Beryllium Sensitization Algorithm (current until revisions to 10 CFR 850 are passed): An employee is considered sensitized if any one of the following clinical criteria and incidence rules for the case definition of beryllium sensitizations is met. Often, an employee’s data will satisfy multiple criteria, and their date of sensitization is calculated as the earliest date any one of these is met.

  • 2 positive or abnormal BELPT results (based on 2 separate blood draws).
  • 1 positive or abnormal plus 2 (or more) borderline BELPT results.
  • A positive or abnormal bronchoalveolar lavage (BAL) result.
  • A CBD evaluation with a finding of sensitization but no chronic beryllium disease (CBD).

Exposure Monitoring Statistics: These calculations are based on the methods described in the Statistical Methods and Software for the Analysis of Occupational Exposure Data with Non-Detectable Values. Due to the limitations in laboratory analytic methods approaching nano- scales much of the airborne exposure monitoring data are subject to left censoring with a measurement below the detectable limit. The methods applied estimate non-detectable levels using maximum likelihoods for randomly left censored, lognormal data with alternative non-parametric methods applied when the lognormal distribution is in doubt due to small sample sizes.

Pearson Product-Moment Correlation Coefficient: The Pearson Product-Moment Correlation Coefficient monitors the dose response represented by the BAWR data, and is calculated by site with the percent exceeding the action level and the percent beryllium sensitized or diagnosed with CBD.
