Vehicle Impact from Live Traffic
HighWorkers installing bollards and speed bumps in roadways or car parks are exposed to moving vehicles. Despite traffic control, vehicles regularly encroach into work zones. Working positions at ground level reduce worker visibility to drivers and limit worker awareness of approaching vehicles. Speed bump installation requires extended time working in vehicle paths. Reversing vehicles in car parks present particular risk as drivers focus on parking spaces rather than workers on ground.
Consequence: Fatal or severe injuries from vehicle strikes, multiple trauma, crushing injuries, psychological trauma from near-miss incidents.
Underground Service Strikes During Core Drilling
HighCore drilling for bollard installation risks striking underground services including electrical cables, gas pipes, water mains, telecommunications conduits, and stormwater drains. Drill penetration depth typically 150-250mm for bollards creates high service strike risk. Inadequate service location, inaccurate records, and unmarked services contribute to strikes. Drilling through asphalt or concrete may provide false confidence services are deeper, but shallow services are common in older areas.
Consequence: Electrocution from striking live electrical cables, gas explosions from ruptured gas mains, flooding from damaged water services, service disruption affecting communities, prosecution for damage to infrastructure.
Manual Handling of Heavy Materials
MediumBollards typically weigh 30-100kg depending on material and height, requiring two-person lifts but often handled solo. Speed bump sections weigh 15-30kg each with awkward shapes difficult to grip. Tactile tile boxes contain multiple tiles creating repetitive lifting. Work at ground level requires sustained bending, kneeling, and squatting positions causing postural strain. Carrying materials from vehicles to installation points across uneven surfaces increases handling difficulty. Setting bollards into drilled holes requires precision positioning while supporting full weight.
Consequence: Acute back injuries from sudden heavy lifts, shoulder and knee strain from awkward postures, chronic musculoskeletal disorders from repetitive activities, reduced grip strength and hand injuries, dropped loads causing crushing injuries to feet.
Noise Exposure from Core Drilling
MediumCore drilling through concrete or asphalt generates noise levels typically 100-110dB(A) at operator position. Extended drilling operations for multiple bollard installations create sustained noise exposure. Workers near drilling operations experience elevated noise despite distance from drill. Noise reflects off surrounding structures amplifying exposure. Hearing protection is essential but impairs communication and awareness of traffic and other hazards. Engine-powered drills generate additional noise from power units.
Consequence: Noise-induced hearing loss from repeated exposure, tinnitus and permanent hearing damage, reduced awareness of approaching vehicles and equipment, communication difficulties affecting safety coordination, stress and fatigue from prolonged noise exposure.
Silica Dust from Concrete Drilling
MediumCore drilling and grinding concrete or asphalt surfaces generates respirable crystalline silica dust. Dry drilling creates visible dust clouds exposing workers and public. Silica particles remain airborne for extended periods and can travel significant distances from drilling location. Prolonged silica exposure causes silicosis, an irreversible and potentially fatal lung disease. Despite awareness, many installations proceed without adequate dust suppression, particularly quick jobs where setup of water systems seen as delaying work.
Consequence: Silicosis developing over years of exposure, increased lung cancer risk, chronic obstructive pulmonary disease, reduced respiratory function, breathlessness affecting work capacity and quality of life, no cure once disease established.
