Final answer:
The Ontario Fire Code requires carbon monoxide alarms in condos and apartment buildings near sleeping areas and where there are fuel-burning appliances or attached garages. These alarms are crucial due to carbon monoxide being colorless and odorless, and can prevent CO poisoning.
Step-by-step explanation:
The Ontario Fire Code mandates the installation of carbon monoxide alarms in condominiums and apartment buildings to ensure the safety of the inhabitants. These alarms are particularly vital in buildings where there are fuel-burning appliances or attached garages, as they can leak carbon monoxide (CO), a colorless and odorless gas that is extremely dangerous at high levels. The requirements for carbon monoxide alarms are as follows:
- Alarms must be installed near all sleeping areas in residential units that contain a fuel-burning appliance or have an attached garage.
- Additionally, alarms must be installed in service rooms and adjacent to sleeping areas in buildings with a service room that contains a fuel-burning appliance.
- Regular maintenance, such as ensuring that vents and chimneys are working properly, is crucial to preventing CO buildup.
The rationale for prioritizing the detection of carbon monoxide over other gases like ammonia or natural gas is that CO is both lethal and undetectable by human senses, making it one of the most stealthy and dangerous household threats. Many deaths from carbon monoxide poisoning have been prevented thanks to the timely alerts provided by these detectors. While there can be an associated cost, the implementation of these safety measures aligns with broader building codes designed to protect inhabitants' health and safety.
