Overview

EN ISO 7010:2020/A5:2023 is the CEN-adopted Amendment 5 to ISO 7010 (Graphical symbols - Safety colours and safety signs - Registered safety signs). Published March–June 2023, this amendment adds three registered safety signs to the ISO 7010 collection and updates the European implementation. The amendment was prepared by ISO/TC 145 and endorsed by CEN for mandatory national adoption by September 2023. All new signs are available on the ISO Online Browsing Platform.

Key topics and requirements

• New registered safety signs added

  • M056 – Ventilate before and during entering
    • Function: signify that a space (room, tank, container) must be ventilated before and during entry.
    • Hazard: toxic gas concentration or oxygen depletion.
    • Note: supplementary text or training is recommended because ISO 9186-1 comprehension test data are not available.
  • M057 – Ensure continuous ventilation
    • Function: signify that continuous ventilation must be ensured to prevent accumulation of hazardous emissions.
    • Note: supplementary text recommended where manuals/training do not apply.
  • M058 – Entry only with supervisor outside
    • Function: signify that entry is permitted only when a supervisor is stationed outside with a phone to call for help.
    • Hazard: occupant may be unable to exit or call for help after an accident.
    • Note: supplementary text recommended unless supplemented by instructions or training.

• Colour and image guidance

  • The amendment reiterates that electronic colour reproductions are not true colour matches; for colorimetric properties and matching guidance users should refer to ISO 3864-4.

• Conformity and publication

  • This amendment is integrated into the European standard without modification (EN ISO 7010:2020/A5:2023) and national members must implement it.

Applications and who uses it

• Workplace safety and HSE professionals: incorporate signs into confined-space entry procedures, ventilation policies, permit-to-work systems.
• Safety sign designers and manufacturers: produce compliant pictograms and supplementary text signs following registered formats.
• Facility managers & plant operators: install appropriate signage at rooms, tanks, containers and update training and emergency procedures.
• Safety auditors and trainers: ensure signage comprehension and that supplementary instructions or training accompany these signs where ISO 9186-1 data are missing.

Related standards

• ISO 7010 (base standard for registered safety signs)
• ISO 3864-4 (colour matching and colourimetric guidance)
• ISO 9186-1 (symbol comprehension testing - test data for these signs are not available)

This amendment strengthens the ISO 7010 library for graphical symbols, safety colours, and registered safety signs, particularly for ventilation and confined-space safety, aiding consistent international implementation.
