What are the safety hazards in the chemical supply?

The main safety hazards in the chemical supply include improper storage, lack of qualifications, transportation violations, and chaotic management. If these links are out of control, they may cause serious accidents such as leaks, fires, and even explosions.
1. Hidden dangers in the storage process
Excessive and mixed storage risks: Failure to classify and store chemicals according to national standards, storing chemicals in excess of quantity or variety, especially mixing prohibited substances (such as oxidants and reducing agents), can easily cause violent reactions.
Long term backlog not cleared: Some laboratories or enterprises have not disposed of residual drugs from graduation projects for a long time, resulting in space occupation and potential reaction risks.
Lack of specialized facilities: Chemicals that are prone to drug and explosive production are not stored in dedicated storage cabinets, and the storage area lacks explosion-proof monitoring devices.
2. Qualification and compliance risks
Suppliers or transporters lack legal qualifications such as "Dangerous Chemicals Business License" and "Road Dangerous Goods Transport License", leading to loss of control at the source of the supply chain.
The newly developed process is directly industrialized without small-scale or pilot testing, or the chemical process used for the first time does not pass the safety and reliability demonstration, which poses a hidden danger of accidents.
3. Risks during transportation
Transport vehicles are not equipped with satellite positioning and video surveillance systems, making it impossible to achieve dynamic monitoring throughout the entire process.
During high temperature periods, illegal transportation of flammable and explosive materials, or failure to use universal pipeline filling systems for liquefied gas loading and unloading, increases the probability of leakage and explosion.
The packaging does not comply with UN standards, the labeling is unclear, and there is a lack of MSDS documents, which increases the risk of misoperation during transit and use.
4. Defects in management system
The safety ledger records are incomplete, and the "five double" management system (two person receiving and dispatching, two person bookkeeping, two person double locking, two person transportation, and two person use) has not been implemented, especially in the management of precursor drugs/explosive chemicals, where loopholes are prominent.
The detection and alarm device is not regularly calibrated, such as the CO alarm repeatedly sounding without analyzing the cause, losing its warning function.
The employees have not received training before taking up their posts, the special operators operate without certificates, and their safety awareness is weak.
