma cutting processes,
use fume extraction/forced air systems as required.
1.2.2. Safe use of gas pressure regulators
1. Prior to use, perform a visual check on the regulators, look for physical damage to the body/
gauges, check for a sticking pressure indicator, ensure the gauges are clean and dry.
Do not allow pressure regulators to come in to contact with oil or grease, this can lead
to spontaneous combustion.
2. Gradually open the cylinder/manifold valve (manifolds are used on multi-gas delivery
systems) allowing the regulator to be pressurized without causing a sudden violent shock that
can cause damage.
3. Check the pressure gauge dial to ensure the pressure indicator is not sticking, listen for gas
leaks. Do not use damaged or leaking pressure regulators.
4. Do not attempt the repair of pressure regulators. Specialist training and equipment is
required. Serious injury or death can result from tampering with the device.
1.2.3. Gas cylinder handling and storage
1. Never use cylinders that are damaged, have been used as rollers/supports or are leaking gas.
2. Cylinders should be stored/installed away from sources of heat, sparks, molten metal, and
open flame. Kept in an upright position, take measures to prevent them from falling, secure
using chains or other approved methods.
3. Cylinders are to be used for the specified purpose only.
4. Contact the cylinder supplier if there is difficulty in opening/closing the valve. Do not use
force.
1.2.4. Oxy fuel gas hose safety precautions
1. The hoses are color coded, RED for fuel gas and Blue for oxygen, the hose fittings have
dissimilar threads, the fittings on the fuel gas (RED) hose are “Left hand or Anti-clockwise”
threads, the fittings have a small groove machined in to the external surface as an
identification mark. The fittings on the oxygen (BLUE) hose are “Right hand or Clockwise”
threads.
