I. Classification and application of occupational health standards
classification
1. Occupational health professional basic standards

4, occupational disease diagnostic criteria
5, occupational radiation protection standards
6, occupational hazard protection guidelines,
7. Occupational protection articles
8, labor physiological health, ergonomic standards
9. Occupational hazards testing and inspection methods
The code of the National Occupational Health Standard consists of uppercase Hanyu Pinyin. The compulsory health standard is “GBZ” and the recommended standard is “GBZ/T”. The national occupational health standard is an important basis for the detection and evaluation of occupational hazards in the workplace.
Role: Provide technical basis for various enterprises to implement administrative law enforcement and health supervision, improve working environment and protect workers' health. Article 7 of the Standardization Law of the People's Republic of China stipulates that all standards for the protection of human health, personal and property safety are mandatory standards, and health standards are an important basis for preventive and regular hygiene supervision.
Second, the application of GBZ1-2002, GBZ2-2002
1. Formulated principles: Under the premise of protecting the health of workers, it is economically reasonable and technically feasible. That is, the combination of security and feasibility.
2. Basis for formulating: Establishing exposure limits for harmful substances in the air of workshops is based on the physical and chemical properties of harmful substances, animal experiments, human toxicology data, occupational epidemiological investigations, and the conditions of labor hygiene. At the same time, it is in line with the standards of advanced countries.
3. Protection level: means that the concentration of toxic substances in the air does not exceed the exposure limit operating environment conditions, and continues to operate for several years. The harmful effects of some kind and definite exposures will not exceed a certain given frequency. . Each phase of health standards reflects the degree of protection provided to workers and reflects an acceptable level of risk.
4, high-risk groups: refers to a small number of people in contact with toxic and hazardous substances or carcinogens, due to individual differences, and its response to toxic substances to teach the general population to appear early and serious, this vulnerable group of people known as high-risk groups . Occupational health standards are not based on this part of the human-made basis.
Third, professional terms
Occupational exposure limit: refers to the exposure limit standard for occupational harmful factors, the long-term repeated exposure of workers to their occupational activities, and the allowable level of exposure to the body without causing acute or chronic harmful health effects.
1, the maximum allowable concentration (MAC): refers to any representative sampling and measurement must not exceed the concentration.
2. Time-weighted average threshold (TLV-TWA): refers to the time-weighted average concentration of a normal 8-hour working day.
3 Short-term exposure limit (TLV-STEL): This is the time-weighted average concentration for each contact time not to exceed 15 for no more than TWA. This concentration refers to a concentration that cannot be exceeded at any time within 8 hours.

Galvanized Roller Shutter Door

Using advanced hot-dip galvanized material , precision roll forming production process, polyurethane foam that free of hydrofluorocarbon inside door, light weight, high strength, appearance nice. The doors have advantages of tamper anti-theft , noise isolation thermal insulation and corrosion resistance;the doors are widely used in shops, garages, houses, supermarkets, warehouses and industrial plants,etc.

Depending on the characteristics of the buildings,we can choose interior, exterior and intermediate three different installation ways, doors stay in the upper part of door after rolling up , this could save garage space, and also could keep the garage clean and beautiful by prevent the mud, rain and snow ,etc going into the garage.
