When you purchase a product, you expect it to work. Construction workers on high-rise buildings need to be confident that their safety harnesses will arrest a fall. Firefighters need to know that their gloves and other protective equipment can withstand high temperatures. Healthcare workers administering highly toxic chemotherapy agents need to know that their gloves will withstand penetration. For personal protective technologies (PPT)-where the major purpose of the product is to protect the wearer against a hazard-a deficit in product effectiveness can mean injury, illness, or death. Examining the extent to which products meet specific performance or design criteria is the focus of conformity assessment efforts. For PPT conformity assessment, the ultimate goal is preventing worker illness, injury, or death from hazardous working conditions. Certifying Personal Protective Technologies focuses on conformity assessment for occupational PPT-ensuring that PPT are effective in preventing or reducing hazardous exposures or situations that workers face in their jobs. Because respirators already have an extensive testing and conformity assessment process in place, this book specifically addresses conformity assessment processes for other types of PPT, including eye and face protection, gloves, hearing protectors, and protective clothing.

Popular culture often equates testosterone with virility, strength, and the macho male physique. Viewed by some as an a /antiaging tonic,a testosteronea (TM)s reputation and increased use by men of all ages in the United States have outpaced the scientific evidence about its potential benefits and risks. In particular there has been growing concern about an increase in the number of middle-aged and older men using testosterone and the lack of scientific data on the effect it may have on aging males. Studies of testosterone replacement therapy in older men have generally been of short duration, involving small numbers of participants and often lacking adequate controls. Testosterone and Aging weighs the options of future research directions, examines the risks and benefits of testosterone replacement therapy, assesses the potential public health impact of such therapy in the United States, and considers ethical issues related to the conduct of clinical trials. Testosterone therapy remains an attractive option to many men even as speculation abounds regarding its potential.
