Choose hand protection solutions via form, function, and fit.

Safety Professionals, 'We've Got a Problem'

 

 


















Astronauts wouldn't dare go into their work "space" without wearing protective gear, especially hand protection, which is a critical component of a space suit. Even though space gloves are incredibly bulky and non-dexterous–a common work glove complaint of workers–astronauts always wear them because they understand the danger and life-threatening consequences of not wearing safety gear. For astronauts, it's simply not an option to forego wearing space PPE because it literally saves their lives.

 

How can we channel the astronaut's "must wear PPE" attitude toward safety among our global workforce? How can we motivate workers to willingly wear their hand protection like astronauts do? We motivate them by providing them with the appropriate glove for the task. That glove should be comfortable and fit properly.

 

We encourage them to wear it through proper training and the constant reminder that hand protection is a crucial part of the worker's well-being. After all, if someone suffers a serious hand injury, such as losing a finger or the functional use of a hand, the quality of his or her life declines immensely. Hand protection protects a person’s well-being, not just the hands, fingers, and wrists.

 

Safety Professionals, 'We've Got a Problem'

In the movie Apollo 13, directed by Ron Howard and starring Tom Hanks, the phrase "Houston, we've got a problem," entered the mainstream culture. Although hand protection is evolving quickly like spacesuits due to technological and scientific breakthroughs that improve protection, comfort, and dexterity, the statistics for hand injuries still remain problematic.

 

According to the Bureau of Labor Statistics (BLS) and other sources, here are some of the numbers that reveal the severity of hand injuries:

 

  • Seventy percent of workers who experience hand injuries are not wearing gloves when the injury occurs.
  • Thirty percent of workers are wearing inadequate or inappropriate hand protection.
  • One million workers are sent to emergency rooms annually because of hand injuries.
  • There are 250,000 serious injuries to fingers, hands, and wrists each year, propelling hand injuries to the second-leading cause of work-related injury (back and neck injuries take first place).
  • The average hand injury claim exceeds $13,000 when medical claim and workers’ compensation claims are coupled together.
  • The National Safety Council (NSC) reports that a severed tendon typically costs $70,000, a laceration $10,000, and stitches $2,000.

 

Hand Protection Solutions Via Form, Function, and Fit

 

Spacesuits have evolved into machines of impressive complexity, even becoming miniature spacecraft that fly independently. Hand protection has grown increasingly complex, too, with all of the choices offered in the marketplace. From super yarns for high levels of cut protection to advanced palm coatings and thermal plastic overlays, choices for hand protection are immense and varied.

 

Astronauts know that NASA has chosen their spacesuit and gloves with methodical and scientific reasoning. After all, the astronaut's life depends upon it. Safety professionals should specify hand protection with methodical and scientific care in order to choose the perfect glove for the worker in his or her job environment.

 

Providing workers with the right gloves for the application will motivate them to willingly wear their gloves. The safety professional's understanding of the importance of glove form, function, and fit leads to accurate glove selection and increased worker compliance.

 

Form: What is Your Glove Made of? Materials, Fibers, and Coatings

 

Materials

 

When selecting hand protection, safety professionals must consider the material of the glove. Ideally, the material should provide comfort, the appropriate protection for the task, and dexterity. Common glove materials include natural leather, synthetic leather, and fabric gloves that are machine stitched.

 

Natural leather comes from cow, goat, or pig. It is soft to the touch, tear resistant, durable, and has high tensile strength; however, like human skin, it doesn't provide high levels of cut resistance. Synthetic leather has similar properties to natural leather but is man-made.

 

There are many synthetic and natural fibers that are used to make fabric glove shells. Glove shells are knitted on a flat head knitting machine and are measured by the gauge (ga) of the shell: The smaller the gauge, the thicker the shell. Seven gauge is the thickest shell and 18 gauge is the thinnest, lightest-weight shell. If dexterity is of paramount importance, then you will need to select a glove with a high gauge.

 

Fibers

 

Just as our hands are made of tendons, ligaments, bones, and nerves, glove shells are composed of fibers. Not all fibers are created equal, and picking the wrong fiber for your glove is a common error in fabric glove selection. Two primary types of fibers are filament fibers and staple fibers.

 

Filament fibers are longer, lined up, and bundled. They produce products with higher tensile strength that resist breakage under tension. Staple fibers are shorter in length and are mechanically twisted to form a variety of sizes.

 

Machine knit glove shells can be made from many different types of materials, including natural fibers, synthetic fibers, and fiber blends. Natural fibers are plant based and include cotton, bamboo, wool, silk, and hemp fibers. Man-made synthetic fibers, such as polyester and nylon, are frequently used in glove shells.

 

Typical fibers for blended yarns include cotton, acrylic, nylon, and polyester. The blend of polyester, nylon, and cotton fibers offers extra durability and strength while maintaining the comfort benefits of cotton. Blends help manufacturers develop a variety of gloves to satisfy a wide range of applications.

 

Coatings 

 

Coated gloves are ideal for jobs that require a high degree of touch sensitivity, dexterity, and a superior grip. Industrial applications include general assembly, painting, the handling of small oily parts and components, horticulture, machining, and maintenance.

 

Glove coatings:

  • improve the gripping power of a glove
  • increase the glove’s resistance to puncture and abrasions
  • offer protection from liquids and chemicals

 

Common glove coatings include nitrile, latex, and polyurethane (PU).

 

Nitrile gloves, an industry staple, hold up well to gasoline, turpentine, acids, bases, oils, and diesel fuel. They are generally stronger and more puncture resistant than latex gloves. They are available in different finishes, such as smooth nitrile, foam nitrile, and sandy foam nitrile.

 

Latex gloves, which are one of the most recognized glove materials in the world, resist acetone, thinners, and ketones but often cause allergic reactions if the wearer is over-exposed to the product. Semi-smooth texture is extremely flexible and provides superior dexterity and sensitivity. Latex gloves are also available in different finishes, including foam, sandy foam, and crinkle latex. Rough finishes on gloves improve the worker’s grip.

 

A PU coating can be silicone free and has a low-particulate shed, which reduces risk of contamination from the dip itself. The coating "strikes through" onto the inside of the glove, which can lead to heat retention and sweating. Not as durable as nitrile or latex, PU gloves can be used for inside light duty, detailed assembly, inspection, light fabrication, and box/small parts handling.

 

 

Function: 'Danger, Will Robinson'—Matching the Glove to the Risk

 

Since we don't have a robot (yet) that informs us of impending danger as Will Robinson does in the Netflix adaption of Lost in Space, choosing the right glove for your safety program requires safety professionals to conduct a proper PPE hazard and risk analysis, also known as a "risk assessment."

 

Put on your detective hat and ask these questions to discover the dangers lurking in your workspace.

 

  • What specific risks are present in your facility that could put your employees' hands, fingers, thumbs, and wrists in danger?
  • Can these risks be eradicated via engineering or administrative controls, such as putting up guardrails on machinery (engineering) or regular inspections of work spaces by safety officers to ensure employees are wearing their gloves (administrative)?
  • What glove features are required to safely protect against the risk, especially if engineering or administrative controls aren't feasible or possible?
  • Do you need a Cut Level A3 or does the task require A7 cut protection? Do you need a coated glove with a crinkle latex finish or will a typical coated glove work? Does the glove need a thermal layer? Does it need thermal plastic overlays for enhanced impact resistance?

 

The questions are many and the answers can be complicated but you need to know: You are not alone. Most leading glove manufacturers and suppliers have product managers, product champions, and trained safety specialists who can help with risk assessments and specify the perfect glove for your safety program. Don't hesitate to call and get the support you need to help protect your workforce.

Fit: If the Glove Fits, Comfort and Compliance Skyrocket

 

Just as people don't like to wear shoes that are too small or too large, they don't like to wear gloves that don't fit. However, far too many workers are thrown into situations where they are wearing work gloves that don't fit.

 

Proper sizing of work gloves will manifest itself into improved compliance statistics. Gloves that are too small or too large can interfere with productivity and lead to hand injuries. Improperly sized gloves are uncomfortable so workers will frequently remove them. Gloves that are too large can often get caught in machinery, which can cause serious hand injuries. Gloves that are too small can cause hand fatigue. It seems like common sense but far too many workers wear gloves that don't fit them. Gloves that are too tight may lead to increased sweating, which nobody likes.

 

Determining proper glove size

Encourage employees to measure their hands using a sizing chart. To determine the proper glove size, use a soft cloth tape measure to measure your dominant hand.

 

For gloves that come in numbered sizes, match your measurement to the size listed. For example, if the measurement is seven inches, then select a size seven glove. If the measurement is over seven inches, then choose the next size larger to avoid hand fatigue, in this case a size eight.

 

If the gloves are offered in lettered sizes, such as S, M, L, XL or XXL, convert to a numerical size using a size chart. Sizes can be different among manufacturers, so you will want to confirm the sizing chart that your supplier uses. Some charts include half sizes and some do not. 

 

The Goldilocks Zone and Gloves

NASA often refers to the Goldilocks Zone in space when trying to find new planets that are "just right" for human habitation. Gloves have a Goldilocks Zone, too. Selecting the glove with the specific features that are "just right" for the task and selecting the glove that fits the worker's hand "just right" will do wonders for your safety program.

 

Couple this with motivational training that reminds workers that safety is more than just following OSHA rules and avoiding citations or HR reprimands. Wearing PPE at work is often life-saving, like spacesuits, especially when the PPE protects against struck-by accidents, slips and falls, and head injuries.

 

Remind your workers on a regular basis that safety is also about maintaining the worker's well-being and quality of life, especially when it pertains to vision, hearing, and hand injuries, which often aren't life threatening. But these types of injuries negatively compromise your lifestyle and your relationships at home and at work.

 

Finding new, perfect planets is not an easy task. But finding the perfect glove can be, especially when you reach out to PPE manufacturers, suppliers, and distributors who are knowledgeable and passionate about hand protection. You are not alone!

Save Lives & Reduce Injury with FR/AR Workwear

Burned in a Flash

Save Lives & Reduce Injury with FR/AR Workwear

Workplace burn injury and fatalities are frequently the result of the worker’s clothes catching on fire from two primary workplace hazards: flash fire and electric arc flash also referred to as “thermal incidents.” 

 

When a thermal incident ignites non-flame resistant clothing, the worker is exposed to injury from the burning or the melting of the garment. If a garment continues to burn, the area of injury increases and can also result in internal injuries, such as lung and airway damage.

 

The American Burn Association (ABA) reports that over 486,000 people receive medical treatment for burns each year, and survivors with 40 to 60 percent body burn typically stay 54 days in the hospital with an average cost of $780,000.

 

OSHA says that ten percent to 45 percent of all burns happen at work and that 40 percent of workplace burn fatalities are from fires and explosions. It is estimated that 50 percent of all jobsite electrical injuries are due to arc flash, resulting in 2,000 people visiting burn centers each year for treatment.

 

Burn injuries are expensive, debilitating, often life-threatening and in too many cases deadly. Arc-Rated (AR) and Fire-Resistant (FR) clothing can help reduce the risk of burn injury from thermal incidents and is required in many industries, including oil and gas, electric power utilities, metallurgy, mining, paper and pulp, food processing, paint, and for all workers who come in contact with energized electrical equipment.

 

What is a Flash Fire?

The National Fire Protection Association (NFPA) defines a flash fire as “a type of short duration fire that spreads by means of a flame front rapidly through a diffuse fuel, such as dust, gas, or the vapor of an ignitable liquid, without the production of damaging pressure.” 

 

Combustible dust is also a flash fire hazard. If it is ignited within a confined space, it can explode and is a potential threat within industries where sanding, polishing or grinding occur.

 

Although a flash fire is only three seconds or less, it can produce temperatures from 1000 degrees F to 1900 degrees F. Don’t let the three seconds fool you. If a worker is not wearing flame-resistant clothing (FRC), his or her clothing can ignite during that three seconds and continue to burn even though the thermal incident may be over. It is ironic that most burn injuries result from the clothing igniting or melting instead of the incident itself, which is short-lived.

 

Know This Standard

The NFPA 2112 standard is the national consensus “Standard on Flame-Resistant Clothing for Protection of Industrial Personnel against Short-Duration Thermal Exposures from Fire.” 

 

PPE that is compliant with this standard, such as garments, shrouds, gloves, and balaclavas, resist ignition and reduce the severity of burn injuries. This standard specifies test methods, certification standards, minimum design and performance requirements, and labeling instructions.

 

FR fabrics fall into two categories: treated or inherent. Treated FR fabrics are fabrics in which flame-retardant chemicals are added after the fabric has been woven or knitted. An FR fabric that is considered inherent is made of fibers that are flame-resistant due to the chemical structure of the fibers.

 

What is an Electric Arc Flash?

The electrical industry is not a stranger to arc flash hazards as many of daily activities expose workers to risk. Some of these risks include voltage testing, removing circuit breakers, and opening bolted panel covers. The NFPA describes an arc flash as “an electric current that passes through air when insulation or isolation between electrified conductors is no longer sufficient to withstand the applied voltage.”

 

NFPA 70E standard is the national consensus standard for electrical safety in the workplace. Originally developed at OSHA's request, NFPA 70E helps companies and employees avoid workplace injuries and fatalities due to shock, electrocution, arc flash, and arc blast, and assists in complying with OSHA 1910 Subpart S and OSHA 1926 Subpart K.

 

FR versus AR

According to the current NFPA 70E standard, all arc-rated clothing must also be flame-resistant to qualify for the arc rating. In other words, all AR clothing is FR, but not all FR clothing is AR.

 

Like FR clothing, all AR clothing must provide both a thermal barrier that insulates workers against burns and the fabric must be self-extinguishing. However, AR garments are required to carry an arc rating on the garment label.

 

All fabrics specified for use in AR workwear are tested according to ASTM F1959. The arc rating can be reported in one of two ways:

 

Arc Thermal Protective Value (ATPV), which is a rating of the arc burn protection capability of garment. The higher the arc rating, the more protection a garment gives because the fabric has demonstrated a higher resistance to catching on fire. The ATPV is expressed in calories per centimeter square (cal/cm2) and represents the thermal exposure from an electric arc that will create a second-degree burn in human tissue.

 

Energy of Breakopen Threshold (EBT) — If the ATPV can’t be calculated because the fabric breaks open, the energy that causes the fabric to break open is called EBT. Like ATPV, the higher the rating, the greater the protection.

 

Keep in mind that while both values can be reported, only one arc rating is given to fabric and that rating is based on the first value that is reached, which is considered the “lowest value.” According to the ASTM F1506 standard, the lowest value will be used on the garment’s label. 

 

When considering the NFPA 70E standard, approximately 90 percent of all electrical trade workers generally fall into Category 1 and 2, meaning they require arc rated clothing with an ATPV rating of 8 or higher. 

 

The Future of FR Workwear

FR/AR clothing and the textile industry have seen vast improvements and impressive technological advances in manufacturing, design, and testing in the past 30 years. This trend will continue as new fabrics and fiber blends are created to enhance protection levels, durability, and comfort.

 

Style and comfort, provided protection is not compromised, is perhaps where the future points -- both are such a critical component of compliance. Designing and developing stylish and comfortable FR Workwear, including FR denim jeans, shirts, and coveralls, will lead to improved employee morale and pride at work.
