Title: Hazardous Chemicals
1Hazardous Chemicals
2 Why HazCom?
- OSHA has established the rule on Hazard
Communication - to reduce injuries and illnesses related to
chemicals in the workplace. HazCom requires all
operations - to evaluate safety concerning chemical
hazards by a written hazard communication
program labeling containers providing access to
msdss and initial - employee training.
-
3HazCom is based on two Safety and Health
principles
- Employees have a right to know about the chemical
hazards where they work - Employees have the responsibility to know about
chemical hazards at their mines.
4 What does HazCom require?
- HazCom requires employees to be informed about
chemical hazards. - HazCom training increases both knowledge and
awareness, to create better work procedures and
safer behavior, while reducing injuries and
illnesses related to chemicals.
5 HazCom
- When put in effect, HazCom should result in
better hazard identification and assessment more
consistent use of personal protective equipment
and greater awareness and care when working near
hazardous chemicals.
