Bodies, identification personal effect

Each situation requires an evaluation of the hypotheses to be tested before the personal monitor can be designed and the identification of the types and duration of exposure that may occur. Once inhaled, the compound may be rapidly metabolized in the body short-term measurements would be appropriate for such processes. The compound may instead have a long residence time at a specific site in the lung or may be stored in an organ or tissue. Thus, the inhaled compound or one or more of its adducts or metabolites could eventually deliver a biologically effective dose to a target organ or cell (13). The monitor must be developed with consideration of the... 

Patches are essentially spot or grab samples (typically 25 cm ) of the skin, whereby dermal exposure is assessed by extrapolating the patch loading level to the surface of the entire body. Given that only a small area of exposed skin is covered by the patches used, the uncertainties in calculating true exposure are likely to be high. Furthermore, the exposure pattern may vary with time, with activities, and both within and between individuals, days and shifts. However, several field studies have shown that this technique is a useful tool in the identification and evaluation of dermal exposures to a range of workplace contaminants and in the assessment of the effectiveness of personal protective equipment (Fenske et al. 1990). 

Numerous security devices may reduce the risk for assaults against workers and facilitate the identification and apprehension of perpetrators. These include closed-circuit cameras, alarms, two-way mirrors, card-key access systems, panic-bar doors locked from the outside only, and trouble lights or geographic locating devices in taxicabs and other mobile workplaces. Personal protective equipment such as body armor has been used effectively by public safety personnel to mitigate the effects of workplace violence. For example, the lives of more than 1800 police officers have been saved by Kevlar vests.
