Text For Citation: 01 Item/Group: 001 Hazard: EXPLOSION
40.1-51.1.(a): The employer did not furnish employment and a place of employment which were free from recognized hazards that were causing or likely to cause death or serious physical harm to employees in that employees were exposed to fire from an explosion in Silo #1 causing severe burns to four employees on 4/24/99. Feasible and acceptable abatement methods, among other things to correct this hazard is: a. to eliminate employee exposure to the outfeed chute, and other potential openings or hatches, where a dust explosion/deflagration could vent while a fire in the silo is being suppressed; and b. through the operation of an effective spark extinguishing system meeting the requirements of NFPA 69 (1986) - Explosion Prevention Systems: i. Ensure that "Spacing between a detector and the extinguishing agent injection point shall be based on the linear velocity of the material in the duct and the response time of the detector and the actuator circuitry". (NFPA 69 - 1986 Section 6-3.1.1) ii. Ensure that "The extinguishing agent supply system shall be capable of supplying all discharge nozzles at the rated volume and pressure." (NFPA 69 - 1986 section 6-3.1.1) iii. Ensure that "The numbers of detectors shall be sufficient to detect a glowing particle at any location in the cross- sectional area of the duct." (NFPA - 1986 section 6-3.1.2)
