True or False? An acetylene manifold should not exceed 15 psi.

An acetylene manifold should not exceed 15 psi because acetylene is a highly flammable gas, and exceeding this pressure can be dangerous. Acetylene is a unique gas in that it becomes unstable at pressures above 15 psi; high pressures can lead to explosive polymerization. For safety standards, it is vital to keep the pressure within this limit to prevent potential hazards associated with storage and use. This regulation is guided by safety protocols to ensure that acetylene is handled correctly and prevents accidents in work environments where acetylene is utilized, such as welding or cutting applications.
