Which statement accurately reflects ULV engine compatibility?

• A. ULV applications must use gasoline engines.
• B. ULV applications can use gasoline engines.
• C. ULV applications cannot use gasoline engines.
• D. ULV applications have no engine restrictions.

Answer: (C)

Power source safety is the key issue with ULV spraying because these applications create very small droplets and often use flammable solvents. Gasoline engines can ignite vapors through sparks, heat, or exhaust, which makes them unsafe for ULV equipment. To minimize fire risk, ULV machines are typically electric- or battery-powered rather than gasoline-powered. That’s why gasoline engines are not compatible. Statements suggesting they must use gasoline, can use gasoline, or have no engine restrictions conflict with this safety requirement.
