Flammable goods

Flammable and explosive goods is a collective term for flammable gases, flammable liquids and other fire reactive goods. Handling of these are associated with particular risks and are regulated by the act 2010:1011 and regulation 2010:1075 on flammable and explosive goods.

Flammable liquids are liquids which have a flash point (the lowest temperature of a liquid when it is emitting steam in an amount such that an ignitable mixture with air is formed) of 100 ° C or lower. Flammable gases are gases which at a temperature of 20 ˚C are able to form a flammable gas mixture with air.

Handling larger quantities of flammables requires permission from the city management (kommunen) and permit holders of Karolinska Institutet's permit is the Vice-Chancellor. The permit is time-limited and conditional. Periodic inpections are done by the fire department to ensure that KI follow the conditions stated in the permit, as well as laws and regulations within the field.

For example, KI is obligated to have a well-structured organization with qualified "Supervisors for flammable goods" and "Flammable goods monitors". All departments have to make sure that flammable goods are handled and stored in a safe manner and that the amount of flammable goods doesn't exceed the stated limits per fire cell. Important is to register all flammable goods in KLARA product database with the record "max storage" (more information under Chemical safety and KLARA product database).

A fire cell is a part of a building, such as rooms or floors that are technically constructed so that a possible fire is prevented from spreading to another part of the building during a given time.

Flammable products are stored in fireproof ventilated cabinets. During working hours, only amounts used should be taken out from the storage.

Storage requirements at KI campus

  • Flammable gas - Is stored in ventilated EI 90 classified cabinet/storage.
  • Flammable liquid - Is stored in ventilated EI 60 or EI 90 classified cabinet/storage.

Storage requirements at hospital area

  • Flammable gas - Is stored in ventilated EI 90 classified cabinet/storage.
  • Flammable liquid - Is stored in ventilated EI 90 classified cabinet/storage.

Fridges and freezers

It is not allowed to store flammable goods in ordinary fridges and frezzers, only specific "non-sparking" lab freezers and fridges shall be used. These refrigerators and freezers should be labelled to indicate that thay contain flammable goods.

Labelling and signs

Flammable products should be labelled with symbols and warnings so that users are informed of the dangers. Labelling is determined by the classification of the product. Cabinets and storage, as well as doors leading to spaces where flammable goods are stored, should be well labelled to inform everyone where flammable good are kept.

Classification of explosive areas

In premises, or part of premises, where open handling of flammable goods may cause an explosive atmosphere, an area classification plan should be drawn. Classified areas must be well marked and only special EX-classified electrical equipment is allowed to be used in such an area. To avoid explosive environments to arise it is preferable to handle flammable goods in closed systems or in ventilated areas (fume hood, benches etc).
