Appeal to the people!
In order to avoid tragedies associated with gas appliances and equipment, Main Directorate of the Ministry of Emergency Situations of Russia for St. Petersburg appeals to all residents and guests of the city to observe elementary safety rules during their operation:
Gas cylinders and gas equipment should be purchased only from specialized organizations that have certificates for the sale of these products. After all, their owners are responsible for the safe operation of working gas appliances and their maintenance in proper condition. Never buy gas appliances, including gas cylinders, from unauthorized persons.
An annual inspection of gas equipment by specialists is mandatory.
Before opening the gas valve on the stove, bring a lit match to the burner.
Remember that gas mixed with air is explosive and flammable!
Sources of ignition of the mixture can be: open fire (matches, cigarettes, etc.), an electric spark that occurs when turning on and off electrical appliances. In order to avoid poisoning, it is necessary to check the draft before ignition, immediately after switching on gas appliances and during their operation, monitor the condition of the ventilation ducts, constantly ventilate the room, especially before going to bed.
It is advisable to place gas cylinders (working and spare) for household gas appliances outside buildings (in annexes, basement and basement floors, cabinets or under casings covering the upper part of the cylinders or a gearbox) at a blank wall at a distance of no closer than 5 meters from the entrances to the building. Outbuildings must be made of non-combustible materials.
Outbuildings and cabinets for gas cylinders must be locked to prevent access to them by children and unauthorized persons and have blinds for ventilation.
When using gas at home, it is prohibited:
Tie ropes to gas pipelines (this violates the density of threaded connections, gas leakage may occur and, as a result, an explosion); dry clothes and hair over a lit stove.
Arbitrarily reinstall and repair gas appliances, cylinders, fittings; leave unattended working gas appliances.
Allow children of preschool age and persons who do not know the rules for their safe use to use gas appliances.
Use an open flame to detect gas leaks (only soapy emulsion should be used for this).
Install pressure regulator without O-ring or gasket.
Bend and twist the rubber-fabric sleeve (hose), allow damage to the outer layer of the sleeve (cuts, cracks, kinks), as gas leaks occur in these places; place flammable materials and liquids near the operating stove; use rooms where gas appliances are installed for sleeping and relaxing; use gas and gas stoves for space heating.
Attach parts of gas fittings using a sparking tool; store spare cylinders.
In the event of a leak from an underground gas pipeline gas through loose soil or cracks in the foundation can penetrate into the basement of a residential building. Having discovered the smell of gas, it is necessary to protect the entrance to the basement, make sure that they do not smoke or light a fire nearby, ensure ventilation of the basement, entrance and call the emergency service.
In the event of a malfunction of the gas equipment or if there is a smell of gas, you should immediately stop using the device, turn off the taps on the stove and the valve on the cylinder or the flag on the gearbox, call the emergency service by calling "04" and thoroughly ventilate the room. During this time, do not use open fire, do not turn on or off electrical appliances and electric lighting.
Remember that you are responsible for the serviceability of the gas equipment inside the apartment. When selling any gas appliance must be supplied with an instruction manual. The person who installs the machine must give you a document certifying that the work has been carried out in accordance with technical standards and safety rules. Flexible hoses should be as short as possible (no more than 2 m). Make sure they are tight on the faucet. The maximum service life of the flexible hose is four years (the limit may be marked on the hose), but care must be taken to replace it every two years. The hose clamp should provide a complete seal, but do not try to clamp it too hard as this may rupture the hose and cause a gas leak. Do not forget that the gas used in everyday life is explosive, therefore, when using gas appliances, you must follow the fire safety rules!
Gas leak detection methods:
Approximately. Bubbles form on the surface of soapy water poured along gas pipes at leak points.
Aurally. In the event of a strong leak, the gas escapes with a whistle.
By smell. The characteristic odor that the gas emits becomes stronger near the leak. Never look for a gas leak with an open flame, such as a lit match. Try to cut off the gas supply if possible. Be sure to call the fire department.
When using gas appliances in the home the following security measures should be followed:
Constantly check the draft, keep the windows in the rooms where gas appliances are installed open. The burning gas burns oxygen, therefore, it is necessary that constant ventilation be provided in the room. Do not plug the ventilation openings in winter.
Do not leave working gas appliances unattended unless they have the appropriate automation and are not designed for continuous operation.
Do not use gas stoves for heating, and rooms where gas appliances are installed for sleeping and relaxing.
At the end of using gas, close the taps on gas appliances, the valves in front of them, and when using cylinders, the valves of the cylinders.
Regularly check the tightness of hoses and pipe fittings with soapy water.
Keep your gas stove clean.
When leaving the apartment, turn off the gas on the gas pipeline or turn on the valve on the gas cylinder.
Remember, usually gas leaks occur as a result of a breakdown of the hose connecting the gas pipeline to the stove, depressurization of threaded connections, forgetfulness of people leaving valves open, pranks of children, flooding the flame with water that has overflowed the edge of the dishes.
It is forbidden:
Allow preschool children, persons who do not control their actions and do not know the rules for using these devices to use gas appliances.
Store empty and filled with liquefied gases cylinders in rooms and basements. Have in a gasified room more than one cylinder with a capacity of 50 (55) l or two cylinders of 27 l (one of them is a spare).
Place cylinders against the furnace doors of furnaces at a distance of less than 2 meters from them.
Use gas in case of malfunction of gas appliances, lack of traction, detection of gas leaks, without checking the condition of smoke and ventilation ducts.
Any unauthorized actions with gas equipment, gasification without appropriate permits, and the involvement of random persons for the repair and rearrangement of gas appliances are prohibited. All types of work related to gas should be carried out only by specialized organizations.
The population using gas in everyday life is obliged to:
Be instructed in the safe use of gas in the operating organization of the gas facilities, have and follow the instructions for operating the devices.
Monitor the normal operation of gas appliances, chimneys and ventilation, check the draft before switching on and during operation of gas appliances with the removal of combustion products into the chimney.
Before using a gasified oven, check that the damper is fully open. Periodically clean the “pocket” of the chimney.
At the end of using gas, close the taps on gas appliances and in front of them, and when placing cylinders inside the kitchens, additionally close the valves near the cylinders.
In the event of a malfunction of the gas equipment, call the employees of the gas facilities.
In the event of a sudden cessation of gas supply, immediately close the valves of the burners of gas appliances and inform the gas service by calling "04".
Before entering basements and cellars, before turning on the light and lighting the fire, make sure that there is no smell of gas.
If you smell gas in the basement, entrance, courtyard, street: inform others about the precautions; report to the gas service by phone "04" from a non-gassed place; take measures to remove people from the gassed environment, prevent the switching on and off of electric lighting, the appearance of open flames and sparks; prior to the arrival of the emergency brigade, organize ventilation of the room.
Take care of yourself and your loved ones!

The operation of any equipment requires us to know elementary things and rules that make this operation safe for us and those around us. LPG equipment is no exception and also requires the owner to understand simple, but at the same time important rules.
Accidents with HBO are quite rare and, as a rule, most of them are associated with careless or improper operation, as well as neglect of safety regulations. Given this fact, I decided to talk about how to properly use a car with LPG in order to prevent an emergency and not become a victim of an accident through my own fault.
Basic rules for the operation of HBO on a car
2. Sun and gas. Avoid long periods of inactivity under the sun. Direct sunlight, especially if it falls on a gas cylinder, can cause the gas fuel to expand significantly and lead to an accidental release of gas or even an explosion.
