Improper storage of chemicals in summer is prone to fire. What measures should we take

Hot weather poses a great threat to the safe storage of dangerous chemicals. Dangerous chemical fires also occur during the hot summer months. Temperature increases increase the volume pressure of hazardous chemicals. Expansion by heat and contraction by cold are general physical phenomena of objects. The expansion coefficient of flammable liquid is generally large, stored in closed container, the volume is easy to expand when heated, and the vapor pressure increases, making the pressure inside the container increase. If the pressure in the container exceeds the pressure that the container can bear, it will cause container failure, or even burst. What measures should we take to prevent it?
1. Qualified hazardous chemicals warehouse. Dangerous chemical warehouse should use refractory materials that do not conduct heat to do the heat insulation layer of roof and wall, eaves should be appropriately lengthened, in order to prevent sunlight into the warehouse; Warehouse walls shall be appropriately thickened with double doors and double roofs. Window glass is painted blue or frosted.
2. There should be lightning protection facilities. Hazardous chemicals warehouses are usually located in the unit or the edge of the city, and other buildings around to maintain a certain distance, so that the warehouse around the formation of an open area, the warehouse is vulnerable to lightning. Therefore, the warehouse should be installed lightning protection device, in order to prevent the fire accident caused by lightning.
Strictly control the temperature. Water storage roof or cooling water pipe shall be installed on the warehouse roof. When the temperature in the warehouse is above 30 degrees Celsius, spray water to cool down, so as to keep the temperature below 28 degrees Celsius. The warehouse roof, exterior walls and window glass can also be painted white to reduce the absorption of radiant heat. According to the nature and packaging of the goods, you can also pour well water and put ice cubes on the ground of the warehouse. If possible, you can install air conditioning to cool down. Some warehouses can open Windows in the morning and evening ventilation, into the cold air, closed doors and Windows at noon, to prevent hot air into.
4. Strengthen personnel management. Personnel in charge of hazardous chemicals warehouse shall hold a certificate. Warehouse management personnel to regularly inspect the warehouse, found that the problem is solved in a timely manner, to ensure safety.
5. Indoor installation of NB smoke can be the first time mobile phone received fire site, should take measures.
Attention should be paid to the place of operation and use
Business premises. For example, it is strictly prohibited to change the business types and reserves of dangerous goods without authorization in refueling and gas filling stations and LPG filling stations. Supervisors and business personnel must be trained and hold certificates before taking up their posts; There must be a sound safety management system, such as destruction system, purchase and sales system, storage and storage system; Warning signs such as "no open flame" shall be set up in prominent places of retail premises.
Place of use. Such as scientific research, teaching, medical and other industrial units, must have passed the fire training and assessment of qualified personnel management; Conduct regular inspection on the devices for electrostatic conductivity removal, air exhaust and pressure relief to ensure that they are in good condition and effective; Temporary storage places for dangerous goods should meet the requirements of fire control technical standards; The daily usage of the site shall not exceed the prescribed scope; To carry out regular checks to prevent leakage, facilities and equipment must be fully equipped, and ensure that the completion of effective.
