What is an important consideration before opening the tank of a compressed-air sprayer?

Releasing the pressure or using the pressure release valve before opening the tank of a compressed-air sprayer is crucial for ensuring safety. Compressed air can create high pressure in the tank, which if released abruptly can pose a risk of injury. By releasing the pressure beforehand, you minimize the risk of hazardous sprays or splashes and prevent sudden escapes of pressurized air that could potentially cause accidents or damage.

Opening a tank while it is still under pressure could lead to a dangerous situation where the contents could spray unexpectedly, potentially injuring the operator or others nearby. By following proper procedures such as using the pressure release valve, you enhance safety and maintain control over the sprayer's operations.

While it’s also important to perform tasks like checking for damage or removing the nozzle, those steps are secondary to ensuring that the pressure is safely released first. Taking the correct approach to managing pressure helps ensure a safe and effective pesticide application process.
