What is an OFTEC TI/133D?
The OFTEC TI/133D is the Oil Storage Tank Risk Assessment. It assesses the fire and pollution risk when siting an oil storage tank and helps determine the required separation distances and any bunding.

OFTEC TI/133D Oil Storage Tank Risk Assessment
The OFTEC TI/133D is the Oil Storage Tank Risk Assessment used to assess the pollution and fire risk when siting an oil storage tank. It helps determine the separation distances required and whether the tank needs to be bunded to control the risks.
TradePlanr lets you work through the TI/133D on your phone or tablet at the site, record the risk factors and produce a clear PDF that supports your tank installation. It keeps the assessment tidy and easy to hand over.
Each assessment is saved against the customer and property, so the reasoning behind the tank siting, separation distances and bunding is documented and easy to retrieve later.

What it covers
- Property address, customer details and the proposed tank location
- Oil storage tank type and capacity being assessed
- Proximity to buildings, boundaries, openings and other structures
- Fire risk factors and the separation distances required for the siting
- Pollution risk factors such as watercourses, drains and ground conditions
- Whether integrally or externally bunded tank arrangements are required
- OFTEC registration number, engineer declaration and assessment outcome
When it's required
A TI/133D is completed when siting an oil storage tank, whether for a new installation or a replacement. It assesses the fire and pollution risks at the proposed location to establish the required separation distances and whether bunding is needed.
The assessment supports the tank installation and should be kept with the property and installation records. It provides documented justification for the siting decisions, which is useful for the customer, future engineers and any later completion reporting.
How to issue it in TradePlanr
- 1
Enter the site and tank details
Open a TI/133D, add the customer and property, then record the proposed tank location, tank type and capacity being assessed.
- 2
Assess the fire risk factors
Record the proximity to buildings, boundaries and openings to work out the fire separation distances required for the tank siting.
- 3
Assess the pollution risk and bunding
Log pollution risk factors such as watercourses, drains and ground conditions, and determine whether bunding is required for the installation.
- 4
Sign and store the PDF
Confirm the assessment outcome, capture the signature, then generate a branded PDF that is emailed to the customer and filed against the job.
Frequently asked questions
When do I need a TI/133D?
You complete a TI/133D when siting an oil storage tank for a new or replacement installation, to assess the risks at the proposed location and establish the separation distances and bunding needed.
Can I complete OFTEC forms on my phone?
Yes. TradePlanr lets you work through the TI/133D on your phone or tablet at the site, capture a signature and email the customer a PDF without any paperwork afterwards.
What does the TI/133D help determine?
The TI/133D helps determine the separation distances required for a tank based on fire and pollution risk, and whether the installation needs an integrally or externally bunded tank.
