Learn how to identify risks, follow safety procedures, and maintain a safe and compliant work environment.
TL;DR Weil’s disease is the severe form of leptospirosis, a bacterial infection spread mainly through the urine of infected rats and contaminated fresh water. Water and sewage workers are exposed when Leptospira enter cuts, grazes, or the eyes, nose and mouth. Early flu-like symptoms can progress to organ failure without prompt antibiotic treatment. A flu-like … Read more
TL;DR Switchgear racking is the controlled insertion (racking in) or withdrawal (racking out) of a draw-out circuit breaker between its connected, test, and disconnected positions. Because the moving primary contacts engage live busbars, racking carries a high arc flash risk. The safest approach is to rack the breaker de-energized, or remotely from outside the arc … Read more
TL;DR — Transformer Safety by the Numbers Transformer safety means controlling three overlapping hazards: high-energy electrical (shock and arc flash), fire and explosion from insulating oil, and chemical or environmental release. The core rule is to de-energize, lock out, and verify zero energy before any work — performing only justified energized tasks under a permit … Read more
TL;DR — The Numbers That Define the Hazard Nanoparticle exposure occurs when particles between 1 and 100 nanometres enter the body — chiefly by inhalation into the deep lung, and secondarily through skin and ingestion. Their small size and large surface area drive oxidative stress, inflammation, and movement to distant organs, producing health effects the … Read more
TL;DR Hazardous waste storage under RCRA is time-limited on-site accumulation, not indefinite holding. Large quantity generators may accumulate for 90 days, small quantity generators for 180 (or 270 when shipping over 200 miles), and very small quantity generators face no federal clock but a 1,000-kilogram cap. Container and containment standards apply throughout. A sealed drum … Read more
TL;DR The waste duty of care is a legal obligation under Section 34 of the Environmental Protection Act 1990. It makes an employer responsible for controlled waste from the moment it is produced until final recovery or disposal, requiring safe storage, accurate description, transfer only to authorised carriers, and records kept for at least two … Read more
TL;DR Waste transfer notes and consignment notes are the legal documents that track controlled waste from producer to final destination in the UK. A waste transfer note covers non-hazardous waste; a hazardous waste consignment note — a special waste consignment note in Scotland — covers hazardous waste. Both must be completed before the waste moves, … Read more
TL;DR Hazardous waste transportation in the United States is regulated jointly by the EPA under the Resource Conservation and Recovery Act (40 CFR Part 263) and the US DOT under the Hazardous Materials Regulations (49 CFR Parts 171–180). The waste must be classified, packed in authorized UN packaging, labeled, and tracked on a manifest from … Read more
TL;DR Chainsaw safety rests on three things working together: correctly certified PPE, proven operator competence, and disciplined cutting technique. Each covers a different way the tool causes harm. Remove any one — skip the chaps, hand a saw to an untrained user, or let the bar drift above the shoulder — and the other two … Read more
TL;DR Wood preservative chemical safety centers on three heavy-duty pesticide systems — chromated copper arsenate, creosote, and pentachlorophenol — that carry known or probable carcinogens. Protecting people means controlling skin and inhalation exposure through substitution, enclosed treatment, dust control, respiratory protection, and health surveillance, then disposing of treated wood without burning or leaching it. A … Read more
