What is a G3 technician permitted to do?

  1. Install new appliances exceeding 400k BTU

  2. Repair existing installations of appliances under 400k BTU

  3. Reactivate existing installations of appliances up to 400k BTU

  4. Conduct safety inspections on any gas appliance

The correct answer is: Reactivate existing installations of appliances up to 400k BTU

A G3 technician is specifically authorized to reactivate existing installations of appliances up to 400k BTU. This means they can safely turn on or restart appliances that have been previously installed and are functioning within the specified BTU limit. The emphasis on existing installations highlights that a G3 technician's role does not encompass new installations or repairs, but rather the safe reactivation of systems that are already in place. The requirements for handling gas appliances are based on safety regulations and technical competencies. Reactivating an existing installation ensures that the technician adheres to safety protocols and verifies the appliance's operational state before putting it back into use. This not only guarantees compliance with regulatory standards but also emphasizes the technician's responsibility to ensure the safety of gas systems before they are returned to service. By understanding the scope of a G3 technician's permissions, it's clear that they have a critical role in gas safety and efficiency without overstepping into areas that require more advanced qualifications.
