1. Working environment: There may be harmful factors such as noise, dust, high temperature and harmful gas in the welding working environment, which needs to be evaluated.
2. Work content: whether it is necessary to contact with harmful substances, such as welding agent or lead-tin alloy, and whether it is necessary to smoke.
3. Operating time: Does the welding operation need to be exposed to harmful environment for a long time?
4. Personal protective measures: Whether the post provides corresponding personal protective articles, such as masks, protective glasses and protective gloves.
Considering the above factors comprehensively, if there is a high risk of occupational hazards in the welding and assembly post, it can be identified as an occupational hazard post. Pay attention to the prevention and control of occupational hazards, including providing necessary personal protective equipment, conducting regular occupational health examinations, and strengthening the training of employees' awareness of occupational hazards protection. It is suggested that relevant enterprises or organizations should abide by relevant laws, regulations and standards in occupational hazard management, and seek the support of professional occupational health consulting and evaluation institutions.
