Starvard University · Workplace Safety 101
You will spot the hazards that injure workers every day and know how to protect yourself and your crew. This course follows OSHA guidance only: the Focus Four hazards, your right to report without retaliation, and the habits that bring everyone home.
Hello, my name is Finn, and I'm going to help you understand this course.
Here it is, explained like you are 10:
Work can hurt you if a ladder is broken, a cord is frayed, or a chemical has no label. This course teaches you to spot those dangers before anyone gets hurt. You learn your right to a safe workplace, how protective gear works, and how to tell OSHA when something is wrong. Safe feels much calmer than sorry.
OSHA is the government office that sets and enforces workplace safety rules. Its worker pages say your employer must keep your workplace free from known hazards, train you in a language you understand, and give you the safety equipment your job requires. You may report a hazard or an injury without being punished, and OSHA will keep your name confidential when you file a complaint.
The lessons build in order. You start with why injuries happen and the rights behind you, then walk the big hazards one by one: falls, falling objects, electricity, and chemicals. Later lessons cover protective equipment, heat and noise, safe lifting, and exactly how to report a problem. By the end, safety is not a poster on a wall. It is how you climb, lift, look, and speak every day.
The whole course in brief
What you will be able to do after this course
The ten lessons
Lesson 1
Most workplace injuries are not freak accidents. They happen when a known hazard meets a rushed moment: a ladder set at a bad angle, a guard removed for one quick cut, a spill left for the next person, a new worker afraid to ask a question. OSHA was created because the law requires employers to provide working conditions free of known dangers, and its training materials return again and again to the same lesson. Hazards are usually visible before someone gets hurt.
Fatigue, hurry, and poor housekeeping multiply every other risk. A tired worker misjudges a step. A cluttered floor turns a small stumble into a fall. Tools left where people walk become struck by hazards waiting for a foot or a head. Weather, heat, noise, and bad lighting wear down attention across a shift, which is why injuries often cluster late in the day and late in the week, when care is thinnest and production pressure is highest.
The hopeful truth is that the causes are ordinary, so the fixes are ordinary too. Inspect the ladder before you climb. Put the tool back. Report the frayed cord. Slow down for the one minute a safe method takes. This course teaches you to see the pattern behind injuries, name the hazard in plain words, and use the rights and reporting routes OSHA gives every worker. Safety is not luck. It is a set of habits, practiced before anything goes wrong.
Lesson 2
Federal law gives you the right to a safe workplace. OSHA states it plainly: your employer must keep your workplace free from known safety and health hazards, and you can speak up or report safety concerns without being punished or treated unfairly. That right belongs to you whether you have worked a site for ten years or ten minutes, and it does not depend on asking permission from the person who created the hazard.
OSHA lists what the right includes. You have the right to receive safety and health training in a language you understand, to work on machines that are safe, and to receive required safety equipment, such as gloves or a harness and lifeline for falls. You have the right to be protected from toxic chemicals, to request an OSHA inspection and speak to the inspector, to report an injury or illness and get copies of your medical records, to review records of work related injuries and illnesses, and to see results of tests taken to find workplace hazards.
Workers can report hazards and injuries without retaliation, and here is how: you can file a confidential complaint with OSHA and ask them to inspect your workplace, online, by phone at 1-800-321-OSHA (6742), or through your nearest OSHA office, and OSHA will keep your identity confidential. If you can, tell your employer about the problem first, because they may fix it quickly. If an employer fires, demotes, transfers, or otherwise retaliates against you for complaining, you can file a whistleblower complaint within 30 days of the retaliation.
Lesson 3
Falls are the leading killer in construction, and they sit at the top of OSHA's Focus Four hazards for a reason. Where workers are exposed to vertical drops of 6 feet or more, OSHA requires fall protection before work begins, in one of three ways: guardrails around the hazard area, safety nets, or personal fall arrest systems for each employee. Unprotected edges, floor holes, and wall openings are the places to guard first, and a harness only helps when it is anchored and worn correctly.
Ladders deserve respect, because the Finn question for this course asks what to do about an unsafe one. Inspect before you climb: broken or missing rungs, split rails, loose fastenings, and oil or grease on steps all mean the ladder comes out of service. Set a leaning ladder on a stable, level surface at an angle where the horizontal distance from the top support to the foot is about one quarter of the ladder's working length, keep the area at the top and bottom clear, and face the ladder as you climb. If a ladder used for access reaches an upper landing, its side rails should extend at least 3 feet above that landing.
Scaffolds add their own rules: they must be sound, set on firm ground, fully planked where you work, and built and moved under competent supervision, never loaded beyond their capacity. If you see an unsafe ladder at work, do not use it and do not quietly pass it to the next person. Tag it or set it aside if your site does that, tell your supervisor, and if nothing changes, use the OSHA complaint route from Lesson 2. A reported ladder is an annoyance. An unreported one can be a funeral.
Lesson 4
Struck by injuries happen when something moves and a worker is in its path: a tool dropped from a scaffold, material swinging from a crane, debris thrown by a power tool, or a vehicle backing through a work zone. OSHA counts struck by incidents among its Focus Four hazards, the four causes behind most construction deaths. Hard hats, eye protection, high visibility clothing, tool tethers, barricaded drop zones, and spotters for moving equipment all exist because gravity and momentum never take a break.
Caught in and caught between injuries are crushing injuries. A worker is pinned between equipment and a wall, pulled into unguarded moving parts, or buried when a trench or excavation collapses. Machine guards that were removed for convenience, loose clothing near rotating parts, and unsupported trenches are the classic setups. Locking out a machine before clearing a jam, keeping guards in place, and staying out of the swing radius of equipment are the habits that prevent them.
Your part is awareness with a voice. Know where loads travel overhead and never walk under a suspended load. Make eye contact with equipment operators before crossing their path. If a guard is missing or a trench wall looks ready to slide, stop, move clear, and report it before anyone else wanders in. These hazards kill quickly, which is exactly why they reward the worker who pauses, looks up, looks around, and speaks before the work resumes.
Lesson 5
Electricity is the fourth of OSHA's Focus Four hazards, and it injures in several ways at once: shock, electrocution, burns, and the falls that follow a shock at height. The danger is invisible, which is why electrical safety runs on habits rather than eyesight. Treat every conductor as energized until it is proven otherwise, and remember that contact with overhead power lines is a recurring killer when ladders, scaffolds, and equipment reach upward without a spotter checking clearance.
Grounding, insulation, and intact cords are the daily defenses. A cord with cut insulation, a missing ground prong, or a tool used in wet conditions with no protection is a report, not a shrug. Ground fault protection is designed to shut power off fast when current leaks where it should not go. Keep electrical panels clear and accessible, keep metal ladders away from conductors, and never use equipment that sparks, smokes, or shocks, however mildly, until it has been checked.
Lockout and tagout protect the person who repairs the machine. Before maintenance, energy is shut off, locked, and tagged so no one can restart the equipment by mistake, and stored energy is released. Only the worker who placed a lock should remove it. If your job does not include lockout duties, your duty is simpler and just as important: never remove another person's lock, never bypass a tag, and report damaged electrical equipment the moment you see it.
Lesson 6
Chemicals injure quietly: a splash in the eyes, fumes in a closed room, a skin rash that grows across a season. OSHA's hazard communication standard exists so that no one has to guess what a product can do. Employers must have a safety data sheet for each hazardous chemical in the workplace, workers must be able to reach those sheets during their shift, and labels must carry a signal word, pictograms, and hazard and precautionary statements that warn you at a glance.
A safety data sheet follows a fixed 16 section format, and knowing the map saves time in an emergency. Section 1 identifies the product and maker. Section 2 gives the hazards. Section 4 lists first aid measures, the section you want when someone is already hurt. Section 5 covers fire fighting, Section 7 handling and storage, Section 8 the exposure controls and personal protection the chemical requires, and Section 11 the toxicological information about health effects. The later sections cover disposal, transport, and regulatory information.
Make the sheet a habit, not a filing cabinet ornament. Before you use a new product, find its sheet, read the hazards and the protection required, and check that the container is labeled, because an unlabeled spray bottle is an accident with the date missing. Store chemicals as the sheet directs, away from products they react with, and never mix cleaners on a hunch. If a sheet is missing for a chemical in your area, ask for it. Access to that information is part of your OSHA rights.
Lesson 7
Personal protective equipment, or PPE, is the gear worn to protect a worker: gloves, eye and face protection, hard hats, hearing protection, respirators, high visibility clothing, and fall harnesses, among others. OSHA requires employers to assess the workplace, choose the right equipment for each hazard, train workers in its use and limits, and make sure it fits and is maintained. Equipment that sits in a locker, fits badly, or is worn wrong protects no one, so speak up when your gear is damaged or the wrong size.
Here is the order that matters: PPE is the last line of defense after other controls. Employers should first try to remove the hazard, substitute something safer, engineer it away with guards and ventilation, and organize work to reduce exposure. Only the risk that remains after those controls belongs to PPE. If a workplace hands you earplugs instead of fixing a deafening machine guard, or a dust mask instead of ventilation, the controls above PPE have been skipped, and that is worth reporting.
On cost, OSHA is direct: protective equipment used to comply with its standards must be provided by the employer at no cost to employees, with narrow exceptions such as everyday clothing and ordinary weather gear, and non specialty safety toe footwear and prescription safety eyewear that the employer allows to be worn off the job site. The employer also pays for replacement PPE, except when an employee has lost it or intentionally damaged it. You should never have to buy your own safety in order to work.
Lesson 8
Heat illness can kill, and OSHA's message fits in three words: Water. Rest. Shade. Employers should encourage workers to drink water every 15 minutes and take frequent rest breaks in shaded areas to cool down, train workers on the hazards of heat, keep an emergency plan for when a worker shows signs of illness, and allow workers to build a tolerance for working in heat gradually. New workers are at special risk, because a body needs time to acclimatize, and pride makes people hide symptoms until they collapse.
Learn the warning signs in yourself and your crew. Heavy sweating, weakness, nausea, and headache call for rest, shade, and water and a supervisor told at once. Confusion, slurred speech, hot dry skin, or fainting are emergency signs: call for medical help immediately and cool the person while you wait. Cold carries the mirror image risk outdoors in winter: layered dry clothing, warm breaks, and watching each other for numb, pale skin and clumsy hands keep frostbite and hypothermia from sneaking in.
Noise harms slowly and permanently. If you must shout to be heard by someone close by, the level is worth raising with your supervisor, and hearing protection provided for the job should be worn for the whole exposure, not the loudest minute. Hearing lost to noise does not come back. The pattern of this lesson is the pattern of the course: know the signs early, use water, rest, shade, clothing, and protection as directed, and treat a coworker's symptoms as your business.
Lesson 9
Back injuries and strains are among the most common reasons workers miss time, and most of them build up from ordinary moments: lifting a box with a twist, carrying a load you cannot see over, reaching overhead a hundred times a shift. Good lifting technique is simple to say and worth practicing. Get close to the load, set your feet, bend your knees, keep the load near your body and your back in its natural curve, and never twist while you lift. If the load is too heavy or awkward, that is what team lifts and carts are for.
Repetitive strain is the slow version of the same problem. Doing one motion thousands of times, with force, in an awkward posture, or without rest, injures tendons, nerves, and muscles over weeks and months. Early signs include aching, tingling, numbness, and weakness that eases on days off and returns at work. Report those signs early. Small changes, such as adjusting a work height, rotating tasks, adding a handle, or slowing a line, work best before the injury becomes permanent.
Mechanical help beats heroic effort every time. Use dollies, hoists, lift tables, and conveyors when they exist, and ask for them when a job regularly demands lifts beyond a comfortable load. Break heavy loads into smaller ones, store heavy items between knee and shoulder height, and keep floors clear so a carried load never meets a tripping hazard. Your back is the only one you get. Spend the minute, use the tool, and ask for the second pair of hands.
Lesson 10
Reporting is where every lesson in this course becomes real. A hazard that is reported can be fixed once. A hazard that is only complained about at lunch waits for its victim. Start with your supervisor when you can, be specific about the place, the condition, and who is exposed, and put it in writing when the hazard is serious or when a verbal report goes nowhere. Photographs, dates, and names turn a vague worry into a record an employer, or an inspector, can act on.
Report injuries and near misses too, not just hazards. An injury report protects your medical care and your workers compensation claim, and it puts the event into the employer's injury and illness records, which OSHA gives you the right to review. A near miss, the falling tool that hit no one, the ladder that slipped with nobody on it, is free information about the next accident. Workplaces that punish near miss reports blind themselves, so a good report, made promptly, is a contribution to the whole crew.
Workers can report hazards and injuries without retaliation, and if your employer will not act, OSHA will: file a confidential complaint online, by phone at 1-800-321-OSHA (6742), or with your nearest OSHA office, and ask for an inspection. OSHA keeps complainants' identities confidential, and a representative may file on your behalf. If you are fired, demoted, transferred, or otherwise retaliated against for using these rights, file a whistleblower complaint within 30 days of the retaliation. Your voice, used early and in writing, is the strongest safety device on any site.
