Slide 3 of 15

In selecting an exposure assessment strategy, there are several issues that could be considered:

Sufficiency - How much monitoring is required To represent the conditions properly To ensure we have included the right people For future needs - such as building worker exposure histories

Sample Selection - Which workers or conditions should be sampled to meet these needs.

Reliability - What assurances do we have that the exposure records are accurate, representative and repeatable? How do we avoid artifact?

Recordkeeping - Do the samples contain necessary information for future situations that may arise?

Exposure Control - Is the protocol designed to identify sources and worker interaction? Will it help in our engineering program?

Utility - Does the sampling method promote meaningful information useful for engineers, medical/safety personnel, management & workers?

Cost Effectiveness - Given the desired level of reliability, precision and documentation what is the most effective way to meet those needs?
