Okay, контекст. Но он длинный.
Welding and Burning Equipment Welding, open flame, or spark-producing work shall be done by Authorised Operators only.
People performing burning or welding and people assisting them must be wearing suitable clothing made of natural fibre such as cotton. Arms and hands must also be protected. For clothing suitable to be worn while welding and burning in an area requiring “flame-resistant” clothing, contact the XXXXXXXX Contact.
All exposed combustible materials around and below welding and burning areas shall be removed to a safe location, covered with fire-retardant material, or protected by containing all sparks and slag in a spark-catcher.
Each welder and burner is responsible for containing sparks and slag. A fire watch may be necessary. He shall have fire-extinguishing equipment available and be trained in its use and be familiar with facilities for sounding an alarm. He shall extinguish a fire only when obviously within the capacity of the equipment, or otherwise sound the alarm.
One fully charged fire extinguisher shall be provided by the Contractor and shall be within 2 m of any welding, burning or open flame work. Personnel shall be trained in the operation and use of the fire extinguisher.
Hoses and welding leads should not pass through doorways. If there is no alternative, the door shall be braced open and the hoses and leads protected from damage.
Welding or burning shall not be done on a closed vessel or tank, or on any vessel or tank previously in use unless it has been decontaminated and approval is given by the XXXXXXXX Russia Contact.
Welding leads, burning hoses and compressed air hoses shall be bridged over or shall be supported a minimum of 3.3m above passageways. Leads and hoses shall not be hung from conduit, process lines, sprinkler lines etc.
All leads, earth connections, clamps, welding machines, hoses, gauges, torches and cylinders shall be inspected by the user before use.
All fittings, couplings and connection shall be “leak-free”.
Ventilation shall be adequate for the material being welded or burned. Personnel should avoid breathing fumes. An exhaust system, blower or respirator should be used as required. Before welding or burning any material that has been painted, the presence of lead must be determined by field test or laboratory analysis.
Areas shall be checked ½ hour after welding and burning is done to ensure that a safe condition exists.
