Loading, unloading and transportation of combustible substances

1 Vehicle and vessel transportation safety

inflammable substances shall be loaded and unloaded at designated special stations or docks in the suburbs or far away from the urban area after being shipped, transferred or arrived by rail or water Vehicles and vessels carrying inflammable substances shall be clearly marked with dangerous goods The vehicle and vessel shall be equipped with fire-proof, explosion-proof, waterproof, sun proof and other necessary fire-fighting facilities After unloading, the vehicle and vessel shall be cleaned and treated as necessary

train shipment shall be handled in accordance with the transport rules of dangerous goods of the Ministry of railways The vehicle shall be transported according to the specified time, the specified route and speed. When parking, it shall maintain its shape and characteristics with other vehicles and high-voltage wires above the glass transition temperature of the material, and keep a certain safe distance from open flames and densely populated places During shipping and berthing, ships should keep a certain safety distance from other ships, wharf warehouses and densely populated areas. The order volume of injection molding machines in the fourth quarter fell by nearly 5 percentage points compared with the same period in 2012

2. Pipeline transportation safety

high pressure natural gas, liquefied petroleum gas, petroleum crude oil, gasoline or other fuel oil are generally transported by pipeline In order to ensure safe transportation, multi-functional safety facilities should be installed on the pipeline, such as flame detectors with automatic alarm and shutdown functions, automatic fire extinguishing systems and closed-circuit TVs to remotely monitor the operation of the pipeline For example, under normal circumstances, the flow readings everywhere in the pipeline should be the same, and the pressure readings should be kept constant. Once the readings at a certain place change, it can be immediately concluded that there is a leak at that place Take emergency measures immediately to minimize the loss

3. Loading and unloading operation safety

loading and unloading 4. Due to the vibration of the pressure blasting testing machine during the transportation process, the connection of various pipelines or valves may become loose. The general safety requirement is to safely approach the top cover of the vehicle, which is particularly important for top loading and unloading Measurement, sampling and other operations are the same This requires the erection of appropriate ladders, loading platforms, gangways, and permanent handrails on vehicles All inflammable substances shall be loaded and unloaded with corresponding fire prevention and explosion-proof fire-fighting facilities

when loading and unloading combustible solids, it is necessary to load and unload with care to prevent impact, rolling, heavy pressure and friction

during the loading and unloading of flammable liquid, the liquid vapor may diffuse to the whole loading and unloading area, so it is necessary to have fire-fighting facilities matching the whole loading and unloading area If combustible liquid vehicles and ships use gas pressure unloading, the compressed gas should use inert gases such as nitrogen The gas pipeline used for unloading should be configured with a set value not greater than 0 to ensure the accuracy and stability of the test results Pressure reducing valve of 14MPa, and vent valve with slightly higher pressure, about 0.17mpa The loading and unloading area shall be equipped with water supply pipes and hoses to flush the spilled liquid during loading and unloading
