Combustible gas

Batteries

Do not touch devices with bare hands because the ESD from the human body
■
may damage the electrostatically sensitive elements on a board.
Electronic circuits are prone to damage caused by ESD. When dealing with a
■
disk, especially a raw disk, wear an ESD-preventive wrist strap, ESD-preventive
gloves, and ESD-preventive suit. Touch only the edge of the disk.
Use appropriate ESD-preventive bags when picking up, putting down, and
■
transporting equipment or parts.
To prevent short-circuits, do not leave or drop screws or other metallic parts in the
chassis.
When you install or maintain a device, follow regulations about the use and
placement of tools. You can avoid short-circuits of the devices that are caused by
metallic tools.
See "Combustible gas"
Never place or operate a device in an environment with combustible or explosive
gases, or smoke.
Operations to any electronic devices in the presence of combustible gases cause
an extreme danger.
