Abrasi-Blast™ Supplied-Air Respirator
The Abrasi-Blast Respirator provides respiratory and upper
body protection for workers in shipbuilding, the construction
industry, utilities, and other applications where blasting with
abrasives is performed.
A complete Abrasi-Blast Respirator is made up of a hood,
facepiece with lens housing, breathing tube, cover lens
cartridge assembly, flow-control device, approved air-supply
hose, and support belt.
During blasting operations, the lens of the Abrasi-Blast
Respirator is protected by 2 to 4 flat glass cover lenses
mounted in a special foam material. Each cover lens is
removed by integral pull tabs when it becomes so abraded
that vision is reduced. There is no need to stop to change
lenses, as is necessary with most conventional blasting
hoods. Approved by NIOSH.
For more complete information, see Bulletin 0112-37.
