MCC-NH Gas Fitters Practice Exam

What is the main purpose of using marker tape in gas piping installations?

1. To enhance structural integrity

2. To indicate the location of gas pipes

3. To prevent leaks

4. To assess depth of soil

The correct answer is: To indicate the location of gas pipes

The main purpose of using marker tape in gas piping installations is to visually indicate the location of gas pipes. This practice is crucial for safety and maintenance reasons. Marker tape is generally placed above underground gas pipes and serves as a warning to identify the presence of gas lines, guiding excavators and other professionals to avoid accidental damage during digging or construction activities. This helps to prevent severe hazards like gas leaks and potential explosions, ensuring that individuals are aware of the buried utilities they should avoid. While improving structural integrity, preventing leaks, and assessing soil depth are important aspects of gas installations, these do not directly align with the primary function of marker tape. The tape's primary role is to communicate the presence and positioning of the pipes beneath the surface, thus promoting safety in the vicinity of gas installations.
