![]() So temperatures can climb quite high and combustion may occur. The silage surroundingĪn area with excessive heat generation acts as insulation, Of oxygen may allow the microorganisms to reproduce too rapidlyĪnd generate heat faster than normal. Produce a certain amount of heat, thus silage will be fairly ![]() The bacteria responsible for fermentation ![]() Is formed when forage crops are allowed to ferment in theĪbsence of air. Poor distribution of materialĭuring filling may result in poor compaction and contribute Air enters the silo through cracks in the walls The leadingĬause of this type fire is low moisture silage and air leaks Spontaneous ignition within the stored silage. More troublesome fires, however, are those resulting from Of the silo unloader will extend the service life of the equipmentĪnd reduce potential for fire. Problems, overheated bearings and slipping belts can igniteĭust and dry materials on the equipment. Of course, the best way of dealing withĪ few silo fires are caused by unloading equipment. Know what the hazards areĪnd act accordingly. Or glowing red silage, smoke pouring out of the silo or a Often, the first sign of fire is a piece of burnedĭoor that falls down the chute. Of conditions are possible when fires are in conventional Aįew have resulted in raging fires or explosions, some with That become a frustration to farmers and fire fighters.

Note to paragraph (g)(2): When the employee is standing or walking on a surface which the employer demonstrates is free from engulfment hazards, the lifeline or alternative means may be disconnected or removed.Manual was prepared to inform Tennessee farmers and firefightersĪbout causes, prevention and control of silo fires. Exception: Where the employer can demonstrate that the protection required by this paragraph is not feasible or creates a greater hazard, the employer shall provide an alternative means of protection which is demonstrated to prevent the employee from sinking further than waist-deep in the grain. The lifeline shall be so positioned, and of sufficient length, to prevent the employee from sinking further than waist-deep in the grain. Whenever an employee enters a grain storage structure from a level at or above the level of the stored grain or grain products, or whenever an employee walks or stands on or in stored grain of a depth which poses an engulfment hazard, the employer shall equip the employee with a body harness with lifeline, or a boatswain's chair that meets the requirements of subpart D of this part. Permit means the written certification by the employer authorizing employees to perform identified work operations subject to specified precautions. Lagging means a covering on drive pulleys used to increase the coefficient of friction between the pulley and the belt. Jogging means repeated starting and stopping of drive motors in an attempt to clear choked legs. Bucket elevators with leg casings that are inside (and pass through the roofs) of rail or truck dump sheds with the remainder of the leg outside of the grain elevator structure, are not considered inside bucket elevators. Inside bucket elevator means a bucket elevator that has the boot and more than 20 percent of the total leg height (above grade or ground level) inside the grain elevator structure. Hot work means work involving electric or gas welding, cutting, brazing, or similar flame producing operations. Grain elevator means a facility engaged in the receipt, handling, storage, and shipment of bulk raw agricultural commodities such as corn, wheat, oats, barley, sunflower seeds, and soybeans. Standard 40 mesh sieve (425 microns or less). A bucket elevator is not considered choked that has the up-leg partially or fully loaded and has the boot and discharge cleared allowing bucket movement.įlat storage structure means a grain storage building or structure that will not empty completely by gravity, has an unrestricted ground level opening for entry, and must be entered to reclaim the residual grain using powered equipment or manual means.įugitive grain dust means combustible dust particles, emitted from the stock handling system, of such size as will pass through a U.S. ![]() Choked leg means a condition of material buildup in the bucket elevator that results in the stoppage of material flow and bucket movement.
