For years the word 'GAMBLE' was associated with construction excavations. By gambling on unknown soil conditions, ground water, adjacent structures, steep banks, etc., the job could move faster with less cost and less backfill.
The National Institute of Occupational Safety & Health (NIOSH), studies electrocutions occurring between 1982 and 1994. The NIOSH researchers analyzed 224 electrocutions that resulted in 244 workplace fatalities. The information they learned provides valuable lessons for everyone that works with or around electricity.
