What is the difference between heavy chemical protective clothing and light chemical protective clothing?

Always when customers buy chemical protective clothing, they have encountered some doubts, such as the difference between heavy chemical protective clothing and light chemical protective clothing, companies involved in liquid ammonia need to configure heavy chemical protective clothing, or light chemical protective clothing? Chemical protection clothing when buying, how to choose and so on.

While telling the difference between the two, we must first understand how the two are defined:

1. Heavy-duty chemical protective clothing: It is also class A chemical protective clothing, fully enclosed chemical protective clothing or airtight chemical protective clothing. It is the highest level of protection in the category of chemical protective clothing, and its material is rather special. It is often used in fire rescue operations. , chemical leakage and other occasions. Heavy chemical protective clothing is called airtight protective clothing, because it can effectively prevent the invasion of toxic gases.

2. Lightweight chemical protective clothing: The definition is broad. Chemical protective clothing other than heavy chemical protective clothing can be defined as light chemical protective clothing, which can effectively prevent the invasion of chemical solvents, dust particles and viruses. Protection class B, C and D chemical protective clothing are all classified as lightweight chemical protective clothing. Its scope of application is very wide, and it is used in medical and health care, chemical plant operations, spraying industry, and so on.

The difference between the two, we analyze from the following points:

Material material
a. Material thickness: Heavy chemical protective clothing is more thick than the material of light chemical protective clothing
b.Material types: Heavy chemical protective clothing is generally flame-retardant cloth coated with PVC, polymer anti-chemical film, polyester fiber and other fabrics; while light chemical protective clothing is mostly flame-retardant cloth coated neoprene.

2. Color marking The color of heavy chemical protective clothing is mostly standard yellow, while light chemical protective clothing is orange.

3. Sealing performance

The protective performance of heavy chemical protective clothing is better than that of light chemical protective clothing. It encloses the entire person inside the chemical protective clothing, adopts a gas-tight zipper and double-layered plastic strips. Lightweight chemical protective clothing, in general, protects the entire body, while the face needs a separate gas mask to protect against toxic substances.

4. Flexibility and comfort

Heavy-duty chemical protective clothing is relatively bulky and completely closed, so wear and detachment are generally both at the same time, and because of the special nature of the material, people are very inflexible after wearing it. Lightweight chemical protective clothing is lighter in weight, easier to wear, more flexible in operation, and highly flexible. It is more rapid and convenient in general chemical operations and rescue.

5. Related accessories

Heavy duty chemical protective clothing must be equipped with an air respirator because it is an enclosed space and requires air supply. Lightweight chemical protective clothing, the configuration is relatively flexible, if it is emergency rescue, the operation of a longer time, you can external air respirator, if the material is not toxic, with a dedicated full gas mask on it.

If it is a laboratory operation, with a normal half mask gas mask and protective eye mask to meet the requirements.

6. Price

The price of light chemical protective clothing is much lower than that of heavy chemical protective clothing, which is generally about half of the normal heavy price. The average market price of heavy chemical protective clothing is now 8,000 to 10,000 yuan, while light chemical protective clothing is under 4,000 yuan. If it is ordinary liquid splashing, the price of chemical protective clothing will be around 300 yuan.

7. Applicable occasions

Lightweight chemical protective clothing is not suitable for wearing on toxic, hazardous gas fire scenes, accident scenes or workplaces. It applies only to steel mills, petrochemical plants, telecommunications, aviation, emergency medical departments, and chemical plants.

Heavy chemical protective clothing is used by firefighters when working on site with hazardous chemicals or corrosive materials. Mainly used in Class A environment (such as: toxic and hazardous workplaces, unknown toxic and hazardous substances, doses of the environment); biochemical environment; environmental detection unit; handling of dangerous goods.

After understanding the differences between heavy-duty and light-duty chemical protective clothing, we can choose which type of chemical protective clothing according to our actual use situation. But just knowing that heavy light is not enough.
