Do you have some questions about Dangerous Goods storage? Our Field Auditors regularly speak with customers across the country, answering their questions on the safe storage of Class 3 Flammable Liquids and other Dangerous Goods. So, we thought we’d share our answers to some of the most popular frequently asked questions including, ‘Do flammable cabinets need to be anchored?’
Read on to find out how you can solve your flammable liquids storage issues — and understand your obligations when it comes to chemical compliance.
Good question! Right out of the box, so to speak, your focus should be on positioning your flammable cabinet in a compliant location in your workplace.
Not only do you have to select a location that’s convenient for your staff to access the flammable liquids, but your organisation must also abide by the requirements of the Australian Standard AS 1940:2017.
Let’s run through a few of the requirements, so you can decide on the best position for your cabinet.
The standard explains that:
Do you have cabinets over 850 L in capacity?
The additional requirements for larger capacity cabinets include:
REMEMBER: If the cabinet must be moved to a new location after the initial installation, you must ensure you’re meeting the cabinet installation requirements of AS 1940:2017. Don’t let unsupervised staff relocate a cabinet unless it’s been authorised by senior staff members who are trained in flammable liquids safety.
The short answer here is, ‘No’.
There are 9 Classes of Dangerous Goods, all with their own requirements for safe chemical storage. You should never mix classes of Dangerous Goods, as a violent chemical reaction is likely to occur.
While you must always follow the Dangerous Goods segregation chart and separate incompatible substances, you can store Class 2.1 or Class 2.2 Flammable Gases (and only that Class of aerosols, as Class 2.1 and 2.2 must be segregated by 3 m) in an flammable cabinet.
Let me repeat that: You can store Class 2.1 or Class 2.2 aerosols in a flammable cabinet — as long as it doesn’t house any Class 3 Flammable Liquids or other Dangerous Goods Classes (as they’re incompatible substances).
Keep in mind, two things must happen before you make this change. The first is that the cabinet needs to be thoroughly cleaned, so there is no chemical reaction once the new goods are placed inside. Second is that the Dangerous Goods diamond on the cabinet must be swapped over to Class 2.1 or 2.2 before you load the cabinet.
As stated in Section 3.7 of AS 1940:2017, aerosols must always be kept in a store that has projectile protection. This is to prevent the aerosols becoming dangerous projectiles in the event of a fire.
A compliant flammable cabinet has already been constructed to provide projectile projection, so it can therefore be used to store either Class 2.1 or Class 2.2 gases. However, it’s always a preferably option to store aerosols in an aerosol storage cage that’s made for that Class of Dangerous Goods.
IMPORTANT: As gases provide no spill risk, we recommend that they’re stored in a purpose-built aerosol storage cage. A cage is engineered to meet the requirements of AS 4332:2004 – The storage and handling of gases in cylinders and provides protection for high pressure aerosol cans.
Flammable liquids — such as paints, acetone, thinners, petrol and diesel — are volatile substance that can easily ignite in the presence of an ignition source.
As flammables can ignite at room temperature, they must be treated with the utmost care when they’re being handled, decanted, transferred or stored.
To reduce the risk of fire or explosion, combustibles should never be placed in a flammable liquids cabinet.
Combustibles should have their own designated storage solution — such as a filing cabinet for paperwork, or a dedicated cabinet for PPE.
Make sure that your staff don’t allow these types of materials in (or on top of) your flammable liquids storage cabinet:
Are you wondering where to store your Safety Data Sheets?
SDS storage or document storage boxes are specifically designed to provide the safe, durable storage solution for all your important chemical documents. You should attach a document holder to your flammable cabinet, so staff can quickly refer to your documents in the event of an emergency.
Whatever you do, don’t just leave these important documents lying around in your workplace. Not only are paper documents classed as combustible material, SDS must be easily accessible for all staff and contractors who deal with flammable liquids.
A compliant flammable cabinet is a risk control measure that’s been specifically designed and constructed to meet the requirements of AS 1940:2017.
In Section 4.9.4 of the standard, it explains that cabinet doors must be self-closing, close-fitting and held shut automatically by catches (at 2 or more points).
Therefore, your cabinet must have self-closing doors. But why?
There are several reasons that flammable liquids cabinets must be constructed with self-closing, tight-fitting doors.
This specific risk control measures provides a range of safety benefits including:
The last FAQ that we’ll be answer in this blog, is one that’s quite simple to answer. If you are using an outdoor flammable liquids store, then we always suggest that you anchor your cabinet. However, this isn’t a requirement of AS 1940:2017 – it’s simply our team’s recommendation for risk reduction.
The reasons for this, is that outdoor flammable liquids stores may suffer impact damage from a range of sources in the outdoor environment.
We recommend anchoring outside flammable liquids stores to avoid issues with cabinet instability.
Impact damage, such as a falling tree branch crashing onto your cabinet or a forklift running into your outdoor flammable liquids store, can cause serious cabinet damage and instability.
Outdoor cabinets are also exposed to the elements and may be subject to high winds.
By anchoring your outdoor flammable liquids store, you are reducing the risk of the cabinet toppling over or becoming unstable in the event of a storm, high winds or impact damage.
Our team at STOREMASTA construct flammable liquid stores that are already equipped with base plates. The cabinets can be easily bolted down and anchored to the spot — after you’ve decided on the right outside location.
As indoor cabinets don’t face the same risks as outdoor stores, the only reason you may choose to bolt down your indoor safety cabinet is if it’s deemed a risk control measure during your chemical risk assessment. In a general workplace situation, you shouldn’t have to anchor your flammable liquids cabinet if it’s installed in a safe and compliant location indoors (see FAQ #1 for more information).
If you’re still curious about how to correctly choose, install, set up and maintain a flammable cabinet, our team are here to help. We’ve also put together a helpful guide that will help you made the right decisions when you’re storing your Class 3 Dangerous Goods.
