How To Guide

Portable generators kill about 85 people in the U.S. every year, almost entirely through carbon monoxide - and almost always because the unit ran too close to the home. This guide covers the 20-foot placement rule, the CO alarms that back it up, transfer switches versus deadly backfeeding, and safe refueling start to finish.

Solvent vapor you cannot see and gloves that quietly pass chemicals through to your skin are the two traps of degreasing work. This guide matches glove materials to common shop solvents, explains when an organic vapor respirator is required, and covers the brake cleaner and welding heat combination that produces phosgene gas.

A car battery is a box of sulfuric acid that exhales explosive hydrogen gas, wired to enough current to weld a wrench. This guide covers the disconnect order (negative first, negative last), the jump-start sequence that keeps the spark away from the battery, acid splash PPE, terminal corrosion cleanup, and lead-acid vs lithium handling.

A car that slips off a jack does not injure the person under it - it kills them, and NIOSH fatality investigations repeat the same story every year. This guide covers the support rule (the jack lifts, the stands hold), surfaces and wheel chocks, the shake test, under-car PPE from goggles to bump cap, and a full setup workflow.

Brake dust from older or imported pads can contain asbestos, and no dust from any pad belongs in your lungs - which is why OSHA bans dry brushing and compressed air in brake work. This guide covers wet-wipe methods, the P100 respirator and glove specs, jack stand setup, spring-clip eye hazards, and a start-to-finish pad change.

Snow clearing injures people four ways: snow blower amputations, shoveling heart attacks, struck-by incidents at the roadside, and falls on ice. This guide leads with the clogged-chute rule that saves fingers, covers cardiac pacing for shovelers, and specs the eye, hand, foot, hi-vis, and hearing protection that winter work needs.

Pool chemicals send thousands of people to the emergency room every year, and most injuries trace back to two mistakes: mixing incompatible chlorine products and splashing acid. This guide covers the mixing rules, the exact PPE specs for goggles, gloves, and respirators, a safe dosing workflow, and storage separation that prevents fires.

Every pesticide label is a legally enforceable document under FIFRA, and its PPE section is the minimum the law allows you to wear. This guide decodes signal words, explains why mixing concentrate is the highest-exposure step, covers unlined gloves, respirators, and re-entry intervals, and walks a lawn treatment start to finish.

Tree work kills more workers per capita than almost any other job, and the killers - falling limbs, falls, and power lines - do not care whose yard it is. This guide scopes what a homeowner can trim safely with both feet on the ground, teaches the three-cut method and drop zone control, and says plainly when the job belongs to a pro.

Splitting firewood injures hands, eyes, and feet in predictable ways: glancing maul strikes, steel chips off mushroomed wedges, and fingers caught in log splitters run by two people. This guide covers block setup, maul technique that spares your back, the one-operator splitter rule, and the PPE that belongs on before the first swing.

A pressure washer produces a water jet strong enough to inject debris deep under skin, strip flesh, and knock you off a ladder with recoil. This guide decodes the nozzle color system, explains why a pressure-washer wound is a surgical emergency, covers GFCI and carbon monoxide rules, and lists the exact PPE to wear for every job.

A string trimmer flings grit, wire, and stone chips fast enough to cause permanent eye damage, and gas heads run loud enough to erode hearing over a season. This guide covers the exact PPE to wear, how to prep the area, safe sweeping technique, the 50-foot bystander rule, and the upgrades required before you mount a brush blade.
