What is the purpose of restricting access to certain appliances?

Restricting access to certain appliances is primarily intended to ensure safety and prevent tampering. This practice is crucial in settings where gas appliances are involved because unauthorized access can lead to misuse or mishandling, which poses significant hazards, including gas leaks, explosions, or fires. By controlling access, gas fitters can help maintain safe operational environments and ensure that only qualified personnel can perform necessary maintenance or adjustments on these devices. This policy supports compliance with safety regulations and promotes public safety, highlighting the importance of maintaining strict control over who can interact with potentially dangerous equipment.
