Chemicals are an integral part of effective cleaning practice. They are essential but at the same time they can be harmful.
There are some important rules to follow which can minimize that risk.
SDS and CHARTING
Know where your Safety Data Sheets are and familiarize yourself with the wall charts for the products used in your work. They have important information about DG codes, PPE requirements , health effects.
IDENTIFICATION
Ensure that you correctly identify the product in a chemical container
Read the label, is it the product in the container?
Note the safety instructions on the label
Take special note of DG label (Dangerous Goods)
CLASS 8 is corrosive (to you and equipment)
CLASS 5.1is Flammable (can catch fire)
Are the products in the correct containers with approved (and correct) labels
Do not use:
Product in unlabelled bottles
Labelled bottles with incorrect product in the bottle
Non approved bottles e.g. drink bottles
Containers with hand written labels
If you discover any of these faulty containers dispose of them or report them to your supervisor.

Keep liquids away from overhead wiring and electrical motors
Do not carry chemicals in open top containers. Dropping may cause splash back
Do not use a spray applicator to apply chemical above your shoulders – mist floats – without a respirator you are in danger.
Do not mix chemicals – WHAT CAN HAPPEN
Chemicals will not mix
Colour change endangering identification
Chemicals will be neutralized – ineffective product results
or
Violent reactions including
Boilovers
Explosion
Toxic gas emissions
The important message in this section is “trust the science”. Fully qualified experts have created chemical formulations to perform specific tasks, any amateur effort to improve them creates only an opportunity for a dangerous reaction.
PPE - PERSONAL PROTECTIVE EQUIPMENT
Basic PPE includes:
Eye protection
Gloves
Safety boots – generally rubber Gumboot type
