1. The severity of adverse health effects caused by occupational hazards is related to the level of exposure to hazards.
2. Pneumoconiosis caused by long-term inhalation of mineral dust is an irreversible disease. The control of productive dust should take comprehensive prevention and control measures and follow the eight-character policy of “leather, water, air tightness, wind, protection, management, education and investigation”. Dust masks cannot be replaced with cotton gauze masks and medical masks.
3. Those who are exposed to chemically harmful factors at work should pay attention to preventing chemical poisoning, strictly implement operating procedures, strengthen workplace ventilation, standardize the wearing of personal protective equipment, and regularly participate in occupational health inspections.

When working with harmful gases such as hydrogen sulfide and carbon monoxide, attention should be paid to preventing suffocation and irritant gas poisoning, strictly implement operating procedures, regularly overhaul equipment, prevent “running, running, dripping, and leaking” in the production process, and strengthen ventilation and daily monitoring. Set up warning signs in the workplace, install automatic alarm equipment, and wear oxygen-supply gas masks correctly.
5. Long-term exposure to high-intensity noise in the workplace can lead to hearing damage or even deafness. It is necessary to control the noise source and noise transmission, wear noise-proof earplugs or earmuffs, and conduct regular occupational health inspections.
6. When working in a high temperature and high humidity environment for a long time, attention should be paid to the prevention of heat stroke. Severe heat stroke can lead to death. The technological process should be reasonably designed, and technical measures such as ventilation and cooling should be adopted, and technical measures such as ventilation and cooling should be adopted. Wear a heat shield and wear heat-insulating, flame-retardant, ventilated and heat-resistant clothing.
7. Exposure to radiation at work can lead to acute and chronic radiation sickness, cancer or genetic disorders. When engaging in radiation work, radiation protection equipment should be used correctly and personal dosimeters should be properly worn. When entering a radiation workplace where large doses may exist, an alarm dosimeter should be carried.
8. Long-term work at a desk and bowing your head, fixed position work or forward sitting work should be done through stretching activities, intermittent rest, etc., to avoid the occurrence of cervical spondylosis, frozen shoulder and low back pain.
