Cable Avoidance Tool (CAT & Genny): How to Use It Safely

Construction worker in safety vest uses a utility locator to mark underground utilities on a job site, with heavy equipment and team members visible in the background.

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

Formwork Safety: Hazards and Best Practices for Concrete Pours

Construction workers in safety gear inspect and work on a concrete floor slab at a multi-story building site with metal support structures and reinforcing bars visible.

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

What Is Occupational Hygiene? Principles, Methods & OEL Guide

Three workers in safety gear conduct equipment inspection in an industrial warehouse, with one operating a grinder while others document measurements and take readings.

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

Falsework Safety: Design, Inspection and Collapse Risks

Construction workers in safety vests and hard hats operate concrete pumping equipment on a multi-level building foundation with steel scaffolding and formwork.

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

What’s SHEMS? Meaning, Key Elements & Standards Explained

A woman in a blue lanyard presents a PDCA Cycle diagram to four workers in tan and yellow safety gear seated around a table during a morning management review meeting in a high-rise office.

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

Upper Tier vs Lower Tier COMAH Sites: Key Differences

Industrial refinery facility with workers in safety gear inspecting equipment, large storage tanks, pipelines, and a tanker truck during operations at a coastal site.

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

COMAH Safety Report: What It Must Contain

Two industrial workers in safety gear review blueprints on an elevated platform at a petrochemical refinery, overlooking storage tanks, pipelines, and processing equipment.

TL;DR Regulation 8 of the Control of Major Accident Hazards Regulations 2015 does not offer a polite suggestion. It states that the operator of an upper-tier establishment must prepare a safety report and must not construct, operate, or significantly modify that establishment until the Competent Authority has communicated its conclusions on it. Two winters ago … Read more

10 Night Shift Safety Tips Every Worker Should Follow

Two workers in high-visibility safety gear discuss operations at a nighttime port facility with stacked shipping containers, a cargo handler, and industrial cranes illuminated by floodlights.

The study wasn’t about drunk drivers. It was about night-shift workers heading home after a normal shift — no alcohol, no drugs, no medications. After a night of sleep, the near-crash rate across their test drives was zero. After a night shift, 37.5% of those drives produced a near-crash event, and every single one of … Read more

Lone Working on Night Shifts: Risks and Safety Tips

A man in a dark polo shirt stands at a pharmacy counter reviewing paperwork, with a barcode scanner in hand, shelves of medication boxes visible behind him and a display showing "TIME DELAY ACTIVE.

TL;DR Lone working on night shifts is a compound hazard: fatigue lowers hazard detection, isolation delays rescue, and low-witness conditions amplify violence exposure. Safe operation requires a specific risk assessment, scheduled check-ins, engineered controls such as lighting and CCTV, administrative limits on shift length, and a dedicated lone-worker device as the last line of defence. … Read more

Safe Isolation Procedure: Step-by-Step Guide (10 Steps)

Electrician wearing safety gear working on electrical panel with circuit breakers and wiring in an industrial facility.

TL;DR Safe isolation is the controlled process of disconnecting electrical equipment from every source of supply, physically securing that disconnection with a lock and tag, and verifying the circuit is dead using GS38-compliant test equipment at the point of work — a legal duty under the Electricity at Work Regulations 1989 and equivalent standards internationally. … Read more
