Texas CNG(Compressed Natural Gas) Driver Practice

What must every installed hose be protected against?

1. Mechanical damage

2. Water exposure

3. Corrosion

4. Temperature changes

The correct answer is: Mechanical damage

Every installed hose must be protected against mechanical damage to ensure its integrity and safe operation. Mechanical damage refers to any physical impact or strain that may compromise the hose's structure, leading to leaks or failures. This protection is crucial because hoses are often subject to various forces such as abrasion from movement, pressure variations, and potential contact with sharp objects or heavy equipment. Without proper protection against mechanical damage, hoses can wear out prematurely or suffer catastrophic failures, which could result in hazardous situations, especially in environments where compressed natural gas is being transported or utilized. Ensuring that hoses are adequately shielded from such risks helps maintain safety and effectiveness in CNG applications. While water exposure, corrosion, and temperature changes can also affect hoses, the primary concern during installation and operation is the potential for immediate physical damage that could jeopardize the entire system's safety and functionality.
