TL;DR What is the Bradley Curve? A descriptive management model that maps safety-culture maturity against injury rate, claiming incidents fall as culture matures. What are the four stages? Reactive, Dependent, Independent, and Interdependent — moving from "accidents just happen" to…
TL;DR 50 µg/m³ — OSHA's 8-hour exposure limit for respirable crystalline silica in general industry, with action required at 25 µg/m³ (US OSHA, 2016). 100 µg/m³ — the UK and EU 8-hour limit for the same dust, double the US…
TL;DR Engineering controls beat PPE. Guarding, interlocks, and local exhaust ventilation outrank respirators and gloves on every plastics hazard. Fix the higher-order control first. Machine guarding is the killer. Clamp and feed-mechanism amputations dominate the injury record, and OSHA's renewed…
TL;DR Guard the whole driveline, not just the straight shaft. PTO safety guards must cover the stub, the universal joints, and the implement coupling — the joints are where most snags actually begin. A guard that spins with the shaft…
TL;DR What is a safety culture maturity model? A staged framework that locates where an organisation's safety culture sits today and maps a route toward shared ownership of safety. What are the stages? Most models use five — pathological, reactive,…
TL;DR Confirm reportability first: Only six specific trigger categories require a RIDDOR submission. Non-worker hospitalisation, specified injuries, and over-7-day absences are the most commonly missed. Identify the right person to file: The "responsible person" is rarely the injured worker or…
TL;DR — How to Measure Safety Culture Measure climate directly, infer culture over time — you survey perceptions at a point; culture is read from patterns across many methods. Triangulate four data streams — perception surveys, interviews and focus groups,…
TL;DR — Myth vs Reality Myth: Concrete is always safer because it's stronger. Reality: a rigid concrete Jersey barrier contains a vehicle well but transfers more force into the occupants. "Stronger" and "safer for the people inside" are different axes.…
TL;DR If you hire equipment, then your safety duty does not transfer with it. The hiring business stays the duty holder for safe use under PUWER (GB). If equipment arrives faulty, then you must not put it into use. Reject…
TL;DR Separate the file — Keep medical and health information in a confidential file apart from the personnel file (ADA, US; security principle under UK GDPR, UK). Collect only what you need — Limit collection to information that is job-related…
TL;DR — Four Myths That Get People Killed Myth: Crowd deaths are caused by panic and trampling. Reality: most are compressive asphyxia in a dense, near-static crowd — people die upright. Myth: A venue's licensed maximum is a safe number.…
TL;DR — Myth vs Reality Myth: People die in crushes because they panic and run. Reality: most deaths are from compressive asphyxia in crowds so dense that victims cannot move at all. Myth: A "stampede" is the danger. Reality: genuine…
