Use containment methods such as15. blast-cleaning machines and cabinets

to control the hazard and protect ad-

jacent workers from exposure.

Practice good personal hygiene to avoid16. unnecessary exposure to silica dust.

Wear washable or disposable protec-17. tive clothes at the work site. Shower,

and change into clean clothes before

leaving the work site to prevent con-

tamination of cars, homes, and other

work areas.

Use respiratory protection when source18. controls cannot keep silica exposures

below the recommended levels.

Provide periodic medical examina-19. tions for all workers who may be

exposed to crystalline silica.

Post signs to warn workers about20. the hazard and to inform them about

required protective equipment.

Provide workers with training that21. includes information about health ef-

fects, work practices, and protective

Air Supply

TO PREVENT

EXPLOSION:

Use only clean, dry, regulated,

compressed air to power this

Soda Blaster. Do not use

oxygen, carbon dioxide,

combustible gases, or any

other bottled gas as a power

source for this Soda Blaster.

1. Incorporate an in-line lter, shut-off

valve and regulator with pressure

gauge for best service, as shown in

the diagram above. An in-line shut-

off valve is an important safety

device because it controls the air

supply even if the air hose is rup-

tured.

Attach an air hose to the compres-2. sor’s air outlet. Connect the air hose

to the Male Coupler of the Soda

Blaster. Note: Use of quick coupler

is recommended, but not mandatory.

Note: Air ow, and therefore Soda Blaster

performance, can be hindered by

undersized air supply components.

The air hose must be long enough3. to reach the work area with enough

extra length to allow free movement

while working.

Close the in-line safety valve be-4. tween the compressor and the Soda

Blaster.

Turn on the air compressor according5. to the manufacturer’s directions and

allow it to build up pressure until it

cycles off.

Adjust the air compressor’s output 6. regulator so that the air output is

enough to properly power the Soda

Blaster, but the output will not exceed

the Soda Blaster’s maximum air pres-

sure at any time. Adjust the pres-

sure gradually, while checking the air

output gauge to set the right pressure

range. To do so, close Air Input ON/

OFF Valve (4). Pull out on the Quick

Disconnect Safety Valve (7) to stabi-

lize air pressure in the Storage Tank

(1).

If the Soda Blaster will not be used at7. this time, turn off and detach the air

supply, safely discharge any residual

air pressure, and release the throttle

and/or turn the switch to its off posi-

tion to prevent accidental operation.

Note: Residual air pressure should not be

present after the Soda Blaster is dis-

connected from the air supply. How-

ever, it is a good safety measure to

attempt to discharge the Soda Blaster

in a safe fashion after disconnecting

to ensure that the Soda Blaster is

disconnected and unpowered.
