Text For Citation: 01 Item/Group: 001 Hazard: STRUCK BY
5(a)(1): 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 possible injuries resulting from fire and explosion from aluminum dust generated during the aluminum coating operation at the tube mill: a) On 9/11/2005 employees at the tube mill were provided with a steel scraper to be used for cleaning aluminum dust from the interior of the arc spraying enclosure; use of this scraper could cause sparks resulting in ignition of aluminum dust. b) The exhaust system used to remove dust from the aluminum coating enclosure had drop legs which were capped extensions connected to the ceiling mounted exhaust duct. Behind the tube mill one of these drop legs reached to the floor, another was located near the exterior building wall. These duct sections can trap the combustible aluminum dust and cause an explosion. c) The enclosure and the duct work were constructed of steel and galvanized steel respectively. These materials can spark if they become corroded or if they are struck by other materials. One feasible method of abatement of this hazard is to comply with applicable standards issued by the National Fire Protection Association (NFPA) and the Aluminum Industry Association: NFPA 484, 2006 Edition section 6.2.3.3 and 6.5.7.3.3 states that spark resistant tools should be used for cleaning purposes. Section 6.3.3.5.2 states that there shall be no unused capped outlets or other dead-end spaces in the ducts that could allow for accumulations of dust. The Aluminum Industry Association, standard F, Guideline for Handling Aluminum Fines Generated During Various Aluminum Fabricating Operations states that hoods, enclosures and ducts should be rustproof, non- sparking metal.
