You're loading compressed gas cylinders on a flatbed. According to federal requirements, how must the cylinders be secured?

Accepted Answer

Upright or horizontal, securely restrained against shifting, overturning, or ejection; if loaded horizontally, positioned so the pressure relief device stays in communication with the vapor space
