What personal protective equipment to wear in the laboratory
Respiratory protection
In the course of the experiment, some chemical reactions will occur to produce toxic and harmful vapors or gases, which will cause respiratory tract injuries to the staff. In this way, you need to wear personal respiratory protective equipment. The more common ones are 3M gas masks or gas masks. Specific needs to be selected according to the degree of hazard of toxic gases on site, if the toxicity is greater, it is recommended to choose a gas mask.
Eye and face protection
1. Protective goggles or anti-chemical glasses: The eyes and face are the most vulnerable parts of the laboratory, so their protection is particularly important. In the laboratory working environment, the experimenters involved in solution reagents must wear safety protective glasses.
2. Eyewash: When chemical solvents splash into your eyes, you should immediately rinse them thoroughly with the eyewash. When rinsing, the eyelids should be opened, carefully rinse with tap water for a few minutes, then rinse with distilled water, and then go to the medical office for treatment. Eyewash can generally choose wall-mounted eyewash or portable eyewash.
3. Face screen: Face protective equipment is used to protect the face and throat. In order to prevent possible explosions and splashes caused by experimental objects causing impact damage, you can wear a protective mask or screen made of plexiglass or polycarbonate.
Body protection
Personnel must wear chemical protective clothing when entering the laboratory, the purpose is to prevent the skin and clothing of the body from being contaminated by chemicals.
The most basic performance of chemical protective clothing is to be able to resist the corrosion of general chemicals. If the reusable chemical protective clothing is selected, it needs to be washed and stored with a corresponding solvent after use to prevent the chemical substances attached to the surface of the chemical protective clothing Secondary injury.
Hand protection
In order to prevent hand injuries in the laboratory, you can choose to wear different types of protective gloves as needed. Gloves must be worn when touching corrosive substances, objects with sharp edges (such as broken glass, wood, metal fragments), or substances that are too hot or too cold.
The most commonly used gloves in the laboratory are chemical-resistant gloves, but the materials of chemical-resistant gloves are many, such as polyethylene, nitrile rubber, PVC, latex, etc., because chemical-resistant gloves of different materials can protect chemical solvents The degree of protection is different, so it needs to be defined according to the specific use situation. (Glove selection, refer to)
In addition, after the experiment, the personnel should use neutral detergent to wash their hands repeatedly. The chemical protection gloves after use should be handled in a unified and centralized way, and can not be mixed with other garbage. Collar and safety protection remind everyone that scientific experiment verification is very important, but at the same time of work, the first principle is to ensure personal safety, wear appropriate personal protective equipment, and prevent it from happening.
