Text For Citation: 01 Item/Group: 001 Hazard: UNAPEQUIP

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 serious burns from potential dust deflagration, explosion, or other fire hazards as the result of the improper design and maintenance dust collection system: (a)Oak-Dale Hardwood Products, Inc. in Spring Valley, WI: This employer has been previously cited for a violation of this occupational safety and health standard (under section 5(a)(1) of the Occupational Safety and Health Act of 1970), which was contained in OSHA inspection number 313175762, citation number one, item number one and was affirmed as a final order on 10/16/2009, with respect to the facility located at W121 2nd Street Spring Valley, WI. The following repeated deficiencies were found with the Honeyville Metal, Inc. bag house dust collector and associated systems used for collection of hardwood dusts: (1)A means of tramp metal protection was not provided to keep any unwanted metal fragments from entering the air-material separator (bag house). (2)A means of static charge dissipation, such as bonding or grounding was not provided between the air-material separator (bag house) and pieces of equipment which were connected by flexible non-metallic ductwork on machinery such as, but not limited to, the IMC straight line rip saw, Northfield radial arm saw, and the Medalist double end tenoner. (3)Use of flexible non-metallic ductwork exceeded the minimum required for machinery operation on equipment such as, but not limited to, the Northfield radial arm saw and the Medalist double end tenoner. (4)A deflagration isolation or suppression system was not provided between the inlet (dirty air) side of the air-material separator (bag house) and the facility itself. (5)A spark detection system with high speed abort gate or extinguishment capability was not installed downstream of the last material entry points and upstream of the air-material separator (bag house) where machinery having a history of producing sparks, including a large belt sander having an automatic feed system (Duramac wide belt sander), was used. Abatement note: Abatement certification and documentation are required for this item. Although not determined to be a hazard upon inspection on 10/27/2010 due to the previous recommendation of interim measures, under inspection 313175762, the employer had diverted the clean air return ductwork to the outside atmosphere until the required engineering abatement could be installed. The requirements of NFPA 664 (2007) Section 8.2.2.6 shall be referenced regarding the requirements for safely recyclingexhausted air and Section 8.2.4 regarding deflagration isolation of the return air (outlet) side from the facility. Abatement Schedule STEP 1- A written, detailed plan of abatement shall be submitted to the Area Director outlining a schedule for the implementation of engineering and/or administrative measures to control employee exposures to the hazardous condition referenced in this citation. This plan shall include, at a minimum, target dates for the following actions which must be consistent with the abatement dates required by this citation: (1)Evaluation of engineering/administrative control options; (2)Selection of optimum control methods and completion of design; (3)Procurement, installation and operation of selected measures; (4)Testing and acceptance or modification/redesign of controls; All proposed measures shall be approved for each particular use by a competent certified safety professional, professional engineer, or other technically qualified person.
