Where personal protection equipment (PPE) is available for use at a facility, employees must be trained in the proper use of this equipment. This is a basic requirement for the use of all types of PPE, and one that is often overlooked for the rarely used Emergency Life Support Apparatus (ELSA). These self-contained breathing apparatus are designed for emergency escape only. With proper training, affected employees will be able to react quickly and properly in the event that use of an ELSA is required. Proper initial training with regular refresher training prepares employees to react quickly and correctly in an emergency.
