Signal Words

When you read product labels, look for signal words. Signal words are found on labels of new products and let you know how toxic a product is. Older products in your home may not list signal words. Drugs and personal care products are not required to list them, although many are hazardous.

Poison – highly toxic

Danger – extremely flammable, corrosive, or highly toxic

Warning – moderate hazard

Caution – mid/moderate hazard

No signal word – not hazardous
