~~~~~~~~~~~~~~~~~~~~~~~
Guidelines to Minimize Grain Dust
Explosion Conditions
1. Maintain a rigorous housekeeping and sanitation program
inside the grain elevator structure. Keep grain dust cleaned
up in all working areas of the elevator.
2. Implement a weekly or bi-weekly (or as specified by the
manufacturer) bearing lubrication program, based on the
bearing manufacturer’s specifications.
3. Use a food-grade mineral oil spray system on grain during
transfer and loadout.
4. Install bearing temperature monitors on leg boot, head,
and knee pulley shafts, on horizontal drag head and
boot bearings, and on belt conveyor drive and idler
bearings.
5. Install belt rub sensors inside bucket elevator leg casings
to detect belt misalignment to prevent friction heating.
6. Maintain a periodic (weekly or bi-weekly) bearing tem-
perature monitoring program. Document periodic bear-
ing temperature readings and compare with previous
readings. A substantial bearing temperature increase
(10 F to 20 F or more in a week or two) may indicate
bearing failure and the need to replace the bearing.
7. Replace steel cups with plastic cups in elevator legs.
8. Use anti-static belting material in legs and horizontal belt
conveyors.
9. Install quick-opening cleanout doors on leg boot side
panels for grain and dust cleanout.
10. Install dust aspiration systems at grain transfer points or
ventilation systems in tunnels and galleries with open
conveyors, and truck dump pits where dust accumulation
is a problem.
11. Install dust aspiration or suction ventilation systems on
inside enclosed legs and conveyors to keep suspended
dust below MEC levels.
12. Clean out dust collectors and change filter bags at intervals
recommended by the manufacturer.
13. Clean out dust cyclone collector holding bins at scheduled
intervals.
14. Install dump pit baffles on truck dump pits to provide a
major reduction in airborne dust during dumping operation.
15. Incorporate explosion relief panels and devices in elevator
design
16. Install explosion proof electrical outlets and equipment in
sensitive areas.
17. Train employees on the dangers and prevention of dust
explosions.
