The right pharmacy drug safe size is one that holds all of your Schedule 8 stock at its peak, with every item inside compliant storage, plus room to grow. Measure your highest realistic holding, including opioid treatment program stock, returned medicines awaiting destruction and bulk deliveries before holidays, then choose a safe, or two, with internal space to spare. A safe that is full on an average day is already too small.
Capacity is a compliance issue, not just a convenience. Below we explain what regulators say about it, how to measure your stock, and when two safes beat one. For construction and fixing rules by state, see our pharmacy and clinic drug safe guide.
Why pharmacy drug safe size is a compliance issue
All S8 stock must be in compliant storage when it is not being used. If the safe is full and stock sits on a shelf or in a tote, that stock is non-compliant, however good the safe is. Victoria’s Department of Health guidance for pharmacists, published on the Victorian Pharmacy Authority website, says larger or additional cabinets or safes must be obtained if existing storage facilities cannot accommodate all Schedule 8 poisons. It also strongly advises employed pharmacists to inform the proprietor in writing if capacity is inadequate, and to keep evidence that they did. Our article on Victorian drug cabinet requirements covers the construction side.
Other states create the same pressure in different ways. Under NSW’s Medicine Storage Standards, from 5 November 2026, other scheduled medicines may not be stored with S8 and S4D medicines unless separately approved, apart from Schedule 9 substances and some refrigerated items. If Schedule 4 stock is filling your S8 safe now, you will need that space back. Our guide to the NSW S8 storage standards explains the full requirements.
What takes up space in a pharmacy safe
Pharmacists often underestimate volume because they think in units rather than boxes. List everything that must be in S8 storage overnight:
- Dispensing stock: tablets, capsules, patches and liquids in original packs, which you must generally keep in their packaging.
- Opioid treatment program stock: methadone and buprenorphine products, including liquids in bottles and injectables, which are bulky.
- Returned and expired S8 medicines: these remain your responsibility, and must be recorded and secured until destroyed.
- Owing and special orders: stock held for particular patients or awaiting collection.
- Seasonal peaks: extra stock ordered before Christmas closures, long weekends or supply shortages.
Opioid treatment program stock
Some states allow daytime storage of opioid treatment program stock outside the main safe, but not overnight. Queensland’s storage standard allows approved opioids in a lockable hardwood or metal cupboard or drawer under the personal supervision of a pharmacist during operating hours, but outside those hours they must go back into a compliant S8 safe. South Australia’s Code of Practice has a similar daytime allowance for MATOD drugs. Your safe has to hold the full overnight quantity. Our article on Queensland S8 storage standard sets out the other alternatives.
How to measure what you need
- Pick a peak day, such as straight after a large wholesaler delivery before a long weekend.
- Take everything out of the safe and arrange it on a bench the way you would like it stored, grouped by product and strength.
- Measure the total footprint and the tallest item, especially bottles and boxed injectables.
- Add space for returned stock awaiting destruction and for one or two new lines.
- Leave clear spare capacity, at least a free shelf, so a supply shortage or a new program does not push you over.
- Compare your total with each safe’s internal dimensions and shelf spacing, not its external size.
Shelf layout matters as much as volume. Adjustable shelves, internal drawers or lockable compartments make it easier to separate stock and reduce picking errors, which also helps when reconciling the register.
One large safe or two smaller safes?
| Factor | One large safe | Two smaller safes |
|---|---|---|
| Delivery and access | Needs clear access and may need specialist equipment | Easier through doors, stairs and lifts |
| Floor loading | Concentrated weight; check slab or suspended floor | Weight spread across two positions |
| Fitting in the dispensary | Needs a dedicated wall or corner | Can fit under benches or in two work zones |
| Fixing and keys | One set of fixings and one lock to manage | Two sets of fixings, keys or codes |
| Organisation | All stock in one place | Can separate fast-moving stock from reserve or OTP stock |
| Future growth | Must be sized for growth from day one | Add a second or third safe later |
In Western Australia, the choice is shaped by the regulations. Regulation 96 of the Medicines and Poisons Regulations 2016 requires S8 medicines in a pharmacy to be kept in a secure cabinet supervised at all times by a pharmacist, or in a large safe with a detection device, unless an alternative is approved. A large safe under Schedule 3 must weigh at least 250 kg, have at least two locking bolts of 32 mm diameter, be fixed to a concrete floor with an expanding bolt of at least 16 mm (unless it weighs more than 1 tonne), and be installed by a person licensed under the Security and Related Activities (Control) Act 1996.
Sizes in our range
Each brand offers several models at different sizes and prices. In our pharmacy drug safe range, Platinum’s PS series is listed from the PS1 at around $899 to the PS8 at around $6,193, and CMI offers the DS1, DS2, DS900, DS3, DS4 and DS5. For larger dispensaries, models such as the CMI DS4 digital drug safe are listed at around $6,479, and CMI’s MRS models go higher again. Prices change, so check the product page, and ask us for internal dimensions and construction details before you decide.
A used drug safe can be a cost-effective second unit if its specification and condition check out. Our guide on what to check before buying a used safe lists the essentials.
Installing in the dispensary
Plan the position before you order. The safe must be in a non-public area and fixed to the structure using your state’s method, which usually means bolting into a concrete slab or masonry. Leave room for the door to swing fully and for shelves to be reached without blocking a workstation. If the safe sits under a bench, fix it to the floor, not to the joinery.
Our team provides pharmacy drug safe installation, including heavy units. If you are upgrading, we can also handle removal of your old drug safe so it does not take up dispensary space.
Rules change and this article is general information only. Confirm your storage obligations with your state health department or pharmacy regulator before buying.
Frequently Asked Questions
What happens if our S8 stock no longer fits in the pharmacy safe?
Stock that does not fit is not compliantly stored. Victorian Department of Health guidance says larger or additional cabinets or safes must be obtained if existing storage cannot hold all Schedule 8 poisons, and it strongly advises employed pharmacists to tell the proprietor in writing and keep evidence that they did. Other states expect all S8 stock to be in compliant storage too.
Is it better to have one large drug safe or two smaller ones?
It depends on your floor, layout and stock. Two safes can be easier to deliver and fit under benches, and let you separate fast-moving stock from reserve stock. One large safe means fewer fixings and keys, but needs a strong floor and clear access. In Western Australia, the large safe specification also sets a minimum weight and licensed installation.
Do opioid treatment program doses need to fit in the safe overnight?
In Queensland and South Australia, yes. Queensland allows approved opioids in a lockable cupboard or drawer under pharmacist supervision during operating hours, but they must return to a compliant S8 safe outside hours. South Australia has a similar daytime allowance for MATOD drugs. Size your safe for full overnight stock, including bottles and injectables.
How do I measure how much space our S8 stock needs?
Empty the safe onto a bench on a peak day, such as after a large wholesaler delivery before a long weekend, and arrange the stock as you would want it stored. Measure the footprint and height, add space for returned stock awaiting destruction and for growth, then compare with each safe’s internal dimensions and shelf layout.
