What does the phrase 'limit the probability' acknowledge?

The phrase 'limit the probability' recognizes the inherent limitations within building regulations when it comes to preventing undesirable situations. It acknowledges that while the Ontario Building Code sets standards and guidelines aimed at reducing risks related to safety, health, and usability in buildings, it cannot guarantee that such unwanted events will never occur. The very nature of construction and the multitude of variables involved—such as environmental factors, human behavior, and unforeseen circumstances—means that achieving absolute safety or elimination of all risks is not feasible.

By focusing on 'limiting the probability,' the Building Code emphasizes a proactive approach, aiming to minimize risks through design and compliance, rather than providing an unrealistic expectation that all potential hazards are completely preventable. This understanding of risk management is crucial in the context of building safety standards.
