Manual No. 03358 Rev. I
3.2.5
Start the compressor, and bring it up to
operating temperature and pressure. The pressure must
be more than 50 psi, but must not exceed the blast
machine’s rated pressure.
3.2.6
Fill the machine with screened, clean, dry
abrasive that is manufactured specifically for abrasive
blasting.
3.2.7
Open the compressor air supply valve to
pressurize the air supply line. Listen for noise that
indicates any open lines or leaks.
3.2.8
Do not allow anyone around the blast machine
except machine tenders, who are appropriately attired in
approved personal protective equipment.
WARNING
Everyone, except for the blast operator or blast
machine tender, must stay clear of the blast
machine. The machine tender or blast operator
may pressurize or depressurize the machine at
any time, which could cause abrasive to vent
under pressure and cause dust and toxins to
become airborne. Noise is produced by the
sudden release of compressed air when the
machine is pressurized or depressurized. These
conditions could cause injury. Both the
operator and machine tender must wear
suitable personal protective equipment
including an approved respirator, plus
approved eye, face, and hearing protection.
3.2.9
When the blast operator is ready to blast, either
the operator or the machine tender, while standing back
and facing away from the concave filling head of the
blast machine and the exhaust muffler, closes the safety
petcock, preparing the machine for remote activation by
the control handle. Air should be heard escaping from
the orifice under the control handle lever but nowhere
else. The air escaping at the handle is an audible signal
meaning air is supplied to the blast machine, and will
activate if the control handle is pressed.
3.3 Blasting
Attire
WARNING
Before blasting, test the coating and substrate for
toxic materials (such as lead or other heavy metals,
or asbestos). These hazards require special
measures to protect the operators and the
environment.
No dust is safe to breathe. Abrasive blasting
produces harmful dust. Failure to wear approved
respirators could result in serious lung disease or
death. Blast operators must wear properly-fitted
and maintained NIOSH-approved, type-CE supplied-
air respirators approved for abrasive blasting.
During abrasive blasting, abrasive particles and
dust in the area around the blast machine and blast
nozzle become airborne. Everyone in the vicinity of
abrasive blasting must wear properly-maintained,
NIOSH-approved, respiratory protection and eye
protection appropriate for the job site hazards.
Noise generated by compressed air could cause
hearing damage. Everyone in the blasting area must
wear approved hearing protection.
3.3.1
Operators
and
anyone else that may be
exposed to the hazards generated by the blasting
process
must wear appropriate protective gear,
including abrasive-resistant clothing, leather gloves, eye
and hearing protection, and a NIOSH-approved Type CE
Supplied-Air Respirator.
3.4 Blasting
3.4.1
Don all protective blasting attire, per Section 3.3.
3.4.2
Hold the blast hose securely and point the
nozzle only toward objects intended to be blasted.
3.4.3
Pull back the safety lever lock and depress the
remote control handle. Within a few seconds the pop-up
valve will automatically close, and the blast machine will
pressurize to start blasting.
CAUTION
Be prepared for recoil from the blast hose.
Blasting should begin within a few seconds
after pressing the control handle lever.
