DisclaimerThese tools have been developed by Comsol Limited as practical aids for hazardous substances compliance. They are calculators and reference resources only — they do not constitute legal, regulatory or compliance advice. Always verify every output against the Health and Safety at Work (Hazardous Substances) Regulations 2017, the relevant Schedules and EPA Notices, the underlying AS/NZS standards, and your professional judgement. If in doubt, consult your compliance certifier.Where any tool uses AI, it runs on a Pro subscription tier. AI responses can still contain errors or omissions, so the same rule applies: cross-check against the regulations and your certifier before relying on anything for a compliance, legal or regulatory decision.Comsol Limited accepts no liability for decisions made on the basis of these tools or any AI-generated content within them.
