What must be on when spraying ULV?

• A. A warning beacon
• B. A safety light
• C. A siren
• D. A flag

Answer: (A)

When applying ULV aerosols, visibility and warning to others are essential because the fine droplets can drift and affect bystanders. A warning beacon on the spraying equipment is required to signal that application is in progress, helping to prevent exposure and keep nearby people and vehicles aware of the operation. This is the standard safety signal used during pesticide applications to communicate ongoing spraying. The other options don’t fit as a routine warning during ULV spray. A siren is disruptive and not typically used for standard applications. A flag marks a fixed area and isn’t practical for ongoing spraying. A safety light might be used in some contexts, but the specific, widely recognized requirement is a warning beacon that clearly indicates spraying is happening.
