A man was rescued from a cement truck tanker in Kapolei Friday morning, according to fire officials.
The middle-aged man was performing routine work inside the tank when he felt too weak to climb back out, possibly due to the heat.
Fire officials say the temperature inside was 107 degrees Fahrenheit.
"He was very weak. Definitely unable to climb out on his own. He wasn't feeling too great," Honolulu Fire Battalion Chief Ken Lee. "Before rescue even came, we were able to drop oxygen down to him with a mask and instantly he said he felt better."
Firefighters set up a type of pulley system to hoist the man out of the tank. He was transported to a local hospital to be checked out.
