4.2
Operator Safety Equipment
WARNING
Before blasting, test the coating and substrate
for toxic materials (such as lead, other heavy
metals, or asbestos). These hazards require
special measures to protect the operators and
the environment.
Obtain a safety data sheet (SDS) for the blast
abrasive to identify hazardous substances.
Silica sand (crystalline) can cause silicosis,
lung cancer, and breathing problems in
exposed workers. Slag abrasives may contain
amounts of toxic metals
such as arsenic,
beryllium, and cadmium. Any abrasive dust has
potential to cause lung disease.
Abrasive blasting operations can create high
levels of dust and noise. No dust is safe to
breathe. Abrasive blasting can produce harmful
dust. Failure to wear NIOSH-approved
respirators can result in serious lung disease or
death. The respirators must be properly-fitted
and maintained. Use only 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
working in the vicinity of abrasive blasting must
wear properly-maintained, NIOSH-approved,
respiratory protection and eye protection
appropriate for the job site hazards.
Loud noise generated by the use of
compressed air can cause hearing damage.
Everyone in the blasting area must wear
approved hearing protection.
It is the employer’s responsibility to train
employees to identify hazardous substances
and to provide suitable policies, procedures,
monitoring, recordkeeping, and personal
protective equipment.
4.2.1
Operators and anyone else exposed to the
hazards generated by abrasive blasting must wear
appropriate protective gear, including abrasive-resistant
clothing, leather gloves, eye and hearing protection, and
a NIOSH-approved Type CE supplied-air respirator.
4.2.2
Don all protective blasting attire outside the blast
area in a clean nonhazardous environment free of
contaminants, where the air is safe to breathe.
4.2.3
When finished blasting and after cleanup is
completed, remove the respirator and protective clothing
outside the blasting area in a clean environment free of
contaminants where the air is safe to breathe.

Insert Lance into Optional Hopper
‒
Figure 6
4.3.1
The hopper and cart assembly must be placed
on a firm and level surface.
WARNING
The four-wheel cart rolls easily. It must remain
on sound, level ground. Do not place the cart
on scaffolding. Do not use on elevated surfaces
unless it is adequately anchored to prevent
movement. Failure can result in injury.
4.3.2
Make sure the cart’s rear support bar is down.
4.3.3
Remove any foreign material that may have
fallen inside the hopper.
4.3.4
Insert the lance about halfway into the
connecting collar, making sure the air-intake holes
remain outside the collar. Tighten the thumbscrew to
secure the lance.

4.3.5
Pour
abrasive
into the hopper; remove any
foreign material that may fall in. Do not fill the hopper to a
level that impairs easy maneuvering. If preferred, bagged
abrasive may be placed inside the hopper, and the lance
inserted into the bag as described in Section 4.4.
4.4
Insert Lance into Bagged Abrasive
‒
Figure 7
4.4.1
Abrasive may be kept in the bag or poured into
a hopper, bucket, or similar container. Insert the lance
into the abrasive, making sure the upper (air-intake)
holes remain open and outside of the abrasive.
4.4.2
To use bagged abrasive, pierce the bag with the
pointed end of the lance. Insert the lance into the
