Certificate for various occupational categories

Asphalting

Asphalting and maintenance asphalting on roads often require heating the substrate with an open flame. This is not in accordance with the definition of hot work and is not subject to a certificate.

​

Car recovery

Car recovery carried out by a car recovery company or similar where there is e.g. a cutting torch or angle grinder is used, carried out in an environment where there is a risk of fire. Such work requires a certificate.

​

Car workshops

A workplace for builders, mechanics etc. with a rubbish rack in one corner, a stack of tires in the other corner and empty packaging on the workbench and other flammables, is not particularly suitable for hot work. There is then a requirement for a certificate. If the car repairer takes the welding equipment with him or to use it elsewhere in the workshop, outside the workshop, in the car owner's own garage, in a car park or the like, then it is not a specially adapted workplace. There is then a requirement for a certificate. There is no requirement for a certificate for hot work when the work is carried out in a specially arranged workshop room that forms a separate fire cell. The workshop room must have non-combustible surfaces.

​

Fire brigade

There is no requirement for a certificate for hot work carried out by the fire service as an emergency response as a fire and rescue service. When the fire service's crews use angle grinders, welding equipment etc. for repairs and maintenance on and in their own buildings, there is a requirement for a certificate.

​

Farmers and replacements in agriculture

The majority of farmers have safety regulations for hot works in their fire insurance contracts. A certificate is required when hot work takes place in an environment where there is a risk of fire. Certificates are also required for substitutes and others who carry out hot work on behalf of the farmer in environments where there is a risk of fire. There is no requirement for a certificate in a specially arranged workshop room designed as a separate fire cell with non-combustible surfaces.

​

Concrete roof tiles, concrete slabs etc

See tiles.

​

Container

A certificate is required for hot work in an open container.

​

Electricians and electrical fitters/energy fitters

For electricians and electrical fitters/energy fitters, the requirement for a certificate applies to hot work. There is a requirement for a certificate, e.g. when using a gas soldering iron in a control cabinet. Hot work in environments without fire risk does not require a certificate.

​

Tiles

Cutting ceramic tiles, concrete roof tiles, concrete slabs, stone slabs etc. with angle grinders and other equipment that can create sparks is work requiring a certificate.

​

Gold and silversmiths

Goldsmiths and silversmiths melt metal and metal alloys over gas flares, i.e. using an open flame. The work takes place in a fixed, organized workplace. The individual work also has very small dimensions. There is no requirement for a certificate. The same applies to dental technicians.

​

Floor installers

"Welding" of floor coverings with hot air is work requiring a certificate.

​

Induction heating

With the help of high-frequency current, metals can be heated, e.g. bolts and nuts. Induction heat is often used as an aid to loosen nuts and bolts that are firmly stuck and are difficult to loosen in any other way. When using a coil for heating bolts and nuts, local heating takes place and there will normally not be a requirement for a certificate. The prerequisite is that the work is carried out in accordance with the supplier's instructions.

​

Coppersmiths and tinsmiths

The liability insurance for the copper and tinsmith requires a certificate in hot works. Soldering with hot air and an open flame on roofs is work requiring a certificate. This applies to both new and previously thatched roofs. Soldering with a soldering iron without the use of an open flame and without hot air does not require a certificate.

​

Shrinking of pallet caps/plastic film

Shrinkage using hot air or an open flame requires a certificate in all environments with a fire risk, e.g. in a storage room. In an environment without fire risk, e.g. in a separate fire cell (ref. safety regulations), there is no requirement for a certificate.

​

Laboratory work

In a laboratory, e.g. heating test tubes or sterilizing work equipment over a gas flare, i.e. using an open flame. The work takes place in a fixed, organized workplace. The individual work also has very small dimensions. There is no requirement for a certificate.

​

Painters

Removing old paint with hot air is work requiring a certificate.

​

Offshore

The certification scheme does not apply to offshore operations.

​

Plastic welding

The manufacture and repair of tarpaulins, hoods for lorries etc. is usually done by "welding" plastic with hot air. This is work subject to a certificate.

​

Plumbers

Soldering with an open flame in an unprepared workplace requires a certificate. Soldering with a soldering iron without the use of an open flame and without hot air is not work subject to a certificate, even if the work takes place in an unprepared workplace.

​

Shipyard

Generally

The safety regulations for hot work with the requirement for a certificate apply to the scope of the Insurance Contracts Act. In practice, it includes virtually all land-based commercial and industrial activities. Buildings, cranes, wharf facilities etc. at a shipyard have insurance under the scope of the Insurance Contracts Act. If hot work is carried out on buildings, cranes, wharf facilities and other equipment, a certificate is required. If hot work is carried out on a machine part that has been transported into a fixed fire cell, specially designed for hot work, there is no requirement for a certificate.

​

New ships

The insurance companies' safety regulations for hot work do not apply to insurances that fall under the Norwegian Marine Insurance Plan. A current insurance policy under the Norwegian Marine Insurance Plan is construction risk for ships. The practical consequence of this is as follows: The ship itself, which is under construction, has construction risk insurance under the scope of the Norwegian Marine Insurance Plan. For welding, cutting and other forms of hot work on ships under construction, there is therefore basically no requirement for a certificate. When building ships in an early phase with mostly only steelwork, the risk of fire is small. During the fitting out phase, the risk of fire is significantly greater. Many shipyards have therefore received a requirement in their insurance agreements for a certificate also for ships under construction, cf. the individual insurance agreement. Many shipyards also require a certificate for all subcontractors who will carry out hot work for the shipyard. It is also the case that contracted labor will have, as appears from this labor's liability insurance, a requirement for a certificate - also when working on ships that have construction risk cover.

​

Repair of ships

Repair work with hot work on ships/boats carried out by the shipyard's own employees or other hired labor will normally be subject to a certificate. Boats/ships that have hull insurance through the Norwegian Marine Insurance Plan do not normally have regulated requirements for a certificate for repair work involving hot work carried out by the ship's own crews.

​

Forest users

If a machine operator who does not have liability insurance carries out repair welding on the forestry machine in the forest, there is no requirement for a certificate. If the work is done by a professional welder in the forest, the welder will have a requirement for a certificate in his liability insurance. If the work is done in the machine company's garage/building, regardless of who does the work, a certificate will be required. There is no requirement for a certificate for hot work when the work is carried out in a specially arranged workshop room that forms a separate fire cell. The workshop room must have non-combustible surfaces. It is recommended that machine operators who carry out hot work on forestry machinery have a certificate in hot work.

​

Grinding of skates

Grinding skates is usually done with special machines with emery discs that produce sparks. Such grinding is defined as hot work. If the grinding takes place in a non-industrial business, the grinding is basically defined as non-certificate hot work. However, it must be clarified with the building owner whether the insurance agreement contains requirements for hot works. See point 2 of the Safety regulations for hot works.

​

Stone slabs

See tiles.

​

Roofers

Roofing with the use of an open flame, hot air or with hot exhaust gas from combustion is work requiring a certificate.

​

Dental technicians

See goldsmiths and silversmiths.

​

Weed burning

Weed burning can be done with infrared radiation, hot air or flame. Equipment that emits a flame from a nozzle and equipment that emits a flame under a cover is hot work requiring a certificate. Equipment that produces a flame in a combustion chamber so that only the hot exhaust gas comes out of the nozzle or under a cover is also hot work requiring a certificate.

​

Water sampling

During the water sampling, a small gas burner with an open flame is used for a short time (10-15 seconds) towards the outlet of the tap to disinfect it. This use of gas burners is defined as hot work. In environments where there is no fire risk, this will not be work subject to a certificate. In environments with a fire risk, the work will be subject to a certificate.

​

Road maintenance

When maintaining road markings, an open flame is often used to remove existing markings. In environments where there is no fire risk, there is no requirement for a certificate. In environments with a fire risk, a certificate is required when hot work is carried out.

​

Vocational education - students and apprentices

There is no requirement for a certificate for students in vocational upper secondary school when carrying out hot work when the work takes place as part of the teaching under the direction of a teacher with a certificate. For an apprentice in a company, some insurance companies see it as requiring a certificate (in the same way as foreign labour), while other companies will not require a certificate as long as the hot work is done under the supervision of someone who has a certificate. For apprentices as for everyone else, it is decisive for the issue of liability and compensation whether the person concerned has been grossly negligent or not and whether there is a causal connection between the breach and the damage.

​

Vocational education - teachers

The vocational upper secondary schools' teaching rooms for metalworking only are considered fixed, specially designed workshop rooms. Thus, there is no requirement for a certificate for the vocational school teacher. If the teaching takes place in a room that is used for more than just metalworking, including woodworking, this is not to be considered a fixed, specially designed workshop room. There is then a requirement for a certificate for the vocational school teacher.
