Excavation and trenching is statistically the most hazardous work in the U.S. construction industry. Frequent news stories from around the country attest to the danger. More than 100 workers are killed each year in trench cave-ins alone. Countless others are injured or maimed, physically and psychologically.
Recognizing the need for more effective regulations on excavation safety, the Occupational Safety and Health Administration (OSHA) published a revised federal standard in 1990 to establish more clearly the requirements for protecting employees in excavations. The definitive standard greatly increases the flexibility you and your workers have in choosing protective systems.
