• Traditional exposure assessment: integrated sampling in the personal breathing zone (PBZ) of a worker over a specified period of time:

• air drawn through a filter or other collection medium

• known flow rate by means of a battery powered pump

• measured period of time

• medium is analyzed 

• average exposure during the sampling period is computed

HOWEVER…

• Integrated air sampling provides little insight into the specific causes of the worker's exposure

• Recommendations for controlling exposures:

• often based upon an observer's judgment

• can result in implementation of control measures that do not address the major worker air contaminant exposure sources

• Direct reading instruments and data recording devices can be used as a part of a system for data‐logging events and exposures in the workplace as a function of time. 

• The data can be used to:

• Show rapid changes in concentrations of contaminants in air• Associate events/activities and exposures• Promote more effective and focused recommendations for 

controlling the air contaminant exposures

• Obvious need: best ways to communicate exposure assessment results to workers and to management?

• a video recording of the work activity combined with a display of the real‐time exposure measurement

• the data could be presented in two forms:1. numerically2. graphically

• Disadvantages in past:• Video and sampling 

equipment cumbersome and large

• Output limited because of direct overlay of data onto video

• Advantages currently:• Miniaturization of sampling 

and video equipment• Video and sampling data in 

digital format • Prompted software 

development

The Enhanced Video Analysis of Dust Exposures (EVADE) software program merges video files and logged data files, allowing the user to view them simultaneously to help identify exposure sources.

New features for EVADE 2.0 Beta include:

• Expansion beyond just dust exposure

• Multiple channels• Advanced windowing interface• Redesigned project editor• Share a project• Basic data analyses• Improved installation program

Pointer to Remember when using EVADE:

• Timing is crucial!• Start video camera and logging equipment simultaneously• Ensure internal clocks of equipment are identical• Collect second‐by‐second data for exposures

• File formats: • .avi (or) .mp4  [movies]• .csv (comma separated value) [exposure data logged file]

• Consider job tasks involved and need for intrinsically safe equipment

• Camera battery life likely no greater than 2–4 hours 

• Great training tool!
