What safety factors should be considered when bidding on an excavation job? Before preparing a bid, employers should know as much as possible about the jobsite and the materials they will need to have on hand to perform the work safely and in compliance with OSHA standards. A safety checklist may prove helpful when employers […]
Excavation & Trenching Safety
Read posts about Excavation & Trenching Safety from Ron Meyer & Associates Excavating, West Michigan excavation contractors.
How can employers protect workers from hazardous atmospheres inside excavations? Atmospheric testing is required before workers enter an excavation greater than 4 feet (1.22 meters) in depth where an oxygen deficiency or a hazardous atmosphere is present or could reasonably be expected, such as in excavations in landfill areas or excavations in areas where hazardous […]
The Excavation standards require employers to provide support systems, such as shoring, bracing, or underpinning, when necessary to ensure that adjacent structures (including adjoining buildings, walls, sidewalks and pavements) remain stable for the protection of workers. The standards also prohibit excavation below the base or footing of any foundation or retaining wall that could be […]
In addition to cave-ins and related hazards, workers involved in excavation work are exposed to hazards involving falling loads and mobile equipment. To protect workers from these hazards, OSHA requires employers to take certain precautions. For example, employers must: Protect workers from excavated or other materials or equipment that could pose a hazard by falling […]
The Excavation standards require employers to take certain steps to protect workers when installing and removing support systems. For example: Members of support systems must be securely connected to prevent sliding, falling, kickouts or predictable failure. Support systems must be installed and removed in a manner that protects workers from cave-ins and structural collapses and […]
Cave-ins are perhaps the most feared trenching hazard. But other potentially fatal hazards exist, including asphyxiation due to lack of oxygen in a confined space, inhalation of toxic fumes, drowning, etc. Electrocution or explosions can occur when workers contact underground utilities. OSHA requires that workers in trenches and excavations be protected, and that safety and […]
