Be prepared

• Study, become familiar with and carry out the Seveso Site-specific self-protection Instructions posted on the website of the corresponding Region.
• After reading these instructions, discuss the matter with everyone in your family.
• Gather the following items or make sure it is easy to gather them fast in one room:
  • Adhesive insulating tape (paper tape), to seal the door and window frame gaps (in case of a toxic cloud).
  • Scissors.
  • Plastic sheets (cut-down to size) or plastic garbage bags to cover the openings of the air-conditioning units.
  • Towels and small cloths.
  • Flashlight with batteries (the batteries should be stored next to the flashlight, otherwise they should be regularly checked), for the event of a power failure.
  • First aid kit.
  • Necessary medicines for anyone in the family.
  • Other supplies that may be specifically required.
• Select the room of your home that offers maximum protection. Take into consideration that the room should:
• Be at the centre of your home.
• Have the minimum number of windows and doors, which should shut tightly.
• Communicate with the main bathroom or half-bathroom.
• Not have its windows on the danger side (establishment or street).
• Not have any openings for air exchange with the environment (i.e. fireplace, air-conditioning units, ventilation openings etc.).
• Be on the highest floor possible (most toxic gases, as they are heavier than air, move towards the lower air layers).
• Check the preselected room for leaks (if there is any air ingress) on a windy day. Permanently seal the window openings with duct tape, so the room offers a high level of protection.
• Drive cautiously around industrial establishments or vehicles transporting dangerous materials.

• Remain calm and try to calm those next to you.
• Stay or immediately move to a safe, enclosed space, and avoid movement on the streets. The aim is to protect yourself from dangerous chemicals that may enter your home, from potential explosions (primary and secondary fragments) and from thermal radiation.
• Shut any doors (inside and outside) and windows tightly. Shut down any ventilators and air-conditioning units.
• Prepare wet towels to protect yourself in the event of exposure to inhalation irritants.
• Extinguish any flames, turn-off the gas stove and do not smoke.
• In any event, watch the media and stay connected on social media. Trust only official announcements and only follow the instructions of the competent Authorities.
• In the event of an accident at a SEVESO-site, follow the Specific Self-protection Instructions, posted on the website of the corresponding Region.
• Wait for the competent Authorities to provide information regarding the use of tap water or drink only bottled water.
• Do not go to the scene of the accident.
• Avoid calling the Authorities or friends and relatives on the phone, unless you need immediate assistance. Unnecessary phone use keeps lines busy and prevents use in an emergency.
• Do not expose yourself or others to dangers.
• If you are inside a building away from your home, implement the emergency plan of that building.

• Shut tightly any windows, window shutters and curtains, as well as the outside and inside doors of your home, without locking them.
• Do not go near the windows for any reason. There is a risk of injury from broken glass.
• Extinguish any flames, turn off the air-conditioning, whether part of a central system or not, and also turn off the ventilation systems, kitchen extractor, fans and any heating/cooling system.
• If you suspect a leak of flammable gases, turn off the main electrical power and natural gas switches, to prevent a potential explosion.
• Cover the air-conditioning units with plastic garbage bags.
• Do not use gas cylinders.
• Do not smoke.
• Bring your pets inside your home.
• Seal any door and window frame gaps (on all four sides) with adhesive insulating tape (paper tape) or any other available means. In addition or alternatively, you can use wet towels or blankets, plastic sheets, aluminium foil or wax paper (baking paper).
• Cover the keyhole and door handle with paper tape.
• Using paper tape and plastic sheets, tightly seal the fireplace vents, the kitchen fan, all heating systems, air inlets and ventilation systems, and all doors and windows. In addition or alternatively, you can use wet towels or blankets, aluminium foil or wax paper (baking paper).
• Do not use the elevator (it acts as a pump, drawing air to the inside of the building).
• Go to your preselected room.
• If, despite your efforts, dangerous gases enter the building, fold a wet towel or cloth several times over, cover your mouth and nose, and take short breaths in order to filter the air you are inhaling. Alternatively, use the shower.
• Let your neighbours know about the danger.
• Watch the media and stay connected on social media. Trust only official announcements and only follow the instructions of the competent Authorities.

Dangers from staying at home

• In the event of an industrial accident where toxic gases are released, shutting all doors (inside and outside) achieves a high degree of protection, provided that the chemically polluted air is kept out of the home. Any polluted air entering the home can have very serious consequences on human health. Given that for many chemicals the lethal dose is extremely low, it follows that even brief exposure to a chemical substance can cause irreparable health damage. Therefore, it is extremely important to properly seal off any door and window frame gaps. Moreover, all of the above must be done as soon as possible, without letting valuable time go to waste.
• However, as soon as the danger is over, it is just as important to quickly and properly air your home, to clear it from all the air that was polluted with toxic substances.

• Close your windows and keep them shut, turn off the air-conditioning and ventilation system and close any air vents. This way, you get some short-term protection.
• In case you can leave the area, stay inside your car and drive carefully.
• In case you cannot leave the area and there is a safe building nearby, park your car at a spot where it does not obstruct traffic and enter the building. If there is no safe building nearby, remain calm and stay in your car.
• Watch the media and stay connected on social media. Trust only official announcements and only follow the instructions of the competent Authorities.

• Leave the accident site as soon as possible.

If you are…

• Down-wind of the accident (area B in the following drawing), leave moving vertically to the wind direction or water flow.
• Up-wind of the accident (area A in the following drawing), leave moving against the wind direction or water flow.
• As a general rule, move to higher ground, since many toxic substances are heavier than air.
• Do not walk on and do not unnecessarily touch surfaces where the leaked substance is on.

• Do not smoke.
• Cover up your body as much as possible.
• Filter the air you are breathing from dangerous gasses, dust or droplets, by covering your mouth and nose with a folded towel or cloth or a mask, and taking short breaths.
• Watch the media and stay connected on social media. Trust only official announcements and only follow the instructions of the competent Authorities.

• Call the Fire Service at 199.
• Give precise details (location, distance from the accident site, name, contact number, etc.) and describe the incident.
• Note:
• If there are any victims and make an estimate as to the number of people involved (number of fatalities, injuries) and the symptoms they have (e.g. dizziness, headache, eye irritation etc.)
• The colour of the smoke or leaking liquid.
• The smells and strange noises, if there are any.
• The behaviour of the cloud, if there is one (direction of movement, downwards or upwards, etc.) or the behaviour of the liquid.
• If there is any information/markings on the packaging, containers (barrels, cans and pallets) or tanker vehicle (company name etc.) (in the case of an accident involving a tanker vehicle).

• If there are any orange-colour signs (warning signs identifying the shipment materials), note the two numbers (one two/three-digit and one four-digit number), the so-called UN numbers, e.g.
   
• Do not go off the phone unless told so by the operator – they may require additional information.

• If there are any diamond-shaped hazards labels with colours (red, yellow, blue, etc.), illustrations (bomb explosion, black or white flame, skull and bones, etc.) and numbers on the bottom corner (1.1., 3, 4 etc.). See below examples:
• What is near the accident site (facilities, buildings, schools, day-care centres, senior citizen centre, mass transport stop/station, squares, rivers, lakes, drains, etc.).

• Properly air all rooms.

  -    For the next 1-2 days, leave your shoes outside when entering your home.

  -    Clean all the home furnishings and fixtures (doors, windows, rugs, floors), as well as the outdoor areas (balconies, stairs, terraces).

  -    Take daily showers, thoroughly washing your hands, hair and facial hair.

  -    Do not eat local fruits and vegetables. Instead, opt for packaged foods from other areas.

  -    Once the competent Authorities inform you it is safe to eat local fruits and vegetables, do so following their instructions (e.g. wash well before eating).

  -    The competent Authorities, if necessary, will also issue a free-range farming prohibition to animal farmers.

  -    Moreover, the competent Authorities will inform you regarding the suitability of consuming animal and fishing products.

  -    Wait for the competent Authorities to provide information regarding the use of tap water.

  -    Wait for the competent Authorities to provide information regarding the suitability of the local beaches for swimming.

  -    Make sure small children are not putting objects that may have been polluted by toxic substances in their mouths.

  -    Report the presence of vapours or other dangerous substances to your local Fire Service.

• Only follow the instructions of the competent Authorities.
• Act quickly if you have come into contact with or have been exposed to dangerous substances.
• Immediately seek medical assistance if you are experiencing unusual symptoms.
• In the event you have not left the area you were at, stay there until the competent Authorities instruct you to return to your home.
• After being informed that the accident has ended and it is safe to return to your home:
