1.1 SAFETY SUGGESTIONS
Regardless of how well electrical equipment is designed, personnel can be exposed to dangerous
electrical shock when protective covers are removed for maintenance or other activities. Therefore, it is
incumbent on the user to see that all safety regulations are consistently observed and that each individual
assigned to the equipment has a clear understanding of the first aid related to electrical shocks. (see next
pages)
In addition these safety practices must be followed:
 Do not attempt to adjust unprotected circuit controls or to dress leads with 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 precautions.
 Remember that some semiconductor cases and solid-state circuits carry high voltages.
 Do not assume that all danger of electrical shock is removed when the power is off. Charged
capacitors can retain dangerous voltages for a long time after power is turned off. These capacitors
should be discharged trough a suitable resistor before any circuit points are touched.
 Don't take chances. Be fully trained. Screen Service Italia equipment should be operated and
maintained by fully qualified personnel.
 Do not service alone and do not perform internal adjustments of this unit unless another person
capable of rendering first aid and resuscitation is present.
 Some components used in the construction of this equipment contain Beryllium Oxide (BeO). This
substance is harmless as it is, but becomes highly dangerous if it is ground to powder. Special
procedures of disposal must be observed in case of failure of these devices.
NOTE: This section is not intended to contain a complete statement of all safety precautions which
should be observed by personnel in using this electronic equipment or others.
Screen Service shall not be responsible for injury or damage resulted from improper procedures or from
using it by improperly trained or inexperienced personnel.
