Cal/cm² & ATPV How They Work to Keep Us Safe


How often have you heard someone say, “I need an 8 cal shirt.” Or, “My clothing needs a minimum of an 8 cal rating.” Or even, “My blast suit is 40 calories.” These common statements are the reason the NFPA 70E committee changed their terminology from hazard risk category (HRC) levels to personal protection equipment (PPE) levels in the 2015 revision of this standard. People unintentionally used the calorie rating of an HRC as a protection level of PPE when instead it is a way of determining the potential level of exposure during an arc flash event which then allows us to select the proper PPE which will then protect the worker in a worst case scenario involving an arc flash.
When an arc flash occurs, among other things, there is a release of incident energy. Calories/cm² (Cal/cm²) is a unit we use to measure this incident energy. You may also hear this energy measured in Joules/CM² but Cal/cm² is more common. An arc flash duration is measured in milliseconds meaning arc flashes typically last less than a second. The exposure to flame is very short but the absorption of incident energy by the body during this event can have drastic consequences leading to sever burns.
1 Cal/cm² of incident energy will raise 1 gram of water 1 degree Celsius. This is important to us because the human adult body contains roughly 57-60% water. When we are exposed to incident energy the water in our tissues heats up and we can incur a burn even if our clothing is not ignited. The onset of second degree burn can occur at 1.2 Cal/cm². Many people use the analogy of 1.2 Cal/cm² being equal to holding a finger over a flame for one second.
Incident energy affects the human body differently than normal thermal events. As we know we measure burn degree by depth of burn through the skin. The deeper the burn is the higher the degree the burn is given. With incident energy exposure the water in our tissues become superheated and burn depth occurs very quickly. To avoid this we need to know what the potential incident energy level is during a particular arc flash event and label that measurement in Cal/cm². Once this assessment is complete the information is shown on a label which is then attached to the equipment in a visible location. When the level of the hazard is known we can proceed with selecting a garment that will help protect the employee.
When looking at an arc rated flame resistant garment the rating you should see included on a label, as required by the American Society for Testing and Materials (ASTM) standard F1506, is the arc thermal performance value (ATPV) of the fabric. As an alternative some fabric manufacturer’s report an EBT or energy breakthrough value for the garment. EBT is the point at which the fabric breaks open while ATPV is an insulating value. The ATPV number tells us the point at which 1.2 Cal/cm² of incident energy is transferred through the fabric and, as we discussed earlier, is the point at which a 2nd degree burn can be expected. Either number can be reported but the lower of the two numbers must be used. For instance if breakthrough occurs before a thermal value can be given then the EBT number must be used.
Understand that the garment being selected is not arc rated. The fabric the garment is made from is arc rated.. Flame resistant fabric intended to be used for arc flash hazard protection must be tested using the ASTM F1959 test standard. The test requires swatches of fabric to be exposed to different levels of incident energy. Remember this test rates FR fabric and it is not a pass or fail test. After testing is complete the manufacture then reports out either an ATPV or EBT number for that fabric.
The FR arc rated fabric can now be used to manufacture different types of garments such as coveralls, shirts, pants etc. If you have ever wonder how a mesh vest gets an ATPV or EBT rating it’s because the fabric used to make the vest actually has the rating. Common sense should tell us that a mesh vest is not going to protect us from burns in an arc flash incident. However, when worn over an arc rated shirt or coat, the vest rating tells us that the material the vest was made from will not melt, drip, or add to the flammability of the arc rated shirt or coat in an arc flash incident. This same common sense should be used when looking at short sleeve shirts. These products are great as an added safety feature but should never be worn with the expectation of protecting the entire upper body.
So now we understand what Cal/cm² means and what ATPV/EBT means. Cal/cm² is a rating for what level of incident energy we might expect should an arc flash occur and is directly related to equipment. ATPV and EBT are values given to FR fabrics that tell us, when exposed to incident energy, how that fabric will perform and what level of protection we can expect in an arc flash incident. Once again Cal/cm² is for equipment and incident energy. ATPV and EBT are values given to fabric. The Cal/cm² number is displayed on the equipment and the ATPV or EBT value is displayed on the garment label. The garment must have an ATPV or EBT value that is at least equal to or greater than the Cal/cm² number.
To ensure a successful arc rated garment program the employer should take the time to train employees on these two key values. Because many work environments allow for employees to work on their own, they need to understand what level of protection they need to perform their tasks safely. Also just because several pieces of equipment are on the same electrical feed does not mean they have the same level of hazard potential. Factors such as distance and resistance from the substation will affect the level of hazard even if they are the same type of equipment. Employees need to know what the label on the equipment means and what the Cal/cm² value means. They must then know to compare that number to the ATPV or EBT value and be sure that this value is greater or equal the incident energy potential to ensure the mitigation of serious injury.
If the ATPV or EBT value is not equal to or greater than the Cal/cm² then the employee must be able to recognize this and take the proper step to increase their protection level. This could include adding another layer of arc rated garments such as a coverall but know that in order to ensure a protection level through layering, all the fabrics used for a layering solution must have been tested together using the ASTM F1959 tests method to achieve a true ATPV or EBT value. You cannot use an addition method for determining layer protection. In other words 8 ATPV over 8 ATPV does mean 16 ATPV. Different fabrics react differently together resulting in various ATPV values so testing must be done to ensure a safe system.

Flame Resistant (FR) and Arc rated (AR) Clothing

Flame Resistant (FR) and Arc rated (AR) Clothing, these 2 terminologies are very often being heard about in the PPE industry today. As per NFPA70E, what was earlier referred to as Flame resistant (FR) clothing is now called Arc Rated (AR) clothing.
A simple note defines the difference between these 2 terms – ALL clothing with an Arc rating (AR) is Flame Resistant (FR), but not all FR clothing has an Arc rating. AR clothing are designed to protect the wearer against Arc Flash. The level of the AR clothing is defined by how much heat energy the fabric is able to block.
Flame resistant clothing is known to provide two-fold protection:
  • Against Flame:
FR clothing is worn to guard against flame during an accidental fire situation. Protective clothing is put through Flame Test, as per various standards like ISO 15025, ASTM D6413 etc. to determine the protection level of material under controlled conditions.
  • Insulates the wearer against heat hazards:
Insulation against heat hazards is the second function of FR clothing. Flame resistant clothing provides the wearer protection from various heat related hazards like radiant heat, convective heat, contact heat etc. and can lessen the impact on the area directly affected by the accident.
To be an Arc rated (AR) fabric, it must first be a FR fabric. Depending upon the weave construction, blend and weight of the fabric, it may offer different levels of arc protection.
According to the various arc rating standards like ASTM F1959, IEC / EN 61482-1-1 clothing needs to be FR before it can even be tested to determine its Arc rating.
How an Arc Rated fabric (AR) is tested?
For the ASTM F1959, IEC / EN 61482-1-1 testing, 21 samples of textile material are subjected to an arc flash and heat transfer is measured through the fabric using sensors. Stoll curve model predicts whether or not a 2nd degree burn would result by use of the textile material and also calculates the energy likely to cause the onset of 2nd degree burns through the fabric, 50% of the times the material is tested. This energy level determines the Arc rating of the textile material. This energy is expressed in calories per centimeter square (cal/cm²). The arc rating can be reported as ATPV (Arc Thermal Performance Value) or EBT (Energy Breakopen Threshold). ATPV and EBT may both be evaluated in the same test, but the first point to be reached is reported as the arc rating.

Why one size of PPE does not fit all

Personal protective equipment (PPE), such as arc rated FR clothing, is a critically important part of every electrical safety program. It should be used as the last line of defense, meaning it helps protect when all other preventative measures have failed. In fact, the hierarchy of controls puts eliminating the hazard as the most effective way to protect workers. However, in many cases engineering can reduce but not eliminate the hazard. Energized work poses an arc flash risk, and there’s really no such thing as a “small” arc if you are the person standing in front of it. Virtually all arcs pose an ignition risk to flammable clothing.
Since FR clothing is not meant to be used as a primary protection method, it’s fallacy to believe that one size of PPE fits all types of employees. A successful safety program will address each situation independently and treat individuals in the safety program uniquely depending on their job function and exposure to a hazard. Being safe is just as much about the employees themselves and employees buying in to the program to make safety a priority and not something their company tells them they have to think about.
If it’s determined that PPE is needed, companies need to address what type of PPE is best and offers the most protection. For electricians, choosing rubber gloves and PPE based on the proper size and voltage ratings can prevent accidents by permitting the worker the proper dexterity needed to perform electrical tasks.
To make a program easy and more manageable, some companies may only want to buy XL PPE. However, this fails to recognize that workers come in many shapes and sizes. For example, if sleeves are too long, electricians may roll their sleeves up and expose his or her wrists and hands to injury. Sleeves need to be worn buttoned and tight-fitting on the arm.
Likewise, wearing garments that are either underrated or too bulky can put electricians in harm’s way. Many safety managers say they need PPE Category 2 protection but this level of protection is rather broad. Wearing minimum PPE Category 2 apparel when the incident energies can exceed 20 or 30 cal/cm2 could cause severe third degree burns that may lead to infection or death, if the electrician survives the initial incident. At the other extreme, using a PPE Category 4 suit and hood when a PPE Category 2 is recommended could make movement and visibility unnecessarily difficult for the electrician. This may end up creating a dangerous situation rather than protecting against one.
Clearly, the one-size-fits-all approach is not appropriate for workers needing PPE. Choosing garments that are the right sizes for each worker ensures that protective clothing is worn properly and will provide the optimum amount of safety.
Don't let choosing the best PPE for your situation become a daunting task,partner with a supplier that can help guide you through the process! Drotex is your best choice.

Four NFPA 2112 updates that could impact your FR program

Back in the fall, NFPA 2112: Standard on Flame-Resistant Clothing for Protection of Industrial Personnel Against Short-Duration Thermal Exposures from Fire saw new changes implemented for the 2018 edition, which went into effect on September 6, 2017. The 2018 edition is a barometer for the safety industry as a whole – impacting suppliers and manufacturers down to end users. If you are investing in flash fire PPE in 2018, we outline four significant changes you should be aware of as you specify your garments and implement relevant protocols.
Updated Terminology:
Right off the bat, you’ll notice a shift from the use of the word “flash fire” to “short-duration thermal exposures from fire.” This terminology was developed in the last version of NFPA 2113 and is now utilized throughout the 2018 edition of NFPA 2112, including in the title. If you are looking to protect workers from flash fire incidents, NFPA 2112 is still the applicable standard to reference.
Outerwear Parameters:
Cold weather insulation fabrics were covered under a Tentative Interim Amendment (TIA) in the last version of NFPA 2112. This TIA is now incorporated into the 2018 version of NPFA 2112. The requirement includes a modified flammability testing protocol for insulation material, both as received and after 100IL testing. Thermal shrinkage will not be measured for insulation materials, nor will the ASTM F1930 testing apply.
Even with the outerwear expansion, NFPA 2112 will not cover flash fire-rated rainwear. The appropriate standard to reference will remain ASTM F2733.
New Product Requirements for Hoods, Shrouds, Balaclavas and Gloves:
The 2018 version of NFPA 2112 now addresses other PPE items beyond typical garments. The new requirements cover hoods, shrouds and balaclavas, which are defined as items to protect the head and/or neck. Gloves are also a new PPE item, specifically designed to protect the hands and wrist. These items do not currently have a thermal manikin type test; however, a majority of their testing requirements is similar to standard body fabrics.
Refined Testing Requirements:
Due to concerns on variability of the ASTM F1930 test method, additional testing requirements have been created. Further calibration language has been added, which now requires the laboratory to verify sensor response to additional heat fluxes prior to testing. An additional requirement to test standard reference garments has been included as well. When tested, these standard reference garments shall attain results within a pre-determined range for testing data to be valid.
Because of the significant changes in NFPA 2112, delays in certification testing are expected. All component and PPE manufacturers must recertify products to the new 2018 version of NFPA 2112. PPE manufacturers have until September 6, 2018, to certify their products to the new method. After that date, they will not be allowed to label products as compliant unless they meet the 2018 method.
It is important to understand how the 2018 edition of NFPA 2112 impacts your FR program in the coming months and years, and our team can help you analyze the impacts. Contact Drotex today to learn more.

How to avoid Static Electricity Shocks in Cold, Dry Weather?

The weather of winter in some areas is so dry that everything one touch gives a shock. What can we do to avoid constant static electricity problems in the house?

In the winter it feels like everything you touch shocks you,and first thing in the morning it can be quite a jolt to the system.Luckily,there are a few things you can do to minimize all of that.
Common Culprits of Static Shock

One of the easiest ways to avoid static shock is to pay attention to what you're wearing and what kind of fabrics make up the furniture in your house. For example, Electrostatics.net notes that rubber-soled shoes are great insulators, and will build up a lot of static in your body when combined with a wool or nylon carpet. Instead, try walking around in leather soled shoes, or cotton socks instead of wool socks. Leather soled shoes are also great for grocery shopping, since shopping carts can often cause lots of static electricity.
Similarly, wool sweaters are common offenders, especially in the dry winter (when you usually wear them). If you sit in a chair made out of the right fabric, you'll build up quite a bit of static. Again, cotton is going to be much more friendly, so try wearing cotton clothes when you want to avoid nasty shocks. Certain furniture covers or antistatic sprays can help alleviate this problem, too.
You may have also noticed that often, when you get out of your car, you get a shock when you touch the door. You might have even heard that touching the door frame as you get out of the car can help, and that's true. Make sure you start holding the metal frame before you get out of the car, and you keep touching it until you're out of the seat completely. If you forget to do this, you can also touch the car door with your keys. Since the electricity will discharge through them, you won't feel a shock.
De-Static Your Home with a Humidifier

The tips above will work when you're out and about, but when you're in your own home, there are a few other things that ensure you can wear those rubber-soled shoes and wool sweaters when you want to. A humidifier can make the air a bit less dry, and thus lower the possibility of you getting shocks at home. Generally, you want to keep it above 30% relative humidity, though 40% or 50% would be even better. We've talked before about picking the perfect humidifier for your home (which has many other benefits), and if you want to keep an eye on the relative humidity, you can pick up a cheap hydrometer from most garden stores. It'll really make a world of difference.
That may seem long-winded for a discussion of static shocks, but when you're struggling through those harse winter months, those shocks start getting really irritating day in and day out, and just a few simple tricks can help you eliminate that household annoyance.

4 steps to specify reliable flame resistant workwear

Every day, workers in electrical maintenance,utility, oil and gas, petrochemical and steel
industries work in hazardous environments.Unexpected and highly dangerous arc flash and flash fire events can occur without warningand may result in severe or fatal burn injuries.Thus,we need reliable flame resistant workwear to protect workers from being injured.Here are 4 steps to specify reliable FR workwear.
1.Research environmental risks
Gain a deep understanding of your work environment and thespecific issues that impact worker safety. Begin with identifyingthe risks at hand, such as arc flash risks versus flash fires, as theapparel needs are different.The standards for which you are specifying fabrics must apply toyour individual work environment. For example, FR fabrics that meet PPE Category 2 are irrelevant in the oil and gas industries, as the arc rating standard addresses electrical arc flash, not flash fire hazards.External factors, such as weather, should also be considered. The fabric and fabric system needs in diverse climates can be very different. Cold, northern climates may need insulated products for their daily work where southern climates may dictate a single layer. 
2.Evaluate fabric options
When evaluating viable options for AR/FR fabric, don’t settle for minimum compliance. Instead, know the exact rating of each fabric. Also, consider a wear trial to assess comfort and wearability so you know firsthand that employees will be able to work effectively and comfortably.
3.Understand the fabric's performance
There is a vast disparity between products that comply with NFPA 2112 and NFPA 70E. Compliance is a starting point, then individual fabric performance should be evaluated to help ensure you are adequately protecting workers. 
4.Specify fabric by brand name
Brand name FR textiles carry a trusted reputation because they have been market proven to protect workers. Brand name reputations also help you know exactly what you are purchasing. Not all FR fabrics or constructions — such as 88/12 fiber blends — are the same. There are significant differences in how similar fabrics with similar fiber constructions perform. Rely on proven brand name reputations to gauge the effectiveness of FR performance, backed up with third-party certification.

Our CFR265 Pyrovatex has been certified by BTTG

Not long ago,Our department of development invented a new item. 100% cotton flame retardant antistatic woven fabric which is treated by Pyrovatex created by Huntsman.
This fabric uses ringing spun yarn which quality is very good as greige cloth.In the dyeing process,we use vat dyestuff to make the fabric color fastness have higher grade.For the FR performance,we import Pyrovatex flame retardants which is produced by Huntsman. Compared with Proban or THPC,fabric treated by Pyrovatex or CP has better color fastness and handfeel more comfortable. The fabric can pass EN11611,EN11612,EN14116,EN61482-1-2,EN1149,NFPA2112,etc.
This time when we complete the new product,we sent a piece of sample to BTTG to test the flame retardant performance and antistatic feature. BTTG is a wolrd famous organization focused on test and certification of textiles.
After half a month,good news comes. The 100% cotton CP flame retardant fabric has successfully passed EN11612 and EN1149-3 standard. It proves that our FR fabric quality is certified by European Union Standard and can be widely used as FR clothing for workers in various industries.
As a leading supplier of flame retardant fabrics,Xinxiang Zhuocheng Special Textile Co., Ltd will continue to develop high quality products and provide better protection for global workers!

How does flame resistant clothing work and what fields is it used?

1.How does flame resistant clothing work?

A piece of clothing that is fire resistant is made of material that when in contact with fire will self extinguish and prevent the worker from suffering injuries. It is used as a safety precaution for people who work in hazardous industries.

2.What's the application of flame resistant clothing?

When you hear of Flame Resistant Clothing you may think that it’s just for firefighters or someone who works in extremely hot environments. The truth is that many hazardous work environments require their workers to wear FRC. Electrical equipment is prone to catching fire as well as the chemicals in a refinery or even when processing paper and paint. You will find many electricians, pharmaceutical and factory employees use this type of clothing.

We are professional flame resistant clothing and fabric manufacturer.Any information,please feel free to contact us!

EN 20471 HIGH VISIBILITY CLOTHING - TEST METHODS AND REQUIREMENTS

The norm for High Visibility,EN 471, is one of the most widely known and used norms under the PPE directive.
In June 2013,The Official Journal of the European Union published the new standard EN ISO 20471:2013.
This harmonized standard has replaced the former standard
EN471:2004+A1:2007.Starting October 2013,therefore,all High Visibility products have to be CE marked and certified to ISO EN 20471.
Why do we need a new title?
The title of the new standard <<High visibility clothing - Test methods and requirements>> removes the previous distinction between professional and non-professional use and the new standard is concerned with risk assessment and risk analysis for the selection of the correct visibility clothing for high risk scenarios.

The standard specifies the requirements for high visibility clothing "which is capable of visually signaling the user's presence".
The new standard has broadened the usage base and distinction between different types of risk situations has been made.
The defined risk situations will be the basis for which norm is applicable for the user. ISO EN 20471 is applicable to high-risk situations.
For more information about EN 20471,please feel free to contact us.

Tips to choose best fabric for ppe welding clothing


Currently the fabrics used for making protective suits in basic/plasma welding companies and cutting processes, are generally weighty heavy items, either 100% cotton or FR fabrics. Depending on the intensity of the welding or cutting operations, protective clothing of these groups has a low durability. Moreover, in these cases skin or leather are also used and heavy weight (over 700 gr/m2), being a very uncomfortable solution by weight, low breathability and for its lack of flexibility.
Although the more effective level of tissues protection and the comfort problems previously mentioned, the leather has other drawbacks such as the fact that it cannot be washed or the veto in some countries for environmental reasons due to waste subsequent to manufacture and disposal.
After over two years of study and with the conviction that the Standard EN ISO 11611 does not reflect the real risk and hazard that the activity requires, Drotex has developed a new range of products under the name FRCOTTON, fabric weight of which is about 400 gr/m2, supporting 30 seconds of continuous welding after 25 washes, as you can see in our catalogue on our website.
The conclusion of this range of fabrics is to get the same or better protection of current solutions with more textile concept, i.e. without reducing the protection, having better values of comfort and durability.
