  1. 2

  2. 3

  3. 5

  4. 7

The correct answer is: 3

Manifolded gas cylinders are utilized for various reasons, including ensuring a consistent and reliable gas supply, especially in facilities where large quantities of propane are needed. The correct answer indicates that up to three 100lb propane cylinders may be manifolded together for indoor use. This guideline is rooted in safety standards that are established to minimize risks associated with propane storage and usage indoors, such as preventing an accumulation of gas in case of a leak. By limiting the number of cylinders, the regulations help mitigate potential hazards, ensuring that the environment remains safe for those who are using the space. Adhering to these standards is vital for compliance with safety codes and regulations, such as those from the National Fire Protection Association (NFPA) and the relevant local regulations. Understanding and following these limits not only promotes safety but also ensures that gas fitters are performing their duties within the law while protecting the health of both workers and the public.
