Safety
CONTROL THE IGNITION SOURCE
a
Apply a “no smoking” policy in all
potentially hazardous areas.
b
Use only explosion-proof lights.
c
All welding and cutting is to take place
on the outside of the facility.
d
Properly lubricate bearings on all
equipment at the required intervals.
e
Use magnets to trap metal that might be
mixed in with the grain.
f
Check the lagging on bucket elevator
belt pulleys and belt conveyor pulleys
and replace lagging if any lagging is
worn or smooth.
g
Use recommended safety devices
such as heat detectors on bearings,
motion sensors on the boot shaft, belt
alignment sensors, or limit switches
to shut down the system if the leg is
choked. Make certain all electrical
wiring, lights, and outlets meet local
codes. (
DANGER! Do not “jog” a
choked leg.

GRAIN DUST EXPLOSION MYTHS
Throughout the years several myths have
surrounded grain dust explosions. These are
some of the most common:
a
Grain dust explosions do not occur in
times of high humidity.
False
: Dust explosions have occurred
during rain storms.
b
Grain dust explosions do not occur in
wooden elevators.
False
c
Grain dust explosions do not occur in
small country elevators.
False
: 70% - 80% of grain elevator
explosions occur in small country
terminals.
d
There are only (2) explosions that occur,
a primary and a secondary.
False
: Up to (13) explosions have been
documented during (1) incident.
EXPLOSION VENTING
Explosion vents for the trunking can be supplied
as optional equipment for all models of bucket
elevators. Explosion vents for heads are standard
on all SC models and optional on smaller units.
These vents, should an explosion occur within
a leg, may possibly minimize damage to the leg
and prevent a secondary explosion.
