Review the critical hazards, potential consequences, persons at risk and recommended control measures for Excavation in one professional HSE workspace.
Review the key hazards, consequences and control measures for Excavation in a structured professional HSE format.
Crushing, suffocation or fatality
Workers inside excavation
Suitable sloping, shoring or protective system and competent-person inspection
Reinspect after rain or ground-condition changes
Electric shock, fire or process release
Excavation crew
Drawings, utility locating, permit and controlled excavation
Use controlled hand digging in uncertain areas
Fracture or serious injury
Pedestrians and workers
Barricades, safe crossings and lighting
Use robust physical protection in high-traffic areas
Collapse, slip or drowning
Workers inside excavation
Water control and pumping
Stop work and reassess stability if water ingress continues
Edge collapse or vehicle falling into excavation
Operators and excavation workers
Vehicle barriers and safe stand-off distance
Mark heavy-vehicle approach limits in the site plan
Poisoning or oxygen deficiency
Workers in deep or enclosed excavations
Gas testing where required
Define atmospheric-testing criteria where process or gas hazards may exist
Excavation wall collapse
Workers inside excavation
Edge-load control and barriers
Keep materials and equipment at a safe setback distance
Loss of ground stability, slips or collapse
Excavation workers
Excavation inspection and drainage
Continuously monitor water accumulation and provide suitable dewatering
Poisoning, oxygen deficiency or loss of consciousness
Personnel working in deep excavations
Risk assessment and gas testing where required
Use continuous or periodic atmospheric monitoring where a hazard may exist
