In a Class I Division 2 location, flexible conduits are permissible under specific circumstances primarily to manage hazards associated with the presence of flammable gases or vapors. Utilizing flexible conduits only when necessary, such as at points of movement like motors, ensures that both safety and flexibility in installation are balanced. This practice minimizes the risk of spark generation or damage to electrical components, adhering to safety standards.

Flexible conduits provide the advantage of accommodating movement and vibration, which is crucial in areas where equipment like motors or pumps may need mobility. However, they should not be used indiscriminately or as the primary method of wiring. This selective application reduces the potential hazard posed by the environment while ensuring that electrical installations can still meet operational demands.

While avoiding flexible conduits entirely might seem safer, in practice, the controlled use at designated points meets the necessary safety guidelines without sacrificing functionality. Reinforcement with metal or professional installation are not universally required or feasible for every situation, which further supports the importance of using flexible conduits selectively.
