What does the competent person look for?
According to OSHA, your company competent person must inspect all excavations each day for evidence of a situation that could result in:
• possible cave-ins.
• indications of failure of protective systems.
• hazardous atmospheres.
• other hazardous conditions.
However, if you work in trenches/excavations you should know much of the same information your competent person does. Why a sudden change could mean disaster for you and fellow workers.
What are unsafe conditions?
Some of the things that could cause an immediate change at an excavation site are:
• A bulldozer or excavator coming too close to your trench could cause a surcharge (overloading) and stress cracks at or near the edge of the trench.
• A sudden downpour could fill the trench or cause rain-soaked soil to give way.
• Accidently striking an underground utility line with a tool could present an immediate electrocution or hazardous atmosphere hazard.
These are just a few of the sudden incidents that need immediate attention and decision-making. That’s why the OSHA rules require your company to train you in the recognition and avoidance of unsafe conditions, the regulations applicable to your work environment, and to control or eliminate any hazards or other exposure to illness or injury.
What does OSHA's regulation cover?
OSHA’s excavation rules apply to all open excavations made in the earth’s surface including trenches. The regulation is in the construction standards at §1926.650-.652 and covers:
Scope and application—The rule applies to all open excavations made in the earth’s surface. Excavations are defined to include trenches.
Specific excavation requirements—to include surface hazards, underground utilities, getting in and out of the excavation, traffic hazards, hazardous atmospheres, emergency rescue, inspections, and fall protection.
Requirements for protective systems—The rule says each employee in an excavation must be protected from cave-ins by an adequate protective system designed in accordance with the OSHA regulations for:
• sloping and benching systems, or
• support, shield, and other protective systems.
Exceptions would be when:
• Excavations are made entirely in stable rock; or
• Excavations are less than five feet deep and examination of the ground by a competent person provides no indication of a potential cave-in.
• Excavations are one of the most dangerous places in construction work. Your knowledge of the hazards and a constant vigil could make a life or death difference.
