Aiha Exposure Assessment Strategy
v2.0Use when a Certified Industrial Hygienist (CIH), Registered Occupational Hygienist (ROH), Certified Safety Professional (CSP), industrial hygienist in training, or EHS manager needs to draft an AIHA-aligned occupational exposure assessment strategy for a workplace, process, task, or Similar Exposure Group (SEG) — aligned to AIHA *A Strategy for Assessing and Managing Occupational Exposures, 4th Ed.*, AIHA *Principles of Good Practice* §2, ACGIH TLV / NIOSH REL / OSHA PEL / AIHA WEEL / OARS, OSHA 29 CFR 1910 General Industry or 29 CFR 1926 Construction or MSHA 30 CFR Parts 56 / 57 / 58, and the AIHA-CP / ANSI/ASSP Z10 / ISO 45001 management-system frame. Guides scoped intake of site, scope, regulatory frame, basic characterization (workplace / workforce / agents / tasks / controls / prior data), agent inventory with OEL source per agent, SEG construction using the AIHA 4-dimension rule, qualitative AIHA 0–4 exposure rating with uncertainty rating before any sampling, quantitative sampling plan with n / method / media / QA-QC / laboratory accreditation, statistical analysis plan (GM, GSD, UTL_95%,95%, 95% UCL on the 95th percentile, exceedance fraction, lognormality test, Bayesian Decision Analysis option), exposure judgement against the controlling OEL, reanalysis trigger schedule per AIHA rating, corrective-action recommendations in hierarchy-of-controls order, and Management-of-Change trigger list, and produces a DRAFT strategy with an unsigned CIH / ROH / CSP review block, evidence index, and unresolved-questions list — for licensed industrial-hygiene review before respiratory-protection-program, control-banding, or control-design decisions. Never substitutes for the CIH of record, never authorizes a respirator-required SEG, never selects a respirator cartridge, never declares an SEG "Acceptable" without statistical evidence on the controlling OEL, never merges SEGs across different agents / control regimes / shift lengths, and never substitutes a single-point comparison for the AIHA statistical test set.
