Chemicals that have explosive, flammable, poisonous, corrosive and other dangerous substances in the process of transportation, loading, unloading, storage, and storage, under certain conditions, can cause burns, explosions, personal injuries and deaths, and property losses. They are collectively referred to as hazardous chemicals. Products are usually divided into: flammable, highly toxic, highly corrosive, explosive, and strong oxidizer. How to store all kinds of hazardous chemicals safely has become the top priority in laboratory safety management. Hazardous chemicals storage management.
1. Dangerous chemicals are classified and stored separately, special warehouses, fixed locations, fixed zones, management by special personnel, and special vehicles for special transportation.
2. Explosive storage:
The explosives warehouse is a single-story building and is equipped with lightning rods. Storerooms are cool and ventilated, away from fire, heat sources, and direct sunlight. The temperature of the warehouse should be controlled at 15℃～30℃, and the relative humidity is generally controlled at 65%～75%. The internal lighting of the warehouse adopts explosion-proof lamps and the switch is located outside the warehouse.
The bottom of the package of explosive products is padded with about 20cm square wood or backing board, and there is no need to be padded with stones, cement blocks or steel that are prone to sparks due to impact or friction. Stacking height, density, length, spacing, wall spacing, column spacing, top spacing, etc. all need to be carefully considered, and hazardous chemicals storage safety management system shall not be excessively stored.
Flammable liquids are stored in a cool and ventilated warehouse, away from fire, heat sources, oxidants and oxidizing acids. For flammable liquids with a flash point below 23°C, the warehouse temperature should generally not exceed 30°C. Low-boiling point varieties must be refrigerated. Cooling measures should be taken in open storage tanks if the temperature is above 30°C. When storage tanks store commodities such as benzene and alcohol, their mechanical equipment must be explosion-proof and have an electrostatic grounding device.
Achieve the "five-double system", that is, double lock, double access, double use, double book account, double management, and check the accounts on schedule.
The sales volume, flow direction and storage volume of highly toxic chemicals shall be truthfully recorded to prevent the theft, loss or mis-sale or misuse of highly toxic chemicals. If the above-mentioned situation is found, it shall be reported to the local public security department immediately.
Establish a sales ledger for precursor chemicals, truthfully record the types, quantities, dates, and purchasers sold, and keep the ledger and certification materials for 2 years.
5. Dangerous chemicals in tanks and barrels should not be over-stored, the gas in the bottle should not be used up, and the residual pressure of 0.2MPa is generally retained. For each item, indicate the item's name, quantity, characteristics and rescue method. Comply with relevant safety and fire protection regulations, and set up corresponding safety facilities such as ventilation, explosion protection, pressure relief, fire protection, lightning protection, alarm, fire extinguishing, sun protection, temperature adjustment, elimination of static electricity, and protection of dikes according to the type and nature of the article, and Do:
The paint color of fire-fighting equipment fire-proof warning and indication signs is eye-catching and intact.
The fire separation distance meets the requirements, the fire resistance grade meets the national regulations, and the adjacent warehouses are separated by firewalls.
The layout of fire-fighting facilities is reasonable, and the fire-fighting passages are unobstructed.
Xunling Filtered Storage Cabinets provide a safe solution to store noxious or odorous chemicals, including volatile acid, alkali, flammable chemicals, and other hazardous or corrosive chemicals.
