A quiet night at Homestead Commons turned into a hazmat scene yesterday after an Ann Arbor resident reportedly mixed household cleaners in a bathroom, creating chlorine gas that left them unconscious and sent first responders scrambling.
Fire crews evacuated and ventilated the apartment, then called in specialized teams to make sure the rest of the building was safe. The person was taken to the University of Michigan hospital and was in stable condition, according to officials.
According to ClickOnDetroit, the Ann Arbor Fire Department arrived around 10 p.m. yesterday and found a strong chemical odor and an unconscious individual in the bathroom. Crews pulled the person to safety, and paramedics took them to the hospital in stable condition. The Washtenaw County Hazardous Materials Response Team was then called in to ventilate the unit and remove any lingering hazards.
How the gas forms
Mixing acids with bleach can release chlorine gas, which reacts with moisture on the eyes, nose, throat, and lungs to form corrosive acids that damage tissue and interfere with breathing. Federal guidance from NIOSH and the ATSDR notes that even low concentrations can cause eye and respiratory irritation, while heavier exposures may trigger coughing, wheezing, and fluid buildup in the lungs. In situations like this, emergency responders typically move affected people into fresh air and provide supportive medical care as needed.
A local pattern of risky misuse
The ClickOnDetroit report notes this is the second serious cleaning-product exposure in Ann Arbor in recent weeks. In the earlier case, a spa-treatment chemical used on a residential floor created another hazardous situation. Fire officials are using the pair of incidents to remind residents that household products tend to be safe only when used exactly as directed, and that mixing cleaners can create dangerous gases in seconds. Simple precautions, like reading labels, never mixing products, and keeping windows open while you work, can prevent most of these calls.
What residents should do
If you smell a strong chemical odor or start feeling sick while using cleaners, leave the area right away and call 911. Seek medical care if symptoms do not quickly improve. For non-emergency questions about disposing of hazardous household products, the City of Ann Arbor and Washtenaw County provide home-toxics information and scheduled collection sites for residents. If you suspect poisoning, call Poison Control at 1-800-222-1222 for immediate guidance.
