Electricity is energy we depend on for our lives and for work.  When electrical systems are installed and maintained properly, they are controlled effectively.

Therefore, the non-electrical worker has the largest exposure to electrical hazards.  OSHA requires that employers provide training to both electrical workers and non-electrical workers who can be exposed to electrical hazards. According to NIOSH, around 500 worker deaths annually make electrocution the fifth leading cause of workplace fatality (7% of all workplace fatalities).


Cable Change

Cabling is an expensive business and must be treated carefully. The expenditure of substitution once the routes are all concealed is bigger. The fault is not always visible like crushing, bending or kinking. Make sure that your cabling installer have made provision to protect installed cabling from other worker’s actions. This is substantially less costly than changing cabling in the future. If cable routes are guarded with no way of opening them between termination and installation, it is ideal to terminate the cables for the time being, so they can be tested before the routes are protected.


Electrical Testing

Failure of electrical or electronic components usually involves electrical malfunction or operation outside of the desired electrical limits. Therefore, failure analysis typically requires performing electrical tests to duplicate or reproduce the incorrect operation of the component.

Electrical tests are performed at the beginning of the analysis to duplicate the customer’s observed failure mode. Electrical tests are used during the analysis to operate the component for failure site localization and failure mechanism identification (for example, electrical tests can be used to stimulate the component for SEM voltage contrast analysis). Electrical tests are also used to evaluate the effects of analysis techniques intended to modify or eliminate the failure mechanism or physical defect (for example, electrical tests can be used to determine whether a metal-metal short has been removed by a laser or focused ion beam cut).
