Safeopedia Explains Emergency Life Support Apparatus
An emergency life support apparatus (ELSA) provides a constant flow of breathable air to the user for about 10 to 15 minutes. Generally, it consists of the following parts:
- A small compressed air cylinder
- A pressure release valve, pressure gauge and whistle attached to cylinder’s neck
- A hood with visor and/or a mouthpiece connected to a pipe that supplies air from the cylinder
- A carrying pouch with a waist belt or neck strap
All of these items are secured inside a pouch and kept in the passageways of buildings, oil and gas refineries, chemical areas, subways, tunnels, ships and other hazardous workplaces.
