Hot work in workplaces where there is a risk of fire occurring requires a certificate in
the scheme "Fire protection when carrying out hot work". This guide provides an overview of
some occupational categories, and describes whether there are requirements for a certificate within these categories. In addition
This document describes the use of certain types of work equipment whether or not a certificate is required, and
whether a certificate requirement may be triggered. The list is not complete, so it must always be checked
with the insurance agreement whether the work in question is subject to certification.

Asphalting
Asphalting and maintenance asphalting on roads often requires heating the substrate with open
flame. This does not comply with the definition of hot work and is not subject to certification.

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

Car repair shops
A workplace for builders, mechanics, etc. with a trash rack in one corner, a stack of tires in
the other corner and empty packaging on the workbench and other flammables, are not particularly
adapted for hot work. A certificate is then required. If the car repairer brings
the welding equipment etc. to use it elsewhere in the workshop, outside the workshop, in the car owner's own
garage, in a parking lot, etc., it is not a specially adapted workplace. It is then
certificate requirement. There is no requirement for a certificate for hot work when the work is carried out in a special
adapted workshop room that constitutes a separate fire cell. The workshop room must have non-combustible
surfaces.

Fire department
There is no requirement for a certificate for hot work carried out by the fire department as an emergency response in
property of fire and rescue services. When fire crews use angle grinders,
welding equipment, etc., when carrying out repairs and maintenance on and in your own buildings, a certificate is required.

Farmers and agricultural workers
The majority of farmers have safety regulations for hot work in their fire insurance contracts. It
A certificate is required when hot work takes place in an environment where there is a risk of fire.
There are also requirements for certificates for relief workers and others who perform hot work on behalf of the farmer in
environments where there is a risk of fire. In a specially designed workshop room designed as a separate
For fire compartments with non-combustible surfaces, a certificate is not required.

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 when performing hot work.
There is a requirement for a certificate, for example, when using a gas soldering iron in a switchboard cabinet. Hot work in environments without
Fire risk is not subject to certification.

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

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

Floor layers
"Welding" of floor coverings with hot air is work that requires a certificate.

Induction heating
Using high-frequency current, metals can be heated, e.g. bolts and nuts. Induction heating
Often used as an aid to loosen nuts and bolts that are firmly attached and difficult to get to.
loosened in any other way. When using a coil to heat bolts and nuts, a local
heating and will not normally require 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 copper and tinsmiths requires a certificate in hot work. Soldering
with hot air and open flames on roofs is work that requires a certificate. This applies to both new and older
thatched roofs.
Soldering with a soldering iron without the use of an open flame and without hot air is not subject to certification.

Shrinking of pallet caps/plastic film
Shrinkage using hot air or open flame requires a certificate in all environments with
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, for example, heating test tubes or sterilizing work equipment is carried out over
gas torch, i.e. with the use of an open flame. The work takes place at a fixed, adapted workplace. The individual
The work also has very small dimensions. There is no requirement for a certificate.

Painters
Removing old paint with hot air is work that requires a certificate.

Offshore
The certification scheme does not apply to offshore operations.

Plastic welding
The manufacture and repair of tarpaulins, truck covers, etc. is often carried out by
"Welding" of plastic with hot air. This is work that requires a certificate.

Plumbers
Soldering with an open flame in an unprepared workplace requires a certificate. Soldering with
soldering iron without the use of an open flame and without hot air, is not work requiring a certificate even if
The work takes place in a non-adapted 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, quay facilities, etc. on a
shipyards have insurance policies under the scope of the Insurance Contracts Act. If
If hot work is carried out on buildings, cranes, quay facilities and other equipment, there are requirements
to the certificate. If hot work is carried out on a machine part that has been transported into
a fire cell that is fixed, specially adapted for hot work, there is no requirement for
certificate.

New ships
Insurance companies' safety regulations for hot work do not apply
insurances that fall under the Norwegian Marine Insurance Plan. A current insurance under
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 Norsk
Marine Insurance Plan Scope. For welding, cutting and other forms of hot work
on ships under construction, there is therefore no requirement for a certificate in principle. When building
For ships in an early phase with mostly only steelwork, the fire risk is small.
During the outfitting phase, the risk of fire is significantly greater. Many shipyards have therefore been required to
their insurance contracts regarding certificates also for ships under construction, cf. the individual
insurance agreement. Many shipyards also require certificates for all subcontractors who
will perform hot work for the shipyard.
It is also the case that hired labor will have, as is evident from this labor's
liability insurance, a requirement for a certificate – also when working on ships that have construction risk coverage.

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

Foresters
If a machine operator who does not have liability insurance carries out repair welding on
forestry machinery in the forest, a certificate is not required. If the work is done by a professional
If you are welding in the forest, the welder will have a requirement for a certificate in their liability insurance.
If the work is done in the machinery company's garage/building, regardless of who does the work, then
a certificate may be required. A certificate is not required for hot work when the work is carried out on a
specially adapted workshop room that constitutes a separate fire cell. The workshop room must have
non-combustible surfaces.
It is recommended that machine operators who perform hot work on forestry machinery have a certificate in
hot works.

Sharpening skates
Sharpening skates is usually done with special machines with emery discs that produce sparks. This type of sharpening
is defined as hot work. If the grinding takes place in a non-industrial establishment, it is defined as
grinding is initially considered hot work that does not require a certificate. However, this must be clarified with
building owner if the insurance contract contains requirements for hot work. See point 2. in
Safety regulations for hot work.

Stone slabs
See tiles.

Roofers
Roofing using open flames, hot air or hot exhaust gases from a combustion process is
Work requiring a certificate.

Dental technicians
See gold and silversmiths.

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

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

Road maintenance
When maintaining road markings, open flames are 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, requirements are set for
certificate when performing hot work.

Vocational education – students and apprentices
There is no requirement for a certificate for students in vocational upper secondary school when performing heating
works when the work is done as part of the teaching under the supervision of a certified teacher. For
apprentice in a company, some insurance companies see it as a requirement for a certificate (in the same way
with foreign labor), while other companies will not require a certificate as long as the hot
the 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' classrooms for metalworking only are considered permanent,
specially adapted workshop space. Thus, there is no requirement for a certificate for the vocational school teacher.
If the teaching takes place in rooms that are used for more than just metalworking, also
woodworking, this is not to be considered a permanent, specially adapted workshop space. There are then requirements for
certificate for vocational school teacher
