The 5 OSHA Workplace Hazards

Under the right circumstances, virtually anything could become hazardous in the workplace. With sensible employee behavior and workplace conditions, however, the workplace hazards that the Occupational Safety and Health Administration (OSHA) warn against fall into just five main categories. We’ll review them below, and provide suggestions for mitigating dangers for each.

#1: Safety Hazards

(slips, trips and falls, faulty
equipment, etc.)

Safety risks refer to the conditions or substances found in the work environment which can pose danger of injuries. From falling objects to wet floors, these seemingly innocuous everyday risks have the potential to cause serious bodily harm. To minimize these hazards, there are a few things you can do:

  1. Never leave machinery unattended while in use
  2. Practice safety while working from heights
  3. Mandate the use of safety gear and safety apparel, like hardhats, and safety glasses
  4. Have your electrical wiring inspected regularly
  5. Provide the proper signage (like wet floor signs) to notify employees of spills, and clean them up promptly

Safety Hazards include:

  • Spills on floors or tripping hazards,
    such as blocked aisles or cords
    running across the floor
  • Working from heights, including
    ladders, scaffolds, roofs, or any
    raised work area
  • Unguarded machinery and moving
    machinery parts; guards removed or
    moving parts that a worker can
    accidentally touch
  • Electrical hazards like frayed cords,
    missing ground pins, improper
  • Confined spaces
  • Machinery-related hazards
    (lockout/tagout, boiler safety,
    forklifts, etc.)

#2: Biological Hazards

(mold, insects/pests,
communicable diseases, etc.)

These types of hazards tend to be exclusive to specific work environments. Particularly, anyone who works with infectious plants, people, or animals may be regularly exposed to biological hazards. Examples of occupations could include laboratory workers, daycare assistants, and personnel in hospitals, doctor’s offices, or nursing homes.

Coming into contact with substances like blood and other bodily fluids, animal droppings, bacteria and viruses, or fungi can put an individual at risk of becoming ill. To minimize these risks, it’s essential that you establish a protocol for handling biohazards and potentially infectious material. Additionally, make sure necessary supplies like disposable gloves are easily accessible. Sorbents can be used to clean up bio-hazards.  These powerful granules absorb the liquid, making them easy to clean-up.

Types of things you may be exposed to

  • Blood and other body fluids
  • Fungi/mold
  • Bacteria and viruses
  • Plants
  • Insect bites
  • Animal and bird droppings

#3: Physical Hazards

(noise, temperature extremes,
radiation, etc.)

Physical hazards are environmental factors which can cause injury without direct contact. For instance, radiation, temperature extremes, consistent loudness, and prolonged exposure to sunlight or ultraviolet rays all fall into this category. These are commonly considered the most difficult to detect, because signs don’t always present themselves right away.Like the other hazards listed here, reducing your employees’ risk of being exposed to physical hazards comes down to providing protection.

Hearing protection, for instance, should be considered mandatory for any individuals working around loud machinery. In settings where MEFs and microwaves are routinely emitted, employers must develop practices their teams can follow to limit exposure.

Physical Hazards include:

  • Radiation: including ionizing, nonionizing
    (EMF’s, microwaves,
    radiowaves, etc.)
  • High exposure to sunlight/ultraviolet
  • Temperature extremes – hot and cold
  • Constant loud noise

#4: Ergonomic Hazards

(repetition, lifting, awkward
postures, etc.)

Like physical hazards, ergonomic hazards may develop over time. Back strain and similar musculoskeletal disorders are often attributed to repetitive workplace motions. Even individuals who work desk jobs aren’t immune to suffering from back pain.

To combat ergonomic hazards, employers can offer training from specialists to help employees understand the importance of proper lifting techniques and posture. More and more employers are also exploring standing desk options to prevent associates from experiencing health complications associated with prolonged sitting.

Ergonomic Hazards include:

  • Improperly adjusted workstations and
  • Frequent lifting
  • Poor posture
  • Awkward movements, especially if
    they are repetitive
  • Repeating the same movements over
    and over
  • Having to use too much force,
    especially if you have to do it
  • Vibration

#5: Chemical/Dust Hazards

(cleaning products, pesticides,
asbestos, etc.)

Some chemicals are naturally more potent than others. While certain types are only dangerous when ingested or a person comes into direct contact with them, others are dangerous when simply inhaled. If your workforce uses chemicals regularly, you can keep employees safe by:

  1. Clearly labeling all chemicals
  2. Developing a protocol for handling chemicals
  3. Providing employees with the proper safety gear (respirators and gloves, for instance) to wear while in the presence of chemicals

Beware of:

  • Liquids like cleaning products, paints,
    acids, solvents – ESPECIALLY if
    chemicals are in an unlabeled
  • Vapors and fumes that come from
    welding or exposure to solvents
  • Gases like acetylene, propane, carbon
    monoxide and helium
  • Flammable materials like gasoline,
    solvents, and explosive chemicals.
  • Pesticides

7 Ways to Reduce Contamination in Cleanrooms

Reduce Contamination in Cleanrooms

A cleanroom bears its name for a reason: its very purpose is to stay sanitary and free of contaminants to maintain a stable work environment. Because employees handle sensitive equipment and components in these critical areas, keeping contaminants at bay is essential to everyday workflow, and ultimately, maintaining profitability.

It may come as no surprise that your employees are the most common source of contamination in your cleanrooms. What you may find surprising, however, are the simple steps you can take to minimize contamination risks. Let’s take a look at some of the most effective tips, below.

1.       Practice Good Hygiene

Humans naturally produce particles. Our bodies shed contaminants, producing detritus like skin flakes and particles from hair products, cosmetics, and lotions. Thus, while good hygiene can limit the level of contaminants spread in the cleanroom, it’s also important to consider ways in which certain steps of getting ready might be skipped or altered for the purpose of limiting contaminants. Even perfume and cologne, for instance, can produce contaminants. Since 75-80% of particles found in cleanroom inspections are produced by personnel, it’s a good idea to establish a set of hygiene recommendations for your employees to follow.


2.       Be Especially Mindful of Hands

A good portion of cleanliness violations result from bare hands touching surfaces, then transferring these particles onto garments before they enter the cleanroom. To make sure your employees aren’t contaminating anything that will be worn inside your critical environments, consider installing no-touch sensors in the areas where your employees don their cleanroom gear. This will allow them to still wash their hands without picking up any excess particles in the process. Cleanroom Gloves are used in areas that have specific requirements for low contamination risk.

Cleanroom Gloves are disposable gloves designed and clean-processed for contamination control and sterility required work environments including cleanrooms, laboratory and ESD work areas. Minimize sub-micron particle contamination by using gloves designed and manufactured for Cleanrooms.

3.       Don Gear Properly

The way your employees put their disposable apparel on is just as important as the garments themselves. Because particles are also impacted by the pull of gravity, donning procedures should start at the top. Employees can then work their way down. While each company’s donning procedures may be unique to its specific needs, it’s a good idea to adopt a head-to-toe procedure to prevent contaminants from falling and settling on clean shoe covers.


4.       Limit Speaking

A quiet cleanroom doesn’t just boost productivity; it also has the power to reduce contaminants. Consider the fact that loud speaking of just 100 words (less than a minute of normal conversation!) can produce up to 250 particles of saliva. Of course, there are also some contaminants which may not be avoided, such as coughs and sneezes, which produce roughly 5,000 and 1,000,000 saliva particles, respectively. What’s a simple way to limit contamination from saliva particles in your cleanroom? Wear a face mask designed for Cleanrooms.

5.       Designate “Cleanroom Only” Supplies

Cleanroom Pens

Taking a pen from outside the cleanroom into the critical work environment might seem harmless, but employees who do so will also unintentionally bring a plethora of contaminants inside with it. Not only should you have cleanroom pens, cleanroom notebooks, and any other tools or instruments designated specifically for cleanroom use only, but you should also make sure they’re compliant with your standards. In other words, the supplies you’re using should also have been produced in a cleanroom environment.

Cleanroom paper packaged in class 10 cleanrooms, for instance, is considered safe for use in class 10 cleanrooms or higher. Cleanroom paper products are impregnated and coated with a polymer. This keeps the paper from generating tiny particulates when written on. Keep your area clean of paper contaminants by using documentation designed just for Cleanrooms.

6.       Take Care When Entering & Exiting

After employees enter and exit cleanrooms, encourage them to take an extra moment to ensure doors are tightly shut. It’s a good practice to make sure the door leading to the changing room is also closed before the cleanroom door is opened to prevent additional particles from making their way into the buffer area. In fact, you can further eliminate the spread of contaminants by separating your gowning room into three distinct areas. One for the non-sterile space directly outside of the room, where employees can keep personal items and clean shoes. The second space is the sterile “dirty” area, where employees prepare for gowning. Finally, the last space should be designated for gowning and taking final preparations before entering.

7.       Move Slowly

The more rapidly movement occurs inside the cleanroom, the more particles will be given off. To combat excess contamination, employees should move slowly and deliberately as they approach work stations. They should also be encouraged to enter and exit cleanrooms slowly.


By incorporating these tips into your cleanroom protocol, you might be able to significantly reduce the number of contaminants inside. You can find cleanroom documentation, cleanroom disposable apparel, and more supplies suitable for cleanroom use online through Harmony Business Supplies.

3 Common Respirator Myths Debunked

3 Common Respirator Myths Debunked

Respirators are used to protect the wearer from inhaling harmful substances, including infectious particles and chemical vapors. With varying degrees of protection, respirators are available in many different types. While particulate respirators are used to filter only particles (dust and mist, for instance), chemical cartridge respirators (also known as “gas masks”) actually purify the air while you inhale.

Finding the right respirator to suit your needs will depend on the nature of your application. Just as importantly, you’ll also need to carefully follow the device’s guidelines to ensure full protection during use. There are some myths surrounding the proper ways to wear, use, and enforce respirators, many of which can actually be dangerous if believed. Here, we’ve collected and debunked some of the most common respirator myths:

3 Safety Respirator Myths:


MYTH: My company doesn’t need a respiratory protection program if employees wear masks voluntarily.

MYTH: My company doesn’t need a respiratory protection program if employees wear masks voluntarily.


TRUTH: The Occupational Safety and Health Administration (OSHA) sets forth requirements which employers must follow to keep individuals safe against the exposure of harmful air pollutants. Specifically, OHSA has a Respiratory Protection Standard which enforces respirator regulations. For instance, in settings where employees could be exposed to harmful fumes, vapors, smokes, sprays, and mists, the company must have a documented plan to explain how their respiratory protection program will be governed. This should also include procedures, specific types of equipment to be worn, care and use of the equipment, and medical evaluations for employees to verify their ability to wear respirators. Thus, even if your employees willingly wear respirators, government regulations still require you to have a plan in place.



MYTH: My facial hair won’t hinder respirator effectiveness.

MYTH: My facial hair won’t hinder respirator effectiveness.


TRUTH: It’s possible beards and mustaches could leave you more exposed to air pollutants. Here’s why: in order to keep you fully protected, the respirator needs to form an air-tight seal against your skin. Beards, clothing, and any other blockage preventing the seal from coming into direct contact with your skin can become an issue. By preventing a tight seal or blocking the exhalation valve, facial hair can allow contaminated air to leak into your respirator.



MYTH: I don’t need to change my respirator’s cartridge until I can smell the chemical while wearing it

MYTH: I don’t need to change my respirator’s cartridge until I can smell the chemical while wearing it.

TRUTH: Certain types of respirators use cartridges to purify the air. While they offer a high level of protection, they become less effective over time as the cartridge wears out. Thus, waiting until the cartridge is no longer working essentially defeats the purpose of wearing a respirator, as it no longer protects the wearer effectively. Moreover, using employees’ ability to detect smells is an unreliable method for changing cartridges, as they may be less sensitive to the fumes after working with them for a long time. OHSA mandates that employers should have a cartridge change schedule in place, so they can be replaced prior to losing their effectiveness.


If you’re in need of reusable respirators and cartridges to keep your employees protected, look no further than Harmony Business Supplies. Dozens of options are available online to accommodate every application, and a product specialist can help you if you’re not sure which model is right for your needs.

Industrial Uses for Foam-Tipped Applicators

Industrial Uses for Foam-Tipped Applicators

Industrial Uses for Foam-Tipped Applicators

There are countless areas throughout manufacturing and industrial environments which need to be cleaned regularly. However, many of these are tight, hard-to-reach or delicate spots, and regular cleaning tools are simply too large or cumbersome to do the job. For these reasons, many companies turn to foam-tipped applicators for precise, effective cleaning.

Foam swabs are the right tool for any jobs that demand precision, detailing, and cleanliness. The foam is soft and non-abrasive, making it safe for use on even your most sensitive manufacturing or industrial components. They’re also ideal for cleanroom use, as they feature thermal bonding to prevent contamination. While foam applicators are soft enough for gentle cleaning, they’re still sturdy enough to avoid bending, flexing, and folding during regular use. They can be used either wet or dry. With many different configurations available, there’s a specific swab available to meet the needs of any application.

Some industries that can benefit from foam-tipped applicators include printing, precision manufacturing, electronics, semiconductors, aerospace, pharmaceuticals, and biotechnology. Below, we’ll discuss some of the many of the general purposes these swabs are used for.

Apply Solutions with Foam Applicators

When you need to precisely apply cleaning solvents, adhesives, paints, or lubricants, a regular cleaning cloth won’t do. Foam swabs like the Puritan foam-tipped applicator or the CleanTex Large Foam Swab have an open-cell structure which creates an optimal holding capacity, making it easier for you to perform precise cleanings and applications. They’re also free of adhesives and shred-resistant to keep contaminants away from small machine components.

Clean Small Parts with Foam Swabs

Small, grooved areas in fiber optics can benefit from non-abrasive foam applicators like the TekniSwab cleanroom foam swab or the Chemtronics Foam Flextip Swab. With a conical screw tip, the applicator can successfully remove buildup and excess production material from extremely tight spaces.

Foam Tipped Swabs to Remove Contaminants

Virtually any industrial or manufacturing setting has surfaces and components that need to be cleaned regularly for optimal efficiency. Chemtronics Foamtips Swabs are lint-free and non-abrasive; perfect for cleaning. In the manufacturing of electronic components, for instance, few particles can be present during critical phases of production, and even the presence of static could compromise your products. To limit contaminants and control static in these environments, swabs like the Puritan anti-static foam swab are a leading choice.

Now that we’ve discussed some of the general ways foam tipped swabs can be used in the industrial or manufacturing sectors, let’s look briefly at just a few specific solutions they provide by industry:

Some Foam Tip Swab Uses by Industry

Circuit Boards & Flat Panels (& Electronics)

During the production and handling of flat-panels and circuit boards, small components like the interiors of orifices and tubes must be cleaned. Because they are inaccessible by larger cleaning instruments, foam-tipped swabs are often the go-to cleaning tool for these minute spaces.


In industries like aerospace, employees may handle coated lenses regularly. To perform a thorough surface cleaning without impacting the lens coating, you’ll need to use a nonabrasive foam tip. They’re also useful for cleaning small mirrored surfaces and fiber-optic sensors.

Semi-Conductor Manufacturing

Before devices produced in semi-conductor manufacturing can be sealed, their O-ring chambers must be cleaned. Many manufacturers turn to static-free foam-tip swabs to perform the task safely and efficiently.


No matter your needs, Harmony Business Supplies has dozens of foam tip applicators to help you maintain a clean, sanitary work environment. To explore their options, browse through our swabs online now or get in touch with a product specialist today.
