Book 26, Question 115
What do safety marks like CSA on a product mean?
A mark such as CSA in Canada, or UL in the United States, shows that an independent lab tested a product against safety standards.
It is common on electrical items such as chargers, lamps, and toasters. The lab checks that the item doesn't overheat or shock people during normal use. It does not mean a product is for play. Always follow the instructions.
