Improper distance control while administering OC can cause which effect?

• A. Optical distortion
• B. Hydraulic needle effect
• C. Thermal burn
• D. Suction effect

Answer: (B)

When OC spray is delivered too close, the spray doesn’t have time to break into a broad mist and instead becomes a narrow, high-velocity jet. This concentrated stream is called the hydraulic needle effect. It can penetrate more deeply into the eyes and mucous membranes and cause greater tissue irritation and injury. Proper distance helps disperse the spray and reduces the risk of this penetrating jet. Other effects like optical distortion or a general thermal burn can occur from OC exposure, but they aren’t specifically caused by being at an improper, too-close range in the same way the hydraulic needle effect is. The suction effect isn’t the recognized mechanism associated with distance control in OC spray.
