Risks of single masks:
Single masks are still approved for nitrous oxide treat-
ments, but the following risks should be considered:
• It is difficult to ensure compliance with the nitrous
oxide occupational exposure limit values (refer to
Section 6. Safety and regular checks, (e.g. 100 ppm in
Germany, refer to trGS 900) are difficult with single
masks. that is why Baldus® does not offer single masks.
• For staff safety, the single mask system should no
longer be used (refer to Dr. Brigitte Mohr, Lachgasan-
wendung in der Zahnheilkunde [Use of nitrous oxide
in Dentistry], 2014).
Delivery of gas cylinders
Gas cylinders can be obtained from Baldus medizintech-
nik GmbH.
to place a gas order:
tel.: 0049 261/ 96 38 926-0
fax: 0049 261/ 96 38 926-21
email: gas@baldus-medizintechnik.de
Use tested compressed gas cylinders only! for a decen-
tralised nitrous oxide system, order at least two 10-litre
oxygen cylinders and one 10-litre nitrous oxide cylinder
for safety reasons. the nitrous oxide cylinder must be
stored upright.
Always keep a spare oxygen cylinder on hand!
for a centralised gas supply, the gas cylinders and equip-
ment are located in a separate room and the gas flows to
the treatment rooms through medical copper pipes. Bal-
dus medizintechnik GmbH, which is ISo 13485 certified,
can also install a centralised gas supply; 50-litre cylinders
are usually used.
the cylinders must stand securely and be protected from
tipping over using straps, for example (e.g. on a cylinder
trolley with straps, see photo).
Connecting pressure reducers
to the gas cylinders
It is not possible to mix up the nitrous oxide and oxy-
gen pressure reducers to the cylinders when connecting
them, as the connectors have different kinds of threads.
Keep the cylinders and pressure reducers free of oil and
grease and neVer use tools to tighten them. tightening
by hand is sufficient.
Do not open the cylinders too quickly, as otherwise the
pressure exerted on the pressure reducers and o-rings
may be too strong and these may have to be replaced
sooner. Spray the pressure ports with a leak detection
spray (solution of soap and water, see Accessories) to
identify any leaks.
