What Employers should understand is to know how heavy the consequences are just in case somebody is exposed to chemical. The kind of chemicals that they may encounter in the place and what protective measure and precautions should be done in order to promote safety. Both employers and employees should know how chemicals penetrate on the body and what affect it will cause to those who are exposed to it. Always remember that each chemical has its own way of penetrating the body through the nose, the mouth, any skin contact and eye contact. A lot of these could be learned on the process of chemical safety training.
