What HACacare does

Hazardous area classification

For engineers producing a classification.

  • IEC 60079-10-1:2020 — gas & vapour zone classification: release rate, ventilation and dilution, zone type, zone extent
  • IEC 60079-10-1:2020 Annex F — qualitative classification
  • IGEM/SR/25 — natural gas installations
  • CEN/TR 15281 — inerting
  • IEC 62485-2 — stationary battery rooms
  • IEC 62485-3 — traction battery charging areas
  • EN 16985 — spray booths
  • EN 1539 — dryers and ovens
  • IEC/TS 60079-32-1 — electrostatic hazards

Projects, sharing with colleagues, Excel and PowerPoint reports.

Operation and maintenance

For site engineers checking an installation that already exists.

  • CEN/TR 15281 — inerting: is the existing purge sequence still sufficient?
  • IEC 62485-2 — battery rooms: required ventilation against the installed extraction capacity or opening area, and the safety distance
  • IEC 62485-3 — traction battery charging: the same, per charging spot, with the free-volume alternative
  • EN 16985 — spray booths: concentration against the standard's ceilings, and the declared zone verified against the computed one
  • EN 1539 — dryers: is the installed ventilation enough for the actual load?
  • IEC/TS 60079-32-1 — electrostatic hazards

Standards-cited operating checklists as Word documents, and a way to preview the effect of a planned change before a full management-of-change review.
