Blast and Air Hoses:
All air hoses, blast hoses, control hoses, and wires should be inspected
daily for wear, dry rotting, cracking or leakage. Repair or replace any hoses or wires that show
any signs of wear, leakage or other damage. Damaged wires and/or hoses can cause system
malfunctions and can result in serious injury or death to operating personnel.
Blast hoses are a high wear component of the abrasive blast system. Sharp bends in the blast
hose create high wear points resulting in soft spots that can rupture while blasting. Check the
full length of the blast hose assembly for soft spots caused by wear. To protect against serious
injury to personnel replace blast hoses with soft spots. Note: Static electricity is generated by
the abrasive flow through the blast hose. To minimize chance of electric shock to operators only
use static dissipating blast hose and install a grounding strap on the abrasive blaster.
Worn blast hose assemblies can rupture while blasting and the resulting abrasive blast stream
can cause serious personal injury.
Static electric shock hazard. To minimize the chance of static electric shock install a grounding
strap on the abrasive blaster and only use static dissipating blast hose.
Longer blast hoses require longer time to dissipate the blast stream when the deadman is
released to end the blast operation. This extended dissipation time increases the risk of injury
should there be an accidental loss of control of the blast hose.
8.7.
Blast and Air Hoses:
All air hose, blast hose, and threaded couplings have pin holes that align
when connected. To protect against accidental hose disconnections safety pins must be installed
through these holes. Each hose connection must also include a hose whip check that will hold
the hose if there is an accidental disconnection. Connect one loop to each side of the connection
and stretch out as shown in Figure 8.2 below. Check hose connections daily and replace
missing or damaged pins and whip checks.
Failure to install safety pins on all air and blast hose couplings can result in hose disconnects
and could result in serious injury or death.
