2FIRSTAIDFORELECTRICAL SHOCK AND SAFETY
RULES
2.1 FIRST AID FOR ELECTRICAL SHOCK
Do not touch the bare hands until the circuit has been opened. pen the circuit by switching off the line
switches. If that is not possible protect yourself with dry material and free the patient from the con-
ductor.
2.1.1 Artificial respiration
It is important to start mouth resuscitation at once and to call a doctor immediately. suggested procedure
for mouth to mouth resuscitation method is described in the Tab.1.
2.1.2 Treatment of burns
This treatment should be used after the patient has regained consciousness. It can also be employed while
artificial respiration is being applied (in this case there should be at least two persons present).
Warning
• Do not attempt to remove clothing from burnt sections
• Apply dry gauze on the burns
• Do not apply ointments or other oily substances.

MN.00273.E - 004 9
Tab.1 - Artificial respiration
Step Description Figure
1
Lay the patient on his back with his arms parallel to the body.
If the patient is laying on an inclined plane, make sure that his
stomach is slightly lower than his chest. Open the patients
mouth and check that there is no foreign matter in mouth (den-
tures, chewing gum, etc.).
2
Kneel beside the patient level with his head. Put an hand under
the patient’s head and one under his neck.
Lift the patient’s head and let it recline backwards as far
as possible.
3
Shift the hand from the patient’s neck to his chin and his
mouth, the index along his jawbone, and keep the other fingers
closed together.
While performing these operations take a good supply of oxy-
gen by taking deep breaths with your mouth open
4
With your thumb between the patient’s chin and mouth keep
his lips together and blow into his nasal cavities
5
While performing these operations observe if the patient’s
chest rises. If not it is possible that his nose is blocked: in that
case open the patient’s mouth as much as possible by pressing
on his chin with your hand, place your lips around his mouth
and blow into his oral cavity. Observe if the patient’s chest
heaves. This second method can be used instead of the first
even when the patient’s nose is not obstructed, provided his
nose is kept closed by pressing the nostrils together using the
hand you were holding his head with. The patient’s head must
be kept sloping backwards as much as possible.
6
Start with ten rapid expirations, hence continue at a rate of
twelve/fifteen expirations per minute. Go on like this until the
patient has regained conscious–ness, or until a doctor has as-
certained his death.

2.2 SAFETY RULES
When the equipment units are provided with the plate, shown in Fig.1, it means that they contain compo-
nents electrostatic charge sensitive.
Fig.1 - Components electrostatic charge sensitive indication
In order to prevent the units from being damaged while handling, it is advisable to wear an elasticized band
(Fig.2) around the wrist ground connected through coiled cord (Fig.3).
Fig.2 - Elasticized band
Fig.3 - Coiled cord
The units showing the label, shown in Fig.4, include laser diodes and the emitted power can be dangerous
for eyes; avoid exposure in the direction of optical signal emission.

• ISP high capacity and performance, for LAN-to-LAN connections
• emergency wireless links
• zero footprint applications
ALFOplus doesn’t need any indoor unit; power supply can be directly by POE+ through the data cable or
through a dedicated auxiliary port. It’s available 1+0 or 1+1 radio system configurable via software fol-
lowing two versions of ALFOplus:
• Electrical Gigabit Version
- LAN1 - 1x10/100/1000BaseT traffic and/or supervision port with clock, synchronism recovery
and PoE
- LAN2 - 1x10/100/1000BaseT supervision and/or traffic port with clock and synchronism recov-
ery
• Optical Gigabit Version
