3.6 Thunderstorm
Never work on high-voltage and AC or work on steel towers and masts in thunderstorms.
Thunderstorms generate powerful electromagnetic fields in air. Ground the equipment
properly to avoid thunder stroke.
3.7 Static Electricity
Static electricity generated in the human body may damage the electrostatic-sensitive parts on
the circuit board, such as large-scale integrated circuit (IC).
l
In dry climate, the electrostatic charge carried by the human body may go up to 30 kV.
The charge may remain in the human body for a long period. When an operator with
electrostatic charge contacts with an electrostatic-sensitive part, the electric discharge
may damage the part.
l
Before coming into contact with any equipment such as, hand-held plug-in boards,
circuit boards, or IC chips, wear an anti-static wrist strap with one end well grounded to
protect sensitive parts from static electricity on your body.
l
Before touching any board or module, discharge the static electricity in your body by
wearing an anti-static wrist strap.
l
Add a resistance of over 1M between the strap and the grounding point to protect
yourself from electric shock. The resistance over 1M is reliable in terms of electrostatic
voltage discharging. Check the anti-static wrist strap regularly. Never replace the cable
of the anti-static wrist strap with other cables.
Issue 01 (2007-01-24) Huawei Technologies Proprietary 5
Safety Precautions
iSite BTS3006C
Maintenance Manual
l
Prevent electrostatic-sensitive boards or modules from touching the object with static
electricity or the object that may easily generate static electricity. For example, when
rubbing on an object of insulating materials such as packing and conveyer, an
electrostatic-sensitive part takes electric charge. When touching a human body or when
connected to the ground, the discharge may damage the part.
l
Electrostatic-sensitive boards or modules should contact only good conductors, such as
anti-static packing bags. Pack the board with an anti-static bag for stock or transport.
l
Before connecting any measurement device to boards or modules, ground it to discharge
its static electricity.
l
Do not place boards or modules near strong DC magnetic field, for example, the cathode
ray tube of a scope. Keep a distance of 10 cm at least.
l
The damage caused by static electricity is accumulative in effect. If the damage is slight,
the part does not fail. However, as the damage occurs repeatedly, the part may suddenly
fail. The damage caused by electrostatic discharge on the part may be explicit or implicit.
The implicit damage is not visible. However, it makes the part vulnerable to over-voltage
and high-temperature.
Figure 1 shows how to wear an anti-static wrist strap.
