In general, the employer must:
- Assess the workplace to identify employees exposed to hazards from flames or from electric arcs;
- Make reasonable estimates of the incident heat energy of any electric-arc hazard to which an employee would be exposed;
- Ensure that employees exposed to hazards from flames or electric arcs do not wear clothing that could melt onto their skin or that could ignite and continue to burn when exposed to flames or the estimated heat energy;
- Ensure that the outer layer of clothing worn by an employee is flame resistant under certain conditions; and
- With certain exceptions, ensure that employees exposed to hazards from electric arcs wear protective clothing and other protective equipment with an arc rating greater than or equal to the estimated heat energy.
