The ISI CEEBA provides respiratory protection for escape from atmospheres that have suddenly become Immediately Dangerous to Life or Health (IDLH). The unit is totally self-contained inside the
bright carrying pouch which can be stored in work areas or carried around the waist, around the neck, or over the shoulder. Should an environment become IDLH, the user would simply remove the hood
from the pouch, turn the cylinder valve on, don the hood and escape. It is that simple and quick! Unit is constant flow not "on-demand".With your choice of clear Polyurethane hoods for cold areas
or clear PVC hoods for warm weather areas there are no adjustments to make. The hood allows full peripheral vision even with long hair, facial hair or glasses.
