What is the capacity, in gallons, of the backpack used for spraying?

• A. 2 gallons
• B. 3 gallons
• C. 4 gallons
• D. 5 gallons

Answer: (C)

Understanding equipment capacity helps you estimate how much solution you can carry and how often you’ll need to refill, which impacts coverage time and how easily you can move during spraying. For the backpack used in spraying, the capacity is four gallons. This size provides enough solution to treat a typical area before refilling while keeping the weight manageable for a technician to carry on a route. If it were smaller, like two gallons, you’d refill more often and slow down; if it were larger, like five gallons, the added weight could become tiring over a day. A three-gallon option exists but four gallons strikes a common balance between coverage and portability.
