If old furniture has lead-based paint, watch to prevent your children from chewing it. Never leave a young child alone to go to the phone or answer the door, especially if there is a possible poison in the room. There are four common poison dangers for adults. Vapors and fumes from space heaters, cars and charcoal grills can be deadly. Always operate them with plenty of fresh air circulating.
Carbon monoxide has no smell, color or taste, but it can kill someone in a few minutes.
Drugs, even aspirin, can make you ill. Take only the amount directed by your doctor or the drug manufacturer. Never give left-over prescription drugs to anyone else. Read medicine labels in good light to be sure you're taking the right amount and the right medicine. Cleaners can be dangerous, especially if they are not in their original containers and are mistaken for another product.
