If your risk cannot be lowered through elimination or substitution, there are 3 types of safeguards that you can use to protect employees. They are:
Engineering controls – are solutions built into your operation that are used without any action being required by employees. Examples: ventilation; automated dilution equipment.
Administrative controls – require action by the employee to follow. Examples: portable ventilation units; employee chemical exposure time limits.
Personal protective equipment – requires employers to properly identify and employees to maintain and wear. Examples: safety glasses; chemical resistant gloves; respirators.
