Which of the following is a risk factor associated with flex hoses?

Flex hoses are often used in gas piping systems for their flexibility and ease of installation. However, a significant risk factor associated with flex hoses arises when they are run through walls. This situation can lead to several potential safety hazards.

When flex hoses are installed through walls, there is an increased risk of damage or wear due to contact with structural elements or other materials. For example, if a hose rubs against a sharp edge or abrasive surface, it can become compromised, leading to leaks. Furthermore, walls can trap any escaping gas created by a leak, creating a dangerous build-up of flammable gas that could lead to an explosion or fire if ignited.

In addition, running flex hoses through walls may not be in compliance with building codes or safety regulations, which often require certain types of piping to be rigid and securely connected. Codes typically favor solid piping when transitioning between areas to ensure greater durability and safety.

By understanding the risks associated with flex hoses, especially when run through walls, proper precautions can be taken during installation to mitigate these dangers and ensure safe operation of gas piping systems.
