A 70-year-old Aiea man was seriously injured Monday afternoon after falling into a narrow hole about 30 feet deep in the backyard of his Waoala Place home, as reported by Hawaii News Now.

The Honolulu Fire Department received the 911 call at 4:08 p.m. on Monday, Nov. 9, reporting a man trapped in a hole behind the home at 99-405 Waoala Place.

HFD sent 17 units with about 24 personnel, and the first unit arrived at 4:17 p.m.

Firefighters described the hole as possibly an old cesspool, roughly 30 feet deep and only 15 inches wide.

The man was injured but conscious and able to talk with rescuers throughout the operation.

HFD Rescue and Hazardous Materials crews first tested the air inside the confined space to make sure it was safe to enter.

Rescuers then set up a rescue tripod, went down to assess and treat the man, and brought him up using rope rescue equipment, according to the Honolulu Star-Advertiser.

Honolulu Emergency Medical Services paramedics treated him at the scene and took him to an emergency room in serious condition.

Pearl City Local wishes him a full recovery.
