Proposed Ontario Building Code (OBC) Changes - period of review open until Dec 20

Dec 7, 2016

The Canadian Association of Radon Scientists and Technologists (CARST) is making efforts to encourage all citizens to join in the effort to advocate for changes to the building code.  Acceptance of proposed changes to Ontario Building Code (OBC) are governed by consensus.  Residents of Ontario need your help to protect their lives and health by ensuring radon testing is conducted in all new construction. 

The Ontario Building Code is currently open for review on proposed changes and are accepting comments until December 20.

3.1.1.2    Radon   

5.4.1.1    Resistance to Air Leakage

6.2.1.1    Good Engineering Practice

9.1.1.7    Radon

9.13.4.1   Soil Gas Control

9.13.4.2   Required Soil Gas Control

9.25.3.1   Required Barrier to Air Leakage

According to Public Health Ontario, almost 850 lung cancer deaths that occur each year in Ontario are attributable to radon (2)(Ontario Public Health, 2016), yet mandatory radon testing for all newly constructed buildings with residential occupancy is not in the current OBC.  

Eleven (11) people, on average, in Ontario die annually from carbon monoxide poisoning (1)(Ontario Association of Fire Chiefs 2016).  Radon kills 77 times more people in Ontario every year than carbon monoxide.  Both inhalable gases (i.e. carbon monoxide, radon) are colourless and odourless and both gases pose a risk to almost all Canadians. Precedence has dictated that building code requirements are in place to protect 11 Ontario residents annually from death due to toxic carbon monoxide, so surely such protection is prudent to protect 850 Ontario residents annually, and future occupants, from death due to radon induced lung cancer.

 

We would like to see that the changes to the OBC include mandatory radon testing and that the testing be completed by certified C-NRPP Measurement Professionals.
