Hazards are anything that can cause harm, injury, or damage in the workplace. This section covers various types of hazards, including physical, chemical, biological, and ergonomic risks. Learn how to identify hazards, assess risks, and apply control measures. Understanding hazards is the foundation of effective safety management and accident prevention.
A packaged watertube boiler rated for 60,000 pounds of steam per hour holds somewhere between 12,000 and 15,000 pounds of water inside its drum and generating tubes — pressurised to roughly 350 psig and heated to 440°F. That water is not liquid the way a bathtub is liquid. It is liquid only because the pressure … Read more
I was standing seventy metres from a 16-inch carbon steel spool piece during a pipeline hydrotest on a gas processing facility in the Gulf when the bolted flange connection failed at 1.3 times design pressure. The blind flange launched sideways like a disc, struck a cable tray support, and embedded itself into a concrete firewall. … Read more
Toluene has a flash point of 4°C. At room temperature, an open container doesn’t just release vapour — it generates a flammable atmosphere that sits heavier than air, pooling in trenches, pits, and low points across the floor. The vapour is invisible. It carries no colour. At concentrations between 1.1% and 7.1% by volume, a … Read more
TL;DR I was walking through a warehouse in Southeast Asia when I saw a worker drop to one knee mid-lift. He wasn’t carrying anything unusually heavy — a 15-kilogram box of fasteners. But he’d been doing it for three straight hours without rotation, bending and twisting from a pallet on the ground to a shelf … Read more
TL;DR I was conducting a routine walkthrough on a tank farm repaint project at a refinery complex in the Gulf when I found two painters inside a partially enclosed bund wall — spray-applying an epoxy coating with no forced ventilation, no respiratory protection, and no atmospheric monitoring. The vapor concentration was high enough that I … Read more
TL;DR I was reviewing a contractor’s monthly safety report on a refinery turnaround when I noticed something that stopped me mid-page. The report listed zero accidents, zero incidents, and zero near misses for thirty consecutive days. Thirty days of hot work, confined space entries, scaffold erections, heavy crane lifts, and simultaneous operations — and apparently … Read more
I was called to a residential infrastructure project where a 2.4-meter utility trench had collapsed onto a worker twenty minutes before I arrived. The trench had no shoring, no sloping, no benching — just vertical walls cut into wet clay after two days of rain. The crew had been digging and laying pipe in unprotected … Read more
I once walked onto a Tier-1 petrochemical expansion project and stopped a crew of pipefitters working on a pipe rack 12 meters up. They had their harnesses on, but they were clipped to a 2-inch conduit—a “perceived” anchor point that would have snapped like a twig in a fall. This is the reality of work … Read more
As an Industrial Hygienist and Environmental Specialist, I was auditing a mid-sized chemical processing plant in the Middle East when my portable multi-gas detector started alarming near the bulk storage tanks. A localized temperature inversion had trapped low-lying fugitive vapor emissions, creating a toxic micro-environment that the local workforce was completely unaware of. This was … Read more
Loading docks are busy areas where trucks, trailers, pedestrians, lifting devices, and other equipment frequently move. Serious or fatal injuries can result from loading dock hazards, such as unsecured vehicles driving on the dock, lift trucks tipping over or falling, and pedestrian collisions with lift trucks, falling loads, or tractor-trailers. Therefore, it is important to … Read more
