3. Areas of Caution
• The burner should not be used in areas where
there is a strong draught, as this may cause the
flame to be extinguished unintentionally.
• Laboratory burners must only be used under
constant supervision. After finishing work,
the gas supply to the burner must be shut off
(shutoff valve; disconnection from the gas
main).
• When used in classrooms, laboratory burn-
ers may only be put into operation after first
switching on the upstream shutoff devices,
such as central shutoff for the entire room,
group shutoff device and shutoff valve.
• For installation and operation of gas systems
in labs and science lecture rooms the regula-
tions in the DVGW Worksheet G621 (German
regulations) must be heeded.
• After use, the gas supply should be shut off
immediately via the shutoff valve, or, by sepa-
rating the gas connection safety valve.
• If there is a strong smell of gas, close the gas
shutoff valve immediately and take safety pre-
cautions (see DVGW regulations).
• Always observe the accident prevention regula-
tions of the relevant employer's liability insur-
ers.
• Never use water or compressed air to rinse or
blow out burners! This could flush out / blow
out the sealant grease causing the burner to
leak.
