Hazardous Substances

• Use Hazardous Substance Register to create or update each site's register.
• Level 1 and Level 2 users can view saved registers, PDFs, and uploaded hazardous-substance documents only.
• Level 3+ users can open and update the Hazardous Substance Register and upload SDS/supporting documents against the correct site.
• Use the register search to find registers or uploaded documents by site, substance, UN number, storage details, reviewer, SDS expiry, review details, or file name.
• Company Sites are shown first and open by default. Other / Client Sites are in a separate dropdown that starts closed.
• Empty Other / Client Sites are hidden by default. Tick Show empty sites inside that section header to reveal them. Company Sites always remain listed.
• Individual site rows stay open after opening a register, viewing PDFs, or deleting records.
• Level 3+ users can open the register to Save, Draft PDF, or Approve inside the form.
• The most recent approved PDF always shows under the live register row.
• Tick Show Archived to reveal older approved PDFs for cleanup. Older approved PDFs can be deleted individually without deleting the live register.
• Word, Excel, and PowerPoint files show View and Download. Other files show Open.
• Level 4 users can delete. Delete is a hard delete: Firestore records are removed and any stored files/PDFs are purged first.
