The production of simple personal protective equipment

The production of simple protective equipment requires the selected material to be anti-virus, and the resulting equipment has a large filtering area and uniform air distribution.

(i) Simple gas masks.

The simple gas mask is made of a canister and a gas mask. Canisters are filled with filters and filter materials, and the steps to make them are as follows:

1, select the filter material. The commonly used adsorbent poisonous steam material is lime soil particles. The commonly used smoke filter material is sawdust, and a certain thickness of cotton pad and cotton fleece fabric filter effect is better. The insulating material used to make the mask should be made of a material that has certain strength and is soft and airtight, such as rubber cloth and artificial leather.

2. Make a simple canister. Use a hard paper tube or can box with an inner diameter and height of 8-10 cm as the canister shell. Evenly drill an air hole with a hole diameter of about 3 mm at the bottom of the tank. Use scissors to cut the mouth of the can into a nose. To adapt to the shape, a 5 mm diameter breathing port is opened on the bottom of the tank near the mouth to install the exhalation valve, and then loaded in order to become a canister. Generally loaded with 7 cm thick sawdust compaction to 5 cm, lime soil particles can be installed to 3 cm thick. If a sealed flexible material is affixed to the mouth of a canister and four pieces are fixed, it is a respirator (or poison cartridge) with a canister.

3. Make a simple gas mask. The selected mask material is cut into shells by size. The elastic strap is used to make the T-shaped headband size. The three ends of the headband are sewn to the parts of the hood that will contact the temples and the forehead, and then the upper part of the mask is attached with a medical tape and hooped on the canister. (Specific location try on OK). Adding two straps to the canister can increase the stability of the action. Using this method to make a simple gas mask, the mask material can be made of a transparent plastic film and no additional anti-toxic glasses are required.

(b) Protective masks.

1, alkaline anti-virus masks. Stack ordinary towels into 12 layers, add tape, and serve as a mask. Can also be made of 30-40 layers of gauze, before use, immersed in alkaline solution, such as 20% lime water, 10% soda water or grass gray water, remove and wring a little. Put on the hand and squeeze it to make it close to the turbinate cheeks.

2, loading anti-virus masks. Masks made of gauze or towel, 3cm thick activated carbon and clay (not sand) half, stir, made of rice grain size particles, dry and can be.

(C) simple anti-virus glasses.

Self-made simple antivirus glasses are made by making two coils of coarse iron wire, wrapping the cotton around the ring, making it closely fit around the eyes, using lenses of glass or transparent plastic, and sticking it on the frame with a tape, and then sewing. Lacing can be.

(d) Simple skin protection equipment.

Simple skin protection equipment should be made of isolated materials as far as possible. For example, rubber gloves, leather gloves, and cotton gloves can all be used to protect the skin of hands from radioactive dust and toxic agents. Foot protection can be made with protective footwear, rubber boots, and long rain boots. If necessary, use cloth and plastic sheets. Such wear-resistant flexible materials made of simple "legging" for lower limb protection. Raincoats, leather jackets, dustproof or plastic clothes, canvas, blankets, coats, quilts, umbrellas, etc. can all be used to protect the body in an emergency. Hats and scarves also have a protective effect on the head.

When using simple protective equipment, it is necessary to minimize the exposure of the skin, bind it securely, facilitate release, minimize the geographical time of exposure, and incinerate or bury it after use. Avoid secondary exposure when released.
