Section 1:
1.1 General Safety
Use Professional Training
Operating high pressure water blasting equipment
requires professional training, including safe work
practices and procedures. Only professionally
trained personnel should be allowed to setup,
operate, or maintain high pressure water blasting
equipment. If you have not completed the Hog
Technologies basic training course you will be a
danger to yourself and others. The velocity of water
at the nozzle tip exceeds that of a bullet coming out
of a gun. Contact with the high pressure blast can
result in the loss of a limb or water injection into
the bloodstream. If injection occurs in a vulnerable
part of the body death may result.
Always Read Instructions
Read this manual and all other water blasting
equipment operation manuals and instructions prior
to using any Hog Technologies product. Contact
Hog Technologies (877-HOG ROAD) should any
questions arise.
Major Component Operation Manuals
The suppliers of some major components such as
engines, electric motors and pumps, provide their
own operation manuals which have been included
with your equipment. You should read the infor-
mation in this manual and the manuals of other
manufacturers completely and have a thorough
understanding of all component systems and their
proper operation before operating your equipment.
REMEMBER - IT IS YOUR RESPONSIBILITY
TO ENSURE THAT YOUR EQUIPMENT IS SAFE
FOR YOU AND YOUR CREW. ALWAYS EXER
-
CISE GOOD JUDGMENT WHEN INSTALLING
OR REPAIRING EQUIPMENT AND WHILE
OPERATING WATER BLASTING EQUIPMENT.
Work Area Safety
Remember, safety is first! Only set up to work in
areas properly protected from traffic and other
hazards. Individuals being struck by vehicles or
mobile equipment lead to many work zone fatali-
ties or injuries. Work zones need traffic controls
identified by signs, cones, barrels and barriers.
You should always wear high visibility clothing
with a fluorescent background and made of retro-
reflective material to be more visible to motorists
and reduce the possibility of an accident. Work
stations should always be illuminated.
Outfit all operators with proper safety apparel. Al
-
ways use eye protection to shield from projected
debris. Use ear protection to protect from noise
levels generated from pump, vacuum and water
blasting head. It is very important to wear steel
toed boots that provide good traction on slippery
surfaces.
Never wear loose clothing. Loose clothing can get
caught on moving or rotating parts causing serious
injury or even death.
Most ultra-high pressure water blasting operations
generate noise levels above 90 dB. Hearing protec-
tion is required in accordance with OSHA standards.
