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 the bucket elevator head pulley and replace it if it 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 one 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.
