InterNACHI inspectors should: 1  check that a portable fire extinguisher exists within a 30-foot travel distance of commercial-type cooking equipment that uses cooking oil or animal fat. 2  check that a portable fire extinguisher is within 75-feet of travel on every floor. check for the presence of portable extinguishers, and determine that they are located in conspicuous and readily available locations immediately available for use, and not obstructed or obscured from view.
