Introduction of personal protective glasses and masks

Goggles and face protection against major protective eye and face ultraviolet radiation, infrared, microwave, and electromagnetic waves, dust, soot, sand and metal debris, and a chemical solution sputtering damage.

( 1 ) Protective glasses are usually made of flexible plastic and rubber. The frame is large enough to cover the user's eyes.

The anti-solid debris protective goggles are mainly used to prevent the mechanical damage to the eyes such as metal or gravel debris. Spectacle lenses and spectacle frames should be structurally strong and resistant to impact. The frame is mounted with a cover around the edge, which should have ventilation holes. Protective glasses can use tempered glass, glue glass or copper mesh protective glasses. Anti-chemical solution protective glasses are mainly used to prevent chemical damage to the eyes caused by irritating or corrosive solutions. Can use an ordinary piano lenses, the frame should be covered to prevent splashing into the solution.

Radiation-protective goggles are used to prevent the damage to eyes caused by radiation such as excessive UV rays. Lenses are made of special glass that reflects or absorbs radiation, but transmits some visible light . Lens plated with bright chromium, nickel, mercury or silver metal film may reflect radiation; infrared absorbing blue lens, green lens absorb ultraviolet and infrared, colorless lenses absorb lead X-rays and γ-rays.

( 2 ) Protective masks mainly include the following types:

Anti-spot and chemical solution splashed into the eye and face mask damaged, made of lightweight transparent plastic, multi-use plastic such as polycarbonate, the cover on both sides and the lower end of the two ears and the lower forehead of the lower end towards the neck, so that the mask Can cover face more comprehensively to enhance protection. Exothermic face masks can be made of single-layer or double-layer metal mesh except for the aluminum foil face mask in thermal protection clothing, but the double layer is preferred to allow some of the radiation to be blocked and dissipated in the air. If it can be chrome or nickel, it can enhance the anti-heat effect of reflection and prevent rust.

In addition, gas masks are used to provide effective protection for the respiratory organs, eyes, and facial skin of personnel. They are suitable for use by units such as troops, factories, mines, scientific research, ambulances, and fire protection.
