Using diesel exhaust fluid, or DEF, is crucial to reduce emissions in diesel engines. However, it’s important to follow all safety rules and regulations regarding the storage, transportation, and use of this fluid in extreme environments. The Arizona desert is arid, hot, and dusty and most industrial areas and job sites get excessive sun exposure. This could result in dangerous health and safety hazards related to storing and using DEF. At Grohall, we want to provide our customers with the most up to date information about safely using the tools, equipment, and liquids needed in their industries. Here is our guide to safely using DEF in the desert. 

Choose the Right Product

The only DEF you should use is one that meets ISO 22241 standards and bears the API certification mark. While there is no specific type of DEF that is rated for hot climates, you should ensure you only choose a product that meets the universal standard. 

Properly Store DEF

The storage of DEF is regulated by the U.S. Environmental Protection Agency. It must be stored in a cool, dry place out of direct sunlight. The temperature of the storage environment must be between 12-86 degrees Fahrenheit. Only store DEF in approved containers made from stainless steel or HEDP. All transfer equipment must also be compatible to prevent contamination and corrosion. Keep the area around the storage tank and transfer equipment clean and clear and keep storage containers closed tightly.

Regularly Inspect Storage Containers and Fluid

Before transporting or using DEF, inspect it for safety and quality. You should also inspect the storage containers and fluid regularly to catch early warning signs of problems, like leaks or contamination. DEF should be clear and colorless. If the fluid is cloudy or discolored, it may be contaminated and should be disposed of. 

Maintain Your DEF Systems

You should also regularly inspect and maintain your DEF systems. You should plan to replace DEF filters after 3,000-5,000 hours of operation. You should regularly inspect the DEF pump and injector and replace them if they become clogged or damaged. Monitor fluid levels regularly, as running out of DEF can cause damage to the engine and cause downtime or inefficiencies.

Be Prepared for the Heat

DEF will degrade faster when it is exposed to high temperatures and direct sunlight. While the SCR system of your vehicle or equipment is designed to protect DEF from sun exposure and heat, you must take care when storing DEF that it isn’t exposed to prolonged temperatures over 86 degrees Fahrenheit. If it is, its shelf life may decline from two years to six months.
