When conducting experiments in the laboratory, it is necessary to wear the appropriate protective gloves according to the specific situation to resist chemical erosion, cuts and other hazards, as well as to prevent accidental losses caused by slippery hands. There are many types of protective gloves suitable for laboratory use, and in order to better protect against various hazards, we need to carefully consider and choose a more suitable product.
How to choose protective gloves for laboratory use?
- Resistant to chemicalsIn the laboratory, the experimenter will often come into contact with corrosive chemicals. Such as acetic acid, nitric acid, sulfuric acid, sodium hydroxide, etc.. If the experimenter grasps the test tube with these chemicals with bare hands, it may lead to skin corrosion. Because the test tube will remain on the transparency of chemical reagents. The lighter will cause dry skin, peeling, itching, redness and swelling, the heavier will lead to serious skin diseases and burns.
- Cut prevention
Because most of the laboratory apparatus is glass products, inevitably there will be knocked flash. This time wear gloves to handle broken glass, can prevent hand scratches, cuts. Because the gloves form a protective barrier between the delicate skin and the hard glass, they can effectively prevent the latter from hurting the skin. Thus protecting the hand and hindering the subsequent class such as wound infection of many problems.
Today, most of the laboratory gloves in the fingertips, palm have a “micro numbing surface” design. This is mainly to provide a better grip for the experimenter. Most of the laboratory utensils are smooth surfaces. This makes the experimenter need to be extra careful when gripping the vessels, a little carelessness may be slipping from the palm of the hand. Now with the design to enhance the friction that is grip, gripping utensils will be more convenient.
How do I choose between latex and nitrile gloves?
The most common types of disposable gloves are nitrile gloves and latex gloves. In terms of performance, nitrile gloves are better than latex gloves. Secondly, because some people are allergic to latex gloves, nitrile gloves can avoid this situation by using nitrile raw materials, which do not cause allergies; at the same time, nitrile gloves are also better than latex gloves in terms of corrosion resistance and strong chemical resistance.
Precautions for using protective laboratory gloves
- Wearing gloves in chemical experiments can avoid skin contact with chemicals, but they must be used correctly to achieve the purpose of protection.
- Gloves should be worn when handling corrosive, toxic or unknown toxic substances, rough or sharp objects, very cold or hot materials, or operations with the potential for explosion.
- No one glove can provide complete protection against all kinds of injuries, and no one glove can prevent the penetration of all chemicals, so the choice of gloves should be based on an understanding of the circumstances of the glove’s protection against various drugs, its specific use and its characteristics (i.e., thickness and penetration rate and time) to determine which glove to use in which circumstances.
- Prior to use, gloves should be inspected for defects such as discoloration, punctures and cracks.
- Used gloves should be contaminated to determine whether they should be discarded, cleaned and reused or can be reused directly.
- If a glove is found to be damaged, it should be discarded immediately and hands should be washed, because if the chemical spreads through the glove to the hands, the skin will be more seriously contaminated than if no gloves are worn.
- When handling cryogenic liquids (e.g., liquid nitrogen), wear cold-resistant gloves that are very loose so that they can be removed quickly if the cryogenic liquid enters the gloves.
- When wearing gloves for experiments need to deal with other things, such as answering the phone, opening doors, operating elevators, writing experimental records, etc., you should take off your gloves beforehand to avoid unintentionally contaminating other objects with the chemicals on the gloves and hurting others.
- Do not share lab gloves, as sharing lab gloves can easily cause cross infection.
- Wash your hands before wearing lab gloves, wash both hands after taking off lab gloves, and rub some hand cream to replenish natural protective oils.
- heal or cover wounds before wearing lab gloves to stop bacteria and chemicals from entering the bloodstream.
- Do not ignore any skin erythema or painful itching, dermatitis and other skin diseases, if the hands appear dry, itchy, bubbles, etc., promptly consult a doctor.
