Dangerous goods safety protection measures and protective equipment (4)

(3) Hand protection products

Hand protection products are divided into 12 categories according to their protective functions, namely general protective gloves, waterproof gloves, cold-proof gloves, anti-virus gloves, anti-static gloves, high-temperature gloves, X-ray gloves, acid and alkali-proof gloves, oil-proof gloves, and vibration Gloves, cut-resistant gloves and insulating gloves

The hand is the most vulnerable part of a chemical laboratory accident

1) Secondary gloves

Disposable gloves are comfortable to wear and feel like a second layer of skin.

This kind of disposable gloves is not suitable for handling highly corrosive and allergic items due to its thinness and low strength.

2) Chemical protective gloves

Chemical protective gloves can prevent chemical penetration and are made of a variety of synthetic materials, such as latex (Figure 8-27), polyvinyl chloride (PVC), polyvinyl alcohol (PVA), nitrile , butyl synthetic rubber, and neoprene And natural rubber (Figure 8-28) and so on

3) Woven gloves

The types of woven gloves can be roughly divided into: general-purpose gloves made of polyester, nylon and cotton; cotton products are divided into yarn (Figure 8-29), pure cotton (Figure 8-30) and canvas (Figure 8-31) ) And so on

Matters needing attention in the selection and use of gloves

The selection of gloves and the correct use of gloves are directly related to the health of the hands
.
Pay attention to the following points in the process of choosing and using gloves

(1) The selected gloves should have sufficient protective effect

(5) Do not arbitrarily throw away the contaminated gloves after use, they should be placed in a special collection bucket as hazardous waste disposal
.

(6) Do not wear gloves out of the lab, but can not touch the items caught outside the laboratory, such as pressing a button, turn the handle and so on
.

(7) When removing gloves, you must pay attention to the correct method to prevent harmful substances contaminated on the gloves from contacting the skin and clothes, causing secondary pollution
.

(8) Do not share gloves.
