Note any areas on the EXTERIOR that you think could be asbestos containing:

House SidingCement and Plaster
Note any additional areas that could contain asbestos.
WARNING: It is important to consider the possibility of asbestos containing material. Any area that you are unsure of or suspect may contain asbestos should be sampled and sent to a lab. Contact C-NRPP for information on labs to assist in this (info@c-nrpp.ca)

Identify potential health and safety issues/concerns
Drawing of Blue Print of Building:

Based upon your visual inspection of the subject, draw a blue print of the construction details of the building including:
- Structural building elements: Eg. Footings, foundation walls, structural supports and bearings
- Below slab pipes/electrical lines/various locates
- In wall hydro, water, gas locates
- Identify any unseen concerns
- ID large openings in slab/mark sealing points
- Include distances and pipe runs
- Location of electrical outlets and panel; note if there is space in the panel, if required
- Include furnace, HVAC, hot water tank (note energy source)
- Identify any backdraft concerns
- Mark potential pick up point (include at least 2 options)
- Mark discharge locations (include at least 2 options)

It may be useful to make note of the following information while onsite to remind you of material that will be required for the full installation of the Radon Mitigation System.
Estimate of length of pipe required.
Number of pipe fittings
List any additional items required for install: (sump cover, unusual pipe and/or fitting, unusual tools or equipment)
In order to satisfy the requirements of the C-NRPP Mitigation Course the system needs to be installed in accordance to National Standard of Canada: Radon Mitigation options for existing low-rise residential buildings: P29-149-012-2024-eng.pdf.

Health Canada's Reducing Radon Levels in Existing Homes: A Canadian Guide for Professional Contractors as well as the C-NRPP Mitigation Course material will provide you with additional guidance to help with understanding this process. Where the documents don’t agree, the CGSB National standard should be followed.

In preparation for installing the Radon Mitigation System and completing the requirements of the C-NRPP Mentorship Process you will need to complete the following steps:
- Complete a System Design and enter information on the System Design Worksheet
- Determine the proper fan to be installed, based on the completed System Design Worksheet
- Install the Radon Mitigation System, complete the Completed Mitigation Worksheet
- Perform the Depressurization Test (in accordance with CSA F300-13) and complete the Depressurization Test Worksheet
C-NRPP has developed a Radon Mitigation System Installation Checklist to assist you in the process of the Radon Mitigation Installation. This is not meant to be complete guidance for installation, but rather a tool to use in conjunction with the proper guidance documents and training.
