Bleach & Mixing Cleaners
Spot it
A bucket or toilet bowl you topped up with 'a little of this and a little of that' for a big cleaning job; bleach poured in after another cleaner without rinsing; a bleach jug on the floor or a low shelf within a toddler's reach.
Fix it
Poison Control: bleach plus ammonia (found in some glass cleaners) makes chloramine gas (Poison Control says this is less likely to cause serious toxicity than chlorine gas), and bleach plus an acid (vinegar, some toilet bowl cleaners) makes chlorine gas. Symptoms are burning eyes, nose and throat and coughing; heavier exposure can cause shortness of breath, wheezing and chest pain. If it happens, leave the area right away, get fresh air, and call Poison Help at 1-800-222-1222; get medical care for trouble breathing. A CDC MMWR report documented chlorine gas poisoning when bleach was mixed with an acid cleaner. AAP's rule is simply never to mix cleaning products and to follow the label. Keep bleach in its original bottle and, like other cleaners, up and away from children (AAP: spray bottles are a common source of unintentional poisoning). Using one product at a time and rinsing the surface between them is our practical reading of the no-mixing rule, not from the cited pages.

No shopping list for this hazard — the fix is a habit, not a purchase.
