9. 1. 1.2 inspection contents
(1) The key points of symptom inquiry are hypertension, history of heart disease and family history of mental illness. Have you had dizziness in the past year?
History of syncope
(2) Physical examination
A. The routine physical examination focuses on blood pressure and heart.
B. Routine examination and color discrimination of ophthalmic examination
C. Attention should be paid to the mobility and flexibility of limbs joints during surgical examination, especially the mobility and flexibility of hand joints.
(3) Laboratory and other inspections
A. Required items include blood routine, urine routine, electrocardiogram and serum ALT.
B. Selective EEG (those with a history of dizziness or syncope)
Question 2: What are the occupational hazards of electrical ozone?
nitrogen dioxide
Manganese dioxide or chromium (covered electrode type)
ultraviolet ray
carbon monoxide
Welding smoke
Question 3: What are the occupational hazards of electrical work? Power frequency electric field and high temperature. If it is high pressure, there is also the toxic harm of sulfur hexafluoride.
PS. I'm talking about the power transformer, and upstairs I'm talking about the welding repairman.
Question 4: What are the occupational hazards of electricians? There are seven harmful factors in arc welding operation.
Arc radiation, smoke, toxic gas, radiation, noise, high-frequency electromagnetic field and high temperature, etc.
Arc lamp:
Strong ultraviolet rays are harmful to human body, even short-term contact can cause tears in eyes and great pain. Ultraviolet rays can also burn the skin, causing redness, itching and peeling. Too long will cause cataracts and eye diseases, and severe blindness.
Welding smoke:
Excessive welding smoke will lead to welder's pneumoconiosis, manganese poisoning, fluorine poisoning and metal smoke fever.
Toxic gas:
It can cause eye, nose and respiratory symptoms, and in severe cases, it can lead to bronchitis and pneumonia.
Radioactive substances:
Severe back can cause diseases of the central nervous system, hematopoietic organs and digestive system.
High frequency magnetic field:
Can cause dizziness, fatigue, memory loss, blood pressure fluctuation, palpitation, chest tightness, emaciation, mild anemia and so on. .
Noise:
The main hazards are: noise damage, noise deafness and the harm of nervous system and vascular system.
As long as effective protective measures are taken, the harmful factors in the welding process and their harm to the health of welders can be reduced or weakened. .
Question 5: What are the occupational hazards of electrical work? Not a welder, but a low-voltage electrician. Low-voltage electricians have basically no occupational hazards, and the electromagnetic radiation is very small, which will not cause harm to the body. .
Question 6: Do people engaged in the electrical industry have to have a physical examination of occupational diseases? Hello!
Whether it is necessary to have an occupational disease physical examination depends mainly on whether you will be exposed to occupational hazards at work.
1, the most common electrician: power frequency electric field. General electricians will be exposed to the power frequency electric field because there will be more people working in the distribution room.
2. For example, if you need to go to the workshop to do circuit maintenance, and your workshop is noisy, then you will also be exposed to noise, so you need to do a physical examination of occupational diseases.
Question 7: What are the hazards of welder's occupational health examination? The harm of argon arc welding is similar to that of general electric welding. Argon plays a role in protecting the weld from oxidation. Argon is an inert gas, which is harmless to human body.
Mainly depends on what kind of covered electrode, welding materials, mainly welding dust.
Question 8: What is the difference between workers engaged in or exposed to occupational hazards? Worry refers to directly engaging in related work with occupational hazards.
Contact means that you are not directly engaged in the work with occupational hazards, but you can be exposed to occupational hazards at work.
For example, welder's pneumoconiosis and welding dust are all occupational hazards. Welders are workers engaged in occupational hazards, and other types of work working in the same place as welders are workers exposed to occupational hazards. Although the latter is not a welder, he may suffer from welder's pneumoconiosis because he works in an area with welding dust.
Question 9: What are the occupational hazards that electricians may involve in electromagnetic radiation and power frequency electric fields?
Question 10: Is it necessary for all post personnel involved in occupational health hazards to undergo occupational health examination? Physical examination shall be carried out according to the Technical Specification for Occupational Health Surveillance (GBZ 188-2007), including pre-job physical examination, on-the-job physical examination, off-job physical examination, emergency physical examination and follow-up physical examination. If the on-site monitoring of harmful factors meets the requirements, it can be done once every two years, otherwise it will be done once a year.
