Workplace safety is essential for protecting employees and ensuring smooth operations. This section covers a wide range of safety topics, including hazards, risk management, and preventive measures. Learn how to identify risks, follow safety procedures, and maintain a safe and compliant work environment.
TL;DR An asbestos management plan is a written, site-specific document that sets out how asbestos-containing materials in a building will be identified, assessed, monitored, and controlled to prevent exposure. It records what ACMs are present, what decisions have been made about each one, who is responsible for ongoing management, and what procedures are in place … Read more
TL;DR An asbestos register is a live compliance document that records the identification, location, type, quantity, condition, and risk assessment of all known and presumed asbestos-containing materials (ACMs) in a building. Under UK law (CAR 2012, Regulation 4), it must be kept current and made available to anyone who may disturb ACMs. In Australia, WHS … Read more
TL;DR UN packaging codes are a standardised marking system printed on containers certified for transporting dangerous goods. Each code identifies the packaging type, construction material, hazard-level rating (Packing Group I, II, or III), weight or pressure capacity, and manufacturing origin. The system is defined by the UN Recommendations on the Transport of Dangerous Goods and … Read more
TL;DR Demolition safety encompasses the planning, hazard controls, and procedures required to protect workers and the public during the intentional dismantling of structures. Before any demolition work begins, OSHA requires an engineering survey by a competent person to assess structural integrity and identify hazards. A written demolition plan, utility isolation, hazardous material abatement, and ongoing … Read more
TL;DR Tunnelling safety hazards include ground collapse, toxic or explosive atmospheres, fire, water ingress, noise, silica dust exposure, and struck-by incidents from underground plant. Control measures follow the hierarchy of controls — from elimination through design-phase decisions, to engineering controls like mechanical ventilation and ground support systems, administrative controls including atmospheric monitoring and emergency planning, … Read more
TL;DR Tunnel boring machine operations present risks across six categories: geological hazards (ground collapse, water inrush), mechanical hazards (cutterhead failures, muck transport injuries), atmospheric hazards (gas exposure, silica dust), hyperbaric intervention risks (decompression sickness during cutterhead maintenance), emergency evacuation challenges in long tunnels, and chronic occupational health effects including noise-induced hearing loss and respiratory disease. … Read more
TL;DR Piling operations present elevated safety risks including struck-by injuries from falling hammers or swinging piles, entanglement in rotating auger parts, rig instability and collapse, underground service strikes, noise and vibration exposure exceeding occupational limits, falls from height on rig leads, and exposure to hazardous substances in contaminated ground. Effective piling safety requires controls at … Read more
TL;DR Different piling methods carry distinct safety risks. Driven piling creates impulse noise hazards and ground vibration, bored piling introduces ground-collapse and contaminated-spoil risks, CFA piling adds auger entanglement and concrete hose-whip dangers, and all methods depend on correctly designed working platforms to prevent rig overturning — the single most recurrent serious piling incident across … Read more
TL;DR Pre-erected steel inspection is the systematic verification of steel materials, fabricated components, and construction site readiness before structural steel erection begins. It covers material receiving checks against mill test reports, fabrication quality verification against design drawings and welding codes such as AWS D1.1, and site-readiness assessment — including foundation cure strength, anchor bolt positioning, … Read more
TL;DR Ground collapse in tunnelling is the loss of excavation stability beyond design tolerance, spanning local roof falls, face instability, wedge failure, seepage-driven chimney collapse, and full daylight breakthrough to the surface. Prevention works only when each mechanism is matched to its specific control — face support pressure, ground improvement, initial lining, monitoring with pre-defined … Read more
