Decontamination Log

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 decontamination log is

A decontamination log records when equipment, surfaces, vehicles or PPE were cleaned of hazardous substances — chemical, biological or other — and by what method, so contamination is controlled and people are not exposed second-hand.

This page is an educational overview with a simplified example. It is not an official template, not jurisdiction-specific and not legal advice — decontamination methods and standards vary by substance, setting and country.

Purpose

• Record decontamination of equipment, areas or PPE.
• Show contamination is being controlled at handover or reuse.
• Capture the method and any verification.
• Support exposure control and hygiene.

Who maintains it

• The person carrying out decontamination records it.
• A safety or hygiene lead reviews and oversees the process.
• The method follows the assessment for the substance.
• The employer decides the process and who is responsible.

When it is used

• After equipment or an area contacts a hazardous substance.
• Before equipment is reused, returned or maintained.
• After a spill clean-up.
• When PPE or tools are cleaned for reuse.

Typical fields

• Item, equipment or area decontaminated.
• The contaminant involved.
• Method and products used.
• Verification or check that it is clean.
• Who carried it out, date and sign-off.
• Example columns only — adapt to your substances and the applicable law.

Common mistakes

• Using a method that does not suit the contaminant.
• Returning or reusing items before they are verified clean.
• Spreading contamination through poor technique.
• Not protecting the person doing the decontamination.

Document workflow

A decontamination log works with the exposure and incident chain: a substance assessment or spill sets the need, decontamination is recorded here, and the item is released for reuse or maintenance afterwards. It links to the spill, biological agent and exposure records.

See the related documents below for what is commonly required before and used with a decontamination entry.

Retention (high level)

Decontamination records are generally kept for a period set by the applicable law and the employer’s obligations, long enough to show items were made safe. This page does not state a required period — confirm with the applicable law and the official authority.

Completing and sharing as a PDF

The log is often held on forms or in a system and exported to PDF. Exporting to PDF supports the record; it does not make it official or prove compliance.

Employer checklist

• Match the decontamination method to the contaminant.
• Verify items are clean before reuse or handover.
• Protect the person doing the decontamination.
• Keep the log linked to the substance assessment.

Worker notes

• Decontaminate equipment and PPE as the procedure requires.
• Do not reuse or pass on items that are not verified clean.
• Protect yourself while decontaminating contaminated items.

Country considerations

Decontamination standards and methods vary by substance, setting and 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 contamination 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.
