Car Park Ventilation Safety & Australian Regulations

Enhancing Car Park Ventilation Safety: Understanding Carbon Monoxide (CO) Regulations

Introduction to the Dangers of Poor Car Park Ventilation:

While car parks may seem unassuming, they can harbor unexpected dangers, including the silent threat of Carbon Monoxide (CO). This colourless, odorless, and tasteless gas is produced by combustion engines, stoves, grills, and various other sources, posing a significant health risk. This is why there are strict requirements for car park ventilation systems and maintenance.

Understanding Carbon Monoxide:

Often referred to as the “silent killer,” Carbon Monoxide is deceptively stealthy. Its symptoms, which can mimic the flu, include headaches, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. In severe cases, exposure to high levels of CO can lead to unconsciousness or even death. Worryingly, individuals who are asleep or under the influence of alcohol can succumb to CO poisoning without exhibiting any symptoms.

Australian Standards For Car Park Ventilation:

To mitigate the dangers of CO, Australia has established precise regulations, particularly within AS1668.2-2012, outlining safe exposure limits and control measures for environments like car parks. These standards unequivocally stipulate that car parks – lacking sufficient natural ventilation – must incorporate mechanical ventilation systems. Moreover, these mechanical ventilation systems must operate ceaselessly at their full ventilation rate.

Exceptions are made for car parks with fewer than 40 car spaces, where the installation of an occupation monitoring system is a permissible alternative to atmospheric contaminant monitoring. However, all other car parks must have a continually operating mechanical ventilation system.

The Imperative of Continuously Monitoring Car Park Ventilation & CO Levels:

Regrettably, a prevalent practice in many car parks involves the use of time clocks to regulate car park ventilation systems exclusively during peak periods. This approach is not only hazardous but also legally questionable. In such instances, car parks remain unmonitored during non-peak hours, leaving occupants exposed to the potential risk of carbon monoxide poisoning.
