What are the hazards? All excavations are hazardous because soil can be unstable. If workers are not using protective systems or equipment while working in trenches or excavations that are five feet or greater in depth, they are in danger of being crushed by a cave-in. To manage the hazards: Pre-job planning is vital to […]

Trench Boxes are different from shoring because, instead of shoring up or otherwise supporting the trench face, they are intended primarily to protect workers from cave-ins and similar incidents. The excavated area between the outside of the trench box and the face of the trench should be as small as possible. The space between the […]

Pneumatic Shoring works in a manner similar to hydraulic shoring. The primary difference is that pneumatic shoring uses air pressure in place of hydraulic pressure. A disadvantage to the use of pneumatic shoring is that an air compressor must be on site. For additional information, see OSHA Technical Manual (OTM) VI. Shoring Types. At Ron Meyer […]

In excavation & trenching, hydraulic shoring is a prefabricated strut and/or wale system manufactured of aluminum or steel. Hydraulic shoring provides a critical safety advantage over timber shoring because workers do not have to enter the trench to install or remove hydraulic shoring. Other advantages of most hydraulic systems are that they: All shoring should […]
