"To work in this field, you need a solid technological background and you have to know the building codes," says inspector Don Lopes.

You are inspecting a recreation center. You've discovered a heating duct that is only 10 feet above the floor and is unprotected. Some changes will have to be made. Below is a portion of the electrical code that deals with heating fixtures. Find the section that refers to the problem with the heating duct and explain it in simple terms to the manager of the recreation center.

Electrical Code
Section 62-110: Installation of Fixtures

1) Fixtures shall be installed so that:

a) The proper radiation of heat shall not be obstructed by any portion of the building structure;

b) Adjacent combustible material shall not be subjected to temperatures in excess of 90 degrees C.

2) Where a fixture is recessed in non-combustible material in a building of concrete, masonry or equally non-combustible construction, the non-combustible may be subjected to temperatures not exceeding 150 degrees C, but the fixture shall be plainly marked as suitable for the service.

3) Where fixtures are installed less than 16.5 feet above the floor in an arena, gymnasium, or similar location, where they may be exposed to damage from flying objects, the heating elements shall be of the metal sheathed type or the fixture shall be suitable for the application.
