[Haichuan Chemical Safety News] A major fire broke out in a warehouse at a chemical plant in Changzhou on 20170728

Safety work is indeed not easy; every aspect must be taken into account, with no room for any negligence.

Prevent fires before they occur; safety first.

There are many warehouse fires in the summer, mainly due to electricity use, the evaporation of flammable substances, and factors such as temperature reduction

Let’s analyze together: what are the key points for fire prevention in summer?

There is thick smoke; it’s not known whether it is poisonous.

The summer climate is hot, with frequent thunderstorms and high humidity, making it a period with a high incidence of various fire accidents. Therefore, in light of the characteristics of summer fires, we must focus in our daily lives and work on preventing high temperatures, spontaneous combustion, explosions, electrical fires, and lightning strikes, in order to avoid all types of fire accidents and effectively safeguard the safety of production facilities as well as the lives and property of employees and their families. Here are some fire prevention tips for summer for your reference. I. Characteristics of summer fires 1. High temperatures and heat make fires more likely to occur. With the arrival of hot weather, there is a significant increase in the use of electrical devices such as air conditioners, refrigerators, and electric fans. This leads to overloading of the electrical wiring; damaged insulation can cause short circuits and sparks. Additionally, water getting into the motors of these appliances can reduce their insulation strength, resulting in short circuits that burn out the motors and cause fires. There is also the issue of production equipment heating up as a result. Summer is also a period when car fires occur frequently. Moreover, in hot weather conditions, the slightest carelessness during the production, transportation, and storage of chemical hazards can lead to fires. 2. High temperatures lead to rapid spread, making it easy for fires to develop on a large scale or in three dimensions. Hot weather tends to create intense convective weather, accelerating the spread of fires. In summer, there are long daylight hours, high temperatures, little precipitation and high evaporation, resulting in dry conditions. This lowers the ignition point, making it easy for fires to start when exposed to an open flame. Under the influence of radiant heat, the fire can spread to adjacent buildings, leading to multi-level or large-scale fires. 3. Lightning-induced fires are likely to occur. During the hot seasons, thunderstorms become more frequent, and the intense lightning generated by thunderstorms can easily cause fires in buildings, flammable gases, forests, and other areas. 4. It is difficult to extinguish, and it can easily cause casualties. In hot weather, rescued people tend to become irritable, and in the absence of timely assistance, they may resort to actions such as jumping from buildings, resulting in casualties. II. Precautions for fire safety at work 1. Rags used for maintenance or cleaning, as well as flammable materials, should be collected and disposed of promptly; leaving them in high-temperature environments can easily lead to fires. 2. Items with high risk must be stored in accordance with safety regulations, and regular inspections and cleaning should be carried out to eliminate sources of fire, as well as proper ventilation should be ensured as required. 3. Aging wires and cables, as well as machinery that may cause fires or explosions, should be subject to regular safety inspections. Equipment that needs to be replaced must be replaced without delay; one should not risk larger problems by ignoring minor issues. Flammable materials should be kept away from wires and cables. 4. Strengthen the safety management of fire protection facilities, improve the systems for their maintenance and regular inspections, to ensure that they remain in good condition. 5. Conduct timely special summer fire safety inspections of office areas, equipment areas, and item storage areas. 6. Strictly implement the safety management procedures for hot work. 7. Thunderstorms are frequent in summer; regular inspections of lightning protection measures should be carried out to ensure that the grounding and bonding facilities for major hazard sources, equipment, and buildings are in good condition, thereby effectively preventing the effects of lightning. III. Fire prevention precautions outside of work (I) Home fire prevention measures 1. Teach children not to play with fire or electrical equipment. 2. Do not litter cigarette butts, and do not smoke in bed. 3. Do not connect wires randomly; never use copper or iron wires as substitutes for circuit fuses. 4. Do not leave the area unattended when using an open flame for lighting; do not use an open flame to look for items. 5. Before leaving home or going to bed, check that electrical appliances are turned off, gas valves are closed, and any open flames are extinguished. 6. In the event of a gas leak, quickly close the gas supply valve, open doors and windows for ventilation. Do not touch any electrical switches or use open flames, and promptly notify a professional repair service to handle the situation. 7. Liquefied residue cannot be discarded arbitrarily. 8. Flammable and explosive items such as gasoline, alcohol, and nail polish should not be kept at home in quantities exceeding 0.5 liters. 9. Never pile up miscellaneous items in corridors, at stairwells, etc.; ensure that passages and safety exits remain unobstructed. 10. All chargers should not be used for long periods of time, nor should they continue to operate even when no one is around. 11. Study fire safety knowledge carefully, learn how to use fire extinguishers, and understand the methods for self-rescue and rescuing others in case of a fire. (II) Common sense for fire prevention in summer 1. Choose decoration materials carefully, and keep painting work away from sources of fire. For interior decoration, use materials that are difficult to ignite or non-flammable, and arrange electrical wiring properly. When painting, doors and windows should be opened promptly to allow flammable gases to dissipate; smoking or using fire inside the room where painting is taking place is not allowed. Exposed power wires should be wrapped with insulating tape to prevent leakage or short circuits. 2. Fire extinguishing equipment is a valuable asset, and it is essential for motor vehicles. Car fires usually result from short circuits in the wires inside the vehicle or from oil leaks, with short circuits being caused mostly by human error. For example, the wiring harnesses inside the vehicle are exposed to high temperatures for extended periods of time; coupled with the rising temperatures in summer, this accelerates the aging, hardening, and deterioration of the insulation surrounding the wires, resulting in exposed wires that can easily cause short circuits. In addition, aging fuel intake hoses in cars, aging wiring harnesses of electric gasoline pumps, and faulty relays can also easily cause a car to catch fire on its own. During the scorching summer months, motor vehicles are under heavy load for extended periods, resulting in severe engine contamination. Coupled with high temperatures and harsh weather conditions, as well as inadequate ventilation systems, spontaneous fires occur frequently. Therefore, it is necessary to pay attention to the proper maintenance and repair of vehicles, equip them with dedicated vehicle fire extinguishers, and avoid placing on the dashboard items such as gas lighters, air fresheners, and insecticides that can expand when heated and thus cause explosions and fires. 3. Don’t panic if an electrical appliance catches fire; cut off the power supply first before attempting to extinguish the fire. Electricity consumption increases significantly during summer, and if household appliances such as televisions or induction cookers catch fire, never pour water on them. Instead, turn off the power supply first, then use a dry powder fire extinguisher or a carbon dioxide fire extinguisher to put out the fire. In emergency situations, you can also cover the appliance with wet blankets or similar items to smother the fire. 4. Wiring must be installed safely; improper wiring can lead to problems. There are many types of electrical circuits, and their installation is complex; no one should connect wires casually. If line maintenance or modification is required, it should be carried out by a professionally qualified electrician. When laying electrical wiring, the wires must be protected by fire-resistant tubes, and any exposed ends must be wrapped with insulating tape to prevent fires.
