Do not work in an enclosed space with the engine running. Observe the local traffic regulations (priority, roads, speed, etc.). The trucks and their equipment must only be operated and used for the purposes specified by the manufacturer and designed, in accordance with the marked capacity or. tensile force or load diagram requirements. Sufficient view when reversing. Adherence to work procedures for repairs and service. Follow the procedure for recharging the truck and batteries. Immediate interruption of work in the event of an explosive concentration. Workplace ventilation. Rehabilitation of operating fluid leaks. Elimination of the use of open flames and other sources of ignition in the immediate vicinity of flammable substances. Only work on electrically secured devices. Check the condition of the tires before driving. Restriction of access by unauthorized persons.

Flame and electric arc welding, flame cutting

Risk
Penetration of the flame into the hose, or reducing valve. Hose rupture, damage, ignition. Explosion, fire. Low gas mixture output velocity (nozzle clogging). Bottle heating, explosion in case the casing is exposed to stress exceeding the yield strength of the sheet. Fire, burns due to oxygen leakage through leaky and greasy bottle valve, burner valve. Burns, fire due to oxygen leakage by welding and cutting torches. Burns to various parts of the body if the mallet has soiled work clothes. Use of a damaged pressure reducing valve, rupture of the diaphragm and gas leakage. Burners of the welder or. other people with flame burner, fire. Fire by igniting the truck or its parts, fuel. Fire by igniting surrounding material or spilled operating fluids. Burns an unprotected part of the body (hand) by direct contact with a mallet with a heated cut, cut metal material and hot metal surfaces during heat transfer. Unbearable and unfavorable microclimatic conditions, especially in outdoor unprotected areas in summer, indoors, in areas with considerable radiant heat, etc. Damage to health due to radiation or welding fumes.

Measures
Only connect welding equipment that is designed and tested for this bottle. Using the right cutting torches. Deactivate the burner, which shows a repeated flashback. Do not use defective burners. The correct procedure for igniting and extinguishing the burner flame. Professional competence of welders. Valve closing when work is interrupted. Sufficient length of hoses, safe placement of bottles from the heat source. Oxygen cylinder valve tightness. Elimination of grease valve contamination. Tightness of hoses and connections, tightness check of hoses once every 3 months and tests for the highest working overpressure (0.8 - 1.5 MPa for oxygen hoses). Timely replacement of damaged, puffy, excessively cracked hoses. Firm and tight connection of hoses with hose clamps (clips, not wire). Protection of hoses against mechanical damage (punctures, etc.), burns and grease contamination. Do not use hoses shorter than 5 m or have a distance between the couplings shorter than 5 m. Wear proper work clothes and PPE. Do not open the valve with a sharp jerk. Do not use damaged pressure reducing valves (eg even if the pressure gauge protective glass is cracked).
