• check if materials
to igniting and whether they require the use of local securities;
• seal with non-flammable materials any through-holes in installation, ventilation, etc., located in the
vicinity of the place of work;
• protect against welding spatter or mechanical damage all electric, gas and installation cables with
flammable insulation, provided that they are within the range of risk caused by fire hazardous works;
• check whether any painting or other works using flammable substances were not carried out on that
day.
Sparks may cause fires
Welding sparks can cause fires, explosions and burns to unprotected skin. Wear welding gloves and
protective clothing when welding. Remove or secure all flammable materials and substances from the
work area. Do not weld closed containers or tanks that have contained flammable liquids. Such
containers or tanks should be flushed before welding to remove flammable liquids. Do not weld near
flammable gases, vapors or liquids. Fire fighting equipment (fire blankets and powder or snow
extinguishers) should be located near the work area in a visible and easily accessible location.
Cylinders can explode
Use only approved gas cylinders and a properly functioning regulator. Cylinders should be transported,
stored and positioned upright. Protect cylinders from heat, tipping and mechanical damage. Keep all
parts of gas installation in good condition: cylinder, hose, fittings, regulator.
Welded materials can cause burns
Never touch welded parts with unprotected body parts. Always wear welding gloves and pliers when
touching or moving welded material.
4.3. Preparation of the workplace for welding
Caution! Welding can cause a fire or explosion.
• Observe the health and safety regulations for welding work and equip the workplace with an
appropriate fire extinguisher
• Welding in places where flammable materials can ignite is forbidden.
• Welding in an atmosphere containing an explosive mixture of flammable gases, vapors, mists or
dusts with air is forbidden.
• Remove all flammable materials within a radius of 12 m from the welding site and, if this is
impossible, cover the flammable materials with a non-flammable cover.
• Take precautionary measures against sparks and glowing metal particles.
• Note that sparks or hot metal splinters can penetrate through slots or openings in protective caps,
covers or screens.
• Do not weld tanks or barrels that contain or have contained flammable substances. Do not weld in
their vicinity either.
• Do not weld pressurized tanks, pressure lines or pressure tanks.
• Always provide sufficient ventilation.
• Make sure you are in a stable position before starting to weld.
4.4. Personal protective equipment
Caution! Arc radiation can damage the eyes or skin of the body.
• When welding, wear clean, oil-free protective clothing made of non-flammable and non-conductive
material (leather, thick cotton), leather gloves, high boots and a protective hood.
• Before welding, get rid of any flammable or explosive items such as propane-butane lighters and
matches.
