Full title and description

ISO/TR 14294:2011 — Workplace atmospheres — Measurement of dermal exposure — Principles and methods. A technical report providing guidance and recommended practices for planning, selecting and validating methods to measure dermal (skin) exposure in occupational settings.

Abstract

ISO/TR 14294:2011 gives general considerations for assessing dermal exposure in the workplace. It describes commonly used approaches for measuring skin contamination, explains advantages and limitations of the different approaches, and sets out requirements and performance characteristics against which sampling and analytical methods should be evaluated (for example sampling efficiency, recovery, stability, capacity, bias, precision and uncertainty). The report is intended to help occupational hygiene practitioners and researchers develop consistent, fit‑for‑purpose dermal exposure assessment strategies but does not provide case‑specific expert advice on particular chemicals or exposure scenarios.

Scope

The report covers principles and methods for measuring dermal exposure in workplace atmospheres. It applies to planning dermal exposure assessments, selecting appropriate sampling and analytical approaches, and assessing method performance. It describes method performance requirements and recommends how to document core and contextual information needed to interpret results. ISO/TR 14294:2011 is aimed at practitioners and researchers; it is not a source of detailed toxicological or regulatory limits for specific chemicals.

Key topics and requirements

• Overview of approaches to measure dermal exposure (patch sampling, wipe sampling, hand washes, fluorescent tracers, biomonitoring linkages, surrogate measures).
• Criteria for method evaluation: sampling efficiency, recovery efficiency, sample stability and storage, capacity and saturation effects.
• Quantitative performance metrics: bias, precision and uncertainty assessment for dermal sampling methods.
• Specification of core and contextual information required with measurements (task description, exposed body parts, protective clothing, contact frequency, chemical form).
• Guidance on selecting methods to meet different assessment objectives and on validation and reporting of method performance.

Typical use and users

Used by occupational hygienists, exposure scientists, laboratory analysts, regulatory agencies, consultants and researchers who design or interpret dermal exposure assessments in workplaces (manufacturing, chemical processing, laboratories, healthcare, construction and similar settings). It supports method developers validating sampling/analysis techniques and employers or safety professionals planning exposure monitoring or control evaluations.

Related standards

Relevant complementary documents and standards include later ISO deliverables addressing dermal exposure assessment (for example ISO/TS 21623:2017 on dermal exposure assessment for nano‑objects and aggregates) and the developing ISO 13977 series (framework for dermal exposure assessment). National guidance on dermal exposure and occupational hygiene (for example from regulatory bodies and workplace safety agencies) is also commonly used alongside ISO/TR 14294.

FAQ

Q: What is this standard?

A: ISO/TR 14294:2011 is a Technical Report from ISO that provides principles and recommended methods for measuring dermal (skin) exposure in workplace environments.

Q: What does it cover?

A: It covers measurement approaches for dermal exposure, criteria and procedures for evaluating sampling/analytical methods (efficiency, recovery, stability, capacity, bias, precision, uncertainty), and the core/contextual information that should accompany dermal exposure data to support interpretation.

Q: Who typically uses it?

A: Occupational hygienists, exposure scientists, method developers, laboratory analysts, safety consultants, regulators and researchers involved in planning, performing or evaluating workplace dermal exposure assessments.

Q: Is it current or superseded?

A: As published in November 2011, ISO/TR 14294:2011 remains a published technical report. Users should check for newer ISO deliverables or national guidance when designing assessments—ISO work on dermal exposure (for example the ISO 13977 series and other technical specifications) has progressed since 2011 and may provide updated frameworks or additional parts.

Q: Is it part of a series?

A: ISO/TR 14294 is a standalone technical report focused on measurement principles and method evaluation. It is conceptually related to other ISO documents on dermal exposure and workplace exposure assessment (including technical specifications and later parts/standards under development that form a broader series addressing dermal exposure frameworks and specific applications).

Q: What are the key keywords?

A: Dermal exposure, skin sampling, occupational hygiene, sampling efficiency, method validation, workplace atmospheres, exposure assessment.
