Final answer:
A Fuels Safety Inspector from TSSA has the authority to enter buildings without advance notice to check compliance with fuel industry laws, ensuring safety and preventing hazards due to non-compliance.
Step-by-step explanation:
A Fuels Safety Inspector designated by the Technical Standards & Safety Authority (TSSA), indeed, has the authority to enter a commercial or industrial building without advance notice. This action is performed to ensure that fuel installations and the individuals working on these installations comply with the regulatory laws governing the fuel industry. The inspector's main responsibilities include conducting inspections, investigations, and audits, and their authority to do so without prior notice is a measure designed to maintain high safety standards and prevent potentially hazardous situations that could result from non-compliance.
