1. Production and business entities should establish and improve the management system for labor protection products. It is necessary to strengthen the management of the purchase, acceptance, custody, distribution, renewal, and retirement of labor protection supplies, and supervise and educate employees to wear and use them in accordance with the requirements.
2. The provided protective equipment must meet national or industrial standards. It is not allowed to replace labor protection articles with currency or other articles, nor to purchase or use products that exceed the service life or inferior quality, so as to ensure that protective articles can exert their unique effects under emergencies.
3. In the wearing and use of labor protection articles, the following conditions must be prevented:
(1) People engaged in high-altitude operations do not fall down with their seat belts.
(2) Engaging in electrical work (or hand-held power tools) does not result in electric shock from wearing insulated safety shoes.
(3) wearing uniforms, wearing skirts or casual clothes in the workshop or on the construction site, or wearing uniforms but not wearing uniforms, open fronts, and not wearing cuffs, causing mechanical entanglement.
(4) The long hair does not fit into the work cap, causing the long hair to be mechanically involved.
(5) Wear gloves incorrectly. Some of the wearers do not wear them, causing burns, punctures, and other injuries. Some people shouldn't wear them, causing them to take their gloves and bring them to their hands. Even the arm can bring injuries.
(6) Do not wear proper goggles and face masks in time to make the face and eyes subject to splashing injuries or burns, or to strong light to cause visual impairment.
(7) Wear a safety helmet incorrectly. When an object falls or the head is struck, an accident is caused.
(8) Wearing protective safety shoes in the workplace is not in accordance with the regulations, causing foot injuries.

The transmission range of Zinc Selenide ZnSe-CVD is 0.5 - 20 µm.
ZnSe CVD used for high power CO2 laser optics at 10.6µm, for protective optics windows or optical elements in FLIR (forward looking infrared) thermal imaging equipment, optics for medical and industrial applications (optical plane parallel windows (plates, disks, blanks), wedged windows, optical meniscus, spherical and cylindrical lenses, prisms, resonator mirrors of CO2 laser).
The refractive index is near 2.4. Zinc Selenide has a very low absorbtion coefficient and is used extensively for high power infrared laser optic. It is non-hygroscopic.
Zinc Selenide (ZnSe) - transparent in wide spectral range from yellow (visible) to far IR. ZnSe material is a chemically inert, non-hygroscopic and highly pure product that is very effective in many optical applications due to its extremely low bulk losses, high resistance to thermal shock and stability in virtually all environments, easily machined.
Special care should be taken when handling Zinc Selenide as it is a toxic material. Always wear rubber or plastic gloves to avoid risk of contamination.
