Construction electricians work in the full range of environmental conditions: from outside in# R" H: C- ~7 s$ Z N( A! o
all weathers; inside in dusty industrial plants and mills; to state-of-the-art clean-rooms in hospitals and

scaffolding at great heights. Hazards include electric shocks, burns, and falling objects.( Z4 T$ @6 n" G+ T1 o3 [4 X

the materials and techniques of construction. All construction electricians are required to be competent in

For safety, permits and other regulations they follow local electrical, building and safety codes.
