Safer Healthier Workers


Buy Quiet

Categories: Engineering Control, Hearing Loss, Manufacturing, Prevention Through Design

a circular sawWe know that using tools and machinery that produce less noise will help prevent hearing loss among the workers who use them. The next step would seem obvious—buy quieter tools and machinery. Unfortunately, it’s not that simple. Making products quieter is a tough sell in industry. Currently, the availability of quieter tools and machines is limited and it’s not always clear to purchasers how much noise particular tools and machinery produce. NIOSH and its partners are working to change that through the creation of a Buy Quiet web tool.

This web tool will build on the process of “buy quiet”—the concept that employers can most effectively reduce hazardous noise levels at their worksites through their procurement process.

The Continuing Persistence of Silicosis

The Occupational Safety and Health Administration (OSHA) estimated in 2003 that over 2 million workers were potentially exposed to crystalline silica dust in general industry, construction and maritime industries. Based on OSHA compliance inspection data, Yassin et al estimated that about 119,000 of such workers were exposed. Inhalation of crystalline silica can cause silicosis, a preventable but incurable type of lung fibrosis. At current U.S. levels of exposure, chronic inhalation generally takes a decade or longer to cause disease. However, high levels of exposure can cause disease more quickly. Severe cases can be disabling or even fatal. Breathing silica dust is also associated with tuberculosis, lung cancer, and chronic obstructive pulmonary disease (COPD). Exposure to silica dust may also cause various autoimmune diseases and chronic renal (kidney) disease.

Bed Bugs!

The article reported on a resurgence of reports about infestations of tiny Cimex lectularius in New York City. These “stealthy and fast-moving nocturnal creatures that were all but eradicated by DDT after World War II, have recently been found in hospital maternity wards, private schools and even a plastic surgeon’s waiting room,” the article stated.1

The New York experience is not unique. Around the world, pest control specialists have reported “10-fold, 100-fold, even 1,000-fold increases in bed bug jobs over the past five or ten years,” according to pest control consultants Lawrence J. Pinto, Richard Cooper, and Sandy Kraft.2

Prevention through Design Standard

Categories: Engineering Control, Manufacturing, Policy and Programs, Prevention Through Design

PtD logoThe American Society of Safety Engineers (ASSE) recently announced the approval of the American National Standards Institute (ANSI)/ASSE standard, “Prevention through Design: Guidelines for Addressing Occupational Risks in Design and Redesign Processes” (Z590.3). This new standard provides guidance on including Prevention through Design concepts within an occupational safety and health management system, and can be applied in any occupational setting.

The new standard focuses specifically on the avoidance, elimination, reduction and control of occupational safety and health hazards and risks in the design and redesign process. Through the application of the concepts presented in the standard, decisions about occupational hazards and risks can be incorporated into the process of design and redesign of work areas, tools, equipment, machinery, substances and work processes.
