Prevents checklists

Welding temporary workplaces - parts 1 to 7

The checklist can be used in the planning and organisation of work at temporary workplaces. The checklist is also intended to support the work of developing routines for safer work. The checklist is divided into seven categories: 1) work management – planning and organization, 2) for the welder – control before the start of work, 3) the workplace – control of equipment and what is important when you are out on a jobsite, 4) functioning routines – the company's routines, 5) the welders' knowledge of the work environment – knowledge of routines on how to work safely, 6) equipment and protective equipment – instructions and tools, gas cylinders and clothing, 7) chemical products and transport.

Questions

Questions

a) Risk för fall?

b) Is the material free of explosive gases?

c) Influence from other professional categories?

a) Welding fumes?

b) Welding flash?

c) Radiation?

d) Welding fume?

Questions

a) Can the welding method be changed to one that generates less smoke?

b) Choose electrodes that emit less smoke.

a) Does the welder wear hearing protection?

b) Do other people working nearby wear hearing protection?

a) Are there written safety instructions?

b) Are respirators always used with P3 filters or compressed air-fed respirators?

c) Is compressed air breathing equipment used if the space is so cramped and poorly ventilated and there is so much welding gas that there is a risk of suffocation or poisoning? (P3 filters are not enough.)

d) Is the point extraction easily accessible and easy to use?

e) If a mobile smoke eater is used, is the exhaust air discharged outside the space? (Note: The smoke eater only removes particles, welding gases are not separated, so the exhaust air should be discharged outside the confined space.)

f) Is everyone aware that it is prohibited to use free-burning gas flames for heating? (Risk of deadly high levels of carbon monoxide.)

g) Is the space well-ventilated when using shielding gas? (Note: the shielding gas can displace the oxygen if the room is poorly ventilated, which can be fatal!)

a) Is the workplace dry?

b) Is the reconductor connected correctly?

c) Is the welding unit flawless?

d) Is the electrode holder ever placed on any metallic object that is connected to the electrical circuit?

e) Are electrical cables, including reconductors, routed in a way that protects them from damage, such as from hot or sharp objects, embers, and are they placed under a protective plate if they are on the floor?

f) Is this rule being followed, as everyone knows that it is not allowed to have welding cables hanging over your shoulder or use the cable reel as a seat? (Note: unnecessary risk of electromagnetic fields.)

a) Lead the exhaust air out via a hose connected to the vent valve, and does the air exit outside?

b) Is the space where the exhaust air is led ventilated before anyone enters it?

c) Are carbon monoxide gas detectors used to quickly detect if carbon monoxide levels are getting too high?

a) For example, are heat-insulating gloves and some type of ventilated suit with a hood made of fireproof material used?

b) Is there access to thermal insulation that can be used in cold welding?

a) Are the electrodes stored in sealed containers?

b) Is welding with alternating current avoided?

c) Is the grinding dust extracted and treated as environmentally hazardous waste when grinding or welding?

Questions

a) Are protective equipment in the form of visors, respirators, protective clothing, safety shoes, and welding gloves required?

b) Does the welding equipment have integrated extraction in the welding gun or a smoke eater?

c) Do you need lighting?

d) Extra warm clothes are required for work in cold conditions, such as in cold rooms or outdoors during winter.

a) When can welders work alone and when are they allowed to do so?

b) Is there a requirement for the welder to be reachable and able to reach others if necessary when working alone?

a) To check that the welding equipment, including hoses, gaskets, and valves, is undamaged and in good condition?

b) Maintenance of the equipment used in welding?

c) Is the airflow required to be 100 cubic meters per hour at a maximum distance of 1 dm, 600 cubic meters per hour at a distance of 3 dm, and at least 1,000 if the distance to the arc is 5 dm?

a) Are you exposed to noise above the limit value or at risk of hearing damage?

b) Are you exposed to vibrations at work above the limit value or if vibration injuries are suspected?

c) Are you referring to welding on materials that are or are suspected to be lacquered with polyurethane varnish?

d) Do other materials such as polyurethane or epoxy produce toxic airborne compounds when heated during welding?

Questions

a) Is it necessary to clean the surface being heated before welding, especially when welding a surface-treated or oily workpiece?

b) Are there any specific safety measures to be taken during welding in containers containing, for example, chlorinated solvents or in other areas where chlorinated hydrocarbons may be present? (Note: risk of formation of the combat gas phosgene and other dangerous substances.)

c) Gas welding in confined spaces can pose a serious risk of dangerously high levels of carbon monoxide.

d) Welding in specific materials, e.g. galvate (zinc chills), aluminium (ozone formation), stainless (carcinogenic chromium in the welding fumes) and non-alloy steel and manganese alloy steel (manganese that can affect the

a) Can the vibrating machines operate without exceeding the limit value?

b) Is the noise above the limit value?

Questions

a) Are the gas cylinders placed in racks or gas carts during work?

b) Are gas pipelines marked to prevent confusion between oxygen and fuel gas?

c) Are the tightness of fuel and oxygen hoses and fittings regularly checked?

a) Are there silent and low-vibration pneumatic slag hoes available and used, or hand hoe instead of pneumatic slag hoe (Knarren)?

b) Is there a vibration-damped sander available, and is there a vibration-damped support handle that also has a vibration-damped support handle?

c) Do pneumatic grinders have silencers for the bleed?
