Hazardous Substance Sign FAQs

  • Yes. SMI’s signs are made from UV-resistant, chemical-resistant, and weatherproof substrates designed to perform in corrosive, wet, or outdoor environments. They maintain legibility even when exposed to cleaning chemicals or industrial dust.

  • Yes. Visible, up-to-date hazard signage demonstrates that your site meets health and safety and COSHH requirements. It also supports internal audits by ensuring staff and inspectors can easily identify risk zones and chemical storage areas.

  • SMI provides a wide range of hazardous substance signage, including COSHH chemical symbols, gas cylinder warnings, corrosive material labels, and explosion risk signs. Each design follows recognised hazard pictogram standards to ensure immediate recognition and clear communication of risk.

  • Install signage at all key hazard points. This includes chemical storage areas, handling zones, pipework routes, and containment rooms. Positioning at eye level and near access points ensures risks are visible to everyone entering or operating in the area.

  • All signs are compliant with the Control of Substances Hazardous to Health (COSHH) Regulations, REACH, and CLP (Classification, Labelling and Packaging) standards. These frameworks ensure that substances are clearly labelled with the appropriate hazard symbols, colours, and wording to meet UK and international safety requirements.

  • SMI can produce custom hazardous substance signs to meet unique site requirements - including additional text, company branding, or multilingual versions to support international teams. To discuss bespoke designs, contact the team.

  • Review all hazard signs regularly. At least annually, or sooner if classifications change, materials are re-labelled, or signs become faded or damaged. Maintaining clear, accurate signage is vital for ongoing COSHH compliance and audit readiness.
