Overview
UPS Safety Preparedness
UPS Safety Preparedness
The purpose of this section is to reinforce the importance of preparedness when handling
or servicing UPS products. UPS products must go through rigorous testing to ensure their
safety, the same as all of HP's computer-related products. UPS products are proven to be
safe under normal and most abnormal conditions. However, failed or stressed components
within the UPS may present safety hazards in the form of:
• Caustic chemicals leaking from batteries damaged during shipping or from
overcharging.
• Batteries exploding when overcharged or overheated.
• Dangerous voltage and current levels backfeeding through the AC input conductors for
short periods after the AC power is turned off.
• Internal flame or smoke momentarily emitting from the UPS.
Safety Information
Safety information you should know to avoid hazards:
• Obtain proper training before servicing any UPS product.
• Remember, unless properly shut down, all UPS outlet receptacles remain live even after
the UPS is unplugged.
• Follow the published service procedures exactly; deviations may stress components.
• Refer to the handbook, Electrical Safety &Lockout/Tagout, for safe work practices.
• Learn how to:
• Avoid back injuries from handling UPS components.
• Shut down the UPS safely and power-fail the UPS — without pulling the power plug.
• Extinguish electrical fires — without using water or other conductive fire retardants.
• Wash acid from eyes or skin.
• Wipe up acid spills.
• Neutralize leaking batteries.
• Discharge and dispose of old batteries at approved recycling centers.
Handling Emergencies
Be prepared before an emergency occurs. Suggested actions during an emergency:
• DO:
• Call for assistance.
• Report emergencies.
