Attention gas supply and operating organizations!

We draw the attention of gas supply and operating organizations to the need to take additional measures at gas distribution system and gas consumption facilities under conditions of extremely low temperatures.

At extremely low temperatures, gas supply and operating organizations (using measuring instruments, automation and signaling systems, telemechanics tools, and automated process control systems) must monitor, including, the air temperature in the premises of the GRP, SRP, and GRU.

The main safety measures for gas consumption facilities during severe frosts include checking the operability of safety automation, emergency alarm systems, regular inspection of equipment for icing, ensuring the operability of pressure regulators, and prohibiting the use of open flames for thawing gas pipelines and cylinders.

^{ABOUT THE OPERATION OF ELECTRIC HEATING DEVICES IN CONTROL CABINS!!!} 

In order to prevent incidents (fires) related to the operation of electric heating devices in the control cabins of lifting cranes operating outdoors (hereinafter referred to as the heating device), it is necessary to ensure the operation of heating devices in accordance with the requirements of the operating manual for the lifting crane (hereinafter referred to as the operating manual) and to take the following measures.

Conduct a check of the functionality of heating devices, including the correctness of their connection and the operability of protective disconnection devices.

Exclude the use of heating devices not provided for in the operating manual.

When operating heating appliances, follow these requirements:

Heating devices must be connected to the electrical network after the input device and must not be disconnected when the mechanisms of the lifting crane are turned off (paragraph 155 of the Rules for Ensuring Industrial Safety of Lifting Cranes, approved by the resolution of the Ministry of Emergency Situations of the Republic of Belarus dated 22.12.2018 No. 66);

before starting the operation of the lifting crane, inspect the heating device for any damage;

at the end of the operation of the crane, it is necessary to turn off the heating device using the switch in the control cabin (to prevent its automatic activation when voltage is supplied from the input device);

it is necessary to exclude the presence of foreign objects near (on) the heating device that may ignite;

ensure the availability of primary fire extinguishing means

in the cabin of the lifting crane.

Include these requirements in the safety work instructions for crane operators.

Recommendations for the safe operation of heating equipment during periods of sharp temperature fluctuations

The heating season is always accompanied by increased attention to safety, but periods when the weather behaves unpredictably — alternating between severe frosts and thaws — require a particularly careful approach. Sharp temperature fluctuations create unique challenges for heating systems, increasing the risks of breakdowns, carbon monoxide poisoning, and fires. Understanding these risks and strictly adhering to operating rules is the key to your safety and the longevity of your equipment.

Why are temperature swings so dangerous for heating systems? Unstable weather affects heating equipment much more than stable frosts or moderate warmth. Here are the main reasons:

Thermal stresses and material fatigue:

The essence of the problem: Metals and other materials that make up heating equipment (boilers, radiators, pipes, chimneys) constantly expand when heated and contract when cooled. The sharper and more frequent these "heating-cooling" cycles occur, the greater the thermal stresses.

Consequences:Over time, this leads to metal "fatigue," the appearance of microcracks in welds and joints, and deformation of elements. In critical cases, this can cause leaks of the heat carrier, gas, or even the destruction of parts of the equipment, such as the boiler heat exchanger or radiator sections. Old systems and cast iron boilers are particularly vulnerable.

Condensate and enhanced corrosion:

The essence of the problem: When warm and humid air from the room or combustion products in the chimney come into contact with cold surfaces (for example, the walls of the chimney, the inner surface of the boiler after a sharp drop in temperature), condensate forms. During thaws, when the outdoor temperature is higher and the chimney has not yet warmed up, this process intensifies.

Consequences: Condensate, especially from combustion products (wood, coal), often has an aggressive acidic composition. It destroys the walls of the chimney, leads to the formation of rust and corrosion of the metal parts of the boiler, which shortens the service life of the equipment and can lead to burn-throughs and leaks. In chimneys, condensate can freeze, blocking the exit of combustion products.

Inefficient combustion and increased soot formation:

The essence of the problem:With sharp changes in the outdoor air temperature (especially when transitioning from severe frosts to positive temperatures), the draft in the chimney changes. With weak draft, as well as when using wet fuel or overly strong closure of the dampers, the combustion process becomes incomplete.

Consequences:Incomplete combustion leads to the formation of a large amount of soot and creosote. These deposits accumulate in chimneys and on heat exchange surfaces, reducing heating efficiency (increasing fuel consumption) and, much more dangerously, increasing the risk of soot ignition in the chimney.

Overloading of equipment and automation:

The essence of the problem:During a sharp drop in temperature, users instinctively try to heat the room as quickly as possible by setting the boilers to maximum operating modes or actively lighting the stoves.

Consequences: Such intensive operation at the limit of capabilities can lead to overheating, wear of components, failure of automation, as well as provoke emergency situations if the equipment has not been properly maintained.

To effectively counter these threats, a comprehensive approach is necessary:

Professional and regular technical maintenance (TM)

This is not just a recommendation, but a necessity of life. The maintenance must be carried out:

Before each heating season:Comprehensive diagnostics of all systems.

In the middle of the season (for intensively used systems):Additional verification and cleaning.

In case of any suspicion of malfunction:Immediate appeal to specialists.

What is minimally included in maintenance:

Inspection (diagnostics) of the boiler:

Gas boilers:Checking the tightness of the gas pipeline and connections (with soapy water or a gas analyzer), the condition of burners, cleaning the heat exchanger from scale and soot, checking the operation of safety automation (draft, overheating, flame, pressure sensors), adjusting combustion parameters.

Liquid fuel boilers (diesel, waste oil): Checking the tightness of the fuel line and connections, checking and cleaning the burner device, cleaning the heat exchanger from scale and soot, checking the operation of safety automation (draft, overheating, flame, pressure sensors), adjusting combustion parameters.

Solid fuel boilers/stoves:Cleaning of the furnace, ash pan, grates, flues, checking the tightness of the furnace door and dampers, condition of refractory elements.

Inspection and cleaning of the chimney:

Definitely!Professional chimney cleaning from soot, creosote, and foreign objects. Insufficient draft is a direct threat of carbon monoxide poisoning.

Leak testing:Inspection of the chimney for cracks, damage, and areas of condensate leakage that may lead to carbon monoxide leakage into the room or ignition of adjacent structures.

Heating system check:

Pressure:Pressure control in the system, checking the expansion tank.

Air traffic jams:Removing air from radiators (using Mayevsky valves) to ensure even heating and prevent hydraulic shocks.

Condition of pipes and radiators:Inspection for corrosion, leaks, and the reliability of fastenings.

2. Adequate ventilation and carbon monoxide control

Carbon monoxide (CO) is a sneaky killer: it has no color, smell, or taste. The cause of its formation is the incomplete combustion of fuel, often caused by insufficient draft or air supply.

Supply ventilation:Make sure that the room where the heating equipment is installed has sufficient fresh air intake. It is not allowed to seal all gaps and ventilation grilles tightly, especially in frosty weather.

Regular ventilation:Ventilate the living spaces, especially before sleep.

Carbon monoxide detectors: This is your insurance. Install certified CO detectors near heating appliances and in sleeping areas. Regularly check their functionality (with the "test" button). They will sound an alarm long before CO levels become life-threatening.

3. Strict adherence to fuel usage recommendations for solid fuel boilers/stoves. 

Use only dry, clean fuel (firewood, coal, pellets) that corresponds to the type of your equipment. Wet firewood not only reduces efficiency but also actively produces soot and creosote, as well as leads to the formation of caustic condensate.

4. Comprehensive Fire Safety

Fire is one of the most destructive consequences of improper operation.

Ensure safe distances:Strictly follow the manufacturer's instructions regarding the minimum distances from heating equipment to combustible structures (walls, furniture). This is especially important for stoves and fireplaces.

Fire protection: Wooden walls or partitions near stoves and chimneys must be reliably protected with non-combustible materials (asbestos cardboard, basalt wool, brick masonry, metal sheets on a non-combustible base).

Preliminary sheet:In front of the fireplace or stove door, a metal sheet measuring at least 50x70 cm must be nailed or laid down to protect the floor from falling embers.

Do not dry the clothes!It is categorically prohibited to dry laundry, clothing, footwear, and other flammable materials on boilers, stoves, radiators, or near them.

Proper electrical wiring:Check the condition of the electrical wiring, especially if circulation pumps, fans, and automation are connected to heating appliances. Do not overload the network.

Firefighting equipment:Always keep a powder or carbon dioxide fire extinguisher, a bucket of sand, or a thick blanket (a rug) available for extinguishing small fires.

5. Attention and knowledge of malfunction signs

Be vigilant. Your attentiveness can prevent a tragedy:

Unusual smells: The smell of gas, burning, smoke, burnt insulation – this is a reason for immediate action. Turn off the gas, ventilate the room, call specialists.

Change of flame color:In gas boilers, the flame should be blue. Yellow or orange flame may indicate incomplete combustion or air supply issues.

Unusual sounds:Hissing, rumbling, knocking, cracking, clicking – may indicate leaks, pump malfunctions, deposits in the system, or other breakdowns.

Appearance of smoke or soot in the room:Immediately turn off the equipment, open the windows! This is a sure sign of poor draft and a risk of carbon monoxide poisoning.

Uneven heating of radiators:May indicate air bubbles, clogs, or circulation issues.

Pressure drop in the system:Sign of coolant leakage.

Failures in automation operation:Frequent boiler shutdowns, inability to start.

What to do when a malfunction is detected:

1. Turn off the equipment:Disconnect the boiler from the power supply, shut off the gas/fuel supply.

2.Ventilate the room:Open all windows and doors, create a draft.

3.Leave the danger zone: Remove people and animals from the premises.

4.Call specialists:

In case of gas smell: 104 (gas service).

In case of fire or heavy smoke:101 (fire service).

In case of other malfunctions:Service center servicing your system.

5.Under no circumstances attempt to repair complex equipment on your own,if you do not have the appropriate permissions and qualifications. This may lead to even more serious consequences.

The safety of heating equipment in unstable weather conditions is not a luxury, but a necessity. A thoughtful approach to operation, regular professional maintenance, and knowledge of basic rules will help you not only maintain warmth and comfort in your home but, most importantly, protect the life and health of your loved ones. Remember that investments in safety always pay off.
