|safety |data |sheets |readily |available |two |workers. |Employers |provide |worker |education |and |training
|and |ensure |appropriate |control |measures |to |protect |the |health |and |safety |of |workers. |Employers
|also |implement |workplace |labels |and |safety |data |sheets |are |necessary
Workers |- |ANSWER-Participate |in |WHMIS |2015 |training |programs; |take |all |necessary |steps |to |protect
|themselves |and |their |coworkers |and |participate |in |identifying |and |controlling |hazards
Exemptions: |certain |hazardous |materials |exempt |from |the |requirements |of |old |WHMIS |still |remain
|exempt |from |the |requirements |of |WHMIS |2015 |including |- |ANSWER--Small |capacity |containers |100
|mL |or |less: |hazardous |products |packaged |in |small |volume |containers |are |exempt |from |the
|requirements |to |bear |precautionary |or |hazard |statements |on |label. |Lab |users |might |notice |the |above
