TL;DR 7 deaths, 58 injuries when the temporary roof structure over the Indiana State Fair grandstand stage collapsed in a single wind gust (Thornton Tomasetti, 2011). Failure began at ~33 mph gusts against an industry-standard capacity near 68 mph —…
TL;DR Estimate before you buy hardware. For most workplaces, manufacturer and HSE magnitude values are enough to start a vibration risk assessment. Measurement and monitoring are not the same thing. Measurement quantifies tool magnitude in m/s²; monitoring tracks how long…
TL;DR Myth: Anti-vibration gloves are a first line of defence against HAVS. Reality: The HSE states no PPE can be shown to reduce hand-arm vibration risk. Myth: A certified glove protects against your tool. Reality: ISO 10819 is a laboratory…
TL;DR — The Numbers That Govern the Assessment HAV action and limit values: 2.5 and 5.0 m/s² A(8). Above the exposure action value you must act; the exposure limit value is a hard legal ceiling (Control of Vibration at Work…
TL;DR — The Numbers That Frame This Risk Cattle cause almost every death. 78 livestock-related fatalities were recorded in Great Britain between 2010 and 2023, and 97% were caused by domestic cattle (Public Health, Conway et al., 2025). It targets…
TL;DR — The Numbers That Define Farm Risk 18.6 deaths per 100,000 full-time workers (US, 2022) — agriculture, forestry and fishing run roughly five times the all-industry rate of 3.7 (NIOSH/BLS, 2024). 23 worker deaths in Great Britain (2024/25) —…
TL;DR — The Numbers That Define This Hazard ~385,000 hospital sharps injuries a year in the US alone, and that figure excludes the unreported ones (US CDC/NIOSH, page updated 2024). HIV ~0.3%, HCV ~1.8%, HBV up to ~30% transmission risk…
TL;DR Myth: Cold injury only happens below freezing. Reality: Hypothermia, trench foot and chilblains all develop above 0°C in wet, windy conditions. Myth: A warming drink helps. Reality: Alcohol speeds heat loss and suppresses shivering; caffeine and nicotine cut blood…
TL;DR — The Numbers That Should Drive Your Heat Program 48 US workers died from environmental heat in 2024 — and most heat deaths strike in a worker's first days, before the body adapts (US Bureau of Labor Statistics via…
TL;DR Hand-arm thresholds: The action value is 2.5 m/s² A(8) (100 points) and the limit value is 5 m/s² A(8) (400 points) (UK HSE, 2025). Whole-body thresholds: The action value is 0.5 m/s² A(8) and the limit value 1.15 m/s²…
TL;DR If you employ outdoor workers in winter, you owe them a legal duty — even though neither OSHA nor HSE sets a cold-temperature limit for outdoor work. If there is no numeric threshold, the burden shifts to your risk…
TL;DR — The Stop-Work Decision in Four Rules If you hear thunder or see lightning, stop outdoor work now. Any audible thunder means lightning is already within strike range — there is no "still far off" margin. If thunder follows…
