OSHA Standards for Trenching & Open Ditches
Construction that involves open ditches and trenching can present numerous hazards to workers. The Occupational Safety and Health Administration (OSHA) has established certain guidelines to promote awareness and safe conditions while doing this type of work.-
Purpose
-
OSHA standards for trenching and open ditches help employers protect employees from cave-ins, digging into buried utility lines and other potential hazards. This also includes the employer taking into account the site conditions, analyzing potential safety concerns and training workers.
Preparation of Site
-
Employers must inform utility companies of trenching operations and have the location of underground pipes and power lines laid out before work begins. Workers must be provided with appropriate safety equipment, such as clothing, that is highly visible if they will be near traffic. A safety plan must also be in place that covers appropriate work procedures and how to deal with unexpected hazards that may come up during the course of work.
Cave-In Prevention
-
These OSHA guidelines outline protection for workers from cave-ins while working in a trench or opened ditch. If an excavation has the potential for cave-ins, a protective system must be established. This can include digging the sides of the trench so that it slopes inward, and installing supports for the sides of the trench. A shield can also be installed that separates the work area from the side of the open trench.
