Monitoring the control of exposure to hazardous substances

Monitoring means measuring to show that control is adequate. It has nothing to do with the state of a worker's health.

When do you need to monitor?

Monitoring is appropriate:

Monitoring can also indicate the spread of contamination, eg surface wipes.

Screening, eg colorimetric detector tubes, meters, provides indicators of worker exposure only.

Personal air monitoring measures how much of a substance the worker inhales.

Biological monitoring measures how much of a substance has entered the body.
