Chemical Register

Educational guidance on registers and logs — what each records, who maintains it, what it typically contains and how long it is generally kept. Informational only — template examples, not official documents or legal advice; a register documents activity, it does not by itself prove compliance, and employers remain responsible.

What a chemical register is

A chemical register (or hazardous substances inventory) is a list of the substances present at a workplace — cleaning products, solvents, gases, adhesives and the like — linked to their safety data sheets and the assessments that control their use.

This page is an educational overview with a simplified example. It is not an official template, not jurisdiction-specific and not legal advice — the employer decides what their inventory records and how substances are controlled.

Purpose

• Know which hazardous substances are present and where.
• Link each substance to its safety data sheet and assessment.
• Support safe storage, handling, use and disposal.
• Inform emergency planning and first aid.

Who maintains it

• A safety lead, store controller or manager keeps it current.
• Those who buy or use substances feed in changes.
• Safety data sheets come from suppliers.
• The employer decides scope and ownership.

When it is used

• When a new substance is brought on site.
• When a substance is removed or replaced.
• When assessing the risk of a substance’s use.
• During emergency planning and inspections.

Typical fields

• Substance name and supplier.
• Hazard classification and quantity or location.
• Link to the safety data sheet and the assessment.
• Storage and handling notes.
• Date added or reviewed.
• Example columns only — adapt to your substances and the applicable law.

Common mistakes

• Listing substances without the current safety data sheet.
• Letting the inventory drift out of date as products change.
• Recording substances but not assessing their use.
• Storing incompatible substances together.

Document workflow

A chemical register feeds substance risk assessment: a new substance is added to the inventory with its safety data sheet, its use is assessed, and controls — storage, handling, PPE — follow. Spills or exposures may trigger an incident record and a review.

See the related documents below for what is commonly used with and completed after a chemical register entry.

Retention (high level)

Inventory and assessment records are generally kept for a period the employer sets in line with its obligations, and some health-exposure records may need to be retained for a long time. This page does not state a required period — confirm with the applicable law and the official authority.

Completing and sharing as a PDF

A chemical register is often held in a system with linked safety data sheets and exported to PDF for records and emergency reference. Exporting to PDF supports the record; it does not make it official or prove compliance.

Employer checklist

• Keep the inventory current as substances change.
• Hold the safety data sheet and an assessment for each substance.
• Control storage, handling, use and disposal.
• Make the register available for emergency planning.

Worker notes

• Use substances only as the assessment and label allow.
• Know where the safety data sheets and the register are kept.
• Report spills, exposures or unlabelled substances.

Country considerations

How hazardous substances must be classified, recorded and controlled varies by country, and the official authority differs. This page is general and high-level — not a statement of any country’s law and not legal advice.

Confirm current requirements with the official authority for your country and a qualified professional.

Who is responsible

The employer is responsible for controlling hazardous substances and for compliance. This page is an educational overview with a template example; it does not make a workplace compliant and does not transfer responsibility.
