Overview
ISO 16073-2:2019 defines minimum performance requirements and test methods for assessing compatibility of wildland firefighting personal protective equipment (PPE). It ensures that items worn together as an ensemble - clothing, helmets, gloves, footwear, face/eye protection, hearing protection and firehoods - fit and function without impairing protection or mobility during extended wildland firefighting operations. The standard excludes structural firefighting PPE, CBRN protection and garments requiring reflective outer surfaces.
Key topics and requirements
- Compatibility definition: Addresses interference between different PPE items that could reduce protection or restrict use.
- Performance baseline: Compatible items must meet the relevant requirements of ISO/TS 11999-2 (practical performance/compatibility tests).
- Fit and function testing: Practical performance tests (as referenced from ISO/TS 11999-2) that demonstrate fit, interface and functional interaction of PPE components.
- Test subjects:
- Minimum of three trained test subjects (at least one male and one female) for basic testing.
- For statistical testing a minimum of six subjects; to evaluate gender aspects, 12 subjects (6 male, 6 female) are recommended.
- PPE must be appropriate size and correctly fitted for each subject.
- Test conditions: Tests must reflect realistic use environments; at least one test in dry ambient conditions is required.
- Reporting: Test reports shall document ensembles tested and note any points of incompatibility.
- User guidance: Emphasizes manufacturer marking and instructions (see ISO 16073-1) and the need for firefighter training and risk assessment.
Practical applications
- Manufacturers: validate that helmets, firehoods, clothing, gloves, footwear, eye/face and hearing protection work together without degrading safety or mobility.
- Procurement/specifiers: use compatibility data to select PPE ensembles suitable for wildland operations.
- Testing labs and conformity assessors: perform required practical fit and function tests and prepare formal reports.
- Fire services and trainers: understand limitations of equipment ensembles, conduct risk assessments, and train users in selection, care and maintenance.
