Laboratory safety knowledge

1. Fire safety

Fire protection facilities inspection: Ensure that fire protection facilities such as smoke alarms, fire extinguishers, fire blankets, fire sand, and fire sprinklers are in normal working order and are easily accessible. Emergency equipment: Emergency sprinklers and eyewash equipment should be in normal working order and be regularly inspected and maintained.

Safety passages: Keep fire passages unobstructed to ensure that people can evacuate quickly in an emergency.

2. Chemical safety

Orderly storage: Chemicals should be stored in an orderly manner and avoid stacking or mixing, especially prohibited chemicals and volatile and leaky reagents.

Ventilation conditions: Chemical storage areas should have good ventilation conditions and be away from heat and fire sources. Personal protection: When using chemicals, appropriate personal protective equipment should be worn, such as chemical protective glasses, protective clothing, gloves, etc.

3. Special equipment safety

Special equipment: Check whether the special equipment and safety accessories are expired. If they are expired and not inspected, they should be sent to relevant units for inspection in time. Equipment pipeline interface: Check whether the equipment pipeline, interface, etc. are loose, and repair or replace them in time. Safety accessories: Check whether the safety accessories such as sealing rubber rings are aging, and replace them in time.

4. Gas cylinder gas safety

Cylinder storage: Dangerous gas cylinders should be stored in a well-ventilated place away from heat sources and avoid exposure to the sun. Alarm device: Ensure that the gas alarm device is working properly, the cylinder is hung with a status information sign, and the information is accurate. Regular inspection: Regularly check whether the cylinder valve is leaking, whether the pipeline is damaged, and whether the anti-dumping device is firm.

5. Safety of electricity and water use

Power supply inspection: The laboratory capacity, plugs and sockets must match the power of electrical equipment, and no unauthorized modification is allowed; Wires and cables: No unauthorized pulling or connecting of wires and cables, no aging cables, flower wires and wooden distribution boards; Power connectors: The insulation of the power connectors is reliable, there are no exposed connecting wires, and the cables passing through the channel should have covers or sheaths; Water use inspection: The sink, floor drain and sewer are unobstructed, and the faucets and water pipes are not damaged.

Storage issues of hazardous chemicals in university laboratories

Complex types of hazardous chemicals

There are many types of hazardous chemicals involved in university laboratories, including flammable, explosive, toxic, and harmful. When storing these hazardous chemicals, they need to be classified and managed according to their chemical properties to prevent accidents caused by mutual reactions. However, in actual operations, due to the complex types of hazardous chemicals, managers often find it difficult to accurately grasp the characteristics of each hazardous chemical, resulting in hidden dangers in storage management.

Irregular storage of hazardous chemicals

The storage of hazardous chemicals follows certain specifications and standards, including the control of environmental factors such as temperature, humidity, and light, as well as requirements for stacking and isolation. However, in actual operations, some university laboratories have problems with irregular storage, such as chaotic stacking and failure to set up isolation areas. These problems may cause hazardous chemicals to react with each other or leak, thus causing accidents.

Insufficient investment in informatization

Informatization management is an important means to improve the level of storage management of hazardous chemicals. However, some university laboratories have insufficient investment in informatization, resulting in incomplete and inaccurate records of hazardous chemicals, making it difficult to conduct effective monitoring and management. In addition, insufficient informatization may also lead to problems such as expiration, loss, and loss of hazardous chemicals, posing risks to laboratory safety.
