Description	The list is based on the following regulations
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.	AFS 2023:10 6§5 AFS 2023:11 2§11 AFS 2023:12 6§12

Workplace

Question	Risk assessment:
	Low	Medium	High
1. Is the work planned and designed as far as possible in such a way that work with the arms above shoulder height is avoided?
2. Do you take regular breaks if the work is one-sided and statically stressful?
3. If welding occurs and cannot be avoided, should something be used to sit on, e.g. a stable stool, if possible?
4. Is the welding site shielded with non-combustible and, if necessary, noise-reducing material (e.g. screen, fire blanket, sheet metal or board) that protects others and the surroundings from sparks, welding glare and, if necessary, noise?
5. If combustible material cannot be removed, is it covered with fireproof material?
6. Are suitable fire extinguishing materials (e.g. fire extinguishers, blankets, thermally insulated gloves, etc.) readily available for all welding?
7. Is there a functioning and efficient extraction system for welding fumes, e.g. a fume-eater, that can be moved along? (Effective means that there is no visible welding fumes left after welding.)
8. Is protective equipment used in welding (e.g. visors, respirators and helmets, hearing protection, welding overalls, safety shoes, welding gloves)?
9. Are the hoses, gaskets, and valves of the welding equipment undamaged and functional?
10. Has the use of grinding machines been checked to ensure that there are no imbalances or wear that increase vibrations?
11. Can the risk of strong smoke development be reduced by:
a) Can the welding method be changed to one that generates less smoke?
b) Choose electrodes that emit less smoke.
12. If a smoke extractor is used, is it always correctly placed, close and no more than 3 dm from the arc so that the welding fumes are captured effectively? NB! If the distance is longer, the smoke is trapped poorly.
13. If it is so noisy during welding, grinding, or slag that hearing protection is needed.
a) Does the welder wear hearing protection?
b) Do other people working nearby wear hearing protection?
14. Is the reconductor located next to and together with the welding cable and at a distance from the welder, so that the welder is exposed to as low electromagnetic fields as possible?
15. When welding in confined and poorly ventilated areas,
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!)
16. In the case of electric welding (mig, mag, tig, mma, etc.) it is checked that
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.)
17. Are your hands kept warm and dry when working with vibrating machines?
18. If venting of gas-welded pipes is to be carried out (note: risk of high levels of suffocating carbon monoxide in the pipe), how can the work be carried out safely, e.g. by:
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?
19. If welding or cutting is to be performed on the workpiece, is it possible to remove the paint from the surface that will be heated by the welding or cutting?
20. If welding is to be done inside very hot objects, what measures should be taken to ensure the safety of the workers?
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?
21. If thorium alloy tig electrodes are used
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?
