Safety At Work

TL;DR The most common types of drug tests used in the workplace analyze urine, hair, oral fluid, blood, or breath to detect controlled substances or their metabolites. Urine remains the most widely used method and the only specimen currently approved for US federally mandated testing. The standard 5-panel test screens for amphetamines, cocaine, marijuana (THC), … Read more

TL;DR Local Exhaust Ventilation (LEV) is an engineering control system that captures airborne contaminants — dust, fumes, mists, vapours, and gases — at or near their point of generation before they spread into the workplace and reach workers’ breathing zones. An LEV system draws contaminated air through a hood into ductwork, cleans or filters it, … Read more

TL;DR Water hygiene in the workplace is the management of all building water systems to achieve two employer obligations: providing safe potable drinking water for every worker and controlling waterborne pathogens — primarily Legionella pneumophila — within stored and distributed water. Compliance requires a written risk assessment, temperature controls (hot water stored at ≥60°C, delivered … Read more

TL;DR Workplace transport safety is the systematic management of risks created by any vehicle or mobile equipment operating within a work setting — forklifts, HGVs, vans, earth-moving plant, and automated guided vehicles. It rests on three pillars: designing a safe site with segregated pedestrian and vehicle routes, maintaining vehicles that are suitable and properly equipped, … Read more

TL;DR A cable avoidance tool (CAT) is a handheld electromagnetic receiver that detects signals from buried cables and metallic pipes, while the Genny (signal generator) applies a traceable signal to underground utilities so the CAT can locate them. Together they form the industry-standard system for identifying underground services before excavation, as outlined in HSE guidance … Read more

TL;DR — The Numbers That Define This Hazard Formwork safety controls the catastrophic hazards of temporary concrete-mould and support structures during erection, placement, and stripping. Collapse, falls from height, struck-by falling objects, and crush injuries dominate the fatality record. Competent engineered design, jurisdictionally compliant inspection at three distinct phases, and disciplined reshoring prevent most of … Read more

TL;DR — Three Questions That Frame This Discipline What is occupational hygiene? The science and practice of anticipating, recognizing, evaluating, controlling, and confirming workplace hazards that cause disease or impaired wellbeing — focused on the work environment, not the worker’s medical status. Why does it matter? Work-related diseases kill approximately 1.9 million people globally each … Read more

TL;DR — Key Numbers Falsework safety is the temporary load-bearing structure supporting freshly placed concrete, precast units, or steelwork until the permanent structure can carry itself. It demands a written design, an independent check, staged inspection against that design, and written authorisation at each handoff — load, use, and dismantling. Most documented collapses happen during … Read more

TL;DR: I was auditing a mid-sized petrochemical facility in the Gulf when I asked the plant manager a straightforward question: “Show me your management system.” He pointed at three separate binders on three different shelves — one for safety, one for health, and one for environment. Each had a different revision date. The safety binder … Read more

Two specialty chemicals establishments sit four miles apart on the coastal corridor where I run process-safety assurance. One holds around 280 tonnes of a flammable liquid plus two named toxic intermediates above their lower thresholds; the other holds nearly double that inventory, including an acutely toxic intermediate that tips it above the upper threshold. On … Read more
