Welding:
Open flame or sparks near wood debris, oils,
fuel, or pressurized gases are an obvious source of igni-
tion. Welding or torch cutting can be especially hazard-
ous in an environment where woody materials are being
reduced to small particles. While your hood or goggles
are on, you may miss the smoke and not notice the fire
until it is large. Always follow your worksite’s Hot
Work Procedures.
Smoking:
Smoking tobacco in the grinding area is
high risk behavior. Carelessness can quickly lead to
disaster. Peterson recommends a no-smoking policy
near the grinders.
Hydraulic Leaks:
Replace worn or leaky hydraulic
hoses, worn or missing hose sleeves, and fuel lines.
Take notice of pin-hole sized hydraulic or fuel leaks that
may spray a fine mist of oil or fuel near a heat source.
This is a highly flammable condition that operators and
maintenance personnel must avoid.
Mufflers:
Maintain the muffler and exhaust system to
keep sparks from flying out the stack. Regularly inspect
the muffler and exhaust system for rust spots and leaks.
Replace worn parts as needed to prevent sparks from
escaping.
Diesel Fuel Vapors: :
Diesel fuel vapors are present
in a fuel tank, in a container, near leaking or spraying
diesel fuel, or near a spill of diesel fuel. Diesel fuel gen-
erates vapors at temperatures above 100°F (38°C). Die-
sel vapors can burn or explode at ratios of 0.5% to 7%
with air if exposed to an ignition source.
Ignition sources include any activity which would cre-
ate flames, sparks, electrical arcing, or very hot sur-
faces. Keep flames or other ignition sources away from
diesel fuel. Replace damaged fuel tanks.
Spontaneous Combustion:
Wood particles com-
bined with oils or greases can burn spontaneously. As
accumulations increase in depth, the likelihood of spon-
taneous combustion increases.

WARNING
Fire hazard.
Fires can start in combustible materials around
the machine many hours after it has been shut
down. If the machine is left unattended after
shutdown, make certain that it is not near com-
bustible or flammable materials.
Fire Suppression Equipment
Keep Class ABC fire extinguishers (intended for diesel
fuel or wood fires), water trucks, water pump sprayers,
and other fire suppression systems maintained in good
operating condition and near the machine at all times.
Fire Extinguisher
The red fire extinguisher shipped with the machine is
mounted on the frame (Figure 37). Inspect and recharge
the extinguisher annually. Pressure test it as required.

Location for Class A,B,C Fire Extinguisher
Water Pump Sprayer
The electric-powered, water pump sprayer system can
help prevent fires and keep the machine clean of dust
and debris, which contribute to machine fires.
The frame-mounted tank (Figure 38) supplies the water
through a hose and nozzle attached to the water pump
(Figure 39).
