A study protocol was developed to obtain simulated workplace protection factor (SWPF) data for eleven models of powered air-purifying respirators (PAPRs) and supplied-air respirators (SAR) with hoods and helmets. Respirators were tested in a chamber

The current practice for the determination of personal exposures to airborne dusts involves the aspiration of known quantities of air through membrane filters held in filter holders. The two-piece, 37-mm polystyrene cassette is the most typically use

A sampling and analytical method for the measurement of hydrazoic acid (HN3) at the short-term ceiling limit was developed and validated under both laboratory and field conditions. The HN3 was collected on sodium hydroxide pretreated Orbo 52 silica g

The Occupational Safety and Health Administration (OSHA) set a 5-ppm excursion limit (EL) for ethylene oxide (EtO) in April 1988. Both active and passive sampling methods have been proposed for monitoring workers against this new standard. Passive do

An exposure and analysis protocol is described for the field validation of passive dosimeters for ethylene oxide (EtO) excursion limit monitoring. The protocol calls for the use of a field exposure chamber with concurrent sampling using Tedlar air-sa

In the comparison of metals in the hair, blood, and urine of 100 acculturated and 90 unacculturated individuals copper level was found to be the same in both groups. Levels of lead and cadmium were found to be markedly lower in the unacculturated pop

Passive dosimetry has considerable advantages over active sampling for monitoring exposures to ethylene oxide (EtO), including reduced complexity, reduced cost, and increased sample stability. The major disadvantage of these methods is the conflictin
