In dry regions, use humidifiers or regularly mop the floor to ensure proper humidity in
the equipment room.
In regions with high humidity, use dehumidifiers.
Use dust-free materials for the floor, walls, and ceilings.
Screen exterior doors and windows. The external windows of the equipment room
should be sealed for anti-dust purposes.
Clean the equipment room and air filters on the devices once every three months.
Wear the ESD uniform, ESD gloves, and ESD shoes before entering the equipment
room.
Locate the equipment room far away from areas with dense corrosive gases, such as
chemical plants.
The air intake vent of the equipment room must not face any pollution source.
Place batteries in a different room from the devices.
Invite professionals to measure the temperature, humidity, and other factors periodically.
Provide operators with ESD protection training.
Adjust the humidity to reduce the impact of static electricity.
Install an ESD floor in the equipment room.
Wear an antistatic suit, ESD gloves, and antistatic shoes before entering the equipment
room.
Use ESD tools, such as ESD wrist straps, ESD tweezers, and extractors.
All the conductors in the equipment room, including computer terminals, must be
properly grounded. Set up an antistatic workbench.
Electrostatic sources, such as non-ESD plastic bags, non-ESD foam, and rubber objects
must be kept at least 30 cm away from ESD-sensitive components and boards.
