What are the SafeWork NSW rules for cleaning chemicals?

Australian work health and safety law places the primary duty on the person conducting a business or undertaking. In a cleaning context that means both the cleaning contractor and the business occupying the building hold duties, and those duties overlap rather than transfer.

The contractor is responsible for the chemicals it brings on site, for training its own workers and for supplying appropriate protective equipment. The occupier is responsible for the workplace itself, for consulting and coordinating with the contractor, and for making sure the arrangements between the two organisations actually work in practice.

That shared duty is why a facilities manager cannot treat chemical safety as purely the cleaner problem. If a chemical is stored in a shared plant room, or if a cleaner works alone in an empty building after hours, the occupier has a legitimate interest and a legal exposure.

A safety data sheet is the manufacturer document describing what a chemical is, what harm it can cause, how to handle and store it, what protective equipment to use, and what to do in an emergency or a spill. It is the foundation of every other control.

The requirements are straightforward. The business must obtain the manufacturer or importer safety data sheet before the chemical is first used at the workplace, keep it current, and make it readily accessible to any worker who uses or could be exposed to the chemical, and to emergency services.

Readily accessible means genuinely available at the point of use, not filed at head office. A folder in the cleaner store room works. A shared electronic system works, provided the person on site at ten at night can actually open it on a phone. Safety data sheets are expected to be kept current, and manufacturers reissue them periodically, so a review cycle is needed rather than a one-off collection exercise.

Australia uses the Globally Harmonised System of Classification and Labelling of Chemicals. A supplied container must carry a compliant label with the product identifier, hazard pictograms, signal word, hazard and precautionary statements and supplier details. Australia has moved through successive GHS revisions, so confirm the current version with Safe Work Australia or SafeWork NSW rather than relying on an older reference.

The failure point in cleaning is almost never the supplied drum. It is the spray bottle. Cleaning chemicals are routinely bought as concentrate and decanted into trigger bottles for use, and once a chemical leaves its original container the label obligation follows it.

A decanted container used beyond immediate personal use during that shift must be labelled with at least the product name and the relevant hazard information. An unlabelled blue spray bottle in a cleaner trolley is one of the most common findings in a workplace inspection, and it is entirely avoidable with a printed label set matched to the products in use.

Where hazardous chemicals are used, handled or stored at a workplace, a register must be maintained. In its simplest form the register is a list of the hazardous chemicals at the workplace with the current safety data sheet for each one, and it must be readily accessible to workers.

For most cleaning operations that is the whole obligation and it is a short document. A cleaning contractor servicing a standard office building might have a register of ten to twenty products.

Additional obligations attach once quantities of certain classes of chemical exceed prescribed thresholds, including manifest and notification requirements and, in some cases, placarding. Bulk storage of chemicals such as concentrated acids, chlorine products or flammable solvents can move a site into that territory. If your site holds chemicals in bulk rather than in working quantities, check the thresholds with SafeWork NSW rather than assuming the simple register is sufficient.

Storage is where cleaning chemical incidents actually happen, and the single most common cause is incompatible products stored together. The classic example is mixing a chlorine-based product with an acidic descaler, which releases chlorine gas. In a small unventilated cleaner cupboard that is a serious incident.

Segregate by chemical class according to the safety data sheets, and where two products should not be stored together, physically separate them rather than relying on a shelf label. Keep acids and alkalis apart, keep oxidisers away from organics and flammables, and keep everything out of direct sun and away from heat sources.

Ventilation matters as much as segregation. A cleaner store that is a sealed cupboard under a stair concentrates vapour, and the person opening it in the morning gets the full dose. Containment matters too: a bunded tray or a spill kit under bulk containers turns a serious spill into a manageable one.

The duty is not simply to hold documents. It is to identify the hazards, assess the risks and eliminate or minimise them so far as is reasonably practicable, following the hierarchy of controls.

For cleaning chemicals, elimination and substitution are underused and highly effective. Choosing a lower-hazard product, or buying ready-to-use dilutions instead of concentrates so nobody has to decant, removes the risk rather than managing it. Closed dosing and dilution systems do the same for the highest-risk step.

Personal protective equipment is the last line, not the first, but it still has to be right, available, maintained and actually worn. Gloves must be a material suited to the chemical, because a nitrile glove and a latex glove are not interchangeable across all products.

Training must be specific to the products in use, not generic. A worker should be able to say what a product is for, what its hazards are, what dilution to use, what protective equipment is required and what to do if it is splashed or spilled. Keep a record of who was trained, on what, and when, and repeat it when products change.

Every site needs an arrangement for what happens when something goes wrong, proportionate to what is stored there. For a typical office cleaning operation that is a short procedure and a spill kit. For a site holding bulk chemicals it is considerably more.

The procedure should cover who is notified, how the area is isolated, what protective equipment is used for the clean-up, how the waste is disposed of, and when emergency services are called rather than managed internally. It should also cover first aid response for skin, eye and inhalation exposure, taken from the safety data sheets rather than invented.

Incidents should be recorded and reviewed even when nobody is injured. A near miss with an unlabelled bottle is the cheapest warning you will ever get, and acting on it is far less expensive than the alternative.

If cleaning is outsourced, the occupier should be verifying these controls rather than assuming them. None of the requests below are unreasonable and all of them can be answered by a competent contractor within a few days.

Ask for the chemical register and the safety data sheets for every product that will be used in your building, and keep a copy on site. Ask where chemicals will be stored and confirm the space is suitable, ventilated and secure. Ask what training the attending staff have had on those specific products.

Then coordinate. Work health and safety law requires duty holders who share a workplace to consult, cooperate and coordinate. In practice that means a short conversation about storage, access, after-hours lone working and incident reporting before the first attendance, and a note of what was agreed.
