What these words actually mean

Gear and systems that stop you hitting the ground — harness, lanyard, anchor point, guardrails, safety nets. In construction the federal trigger is six feet; in general industry it is four.

Connecting your harness to an anchor point. If there is nothing to tie off to, that is the employer’s problem to solve, not yours to work around.

A self-retracting lifeline. It pays out as you move and locks if you fall, like a seatbelt.

A tank, vessel, boiler, pit, manhole, silo, or trench — anywhere big enough to enter, hard to get out of, and not built for someone to work in. Most confined space deaths are the people who go in after the first person.

A confined space with an added hazard — bad air, something that can bury or crush you, an inward-sloping floor. Entry requires a written permit, an attendant outside, air testing, and a rescue plan.

The person who stays outside a confined space the entire time, watching whoever is inside. They never enter to rescue — that is how the second death happens.

Shutting off a machine’s power and locking it so nobody can turn it on while you are working inside or on it. Your lock, your key. Nobody else removes it.

Welding, cutting, grinding — anything that makes sparks or flame. Usually needs a permit and a fire watch, especially near flammables.

A person who watches for sparks and smoldering during and after hot work — usually at least thirty minutes after the work stops.

Digging. A trench five feet or deeper generally needs a protective system — sloping, shoring, or a trench box. A cubic yard of soil weighs about as much as a car and cave-ins kill in seconds.

A temporary raised platform. Has to be built and inspected by a competent person, fully planked, and have guardrails when it is ten feet or higher.

Someone who can spot the hazards and has authority to fix them or stop the work. Not just experienced — the authority part is the part that matters.

Heat exhaustion and heat stroke. There is no federal heat standard yet, but employers still have to protect you under the General Duty Clause. Federal rule requires drinking water — it does not say it has to be cold.

Water that is safe to drink. That is all the federal rule requires. Temperature is a site practice, not a federal requirement — though OSHA’s own heat guidance recommends cool water.

Fine dust from cutting or grinding concrete, brick, or stone. It scars your lungs permanently. Control it with water or vacuum, not just a paper mask.

Respirators and the program around them. A real respirator requires a fit test, medical evaluation, and training — all paid by the employer. A paper dust mask is not a respirator.

Hard hat, gloves, glasses, boots, hearing protection. With few exceptions the employer pays for it. If you are being told to buy your own, that is usually wrong.

An electrical explosion. The heat can exceed the surface of the sun for an instant. FR clothing is what keeps it from becoming a burn injury.

A forklift, pallet jack, order picker, or reach truck. Your employer has to train you and physically watch you operate. Certification does not transfer between employers, and it is per machine type.

Infectious material in blood — HIV, hepatitis B and C. Employers must have an exposure control plan and provide post-exposure medical evaluation at no cost.

Getting stuck by a used needle or sharp. Every one has to be documented, and you are entitled to a medical evaluation at no cost. The window for treatment is short.

Moving patients without wrecking your back. Mechanical lifts and enough staff. Some states require a written program; federal law does not yet.

Being hit, grabbed, threatened, or assaulted at work — by a patient, resident, coworker, supervisor, or member of the public. Healthcare workers face roughly five times the rate of other industries.

Your employer punishing you for reporting a hazard, an injury, or a violation. It is rarely a firing. It looks like write-ups, the worst assignments, cut hours, being first in a layoff, or the phone not ringing for the next job.

The part of federal law that makes retaliation illegal. The window to file with OSHA is 30 days from the retaliatory act — short, so documenting the timeline comes first.

The catch-all. When no specific standard covers a hazard, the employer still has to keep the workplace free of recognized hazards that can kill or seriously hurt you.

You can refuse work you reasonably believe puts you in imminent danger. The belief has to be reasonable, and you should document the refusal, the reason, and who you told — before anything else happens.

On most industrial sites, stopping unsafe work is not just allowed — it is required. See it, say it. Using the site’s own program is a stronger position than refusing on your own.

A short list of rules an employer treats as absolute — energy isolation, confined space, work at height, hot work, line of fire. Breaking one can get you removed from a site the same day.

Something that almost hurt someone. Same event as an injury minus the luck. No federal rule requires reporting one, but once the employer knows, that hazard is a recognized hazard.

The record of work-related injuries and illnesses an employer must keep. Work-related illnesses go on it too — a skin rash, a chemical exposure, a breathing problem. “Reports are only for injuries” is false.

Insurance covering medical care and lost wages from a work injury. Texas is the only state where private employers can opt out — if yours did, you may have other options.

Not being paid what you earned — unpaid hours, missing overtime, being clocked out early, a short check, or not being paid at all.

Being called an independent contractor when you actually work like an employee. It strips overtime, workers comp, and unemployment. Common in construction.

Anything you do that the law shields from punishment — reporting a hazard, filing a complaint, reporting an injury, talking with coworkers about pay or conditions.

The right to know what chemicals you work with. Labels, training, and a Safety Data Sheet for every chemical, available to you.

The document listing what a chemical is, what it does to you, and what to do about an exposure. You are entitled to see it.

Protection from noise damage. Above 85 decibels averaged over eight hours, the employer must provide hearing protection and annual hearing tests. Ringing after a shift is a warning sign.

Too few workers for the load. A recognized hazard for both the worker and the patients. Some states have nurse-to-patient ratio laws; many do not.

Being required to work past your shift. Documented to increase injury risk. Some states restrict it in healthcare; most do not.
