Storage instructions for chemical reagents
The storage of chemical reagents is an important part of laboratory safety management. Proper storage not only ensures the quality and performance of reagents, but also effectively prevents accidents from occurring. Here are some instructions on the storage of chemical reagents:
Storage principle
1. Classified storage: Chemical reagents should be classified according to their properties, such as flammable and explosive reagents, toxic and harmful reagents, corrosive reagents, etc., and should be stored separately in designated safety cabinets or storage rooms.
2. Clear labeling: Each reagent bottle should be labeled clearly, indicating the name, concentration, hazard level, production date, expiration date, and other information of the reagent for easy management and use.
3. Sealed storage: Most chemical reagents should be sealed to prevent air, moisture, or other impurities from entering and affecting the purity of the reagents.
4. Avoid light storage: Light sensitive reagents should be stored in a cool, dry, and dark place. If necessary, brown bottles or black plastic bags can be used to block light.
5. Temperature control: Some reagents are sensitive to temperature, and appropriate storage temperatures should be set according to their properties, such as refrigeration, freezing, etc.
Storage requirements for special reagents
1. Flammable and explosive reagents: They should be stored in explosion-proof cabinets, away from sources of fire and heat, and kept well ventilated. Strictly follow the operating procedures during use to avoid sparks or high temperatures.
2. Toxic and harmful reagents: They should be stored in dedicated toxic and harmful reagent cabinets, locked for management, and strictly controlled for usage permissions. Wear personal protective equipment such as gloves, masks, goggles, etc. when using.
3. Corrosive reagents: They should be stored in corrosion-resistant storage cabinets, avoiding contact with metals or other corrosive substances. Special care should be taken when using to avoid splashing onto the skin or eyes.
4. Oxidizing and reducing agents: They should be stored separately to avoid contact and reaction. Meanwhile, they should also be kept away from flammable and explosive materials.
Storage environment
1. Drying: Keep the storage room dry to prevent the reagents from getting damp and deteriorating.
2. Ventilation: Maintain good ventilation conditions to avoid the accumulation of harmful gases.
3. Cleaning: Regularly clean the storage room and keep it clean and free of debris.
4. Safety facilities: Equip necessary fire-fighting equipment such as fire extinguishers, eye wash stations, emergency showers, etc., and ensure that they are in good condition.
Management system
Inventory registration: Newly purchased reagents should undergo inventory registration, recording information such as the name, quantity, manufacturer, and production date of the reagents.
Regular inspection: Regularly inspect stored reagents, including their appearance, expiration date, sealing, etc., and promptly address any issues found.
Usage record: Establish a reagent usage record system to record information such as the usage time, purpose, and amount of reagents for easy tracking and management.
Personnel training: Regularly train laboratory personnel on chemical safety knowledge and operating procedures to enhance safety awareness and operational skills.
