Trenching and excavation hazards resulted
in at least 542 construction fatalities between 1992 and 2001, or 54
deaths annually. Soil stability, soil type, changes in weather, and unshored
trench walls all can contribute to trench cave-ins. Hazards associated
with trench work and excavation are recognized and preventable, yet injuries
and fatalities associated with these hazards continue to occur. Regulations
and consensus standards describe engineering controls, protective equipment,
and safe work practices to minimize hazards for workers during trench
work and excavations.

Preventing Injuries When Working with Hydraulic Excavators and Backhoe Loaders
DHHS (NIOSH) Publication No. 2004-107
Workers who operate or work near hydraulic excavators and backhoe loaders are at risk of being struck by the machine or its components or by excavator buckets that detach from the excavator stick. NIOSH recommends that injuries and deaths be prevented through training, proper installation and maintenance, work practices, and personal protective equipment.

The NIOSH Fatality
Assessment and Control Evaluation (FACE) program is designed to
identify and study fatal occupational injuries. The goal of the FACE
program is to prevent occupational fatalities across the nation by
identifying and investigating work situations at high risk for injury
and then formulating prevention strategies to those who can intervene
in the workplace.
