2.5.1. Surgical environment: prevention of
explosions/combustion
Sparks fly during proper use of the HF device.

Do not use the HF device in areas where there is a risk of
explosion.
 Do not use any flammable or explosive liquids.

If display components fail, do not use the HF device any longer.
 Avoid using ignitable anesthetics and gases which support
combustion (e.g. nitrous oxide, oxygen) during operations (e.g. in
the head and thoracic regions)
.

Wear suitable gloves during operations.
 Use exclusively non-flammable cleaning agents, disinfectants and
solvents (for adhesives). If you use flammable cleaning agents,
disinfectants or solvents, ensure that they have fully evaporated
before using the HF surgical equipment.

Ensure that no flammable liquids collect beneath the patient or in
body cavities (e.g. the vagina). Suction and/or flush body cavities
before activating the device.
 Wipe off all liquids before using the HF device.

Ensure that no endogenous gases are present that could ignite.
 Ensure that all materials saturated with oxygen (e.g. cotton, gauze)
are removed far enough from the HF environment that they cannot
ignite.
2.5.2. Application of the neutral electrode
Please read and comply with the notes about using the neutral electrode
listed in the user manual as well as the information on the packaging of
the neutral electrode.
In the monopolar HF method, the neutral electrode feeds the current
introduced into the patient's body at the surgical site back to the HF
device.

To prevent a rise in temperature at the current emergence point,
the following conditions must be ensured:

sufficiently large contact surface between the neutral
electrode and the patient's body

high electrical conductivity between the neutral electrode
and the patient's body
