What is the importance of wind review before deployment indoors?

• A. Always spray toward fans to distribute evenly.
• B. Close all doors to keep spray contained.
• C. In indoor spaces, avoid spray where ventilation could spread irritant to others; ensure proper ventilation.
• D. Spray in short bursts regardless of ventilation.

Answer: (C)

Indoors, air moves with vents, fans, and doors, so any spray will ride those currents. Before deploying a spray indoors, you assess how the air is moving and whether it could carry irritant toward bystanders or into occupied areas. If the ventilation could spread the irritant, you choose to delay, reposition, or adjust the environment to minimize exposure, and you aim to create or use ventilation in a way that helps dissipate the spray after deployment. This protects both you and others from unintended exposure and reduces the chance of the irritant circulating back toward people.

Spraying toward a fan, attempting to contain by closing doors, or spraying in short bursts without considering how air is moving can all increase risk by pushing irritant toward others or trapping it in the space.
