What personal protective equipment should I know?

Hello, let me introduce personal protective equipment to you first.

Personal protective equipment is a necessary preventive equipment to protect the safety and health of workers in the process of labor. It uses a certain shield, belt or floating body to protect part or whole body of workers from external invasion by blocking, absorbing, dispersing and sealing. Using personal protective equipment is an important measure to prevent or reduce industrial accidents, occupational diseases and occupational poisoning.

Personal protective equipment can be divided into head protective equipment, face protective equipment, eye protective equipment, respiratory protective equipment, ear protective equipment, hand protective equipment, foot protective equipment and body protective equipment.

1. Head protection:

In order to protect the head from injury, protect the human head from injury or reduce the degree of head injury. Head protective equipment includes safety helmet, miner's safety helmet and electric welding safety helmet.

2. Face protection:

Personal protective equipment to prevent smoke, dust particles, metal sparks and flying debris, high temperature, electromagnetic radiation, laser, chemical splash and other injuries to the face is called facial protective equipment. According to the protection function, it can be divided into chemical protection panel, welding panel and radiation protection panel.

Chemical shielding-generally made of polycarbonate, it can prevent molten metal chemicals from splashing.

3. Eye protection: Particles and fragments of substances, sparks and heat flow, dazzling light and smoke will all cause harm to eyes. According to the protective function, it can be divided into chemical glass, impact glass, welding glass and dust-proof glass.

Chemical-resistant glasses-mainly used to prevent chemical damage to eyes caused by irritating or corrosive solutions.

Welding glasses-designed to protect the welder's eyes, more convenient and beautiful than welding face screen.

Anti-collision glasses-mainly used to protect dust particles, hard fragments and so on.

4. Respiratory protection

Protective articles for respiratory organs are protective articles to prevent harmful gases, vapors, dust and smoke from being inhaled through the respiratory tract or directly provide oxygen or clean air to users, so as to ensure that workers can breathe normally in dust, toxic pollution or anoxic environment.

Dust mask-personal protective equipment to prevent or reduce dust in the air from entering human respiratory organs.

Gas mask-personal protective equipment to protect people's respiratory organs, eyes and face from toxic substances such as toxic gases, dust and bacteria.

Air respirator-also called gas storage gas mask, sometimes called fire mask. It uses a compressed gas cylinder as the gas source, but the gas in the cylinder is compressed air.

5. Ear protection

Personal protective articles that can prevent excessive acoustic energy from invading the external auditory canal, prevent people's ears from being excessively stimulated by noise, reduce hearing damage, and prevent the adverse effects of noise on people. Ear protection products mainly include sound-proof earplugs, earmuffs and electronic earmuffs.

Soundproof earplugs-generally made of silica gel or low-pressure foam material and high-elastic polyester material. After the sound is inserted into the ear canal, it can isolate the sound from entering the middle ear and the inner ear (eardrum) to achieve the purpose of sound insulation.

Electronic earmuffs-with intelligent noise filtering function, the two pickups process the ambient sound through the built-in circuit to produce clearer sound to the ears.

6. Hand protection

Gloves with the function of protecting hands and arms worn by workers during labor are called hand protective articles, and people usually call them labor protective gloves. Protective gloves include chemical resistant gloves, insulating gloves, high temperature resistant gloves and arc resistant gloves.

Chemical gloves-used to effectively protect hands exposed to chemical solvents.

High temperature resistant gloves-special high temperature resistant gloves used in high temperature environment. Different high temperature resistant gloves can be selected according to the temperature of hand contact.

7. Foot protection

Foot protective equipment is a protective device to prevent harmful substances and energy from hurting workers' feet in the production process. People usually call it labor protection shoes (safety shoes). National standards are divided into dustproof shoes, waterproof shoes, cold-proof shoes, impact-proof shoes, antistatic shoes, high-temperature shoes, acid and alkali-proof shoes, oil-proof shoes, high-temperature shoes, non-slip shoes, puncture-proof shoes and electrical insulation shoes according to their protective functions.

8. Physical protection

Personal protective equipment is what we usually call protective clothing, which can fully protect the human body. Protective clothing can be divided into fully enclosed protective clothing, heat insulation clothing, fire protection clothing, radiation protection clothing, flame retardant clothing, dust-proof clothing, reflective vest, cooling vest and protective raincoat.

Fully-enclosed chemical protective clothing —— Chemical protective clothing consisting of hood, jumpsuit, chemical protective gloves and chemical protective boots, which is used together with positive pressure air respirator.

Thermal insulation clothing-also known as high-temperature protective clothing, is used to protect the human body from ignition, combustion and smoldering of various high-temperature injuries after contact with flames and hot objects.

Reflective vest-made of high-visibility reflective materials, users are generally traffic police, sanitation workers, etc.

The protective effect of various protective articles is limited. Some working environment conditions are complex and changeable, and personal protective equipment will not work if it exceeds the allowable protection range. Therefore, personal protective equipment must be used correctly and selected reasonably according to the harm degree of working environment to avoid accidents.
