Below you will find the current legal framework covering the distribution of bottled liquid petroleum gas and the gas installations that use it.
- Regulation of the distribution of liquid petroleum gas (Real Decreto 1085/1992, 11 September) (in Spanish).
- Technical regulation of the distribution and use of gaseous fuels (R.D. 919/2006, 28 July) (in Spanish)

Safety Advice

If you notice a GAS LEAK:

  • Do not light any naked flame (matches, lighter) and don't smoke.
  • Do not turn on or off any lights or electrical appliances.
  • Close all gas taps.
  • Air the room by opening doors and windows.
  • Warn neighbours on lower floors.
  • Call DISA on 900 10 10 37 (24 H)

Advice to follow that may avoid situations of risk

Wherever there is a gas installation it is OBLIGATORY to have ventilation grill in place. Make sure that they are always free of obstacles and objects.
A lively blue flame indicates good and therefore economic, clean and safe combustion. A flame with red or yellow spots is a sign of poor combustion due to a poor regulator or dirt in the burners and blackens the bottom of pans and produces toxic carbon monoxide gas.
Keep an eye on pans on a cooking flame. Contents boiling over may extinguish the flame leading to a gas leak.
The installation of water heaters in bathrooms is FORBIDDEN. Water heaters installed inside residences must be connected to a conduct that extracts gases produced by combustion to outdoors.
Do not install a gas cylinder below floor level. Always place it in a vertical position.
If any anomaly or poor functioning of appliances or installation is observed, DO NOT try to repair it. Call a technician authorised by the manufacturer or a gas installation company.
Avoid leaving the hose in contact with the back of the oven in your kitchen, or with any hot element of the appliance.
Hoses should not be longer than 1.5m.

Indications in the case of ACCIDENTS

Direct contact with the product.

  • The product in either liquid or low pressure gas form can cause burns due to freezing.
  • The fumes are irritating.
  • Wash in abundant water for 15 minutes.
  • See your doctor if the irritation persists.
  • Wear safety goggles.
  • The liquid product can cause burns due to freezing.
  • Wash the affected area with water for 15 minutes, remove clothing if it hasn't stuck to the skin and see your doctor.
  • Wear clothing that is fire resistant and waterproof if possible. Wear safety gloves.
  • Fumes and mist are irritating to the respiratory tract.
  • In high concentrations, they have an anaesthetic effect and can produce nausea, headache and vomiting.
  • See your doctor.
  • The use of autonomous breathing equipment with positive pressure is recommended in the case of high concentrations of the product.
  • Not applicable.
  • Not applicable.

Physical and chemical hazards.


  • Extinguishing methods: Cover with dry chemical powder BC, carbonic anhydride; try to close off the fuel source.
  • Personal protective equipment: Fire protection suit. Mask or respiratory protective equipment with positive pressure.
  • General fire-fighting methods: Try to close off the fuel source If you can't put the fire out, allow the fuel to be consumed in a controlled manner, cooling the pans and elements exposed to the fire.
  • Fire extinguishing methods that must NOT be used: Water aimed at the fire.

Products that are a result of decomposition/combustion: Carbon dioxide and water

In case of accidental spillage

Personal protection: Avoid inhaling the fumes by placing your back to the wind on the opposite side to the leak. Don't smoke, remove all sources of ignition. Cut off the electricity supply if possible from a point that is distant from the spillage and avoid electrostatic charges.

Environmental protection: Avoid large leaks into the atmosphere; one litre of liquid butane releases 239 litres of gas. Danger of fire and explosion in the mixture released. Solar radiation generates oxidised by-products that are harmful to the atmosphere.

Cleaning methods:

  • Small spillages: Allow it to evaporate. Use water sprayed under pressure if possible.
  • Large spillages: Evacuate the area. Call the Civil Protection team, the Fire Brigade and the local Authority. Try to disperse with water sprayed under pressure.
