Workplace Hazards Examples: Six Types and Controls
Examples of every workplace hazard type: physical, safety, chemical, biological, ergonomic, and psychosocial, plus how to find yours and control them.
Workplace Hazards Examples
The six categories with concrete examples in each, what they look like in an office, a shop floor, and a kitchen, the two groups small employers almost always miss, and the control ladder that decides whether a fix survives a busy week
The first hazard list I wrote for my own company had eleven items on it, and every one of them could cut, burn, or fall on somebody. It felt thorough. It was also the wrong list.
What cost us actual days that year was a stack of boxes narrowing a fire route, a laptop set on a shelf at chin height for a month, and one person taking every closing shift because nobody had looked at the schedule as a safety question. None of the three would have made my list, because my instinct only searched for things with edges.
That is what the hazard categories are for. Sorting a workplace into physical, safety, chemical, biological, ergonomic, and psychosocial forces you to look in the places instinct skips. This guide gives concrete examples in each category, what they look like in an office, a shop floor, and a kitchen, and the order of controls that decides whether a fix is still working in three months. At FirstHR I build the onboarding, training records, and employee files that a safety position gets documented in, so the paperwork half of this is the part I work on daily. This is general information rather than legal advice, and standards vary by industry and state, so check the ones that apply to you.
What Counts as a Workplace Hazard
A workplace hazard is any condition, substance, activity, or way of organizing work that has the potential to cause injury or illness to a person at work. Potential is the operative word: nothing has to have happened yet for something to qualify.
Hazard and risk are not synonyms, and mixing them up is the most common reason an assessment turns into a list of adjectives. The hazard is the drum of solvent. The risk is how likely someone is to be harmed by it and how badly, which depends on how often it is opened, by whom, and with what ventilation.
The scale is worth holding in mind, because it explains why the categories most people skip are the expensive ones. Private industry employers reported 2.5 million recordable nonfatal injuries and illnesses in 2024, a rate of 2.3 cases per 100 full-time equivalent workers and the lowest count in a data series going back to 2003, according to the Bureau of Labor Statistics Survey of Occupational Injuries and Illnesses released in January 2026. Almost none of those cases involved a hazard nobody had ever seen before.
Legally, the backstop is broad. Beyond the specific standards that apply to your industry, the general duty clause requires a workplace free from recognized hazards likely to cause death or serious physical harm, which is why a hazard with no standard attached is still your problem.
The Six Hazard Categories
Workplace hazards are conventionally sorted into six categories: physical, safety, chemical, biological, ergonomic, and psychosocial. Some frameworks list five by folding safety hazards into the physical group, which is the same content organized differently rather than a disagreement about what is dangerous.
Keeping safety separate from physical is a practical choice rather than an academic one. The two groups behave differently on a walkthrough: safety hazards announce themselves in a single moment, while physical hazards accumulate quietly and need a measurement or a question rather than a glance.
The categories are also a useful audit of your own attention. If your existing list is entirely safety hazards, you have written down what you are afraid of rather than what is harming people, and the fix takes an afternoon.
Physical Hazard Examples
Physical hazards are forms of energy in the environment that act on the body without any substance being ingested or any contact being made: noise, heat, cold, vibration, radiation, poor lighting, and air pressure. The harm is usually cumulative, which is exactly why they get missed.
| Physical hazard | What it looks like in practice | First control to reach for |
|---|---|---|
| Noise | A room where people raise their voices to be heard at arm’s length: compressors, saws, blenders, kennels, music systems in a bar | Quieter equipment or a barrier before hearing protection, plus exposure monitoring where it is borderline |
| Heat | Kitchens, warehouses without cooling, roofing and landscaping crews, delivery vans in summer | Shade or cooling, scheduled rest and water breaks, and acclimatization for new and returning workers |
| Cold | Walk-in freezers, outdoor winter work, unheated loading docks | Warm-up breaks in a heated space, insulating layers issued rather than assumed, and buddy checks |
| Vibration | Hand tools such as grinders and impact drivers, ride-on machinery, long vehicle shifts | Lower vibration tools, shorter continuous run times, and maintenance that keeps tools balanced |
| Poor lighting | Stairwells, storage mezzanines, plant rooms, evening deliveries at a rear entrance | Fix the fixture rather than issue a flashlight, and check lighting on the routes people use after dark |
| Radiation | Welding arcs, ultraviolet from outdoor work, x-ray and imaging equipment in clinics | Screens and enclosures, tinted protection matched to the process, and distance from the source |
Noise deserves a line of its own because of how quietly it works. The National Institute for Occupational Safety and Health (NIOSH) puts about 27 million workers exposed to hazardous noise each year, and treats noise as hazardous at 85 dBA and above. It also counts roughly 22 million workers exposed to ototoxic chemicals, which damage hearing on their own and worsen the effect of noise, a combination almost nobody checks for.
Safety Hazard Examples
Safety hazards are the conditions that cause sudden traumatic injury: walking surfaces, work at height, unguarded machinery, electricity, vehicles, confined spaces, and blocked egress. They are the most familiar group and still the deadliest.
Federal fatality data makes the ranking concrete. There were 5,070 fatal work injuries in 2024, a rate of 3.3 per 100,000 full-time equivalent workers. Transportation incidents were the most frequent fatal event at 1,937 cases, or 38.2 percent of the total, and fatal falls, slips, and trips accounted for 844 (Census of Fatal Occupational Injuries, 2024).
| Safety hazard | Concrete example | Where it hides in a small business |
|---|---|---|
| Slips, trips, and falls on the level | A cable across a walkway, a wet floor with no sign, a mat with a curled edge, a step nobody expects | Back-of-house corridors, entrances on rainy days, and anywhere a temporary fix became permanent |
| Falls from height | A step ladder used sideways, a mezzanine with a removable rail left off, roof access for an HVAC unit | Stock retrieval and light bulb changes, which are treated as errands rather than as work at height |
| Machinery and moving parts | An unguarded blade, an interlock defeated to clear jams faster, loose clothing near a rotating shaft | Cleaning and unjamming, which happen outside the operating procedure the machine was bought with |
| Electrical | Damaged cords, daisy-chained power strips, a panel with boxes stacked against it, water near outlets | Seasonal decorations, space heaters, and equipment added after the last electrical inspection |
| Vehicles and mobile equipment | Forklift and pedestrian routes crossing, reversing without a spotter, deliveries in a shared yard | The loading area, and any job where driving is incidental to the role rather than the role itself |
| Confined spaces | Tanks, pits, crawl spaces, and large duct runs entered for cleaning or repair | Maintenance contractors doing a task your team never performs and never planned for |
| Fire and egress | An exit blocked by stock, a propped fire door, an extinguisher behind a pallet | The week after a big delivery, when floor space is borrowed from the route out |
Two patterns run through that table. The first is that most of these appear during non-routine work: cleaning, unjamming, restocking, and repairing. The second is that they cluster where space is temporarily borrowed. A structured walkthrough catches both, and our safety inspection checklist gives that walk a fixed route so neither gets skipped on a busy day.
Chemical Hazard Examples
Chemical hazards are substances that harm through contact, inhalation, ingestion, or injection, and every workplace has them, because bleach, degreaser, and toner are chemicals regardless of the industry on the door. Harm ranges from a same-day burn to an illness that appears decades later.
| Chemical hazard | Typical example | The failure that turns it into an incident |
|---|---|---|
| Cleaning products | Bleach, ammonia-based cleaners, drain openers, oven cleaner, sanitizer concentrate | Decanting into an unlabeled bottle, or mixing two products in the same bucket |
| Solvents and fuels | Degreasers, paint thinner, adhesives, gasoline for equipment, propane cylinders | Storage next to an ignition source, or use in a room with no working ventilation |
| Dusts | Wood dust, silica from cutting concrete or stone, flour in a bakery | Dry sweeping, which puts a settled hazard back into the air everyone is breathing |
| Fume and vapor | Welding fume, soldering, spray painting, hot glue and laser cutting | Local extraction that exists but is switched off because it is loud |
| Compressed and cryogenic gases | Carbon dioxide for beverage systems, oxygen and acetylene, nitrogen | Cylinders unsecured, or a leak in a small unventilated room |
| Pesticides and treatments | Rodent bait, insect spray, pool and spa chemicals, landscaping herbicides | Applied by someone with no training because it is sold on an ordinary shelf |
The compliance side is unusually well defined here. Hazard communication is consistently one of the two most frequently cited federal standards, and it reaches any workplace that stores chemicals rather than only the ones that manufacture them. The obligations are a written program, safety data sheets employees can actually reach, labels on every container including the ones you filled yourself, and training that covers what is in the building.
Biological Hazard Examples
Biological hazards are living organisms and the material they leave behind: bloodborne pathogens, respiratory viruses, mold, contaminated food and water, and pests. Healthcare is the obvious case, and it is a long way from the only one.
| Biological hazard | Who meets it in an ordinary business | Control that actually works |
|---|---|---|
| Blood and bodily fluids | Anyone who renders first aid, cleans a bathroom, or handles a sharps injury | Written exposure control plan where exposure is reasonably anticipated, gloves and barriers at hand, vaccination offered where required |
| Respiratory infection | Any workplace where people share indoor air, and customer-facing roles most of all | Ventilation and filtration, a sick leave policy people can use without arguing, and cleaning of shared surfaces |
| Mold and damp | Staff in a building after a leak, a flood, or a long-term humidity problem | Fix the water source first, then remediate. Air fresheners and paint are not remediation |
| Foodborne organisms | Kitchens, cafes, catering, and any office fridge with a shared responsibility for cleaning it | Temperature control, separation of raw and ready foods, handwashing facilities that are stocked |
| Animal and insect contact | Veterinary, grooming, landscaping, agriculture, and pest incursions in storage areas | Handling training, protective equipment for bites and scratches, and pest control on a schedule |
The federal bloodborne pathogens standard is the one small employers most often assume does not apply to them. It applies where occupational exposure to blood or other potentially infectious material is reasonably anticipated, and it asks for a written exposure control plan, engineering and work practice controls, protective equipment, and training. A designated first aid responder in a non-medical business can bring you inside it.
Illness data moves faster than injury data, which is a reason to revisit this category more often than the rest of the inventory. Federal survey figures put private industry illness cases at 148,000 in 2024, down 26.0 percent, driven by a 46.1 percent fall in respiratory illness cases to 54,000, the lowest count in that series since 2019. A category that can move by nearly half in a single year is not one to copy forward from an older inventory without looking.
Ergonomic Hazard Examples
Ergonomic hazards come from the fit between the job and the body: lifting, repetitive motion, awkward or static posture, sustained force, and equipment set up for an average person who does not exist. This category produces the largest single group of serious injuries in federal data.
| Ergonomic hazard | Example task | The cheap fix people skip |
|---|---|---|
| Manual lifting | Cases of stock lifted from floor level to shoulder height across a delivery | Store heavy items between knee and shoulder height, and break down pallets at waist level |
| Repetitive motion | Scanning, packing, chopping, stapling, or data entry for hours without variation | Rotate tasks within the shift rather than adding a stretch poster to the wall |
| Awkward posture | Reaching over a counter, kneeling to reach low shelving, twisting to place items behind you | Move the item, not the person. Most awkward postures are a storage decision |
| Static posture | A full day at a laptop on a kitchen table, or standing at a fixed register position | A separate keyboard and a screen at eye height, or an anti-fatigue mat and a footrest |
| Sustained force | Pulling a loaded cart with stiff casters, pinching a tool grip that needs both hands | Maintain the wheels and the tools. Force problems are usually maintenance problems |
| Vibration and cold combined | Outdoor tool work in winter, where cold hands mask the early symptoms | Shorter continuous exposure, warm breaks, and asking about numbness before it becomes chronic |
The tell for this category is behavioral rather than physical. People stop asking for help with a lift, start bracing a wrist, or quietly swap a task with a colleague. None of that reaches an incident report, so the only reliable route to finding it is asking, and a structured ergonomic assessment checklist gives the question a shape.
Psychosocial Hazard Examples
Psychosocial hazards are factors in the work environment that can cause stress, strain, or interpersonal problems for the worker, and they are treated as workplace hazards rather than as personal shortcomings. NIOSH names low job control, an imbalance between effort and reward, job insecurity, long working hours, job strain, and workplace violence among the examples (NIOSH science bulletin on work-related psychosocial hazards).
| Psychosocial hazard | What it looks like in a small team | Organizational control |
|---|---|---|
| Low job control | A role scripted minute by minute, with no say over sequence, pace, or method | Give discretion over how the work gets done, even where the deadline is fixed |
| Effort and reward imbalance | The person who covers every gap, gets thanked in the moment, and is never actually recognized | Fix pay, title, or workload rather than adding another thank you |
| Job insecurity | Rumors about hours, contracts, or funding that management neither confirms nor denies | Say what is known, on a date, including when the answer is that nothing has been decided |
| Long hours and overload | Sustained overtime treated as a temporary push for the third quarter in a row | Cap the hours, add the headcount, or cut the scope. There is no fourth option |
| Unpredictable scheduling | Shifts published late, on-call by group chat, closing and opening the next morning | Publish schedules earlier and protect the gap between a close and the next open |
| Violence and abuse | Aggression from customers or patients, threats, or a coworker whose behavior everyone works around | A reporting route with a named owner, a response people have seen work, and training for the roles exposed |
Two of those rows are usually treated as management problems rather than safety problems, which is the mistake. In 2018 survey data cited in the same bulletin, nearly 30 percent of workers frequently found their work stressful and around a quarter reported that they lacked decision-making power or could not take needed time off. The recommended response starts at the organizational level, because changing working conditions is described as more effective, broader in impact, and more sustainable than individually focused support alone.
Workplace violence has its own well-established typology worth knowing when you assess who is exposed. Type I is criminal intent by someone with no relationship to the business, Type II is a customer, client, or patient attacking a worker, Type III is worker on worker, and Type IV involves someone from an employee's personal life. Fatal violence was recorded in 733 cases in 2024, of which 470 were homicides. Which type your business faces determines the control, and it is the question workplace violence prevention training should start from.
One clarification, because the vocabulary collides. Psychosocial hazards are conditions of work that can cause harm. Psychological safety is a team climate where people can speak up without fear of humiliation. They are related and not interchangeable: a team with high psychological safety will report psychosocial hazards faster, which is useful precisely because the hazards still exist.
The Same Six Categories in Three Real Workplaces
The categories are constant and the contents are not. Here is what each one holds in three settings a small business actually occupies, which is the fastest way to see that no workplace scores zero anywhere.
| Category | Office and professional services | Warehouse or shop floor | Kitchen or food service |
|---|---|---|---|
| Physical | Glare, poor lighting on stairs, an air system nobody balances | Noise from equipment, heat in summer, vibration from tools and trucks | Heat at the line, noise from extraction, cold work in walk-ins |
| Safety | Cords, boxes on egress routes, a step ladder used for storage | Forklifts, unguarded machines, work at height, racking overloads | Wet floors, knives, hot surfaces, deep fryers, blocked exits |
| Chemical | Cleaning products, toner, aerosol dusters | Solvents, fuels, silica or wood dust, welding fume | Sanitizer concentrate, oven cleaner, carbon dioxide cylinders |
| Biological | First aid contact with blood, shared air, a fridge nobody owns | Pests in storage, mold after a roof leak, waste handling | Food pathogens, temperature abuse, pest incursion |
| Ergonomic | Static posture, laptops without a stand, long screen hours | Repeated lifting, awkward reaching into racking, cart pushing | Standing all shift, repetitive prep motions, carrying stock pots |
| Psychosocial | Overload, unclear priorities, lone working after hours | Shift patterns, production pressure, isolated night work | Late schedules, customer aggression, close then open the next day |
Read down your own column and the point lands. An office has entries in all six rows, and the two that people assume belong to industry, chemical and biological, are occupied by a closet of cleaning products and a first aid kit. The difference between settings is severity, not category coverage.
This is also the table that decides what your health and safety policy has to name. A policy that lists hazards you do not have and omits the ones you do is worse than a short one, because it signals to anyone reading it that nobody walked the building.
How to Find the Hazards in Your Own Workplace
Hazard identification is a walk plus a set of questions, done while the work is happening rather than before opening. The categories give the walk a structure so it does not become a search for the things you already worry about.
For a specific job rather than a whole site, the task-level version of this exercise is a job hazard analysis, which breaks a job into steps and pairs each step with its hazards and controls.
Ranking the Controls So the Fix Holds
Controls are ranked by how little they depend on a person doing the right thing under pressure. NIOSH sets out five levels, from elimination through substitution, engineering controls, and administrative controls, down to personal protective equipment, and describes the upper levels as more effective because they control exposure without significant human interaction (NIOSH, Hierarchy of Controls).
| Level | What it means | Example on a real hazard | Holds up when the week gets busy? |
|---|---|---|---|
| 1. Elimination | Remove the hazard entirely | Stop storing stock above shoulder height, so the ladder is no longer part of the job | Yes, permanently |
| 2. Substitution | Replace it with something less hazardous | Swap a solvent degreaser for a water-based product that does the same job | Yes, once purchasing is updated |
| 3. Engineering controls | Change the workplace or the equipment | Fit a guard and an interlock, add local extraction, install a lift table | Yes, if it is maintained |
| 4. Administrative controls | Change how people work | Rotate a repetitive task, add rest breaks in heat, write a lockout procedure | Only while someone enforces it |
| 5. Personal protective equipment | Protect the individual at the point of exposure | Gloves, hearing protection, eye protection, respirators | Only while it is worn, fitted, and replaced |
Two things follow. The first is a diagnostic: read the control column of your own hazard list, and if every line says training or protective equipment, you have documented the workplace rather than improved it. At least one serious hazard should have a control that physically changed something.
The second is that protective equipment is a legitimate control in its place, not a failure. It belongs where higher controls are not feasible, while they are being built, where safe work practices alone are insufficient, and in emergencies. The mistake is reaching for it first because it is the fastest thing to buy, which is the same instinct that fills a safety training plan with slides about being careful.
What to Write Down
A hazard you identified and did not record is one that leaves with the person who noticed it. The written artifacts are also what a penalty calculation looks at, since the good faith reduction is assessed on evidence rather than intention.
There is no single federal rule demanding one master hazard document, but several standards require documented assessment in their own areas, and the personal protective equipment rules are the clearest: assess the workplace for hazards that make protective equipment necessary, then verify that assessment in writing. In my experience the assessment gets done in somebody's head and the written certification never does, which is the version that shows up in an OSHA violation file.
Here is the inventory sheet I use, organized by the six categories so that an empty section is a deliberate answer rather than an oversight.
Three records make the inventory operational rather than decorative. A dated training record showing who was trained on which hazard, which a training matrix handles for a small team. An incident and near miss log, because the near miss is the cheapest hazard report you will ever receive. And a photograph of each correction, which takes ten seconds and answers a question you cannot otherwise answer a year later.
Keep them with the rest of your compliance paperwork rather than in a safety silo. If you already run compliance onboarding, the hazard briefing for a new hire belongs in that flow, on day one, where it gets acknowledged and dated automatically.
Where Small Employers Get This Wrong
The same six patterns come up.
Writing a list that is entirely safety hazards is first. It is the category instinct reaches for, and it leaves chemical, ergonomic, and psychosocial hazards unexamined in a business that has all three.
Assuming office equals safe is second. An office has entries in all six categories, and the ergonomic and psychosocial ones there produce real days away rather than dramatic ones.
Inspecting when the workplace is quiet is third. The hazard is the pallet in the fire route at 4 p.m., not the clear floor at 7 a.m., and an inspection scheduled for convenience finds the second one every time.
Controlling everything with training and protective equipment is fourth. Both sit at the bottom of the ladder, both depend on a person doing the right thing on a bad day, and both are chosen because they are quick to buy rather than because they work best.
Treating scheduling and workload as management topics is fifth. They are recognized hazards with organizational controls, and the fix is capping the hours or adding the headcount rather than sending someone on a resilience course.
And never reviewing the list is last. New equipment, a new process, a new location, an injury, or a change in who does the work all change what is in the building, and an undated inventory cannot tell you which of those has happened since anyone last looked. If your operation has reached the point where spreadsheets are creaking, health and safety software takes over the review cycle; below that, a calendar reminder and an owner will do it.
Frequently Asked Questions
What are examples of workplace hazards?
Common examples include a trailing extension cord across a walkway, an unguarded blade on a bench saw, bleach decanted into an unlabeled bottle, blood on a surface after a first aid incident, a case of paper lifted from floor level thirty times a shift, and a lone closing shift with cash on the premises. Those six are deliberately taken from six different categories: safety, safety, chemical, biological, ergonomic, and psychosocial. Noise loud enough to make people raise their voices and a warehouse with no cooling in July belong on the same list. Most hazard lists written inside small companies contain only the first two kinds, which is why the categories are worth using as a checklist rather than as vocabulary.
What are the six types of hazards in a workplace?
Physical hazards are forms of energy acting on the body, such as noise, heat, cold, vibration, and radiation. Safety hazards cause sudden traumatic injury: walking surfaces, heights, machinery, electricity, and vehicles. Chemical hazards are substances that harm on contact or inhalation, including ordinary cleaning products. Biological hazards are living organisms and what they leave behind, from bloodborne pathogens to mold. Ergonomic hazards come from the fit between the job and the body, such as lifting and repetitive motion. Psychosocial hazards come from how work is organized and led. Some frameworks list five by folding safety into physical, which is the same content sorted differently.
What is the difference between a hazard and a risk?
A hazard is the thing that has the potential to cause harm. Risk is the combination of how likely that harm is and how bad it would be if it happened. A drum of solvent on a shelf is a hazard whether or not anyone goes near it. The risk changes with how often it is decanted, whether the area has ventilation, and who does the decanting. The distinction matters in practice because it tells you what to write in each column of an assessment, and because you control risk by acting on the hazard rather than by rewording the description of it.
What are examples of ergonomic hazards?
Manual lifting from floor level, carrying awkward loads through doorways, repetitive scanning or packing motions, sustained keyboard work at a screen set below eye level, kneeling or overhead reaching, prolonged standing on hard floors, and hand tools that require a hard pinch grip. Federal injury data for private industry over 2023 and 2024 put overexertion, repetitive motion, and bodily conditions at 946,290 cases involving days away, restricted duty, or transfer, the largest event group in the survey. These injuries build over weeks, so the useful signal is people quietly changing how they do a task rather than an incident report.
What are psychosocial hazards at work?
Psychosocial hazards come from how work is designed, scheduled, and supervised, and the federal occupational health agency defines them as environmental factors that can cause stress, strain, or interpersonal problems for the worker. The examples it names include low job control, an imbalance between effort and reward, job insecurity, long working hours, job strain, and workplace violence. In practice they show up as a role with no discretion, overtime treated as temporary for the third quarter running, schedules published late, and aggression from customers that nobody logs. They are treated as hazards rather than as personal resilience problems, and the recommended response starts with changing working conditions, because organizational solutions are described as more effective, broader in impact, and more sustainable than individually focused support alone.
How do I identify hazards in a small workplace?
Walk the workplace while the work is actually happening, take one hazard category at a time, and ask the people doing each job what nearly went wrong recently. Then read your own records: incident reports, first aid entries, insurance claims, maintenance requests, and complaints. Cover the tasks nobody performs daily, such as cleaning a machine, changing a light, or receiving a delivery in the rain, because those are the ones no routine has been built around. Write each finding as a scenario naming the place, the person exposed, the trigger, and the likely injury, then date the sheet and assign an owner to every fix.
Does OSHA require a written hazard assessment?
There is no single federal rule requiring one written hazard assessment covering an entire workplace, but several standards require documented assessment in specific areas, and the personal protective equipment rules are the clearest example: the employer must assess the workplace for hazards that make protective equipment necessary and verify that assessment in writing. The general duty clause of the Occupational Safety and Health Act separately requires a workplace free from recognized hazards likely to cause death or serious physical harm, which cannot be met without some form of assessment. A dated inventory also supports the good faith factor in any penalty calculation.
