WHMIS : Why do we need to read the label and be aware of the contents?


All to often individuals believe that by mixing common products together it will make the cleaning easier or faster. When they turn to products such as bleach and acid or strong alkali type products the results can be disastrous.

What happens in this situation is a poisonous gas is produced when the users decided to use a mixture of two or more common household cleaning agents. When the widely isded household chlorine bleach (a sodium hypochlorite solution) is combined with a acid or acid-producing substance, such as a toilet bowl cleaner or vinegar, there is a sudden release of a quantity of chlorine gas. Likewise, when a chlorine bleach is mixed with ammonia, lye, or other alkaline substance, the action will liberate a highly irritating gas.

If the gas is inhaled. in either case, it can cause serious injury and possible death. Accidents of this type have occurred not only the kitchen and bathroom, but also in the cleaning and treating of the water in swimming pools.

WHMISDont make the mistake of thinking that because a certain household products are good and useful, the combination of two or more of them will do a better job than one alone. Very often mixing them is useless and unneccessary since combined they will not make the job of cleaning easier nor give better results; and sometimes combining them may be disastrous. Follow the safe rule – use chemical cleaners as the manufacturer directs on the labels, and keep in mind some scouring(abrasive) powders not contain chlorine bleach.
