Approved Filler Certification Evidence Gathering and Assessment

Proof of identity 
Please upload a clear, recent copy of either your passport photo page or your New Zealand driver licence.
The name on this document must exactly match the name you entered on the application form.
Matching, legible ID allows us to verify your identity quickly and prevents delays caused by spelling discrepancies.

Completed application form 
Every field on the form must be completed accurately and written legibly.
Precise answers enable a fair, consistent assessment, streamline processing time, and keep communication with you efficient.

Current Safety Data Sheets (SDS) 
Attach the most recent, compliant Safety Data Sheet for each substance you will handle.
Up‑to‑date SDS information ensures safe handling practices and helps us confirm that hazards are correctly identified.

Signed Standard Operating Procedure (SOP) 
Provide a copy of your cylinder‑filling SOP signed by both you and your manager.
The signatures confirm that all staff have been trained and that the documented procedure is followed in daily operations.

Photographic evidence of safe filling practice 
Include images that demonstrate your competence and the integrity of your equipment:

  • Proper use of PPE (gloves, goggles, face shield, etc.).
  • Close‑ups of cylinder markings – test date and LAB number (if applicable).
  • Proof the cylinder is fit for service – no rust, dents, valve damage, oil, or grease.
  • Visible empty weight / tare weight (EW/TW) or filling pressure.
  • Calibrated filling rig – photo of current calibration sticker.
  • All supporting equipment present (e.g. temperature gauge for oxygen filling).
  • Leak‑check in action (soapy water or equivalent).
    If a fault is found, include a photo showing the cylinder or valve tagged out for repair.

A copy of the Rifft Solutions Approved Filler certificate 
Attach the certificate issued after you completed our online Approved Filler training course.

This confirms you have met the competency standard required for safe cylinder filling.

Frequently Asked Questions

Why must my ID match the name on the application form exactly?

Verifying that your legal ID and application details are identical protects you from identity errors
and lets us confirm your eligibility without requesting further documents, which speeds up approval.

Which Safety Data Sheets do I need to include?

Provide the most recent SDS for every gas or liquid you intend to fill.
Each SDS must comply with current New Zealand regulations and include hazard classifications
so we can confirm you have the right controls in place.

What counts as acceptable photographic evidence?

Photos must be clear, well‑lit, and show each checklist item — PPE, cylinder markings,
leak‑checks, calibration stickers, and so on.
Mobile‑phone photos are fine as long as details such as test dates and gauge readings are readable.

Do I need to photograph every cylinder I fill?

No — sample photographs are acceptable provided they clearly show your standard
filling process and the condition of typical cylinders and equipment.

Where can I obtain the Rifft Solutions Approved Filler certificate?

Complete our online Approved Filler training course.
On passing the final assessment, you can download the certificate immediately from your user dashboard.

Is a digital signature on the SOP acceptable?

Yes. A secure digital signature from both you and your manager is acceptable, provided it is date‑stamped
and uniquely attributable to each signatory.
