Always leak-test any manifold or distribution pipeline before using.
Always be sure that the gas in a pipeline is the correct gas for the intended use.
Always close all cylinder valves before disconnecting cylinders from a manifold.
Always test cylinders to be sure the cylinders are full before connecting to a manifold.
All gas distribution piping systems must meet the appropriate industrial standards for the intended service
and must be thoroughly cleaned before using. For the United States, some applicable safety rules and
precautions are listed below:

INSTALLATION
Keep all cylinders and manifolds away from any source of high temperature over 120°F (50°C) or possible
fi re hazards. High-pressure gas contained in a closed cylinder becomes increasingly dangerous when
exposed to high temperature because pressure increases and the strength of the cylinder decreases.
Manifolds installed in open locations should be protected from weather conditions. During winter, protect
the manifold from ice and snow. In summer, shade the manifold and cylinders from continuous exposure
to direct sunlight. Always leave access to the manifold for cylinder replacement.
The site chosen for the manifold installation shall be level, well ventilated, and at a safe distance from
sources of fl ames, sparks, and excessive heat. The manifold should not be placed in an area that may
subject the manifold to damage from passing trucks, cranes, or other heavy machines. Oxygen manifolds
must not be installed under shafting, belting, or other places where oil can drip on them. For other location
guidelines, see NFPA standard 51.
