Chemicals which are generally for domestic use and considered safe in the home may present greater risks in the workplace depending on the manner and quantities in which they are used. This is particularly relevant, for example, where domestic cleaning chemicals are purchased from a supermarket and used in a workplace environment. You should always follow label directions. However, if you are using a domestic chemical in a manner different to normal household use, you should also obtain the SDS in order to determine the level of risks to workers and the appropriate controls. The SDS should contain more detailed information on hazards and risks, for example on incompatibilities with other chemicals and risks from use in enclosed areas.
Hence, if the chemical is a domestic chemical used for a domestic purpose i.e. dish washer chemical, then an SDS is not required and it does not need to be included in the register. For the methylated spirits however, it’s use is commercial and therefore an SDS would be required and it needs to be included in the Register. Refer WHS Regulations s344 (4).
