Butane gas cylinders are often used in outdoor barbecues, gas stove cooking, lighter filling and other scenarios due to their portability and high combustion efficiency. However, butane gas is a flammable and explosive substance. If used improperly, it can easily cause leakage, explosion, fire and other dangers. Understanding the safety usage regulations of butane gas cylinders and taking comprehensive risk prevention measures throughout the entire process are the keys to avoiding accidents.

Prevention during the storage process is the foundation for safe use. Butane gas cylinders should be stored in a cool, well-ventilated and dry environment, away from open flames and high-temperature heat sources (such as heaters, stoves, and direct sunlight). The ambient temperature must not exceed 40℃ to prevent the cylinders from exploding due to a sudden increase in internal pressure caused by high temperatures. At the same time, when storing, it should be placed upright to avoid tilting or violent impact, so as to prevent damage to the bottle body and loosening of the valve, which may cause gas leakage. And it must not be stored together with oxidants (such as potassium permanganate) or corrosive substances (such as hydrochloric acid) to avoid chemical reactions that may cause danger. In addition, when storing at home or outdoors, the quantity should be controlled. Generally, no more than two bottles should be stored in a single use scenario, and they should be kept in an area out of reach of children and pets.

The norms during operation and use are directly related to safety. Before connecting the gas cylinder to appliances such as stoves and lighters, it is necessary to check whether the cylinder valve, connecting pipe and interface are damaged, aged or loose. If cracking of the connecting pipe or loss of the interface sealing gasket is found, the parts should be replaced in time. Do not force its use. When connecting, make sure the interfaces are aligned and tightened. You can apply soapy water to the interfaces and observe if there are any bubbles to detect any leakage. If leakage is detected, immediately close the gas cylinder valve and move to a well-ventilated area. It is strictly forbidden to switch on or off electrical appliances, make mobile phone calls or use open flames at the leakage site. During use, it is necessary to ensure good ventilation in the environment and avoid prolonged use in confined Spaces (such as small tents or closed kitchens) to prevent the concentration of butane gas from being too high and reaching the explosive limit. At the same time, do not use the gas cylinder upside down or horizontally to prevent liquid butane from directly flowing into the combustion device, which may cause abnormal flames, equipment damage or even explosion.

Emergency response measures are the key to dealing with sudden dangers. If gas cylinder leakage is found during use and cannot be controlled in time, or if a small fire occurs, personnel should be evacuated immediately, the gas cylinder valve should be closed (if it is safe to operate), and dry powder fire extinguishers and fire blankets should be used to cover and extinguish the fire. It is strictly forbidden to directly use water to put out butane fires (butane is insoluble in water and has a lower density than water. Using water to extinguish the fire will cause the fire to spread). In the event of a severe leakage or explosion of a gas cylinder, immediately move away from the scene, call 119 to report the incident, and inform the rescue personnel of the type, location and leakage situation of the gas cylinder. In addition, after use, the valve of the gas cylinder should be closed in time, the connection disconnected, and the gas cylinder properly stored. Do not discard or disassemble the gas cylinder at will. Discarded gas cylinders should be handed over to professional institutions for recycling and disposal.

In conclusion, the safe use of butane gas cylinders should run through the entire process of "storage - operation - emergency response". Users must strictly abide by the regulations and always remain vigilant to effectively prevent dangers and ensure safe use.
