(1) Written plan.

(a) You must develop a written plan for emergency situations for each construction operation where there is a possibility of an emergency. The plan must include procedures where the employer identifies emergency escape routes for her or his employees at each construction site before the construction operation begins. You must implement appropriate portions of the plan in the event of an emergency.

(b) The plan must specifically provide that employees engaged in correcting emergency conditions are equipped with the appropriate personal protective equipment and clothing as required in WAC 296-155-17317 and 296-155-17319 until the emergency is abated.

(c) The plan must specifically include provisions for alerting and evacuating affected employees as well as the applicable elements prescribed in WAC 296-24-567, "Employee emergency plans and fire prevention plans."

(2) Alerting employees. Where there is the possibility of employee exposure to MDA due to an emergency, you must develop means to promptly alert employees who have the potential to be directly exposed. You must immediately evacuate affected employees not engaged in correcting emergency conditions in the event that an emergency occurs. You must also develop means for alerting other employees who may be exposed as a result of the emergency.
