Pest ControlQuestion 191 of 319
An air curtain (a downward stream of high-velocity air installed above a doorway) is used in food facilities to:
a.Replace the need for a self-closing door and door sweep
b.Cool food faster after cooking
c.Block flying insects from entering through a frequently used door when it must remain open
d.Apply pesticide as customers walk through
Explanation
Air curtains create a downward jet of air that discourages flying insects from entering through doors that are opened often (deliveries, dining patios). They supplement — but do not replace — tight-fitting self-closing doors, screens, and door sweeps. Air curtains do not contain pesticide.
