With video exposure monitoring (VEM), worker exposures to lead are monitored and recorded with a direct reading instrument. At the same time, work place activities are recorded on a video tape. The right hand bar indicates changes in total dust concentrations over time.

As the employee removes the protective gloves, the increasing red bar indicates that the employee is exposed to lead due to dispersion of lead from the surface of the improperly cleaned or stored gloves.

With video exposure monitoring (VEM), worker exposures to lead are monitored and recorded with a direct reading instrument. At the same time, work place activities are recorded on a video tape. The right hand bar indicates changes in total dust concentrations over time.

As the employee shovels the slag during cleanup and places it into the slag pot for disposal, the increasing red bar indicates that the employee is exposed because lead dust is inadequately captured when the slag is shoveled and dumped into the pot.
