Unsafe Substances

Some substances around us are unsafe, for examples, bleach liquid, insecticide, liquid paper, detergent and cough syrup. These unsafe substances  are usually packed in containers/packages with labels and symbols.

Labels
  • provide much of the information you need to know on how to use the substances safely
  • may use signal words to show how toxic or hazardous (involving risk and danger) the substances can be either: 
'Danger' means it is the most hazardous kind of material
'Warning' is less hazardous than Danger, but more hazardous than Caution
'Caution' is the least hazardous rating 
Mind Map on Unsafe Substances' Symbols (Year 3)
Symbols
  • show the harms that may be caused by the substances 
  • are one of the key elements of a safety label
  • have the ability to communicate across language barriers

There is always a need for kids to ask an adult before touching, smelling or tasting any unsafe substances. The unsafe substances should  be kept away in a place that is not reachable by kids. For adults, always look and read the labels or directions of usage carefully before handling any substances. It is better to be safe than sorry.
