ISO 26261-4:2017

Overview

ISO 26261-4:2017 is an international standard that specifies the minimum labelling requirements and mandatory instructions for use for Category 4 fireworks. This standard ensures that fireworks are labelled clearly and comprehensively to promote safe handling, use, and disposal. It applies exclusively to Category 4 fireworks and excludes theatrical pyrotechnic articles used in stage productions, film, or television.

Developed by ISO Technical Committee ISO/TC 264, the standard emphasizes labelling transparency, traceability, and user safety. It is intended to harmonize the information presented on fireworks across member states, facilitating compliance with national regulations and enhancing consumer safety.

Key Topics

• Minimum Labelling Information:
  Every Category 4 firework must be marked with key data including:

  • Name and type of firework (e.g., “Shell” or “Bengal flame”)
  • Category and registration number with batch traceability
  • Net Explosive Content (NEC)
  • Safety and disposal instructions
  • Year of production
  • Manufacturer or importer details including name and address
  • Clear, legible printing on contrasting backgrounds

• Safety Information:
  Labels must include warnings such as "For use only by persons with specialist knowledge" prominently. Safety parameters required on labels include:

  • Burst height or effect height (A)
  • Sound pressure level (B)
  • Distance debris can be projected (C)
  • Presence of incendiary or burning matter (D)
  • Range for aquatic fireworks (E)
  • Duration for aerial wheels (R)
  • Maximum firing angle if applicable (W)

• Labelling of Small Items:
  For fireworks too small to carry full labels, at minimum, manufacturer details must be present on the firework, with the rest of the information supplied on a protective pack label marked “Must be supplied as packaged.”

• Specific Item Labelling:

  • Combinations with multiple fuses require clear identification of each fuse.
  • Firing orientation and maximum angle must be labelled if not obvious.
  • Shells requiring specific mortars must indicate this on the label and in instructions.

• Operating Instructions:
  Detailed instructions covering safe handling, storage, usage, and disposal must accompany the product. They must include any special equipment requirements and firing directions as necessary.

Applications

ISO 26261-4:2017 applies directly to manufacturers, importers, distributors, and retailers of Category 4 fireworks. These are large-scale consumer or professional fireworks that require stringent safety labelling due to their size and explosive content.

Practical applications include:

• Consumer safety: Ensuring users have essential data for safe use avoids accidents.
• Regulatory compliance: Harmonizing labels supports meeting national and international legal requirements.
• Traceability: Registration numbers and batch info assist in quality control and recall management.
• Market transparency: Clear labelling builds consumer trust by communicating safe handling and expected effects.

This standard is critical for fireworks producers ensuring products are correctly labelled for international markets and for government agencies enforcing safety regulations.
