ŹAfter use, the gas supply should be turned off immediately via the gas shut-off valve at the
laboratory workbench (gas isolation valve) or by separating the gas connection safety valve.
ŹIn classrooms, laboratory burners may only be used after turning on all the lined up shut-off
systems (central room shut-off, group shut-off system, shut-off valve).
ŹClose attention must be paid to the DVGW worksheet G 621 (German legislation) when instal-
ling and using gas apparatus in laboratories and science classrooms.
ŹShould a strong smell of gas be detected, close the gas shut-off valve at the laboratory work-
bench immediately and initiate the corresponding safety measures (see DVGW law and valid
national regulations).
ŹAlways pay attention to the accident prevention regulations stipulated by the respective trade
organisations!
ŹFurther information concerning connection and operational regulations can be obtained from
your local gas supply company and from your local gas installation specialist.
ŹNever clean the burner using boiling water or with compressed air!
