10.3.2.3 Safety Precautions

The materials used in the gas supply system have to be chosen in accordance
with the reactive gases used. Also, technical precautions for pressurized
systems need to be taken into account. Leaks in the gas supply system can
be automatically monitored using gas-specific sensors, pressure transduc-
ers, and smoke detectors. Limiting access, remote control systems, and an
