When effective engineering controls and work practice control measures are not feasible, or while they are being implemented or evaluated, respiratory protection may be required to achieve this objective.
In this case, it does much more than merely hurt. “This case” refers to last Thursday’s (October 24, 2013) rather extraordinary admission by OSHA chief Dr. David Michaels that hundreds of OSHA’s permissible exposures limits (PELs) are far out of date, basically useless, and in fact dangerous.
The American Chemistry Council (ACC) is taking issue with an online tool developed by OSHA to help employers assess the relative safety of potential alternatives for hazardous chemicals. While the ACC said it welcomed OSHA’s recent launch of a website making it easier to access up-to-date information on Permissible Exposure Limits (PELs) for the workplace, it feels more input is needed.
The better our understanding of exposures and the risks they pose, the more assurance we have that we are controlling the most important (highest risk) exposures first. Control efforts (such as engineering, work practice, or personal protective equipment) are often costly to implement and maintain.
Exposure to oil, dispersants heightens cancer risk
October 2, 2013
Researchers studying a small sampling of workers who’d helped clean up the 2010 Gulf of Mexico oil spill found significantly altered blood profiles that could indicate an increased risk of certain kinds of cancer.
NIOSH is currently testing low-cost solutions for protecting workers from silica exposure when cutting fiber cement siding. You can help us test a dust control and at the same time add to the research that supports and advances the prevention of silicosis.
Low levels of two common metals may contribute to hearing loss, according to a study published recently in Environmental Health Perspectives. Researchers found that lead and cadmium – even at levels below national workplace standards set by OSHA – can damage hearing.
In the movie “Zero Dark Thirty” a brief exchange occurs between a CIA subordinate and his boss at Langley HQ. The subordinate and his team are frustrated. The higher-ups are not with aggression pursuing leads that the team believes could track down Bin Laden. “I wonder,” says the subordinate. “how do you assess the risk of doing nothing?”
A new study, funded by the Canadian Cancer Society, will examine the human and economic impact of workplace exposure to 44 known or suspected carcinogens and their links to 27 types of cancer. The study's main goals are to quantify - for the first time - how serious the problem is in Canada by estimating the number of new cancer cases and cancer deaths that can be attributed to workplace factors, and also to weigh the economic impact.
