Natural gas is the cheapest type of fuel used in everyday life, but at the same time it is one of the most dangerous. How to use household gas appliances correctly and not replenish the sad statistics of the reports of the Ministry of Emergencies with careless actions – further in the material.
Requirements for the premises
Natural gas requires a large amount of air to burn, so the room in which the gas equipment is installed must be well ventilated. It must receive a sufficient amount of fresh air from the outside. In addition, during the operation of gas equipment, combustion products are formed and can accumulate in the room. The most dangerous of these is carbon monoxide (CO).
A carbon monoxide concentration of only 0.08% is already capable of causing headaches and suffocation. The content of 0.32% carbon monoxide in the air is dangerous for loss of consciousness and paralysis. Exceeding the threshold of 1% is deadly! Loss of consciousness and death occurs within a few minutes.
Make sure that the openings of the ventilation ducts are not covered or blocked by other objects.
Use forced ventilation devices such as kitchen hoods or exhaust fans.
Make it a rule to open a window or window while using the device.
To ensure natural air circulation inside the apartment, the kitchen door must be equipped with a ventilation grill or have a 4-5 cm gap in the lower part of the doorway for unhindered access of fresh air from other rooms, even when the door is closed to the kitchen.
Placement of gas equipment
The place of installation of gas appliances is determined by a project developed for each specific room. The document displays the installation location of each point of consumption of natural gas, metering device (gas meter), valves and gas mains located inside the room.
As a rule, the project gives a general layout of devices and valves without reference to specific dimensions, therefore, when installing gas appliances, you must strictly follow a few simple rules:
1. The distance from the edge of the hob to the edge of the vertical surface of furniture or a wall must be at least 100 mm.
The surfaces themselves adjacent to the gas stove (furniture, walls, etc.) must be made of a material that can withstand temperatures of 90 ° C for a long time.
For gas boilers and water heaters, the minimum distance is usually 40–150 mm. The exact value must be found in the installation instructions for the specific model of the device.
2. It is forbidden to install a gas stove in a niche formed by two vertical walls of furniture or a room. This will restrict air access to the burners and disrupt the normal heat removal from the stove surface.
The presence of a vertical surface is allowed only on one side of the gas stove.
3. Gas shutoff valves must be easily accessible. Nothing should prevent you from quickly stopping the gas supply to the device.
4. When using flexible gas supply hoses, make sure they do not touch the hot back wall of the stove. Destruction of the flexible hose entails the risk of unhindered and uncontrolled gas leakage! When you smell gas, immediately close the supply valve, call the emergency service at 104 from a mobile or 04 from a landline phone and ventilate the room.
It is strictly forbidden to use electrical appliances, matches, lighters and other devices that can provoke a spark!
5. The connection of the devices to the gas mains is carried out exclusively by the specialists of the gas supplying company. Self-connection is prohibited.
To ignite a gas burner, you just need to press the electric ignition button or the knob of the desired burner itself (if the oven or surface is equipped with automatic ignition) and turn it, the automation will do the rest. If the device is not equipped with an automatic ignition system, then the required burner is ignited with an ordinary match or a special lighter.
The main thing to remember is that you need to supply gas when the spark source is near the desired burner.
In appliances equipped with a burner flame control system ( gas control ), it is necessary to hold down the knob for several seconds, forcibly supplying gas to the burner. This time is required to heat up a special sensor that allows the gas to flow unhindered to the burner. If, for any reason, the fire goes out (the gas supply to the mains is cut off or the burner is flooded with liquid boiled out of the cookware), the sensor will cool down and cut off the gas supply.
As you can see, it is easy to light the gas, it is much more difficult to control the process. Important to remember! Gas is a source of open fire in your kitchen! To do this, you need to strictly follow a few simple rules:
Do not use the surface of the stove to store, even temporary, flammable items.
You always need to control the cooking process. It is unacceptable to leave the gas appliance unattended.
Do not use the drawer under the oven to store flammable items (kitchen towels, napkins, paper).
Pay particular attention to cooking with oil or fat. They can easily be overheated to a state of spontaneous combustion.
Never extinguish burning oil with water! If it catches fire, turn off the hotplate and cover the cookware with a lid or damp towel. Regular baking soda will also help to exclude the access of air to the fire site, which needs to be plentifully poured into the flame.
It is forbidden to place clotheslines and dry clothes over a gas stove.
Also, do not use pipes for the removal of combustion products from gas boilers, water heaters and the body of gas convectors for drying clothes. Use gas appliances only for their intended purpose! Heating rooms with a gas stove or hob is unacceptable.
Self-tuning and adjustment of gas equipment is not allowed. This work must be performed exclusively by qualified personnel of the natural gas supply company.
During a long absence, vacation or business trip, always close the gas supply valves to the devices.
Always check the color of the burner flame. Normal combustion of natural gas has a blue or slightly purple tint.
If there is a yellow or red color in the flames, it means that there is a high probability that the fuel does not burn completely, and the gas equipment of the device needs adjustment.
The basic rules for the safe operation of gas appliances are given in a short video.
Basic recommendations for using a gas stove
Below are some tips for operating a gas hob, following which will allow you to keep the original appearance of the stove and the utensils used for a long time:
1. Use pans with a suitable diameter. It is important to remember one thing here – under no circumstances should the flame touch the walls of the dishes
2. It is highly discouraged to heat empty dishes. From this, its bottom can be deformed.
3. Do not use pans with an uneven bottom. It is unstable and may tip over and extinguish the burner flame. If the device is not equipped with a gas control system, this is fraught with filling the room with gas.
4. Place cookware exactly in the center of the hotplate. Firstly, this way the heat will be evenly distributed, and, secondly, the likelihood of the dishes tipping onto the surface of the stove is excluded.
5. Do not place cookware directly on the hotplate without using the wire rack. The combustion process of gas from this can be disrupted.
6. Make sure that the burner burns evenly. If it burns unevenly, carefully adjust the position of the burner cover on the splitter.
7. Do not place too heavy dishes on the wire rack. With its weight, it can damage not only the grate, but also the surface of the stove.
The use of gas in everyday life is associated with many risks that arise, as they say, “out of the blue”, as a rule, from unwillingness to comply with elementary fire safety rules. However, once again we recall: common sense must be present in absolutely all actions related to the operation of gas appliances, from the banal reading of the instructions to the reasonable daily use of devices. There is no place for negligence! Everything should happen within the existing rules and restrictions. Only this approach will not allow a serious accident to develop and will not lead to irreparable consequences.
