What is a proper action when a sprayer malfunctions?

• A. Release pressure and move to repair area
• B. Increase pressure and continue spraying
• C. Add more chemical
• D. Disassemble nozzle without releasing pressure

Answer: (A)

Releasing the pressure before addressing a sprayer malfunction is the safest first step. When you relieve pressure, the spray stops and the chances of a sudden, uncontrolled release of chemical or a nozzle/pipe burst are greatly reduced. This protects you from exposure and prevents further damage to the equipment. After the unit is depressurized, move to the repair area and perform troubleshooting or repairs according to the manufacturer’s instructions, ideally with the system still off and properly tagged out.

The other options aren’t appropriate because increasing pressure and continuing to spray can worsen the malfunction and create dangerous leaks or projectiles; adding more chemical wastes product and raises exposure risk; and disassembling a nozzle or other component while the system is still pressurized can cause a sudden, dangerous release of spray.
