by jbs051809h3 — May 20, 2009—The U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA) is initiating a comprehensive rulemaking on combustible dust. OSHA will issue an Advanced Notice of Proposed Rulemaking and convene related stakeholder meetings to evaluate possible regulatory methods, and request data and comments on issues related to combustible dust such as hazard recognition, assessment, communication, defining combustible dust, and other concerns.
Since 1980, more than 130 workers have been killed and more than 780 injured in combustible dust explosions, explains OSHA. These include 14 people who were killed in a dust explosion February 7, 2008, at an Imperial Sugar Co. plant in Georgia and three workers who were burned in April 2009 in an Illinois pet food plant dust explosion.
OSHA defines combustible dusts as solids finely ground into fine particles, fibers, chips, chunks or flakes that can cause a fire or explosion when suspended in air under certain conditions. Types of dusts include metal (aluminum and magnesium), wood, plastic or rubber, coal, flour, sugar, and paper, among others.
In 2006, the U.S. Chemical Safety Board (CSB) recommended that OSHA issue a combustible dust standard. OSHA received additional support for a combustible dust standard from the CSB during a congressional hearing in 2008 when the board said a new standard, combined with enforcement and education, could save workers’ lives.
