Text For Citation: 01 Item/Group: 003 Hazard: DUST&FUMES

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: the employees were exposed to explosion and deflagration hazards. a) Trim Booth Ventilation- On and before 1/11/11- Exhaust ventilation to capture Hazardous Air Particles (HAP) which was explosive in nature was insufficient. The indoor dust collector was not adequately sized, was not equipped with explosion protection with deflagration venting to the outside. Among other methods, feasible and acceptable methods to correct these hazards are: 1.) Have a qualified engineer inspect the dust collectors to evaluate the design and installation in accordance with National Fire Protection (NFPA) 654, Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids and make necessary modifications. 2.) Equip the dust collection system with explosion proof venting to the outside of the building. ABATEMENT DOCUMENTATION AND CERTIFICATION IS REQUIRED FOR THIS ITEM NFPA 654 Chapter 6 Facility and Systems Design 6.1 General. The provisions of this section shall apply to the overall design of systems that handle combustible particulate solids. 6.1.1* Those portions of the process and facility where a dust deflagration hazard exists shall be protected from the effects of dust deflagrations in accordance with Sections 6.2, 6.3, and 6.4 Chapter 7 Process Equipment 7.1* General. Methods of fire and explosion protection for specific equipment shall be in accordance with this section. Chapter 8.1.1 requires "Continuous suction to minimize the escape of dust shall be provided for processes where combustible dust is liberated in normal operation". The existing dust collection system actually maximizes the escape of dust throughout the space and Dust Chamber. The dust should be collected closer to the point of generation. Chapter 8.1.2 requires "dust shall be conveyed to dust collectors". The employer is actually using the Trimming Booth itself to convey the dust to the Dust Chamber collector. The room cannot be used as a method of conveyance. The indoor dust collector system was not adequately sized, equipped with deflagration protection and was not vented to the outside.
