An emergency can happen at any time and could result in a mass confusion. An emergency preparedness plan will ensure that workers are aware of their responsibilities and are trained to respond quickly and appropriately. This will minimize the amount of the loss to people, equipment, materials and the environment. Emergency preparedness plans should be finalized in writing and cover all potential emergencies. Floor plans outline exit routes, hazardous areas and products should be detailed and procedures posted. The plan should be coordinated with local emergency responders and periodic practice drills carried out. Emergency preparedness plans should be communicated to everyone including contractors with their responsibilities clearly outlined. While they may be rare, fires, severe weather, chemical spills or exposures, severe injuries, medical emergencies, workplace violence and other emergency situations often occur without warning.
