Section 5(a)(1) of the Occupational Safety and Health Act of 1970: 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 combustible protein powder mixture deflagration, explosion, or other fire hazards as a result of working at or near multiple indoor cartridge media-type dust collectors lacking means to prevent employee or minimize employee exposure in the event of an explosion, deflagration, or other uncontrolled fire event.       a. The Donaldson Torit Downflo II cartridge media-type dust collector servicing the Room 3 filling line #9 was located indoors within Production Room 2.  The collector lacked means of 1) explosion protection and 2) deflagration propagation protection (isolation) for upstream and downstream ducting/equipment and the discharge drum.  The collector also returned filtered air back into the building (Production Room 3) without means to prevent the transmission of smoke and flame from a fire or flame front and pressure effects from an internal deflagration.       b. The two Donaldson Torit Downflo II cartridge media-type dust collectors servicing the Room 1 blending operations were located indoors within Production Room 2.  The collectors lacked means of 1) explosion protection and 2) deflagration propagation protection (isolation) for upstream and downstream ducting/equipment and discharge drums.  The collectors also returned filtered air back into the building (Production Room 1) without means to prevent the transmission of smoke and flame from a fire or flame front and pressure effects from an internal deflagration.       c.  The Donaldson Torit Downflo II cartridge media-type dust collector servicing the Room 2 filling lines #s 1-4 was located indoors within Production Room 2.  The collector lacked means of 1) explosion protection and 2) deflagration propagation protection (isolation) for upstream and downstream ducting/equipment and the discharge drum.  The collector also returned filtered air back into the building (Production Room 2) without means to prevent the transmission of smoke and flame from a fire or flame front and pressure effects from an internal deflagration.   Abatement documentation is required for this item in accordance with the requirements of 29 CFR 1903.19(d).
