Fire Safety Advice

While DEX is responsible for ensuring your buildings are safe and meet all fire regulations there are also many precautions Property Guardians can follow to help minimise the risk of fire.

The following tips are important for optimising safety:

  • Leave smoke detectors in the room where you sleep, when they have been installed.
  • Make sure you are aware of the escape routes on your premises.
  • Make sure escape routes are never blocked by cupboards, junk, bicycles or waste, etc. Be strict with each other in enforcing the rules.
  • If you think you smell gas, avoid flames and do not use electricity. The tiniest spark can cause an explosion. Notify the gas company and even the fire brigade if necessary. Open all the windows and turn off the gas at the mains. Never repair a gas leak yourself, call in a recognised gas installer.
  • Make sure that you keep your mobile phone handy during the night and always keep your keys in the same place.

These tips help minimise the risk of fire:

  • Don’t use aerosols near a fire or heat source.
  • Don’t use gas, water or electricity pipes or cables to hang things on. These pipes and cables may become very hot and there is a risk of breakage.
  • Make sure there is sufficient distance between cooking appliances and flammable materials.
  • Don’t use faulty electrical appliances.
  • Turn off the TV when you are not using it. Don’t leave it on standby.
  • Never leave electrical appliances such as irons, toaster, hairdryers, curling irons etc. unattended when you are using them.
  • Make sure the ventilation grills of micro-wave and electrical ovens are not blocked.
  • Always call in a recognised installer for repairs to electrical cables or gas pipes.
  • Only use oil-filled radiators, do not use electric heaters. Always ensure there is sufficient free space around them and that they are turned off when you are not it.
  • Unplug your TV, computer and audio equipment when there are severe thunderstorms.

Gas Safety Advice

If you think you have a gas leak or can smell gas, leave the house and phone the National Gas Emergencies number immediately on 0800 111 999.

If you’re at home, and you can do it safely, turn off your gas supply. The gas mains tap should be beside your gas meter. Move the handle a quarter turn until it’s at 90 degrees from the pipe to shut off the gas supply.
What to do if you smell gas


  • Open doors and windows to allow fresh air in.
  • Turn off the gas at the mains tap, which is usually near the meter. Move the handle a quarter turn until it’s at 90 degrees from the pipe to shut off the gas supply.
  • Leave the property.
  • Phone the National Gas Emergencies number on 0800 111 999. Only use a mobile phone from outside the property. The number is free and available 24 hours a day.
  • Follow the advice given by the emergency adviser.
  • Wait outside for a gas engineer to arrive.
  • If you are feeling unwell, visit your GP or hospital immediately. Tell them you may have been exposed to a gas leak or carbon monoxide poisoning.


  • Smoke, light a match or use any other naked flame.
  • Turn any electrical switches on or off.
  • Use doorbells, mobile phones or any other electrical switches which could cause a spark.
