Safety and First Aid Suggestions
No matter how well electrical equipment is designed, you can be exposed to dangerous electrical shock when
protective covers are removed for service or other activities. Therefore, you should consistently observe all
safety regulations, be sure that you thoroughly understand the dangers related to electrical hazards, and have
some knowledge of first aid required for electrical injuries. In addition, follow these general safety practices:
Muscular spasm or unconsciousness can prevent a victim from freeing himself from the electrical power. If
someone appears to have received an electrical shock, turn power off before attempting first aid.
Do not touch or adjust unprotected circuit controls or dress
leads with the power on.
Always avoid placing parts of the body in series between
ground and circuit points.
To avoid burns, do not touch heavily loaded or overheated
components without taking precautions.
Remember that some semiconductor cases and solid-state
circuits carry high voltages.
Do not assume there is no danger of electrical shock when
power is off. Charged capacitors can retain high voltages for a
long time after power is turned off. You should discharge
capacitors through a suitable resistor before touching any
circuit points.
Don’t take chances. Be fully trained. Only qualified personnel
should operate and maintain Ampex equipment.
DANGER!
Do not touch electrical shock victims or their clothing
before disconnecting power. You can also become a shock
victim.
