Sustainable DEF storage solutions

Work sites have many environmental quotas to meet, being careful to avoid toxic spillages and creating minimal environmental impact. This is, after all, why DEF is widely used today. 

DEF is not a toxic solution and leaves little environmental damage if spilt, but you still want to avoid leaks where possible. Having a bunded DEF tank ensures your fluid does not have any environmental impact.  That’s why the DEFCube has an inner tank, providing that extra protection.

Regulations for storing DEF

There are currently no storage regulations for DEF in the UK. However, the Environmental Agency under the anti-pollution work regulations, has issued storage guidelines enforcing proper equipment suitable for use with urea, this includes having secondary containment for the container and ancillary equipment, for example a bunded tank.

Storage of DEF Fluid FAQs

How should DEF be stored securely?

Due to its corrosive nature DEF must be stored in high-density Polyethylene, polypropylene or stainless steel containers. This will enhance the shelf life of your asset by keeping it away from environmental conditions such as heat and dust.

How long can def fluid be stored in a tank?

This is largely dependant on the ambient storage temperature, DEF will degrade over time depending on temperature and exposure to sunlight. As a guide, non-contaminated DEF that conforms to ISO22241 standard and stored within the optimal temperature conditions, should have a shelf life of up to 2 years.

Do DEF tanks need secondary containment?

There is not a requirement for DEF storage to need secondary containment, however it is advised in order to reduce contamination risk and the risk to the environment as DEF is corrosive and a pollutant.
