Laboratory safety protection series - the selection of protective gloves.
In the laboratory, gloves are one of the important protective equipment, used to protect the hands of laboratory personnel** from harmful substances and dangerous goods. Proper selection and use of gloves is essential for laboratory safety. This article will introduce the common types of protective gloves in the laboratory, the selection principles and precautions to help experimenters better protect their own safety.
1. Types of protective gloves.
The main types of protective gloves commonly used in laboratories include:
1.Chemical protective gloves: mainly used to prevent the erosion and penetration of chemicals, suitable for various chemical experiments and when exposed to toxic and harmful chemicals. Chemical protective gloves are usually made of special materials, such as butyl rubber, neoprene, etc., which have good chemical resistance.
2.Antistatic gloves: mainly used to prevent static electricity from causing electric shock or other dangers to experimenters. Antistatic gloves are made of electrically conductive materials that conduct static electricity away and avoid charge accumulation. In the laboratory, antistatic gloves are required when conducting experiments such as flammable, explosive, and high voltage.
3.High temperature resistant gloves: mainly used to prevent burns on the hands in high temperatures. High-temperature gloves are usually made of materials such as asbestos, fiberglass, etc., and are able to withstand higher temperatures. Heat-resistant gloves are required when performing high-temperature experiments in the laboratory or when coming into contact with heat sources.
4.Disposable gloves: Disposable gloves are single-use protective gloves, usually made of plastic or non-woven materials. Disposable gloves are suitable for hand protection that does not need to be used repeatedly, such as handling disposable laboratory equipment, cleaning and hygiene, etc.
Second, the selection principle of protective gloves.
When choosing laboratory protective gloves, the following principles should be followed:
1.Understand the risk factors in the experiment: Choose the appropriate type of gloves based on the nature of the experiment and possible risk factors, such as the type of chemical, temperature, pressure, etc.
2.Choose the right glove size: Gloves that are too small or too large are not good for hand protection, so choose the right size of gloves to ensure that the gloves fit snugly in the hand.
3.Consider comfort and flexibility: On the premise of ensuring protective performance, gloves with better comfort and flexibility should be selected to facilitate experimental operation.
4.Pay attention to the expiration date and expiration date: No matter what type of protective gloves you have, they have a certain shelf life and expiration date, so you need to pay attention to check them and use them according to the regulations.
5.Follow national and laboratory safety regulations: When selecting and wearing protective gloves, national and laboratory safety regulations should be followed to ensure the safety of laboratory personnel.
3. Precautions for using protective gloves.
When using protective gloves, the following should be noted:
1.Check the integrity of the gloves: Carefully check the gloves for damage or loopholes before use, and replace them in time if they are damaged.
2.Wear and change gloves as required: Gloves should be worn correctly according to the regulations to avoid breakage during wearing. At the same time, gloves should be replaced in time according to the use of use, and expired or damaged gloves should be avoided.
3.Pay attention to hand hygiene: clean and disinfect hands before using gloves to avoid contamination of gloves and laboratory equipment. Hands should also be washed in time after use to maintain hand hygiene.
4.Avoid touching your face and nose while wearing gloves: Care should be taken to avoid touching your face and nose while wearing gloves to avoid contamination of your hands** or entry into your respiratory tract with harmful substances from gloves.
5.Precautions for storage and use: Different types of protective gloves have different storage and use requirements, and should be used and stored correctly according to the instructions. At the same time, care should be taken to avoid contact with sharp objects to avoid damage to gloves.
