STAFFORD COUNTY, Va. (WJLA) - Four students were transported to the hospital after a contractor sprayed herbicide too close to air vents at a high school.

Stafford County Fire and Rescue units responded to North Stafford High School in the Garrisonville District just after 10 a.m. Tuesday after the school reported several students said they felt ill due to a strange odor in the school.

Fire Rescue personnel investigated and determined that a contractor had sprayed herbicide near the fresh-air intakes for the school's HVAC system in one wing of the school.

That wing of the school was immediately evacuated.

Fire and Rescue personnel examined 17 ill-feeling students. Four of the students were transported to the hospital for further evaluation.

After consulting with the State Hazardous Material Officer, Fire and Rescue personnel ventilated the affected area and the school returned to normal operation at 1 p.m., officials said.
