Houston Fire Department
Engineer/Operator - 2016
Sample Test

Following are 20 multiple-choice questions. Select the best answer for each question.

Each question in this sample test is based on one of the sources in the Official Book List for the Engineer/Operator's examination. Answer each question based on the text or document from which it was taken. Following each question, in bold face, is the page and paragraph or section from which the question was taken.

The test preparation workshop for the Engineer/Operator's Examination will consist of five original practice tests averaging 100 questions. Three of the tests will be administered in class under realistic test conditions and two tests will be given via the Internet.
