During public access hours, what must be ensured regarding propane cylinders in a building undergoing renovations?

In a building undergoing renovations, ensuring that propane cylinders cannot be left unattended during public access hours is crucial for safety. Propane cylinders are pressurized and can pose significant hazards if mishandled or improperly secured. By requiring that they not be left unattended, the risk of unauthorized access or tampering is minimized, which is essential to prevent accidents or incidents that could arise from an unmonitored situation.

While storing cylinders in locked areas or ensuring that they are monitored continuously can also enhance safety, these measures alone do not replace the fundamental requirement of constant oversight in a public space. Furthermore, having cylinders connected at all times is not a standard safety practice, as there are instances when cylinders must remain disconnected for operational or maintenance reasons.

Overall, the focus on preventing unattended cylinders during public hours is about maintaining a secure and safe environment for both workers and the public.
