As the continuous high temperature increases the threat to the safe storage of hazardous chemicals, Wuxi Nanquan Pressure Vessel Co., Ltd. strengthens safety protection and does a good job in preventing heat and cooling to prevent fire and explosion accidents! Why is the risk high in high temperature? 1. The temperature rises to increase the volume pressure of hazardous chemicals Thermal expansion and contraction is a general physical phenomenon of objects. If the pressure inside a container increases beyond the limit that the container can withstand, it will cause the container to fail or even blow up. If the container is open, the liquid expansion beyond its capacity will spill over and run, bubble, drip, leak. To prevent this from happening, in addition to taking measures to prevent heat and cool down, the filling coefficients should also be filled according to the regulations. In the case of gases, the coefficient of expansion is greater and the gases are generally filled in cylinders, which are at risk of explosion as the temperature rises and the pressure becomes too high. 2. Increased temperature accelerates oxidative decomposition and spontaneous combustion Influenced by environmental factors such as temperature and humidity, many hazardous chemicals are prone to decomposition when heated, releasing oxygen and even oxygen atoms, which oxidise other substances and give off a lot of heat at the same time. If ventilation is poor, the heat will accumulate and not dissipate, resulting in a rise in temperature, which in turn will accelerate the rate of oxidation and generate more heat, prompting the temperature to continue to rise. Wuxi Nanquan Pressure Vessel Co., Ltd. has done the following measures 1. Strictly control the temperature Set up a water storage roof for the warehouse or set up cooling water pipes on the roof of the warehouse to cool the warehouse when the temperature is above 30 degrees Celsius, so that the temperature in the warehouse is kept below 28 degrees Celsius. In the warehouse roof laying gravel sacks, can enhance the heat insulation performance of the roof, but also the warehouse roof, external walls and window glass painted white, the use of white on the reflection of sunlight, reduce the absorption of radiation heat, to achieve the role of cooling. According to the nature of the goods and packaging, you can pour well water, put ice on the ground in the warehouse, and install air conditioning to cool down the temperature if possible. Some warehouses can open windows in the morning and evening and at night to ventilate and let in cold air, and close doors and windows at noon to prevent hot air from entering. 2. Storage Tanks to be cooled The top of the Storage Tank should be set up with a cooling device, and when the temperature reaches above 30 degrees Celsius, turn on the cooling water pump for spraying and cooling. The storage tank should not be filled too full, the tank is generally only 90% to 95% of the volume, leaving 5% to 10% of the volume space, which can prevent the hazardous chemicals in the tank from burning or exploding due to heat expansion. 3. Strengthen personnel management Personnel managing dangerous chemical warehouses must be trained in safety and qualified by examination, and be licensed to work. The warehouse management personnel should regularly inspect the warehouse and solve problems in time to ensure safety.
