Ignite Success: Ace the 2026 MCC-NH Gas Fitters Exam!

Securing outlet fittings or piping is critical in ensuring safety and functionality in gas systems. The requirement for them to be securely fastened in place ensures that there is no movement or loosening over time, which could lead to leaks or failures in the system. This assurance of stability is vital for maintaining the integrity of the gas supply and preventing hazards associated with gas leaks.

When fittings and piping are not securely fastened, they may become loose due to vibrations, thermal expansion, or other factors, potentially resulting in dangerous situations. Therefore, strict adherence to securing these components is essential to prevent accidents and ensure a safe working environment.

Other options suggest less stringent measures, such as loose fastening or allowing for easy removal, which would compromise the stability of the system, making them unsuitable choices in the context of safe gas installation practices. The requirement for visibility through painting does not apply to the structural integrity needed for outlet fittings.
