What safety precautions should I follow when handling the motherboard?

You should wear an electrostatic discharge (ESD) wrist strap when handling the motherboard; if unavailable, discharge static electricity by touching another metal object first. Always turn off the power supply and unplug the power cord before installing or removing any component, and store the motherboard in an electrostatic shielding container when not installed. Do not operate the motherboard in environments above 60°C (140°F). (Page 2)
