While this might seem like a practical and efficient approach, chemical storage requires far more consideration.
One of the most important factors is the risk of chemical incompatibility, which can turn a simple storage decision into a serious safety hazard.
What is chemical incompatibility?
Many chemicals remain stable and unchanged for long periods, especially when stored correctly in their original packaging.
However, containers can weaken or fail for many reasons, and this can cause a loss of containment and a chemical spill.
If a spilled chemical comes into contact with residues, other products or reactive materials, it may undergo a reaction.
When that reaction releases flammable, corrosive or toxic gases, or generates heat or oxygen that can ignite or intensify a fire, this is known as a chemical incompatibility.
These reactions can escalate quickly and significantly increase the severity of an incident.
How can I identify a chemical incompatibility?
Chemical incompatibilities are well documented.
The most reliable place to find incompatibility information is in Section 10 of a product’s Safety Data Sheet (SDS). Because checking every SDS can be time-consuming, many workplaces use chemical storage incompatibility charts as a practical starting point.
Common examples in the agricultural and veterinary chemical sector include phosphine products with water, acidic products with alkaline products, certain insecticides with alkaline products, and oxidising agents such as nitrates with organic materials.
What should I do if I notice a chemical incompatibility?
Check the product’s Safety Data Sheet to confirm the issue. If you notice a hazardous combination or are unsure, speak with your branch manager or supervisor.
During an Agsafe premises assessment, the facilitator can provide advice, and support is also available through memberservices@agsafe.org.au.
Once an incompatibility has been confirmed, relocate the chemicals carefully to a safer storage area.
Why is managing chemical incompatibilities important?
A safe workplace relies on thoughtful planning and sound chemical management.
Storing chemicals without considering compatibility increases the risk of fires, toxic gas releases, spills and other dangerous incidents.
By organising storage areas and seeking advice when needed, businesses can reduce the likelihood of an incident and minimise its severity, protecting workers and the wider community.
