How many spare compressed tanks (oxygen/acetylene) can be stored at a location?

The correct choice regarding the number of spare compressed gas cylinders that can be stored at a location reflects safety regulations and best practices for handling compressed gases like oxygen and acetylene. Storing only one spare cylinder of each type is in line with safety guidelines designed to minimize hazards associated with the handling and storage of pressurized gases.

By limiting the number of spare tanks, the risks associated with leakage, handling accidents, and potential fire hazards are significantly reduced. Managing the inventory of these materials also helps ensure that proper ventilation and safety measures are maintained, which are critical when working with volatile substances. Additionally, having a single spare allows workers to have the necessary resources without overwhelming the storage area with excess equipment that might lead to safety hazards or compliance issues.

In contrast, options suggesting a higher number of tanks may lead to an unsafe working environment, as they could exceed the capacity that can be safely managed in a given area, resulting in increased risk and potential violations of safety regulations.
