Personal Passive Monitors for Chemical Agents

摘要

Small lightweight passive personal monitoring devices for chemicals such as sulfur-dioxide (7446095) and mercury (7439976) are discussed. Such monitors function by diffusion and permeation and are worn on the collar, lapel, or pocket by the worker. Some register single and some record multiple chemicals. Some give measurements at work, while others require laboratory analysis. Ten inorganic, five organic, and two general monitors are described. Response, such as alarm or color change, the particular laboratory analysis, the recommended exposure limits, the collection mechanism, and the manufacturer are presented. The authors conclude that interfering compounds in the atmosphere make it important to determine which device will best protect the health of the workers by its accuracy.
