Master in the control and prevention of chemical hazards, chemical

origin.

 

·         Use less toxic substances instead.

·         Change the production process, such as using a wet system instead of a dry one. So as not to cause dust to spread

·         Separate hazardous production processes

·         Create a cover for the production process completely. Not allowing chemicals to spread out

·         Install a local exhaust system

·         Machine tool maintenance

Chemical passageway

·         Maintaining a clean and tidy workplace

·         Installation of a general ventilation system
