Have you just bought a corrosive storage cabinet or installed a chemical storage container outdoors? Then this blog is written specifically for you. If you’re new to dangerous goods storage, you may not know that cabinets and outdoor storage containers require regular inspections, housekeeping and maintenance in order for them to stay safe — and meet your ongoing compliance obligations. But what do you need to tick off when inspecting your corrosive chemical stores?
From the stacking of your corrosive packages to the emptying of your spill sump, we’ll detail the general points you need to consider when developing a checklist for your corrosive cabinet inspections.
There are many factors that can inhibit and reduce the state-of-the-art controls that are featured in your corrosive storage cabinet or outdoor chemical storage container.
Regular use, accidental damage, changes in workplace practices and even changes in inventory may affect how your cabinet is operating and undermine its safety.
Developing a checklist for your controls with your team allows you to actively ensure compliance in handling and storage areas.
While your store may be 100% compliant when it leaves the manufacturer, the process of installing, using and cleaning the equipment may or may not be compliant.
By regularly inspecting your safety cabinets and outdoor chemical stores, you are ensuring that they are in good working condition and continuing to meet the requirements of WHS Regulations and Australian Standards.
This is true, regardless of whether they’re corrosive cabinets or another type of dangerous goods cabinet. All controls must be inspected, reviewed and maintained to achieve ongoing chemical compliance.
Section 37 of the WHS Regulations, it explains your duty in regard to maintaining chemical controls for hazardous substances:
37 Maintenance of control measures
A duty holder who implements a control measure to eliminate or minimise risks to health and safety must ensure that the control measure is, and is maintained so that it remains, effective, including by ensuring that the control measure is and remains:
(a) fit for purpose; and
(b) suitable for the nature and duration of the work; and
(c) installed, set up and used correctly.
To ensure that your corrosive stores are functioning as they should, regular inspections (preferably weekly, at a minimum) are required to maintain safety and chemical compliance.
In the next section, we’ll be explaining the key points that you should incorporate in your corrosive substance store inspection checklist.
Has the cabinet or store been installed correctly? An incorrect installation can result in a range of safety issues including spillage and the release of hazardous vapours.
Inspecting the installation of your cabinet or container is part of your compliance obligations.
Without a compliant cabinet or store installation, you won’t be able to maximise the effectiveness of the chemical controls that are built into your corrosive substance store.
Check these points on your next inspection:
IMPORTANT: We recommend conducting an onsite risk assessment before you purchase and install a corrosive cabinet or outdoor corrosive container. It’s vital that any potential hazards are noted and dealt with before you install your dangerous goods storage equipment.
The integrity of your store will be determined by how it was delivered, installed and used by your staff.
As part of your regular cabinet or store inspections, check for obvious signs of damage or wear by checking that
As corrosive substances can degrade materials including sheet steel, protection within indoor cabinets and outdoor stores is vital.
As corrosive cabinets feature chemically-resistant PVC linings, you must inspect these to ensure that they remain effective.
When inspecting your corrosive stores, make sure that your:
For cabinets that are made of polyurethane, make sure that the material is
REMEMBER: When it comes to the storage of corrosive substances in cabinets, there are two options available: metal and polyurethane. Highly corrosive chemicals are generally stored in poly cabinets to avoid the degradation of construction materials due to corrosive vapours.
While segregating dangerous goods from other incompatible classes is part and parcel of chemical storage, Class 8 corrosives must also be segregated in terms of acids and bases (including alkali).
Make sure that your inspection checklist ticks off:
If your chemical packages are stored in a dangerous or haphazard fashion, there is a real risk that the packages may fall, become damaged, and cause a corrosive chemical spill.
How you use and store your corrosive chemical packages can impact the likelihood of a chemical spill.
To make sure that your staff are following the correct stacking and loading procedures, inspect the store to ensure that:
Developing a strong strategy for housekeeping is an important part of maintaining a chemically compliant workplace.
As part of your regular inspections, check that the following tasks have been completed by your housekeeping team:
Also consider that:
IMPORTANT: While inspecting and maintaining your chemical controls is part of your duty under WHS Regulations, so is the review of your controls. Make sure that your team review your existing chemical control measures to ensure that they stay efficient and effective as your workplace grows and changes.
While we’ve highlighted some of the most important points to include in your inspection checklist, you can always tailor your list to include other factors that may be unique to your workplace. We also strongly recommend familiarising yourself with the WHS Regulations and Australian Standards to ensure that you’re continually meeting your compliance obligations.
