The Donaldson Torit Model VS1200 dust collection system provided was not designed and installed to be used with combustible metal dust. </li></ul><ul><li>Specifically: </li></ul><ul><ul><li>The collection hood provided at the de-burring workstation was not designed and maintained so that fine particles would either fall or be projected in the direction of airflow . (NFPA 484, Section 6.3.2.2) </li></ul></ul><ul><ul><li>The dry-type dust collector was located inside of the building. (NFPA 484, Section 6.3.2.5) </li></ul></ul><ul><ul><li>The dust collection system was not dedicated to the collection of aluminum or aluminum alloy dust .

(NFPA 484, Section 6.3.2.6) </li></ul></ul><ul><ul><li>The plastic hose that connected the exhaust hood to the dust collector was not short, straight, conductive and provided with a smooth interior surface , factors required to maximize free air flow and minimize accumulations of combustible dust inside the ductwork. (NFPA 484, Sections 6.3.3.4, & 6.3.3.5.1 & 10.4.4.2) </li></ul></ul><ul><ul><li>The pneumatic hand tools provided for use were not interlocked with the dust collector to ensure that the dust collector was on and properly functioning before deburring operations commenced. Also, a time delay switch or equivalent device was not provided on the dust collector to prevent hand tools from starting until the dust collector was in full operation.

The Donaldson Torit Vibra Shake dust collector contained dry fabric-type collection media . (NFPA, Section 10.4.8.1) </li></ul></ul><ul><li>Among other methods, one feasible and acceptable abatement method to correct this hazard is to design and install a dust collection system that complies with generally accepted guidelines such as National Fire Protection Association (NFPA) Standard 484 Standard for Combustible Metals. </li></ul>Air Handling Systems - Copyright 2011 For informational use only
