Scope

ISO 25901-2:2022 defines terms and definitions related to health, hygiene and safety aspects of welding and allied processes. It is intended to be referenced by other documents and standards that address occupational safety, industrial hygiene and risk controls for welding activities. The publication organizes terms systematically and provides multilingual indexes (English, French and German) to support consistent usage across documents and jurisdictions.

Key topics and requirements

• Standardized terminology for hazards associated with welding (fumes, gases, radiation, hot work, fire/explosion risks).
• Definitions for control measures and protective equipment (local exhaust ventilation, fume extraction, respiratory protective equipment, PPE).
• Terms covering occupational hygiene, exposure assessment and health surveillance concepts relevant to welding environments.
• Vocabulary for emergency measures, training and competence, and safe work practices for welding and allied processes.
• Multilingual indexing and cross-references to ensure consistent interpretation in English, French and German.

These topics reflect the document’s role as a vocabulary/reference for health and safety in welding rather than prescriptive technical requirements.

Typical use and users

Used by standards writers, regulatory bodies, occupational health and safety professionals, welding engineers, safety trainers, health & safety auditors, and employers to ensure consistent terminology in safety policies, risk assessments, training materials, procurement specifications and technical regulations related to welding operations.
