These days it seems like every product comes with a warning, so you may not pay much attention to the words on the label. However, reading labels is the easiest way to identify hazardous products. When shopping for household products, choose the least hazardous product for the job.
Signal words
Descriptions on labels will tell you how hazardous a product is.
- Caution – mild to moderate hazard
