all weathers; inside in dusty industrial plants and mills; to state-of-the-art clean-rooms in hospitals and, r. d; N% o2 T$ |
manufacturing plants. The work often requires considerable standing, bending, crawling, lifting,4 j: E8 k% _* `2 q2 U2 ]

scaffolding at great heights. Hazards include electric shocks, burns, and falling objects.- B( M( p5 W* r! |9 L0 m
Construction electricians are required to have good mechanical ability, a thorough

the use of hand and power tools and test equipment.
