Among other hazards, the risk of impact injury is extremely high in the oil and gas industry due to work in extreme environments. Workers may be exposed to crush and pinch impacts daily, making it crucial to have high-performance hand protection, especially for the knuckles, fingers and thumbs.
The NEW ANSI/ISEA 138-2019 Impact Resistant Glove Standard was developed to better classify the impact resistance of gloves, making it easier than ever to choose the right impact glove for any application. The new standard considers the minimum performance, classification and labeling requirements for material protecting the fingers and knuckles from impact.
Understanding ANSI/ISEA 138-2019 Testing
ANSI/ISEA 138-2019 outlines three levels of impact protection. Each level is determined by how effectively each glove can disperse impactful force applied during testing. This impactful force is created by dropping a 2.5-kilogram mass onto each glove with an impact energy of 5 joules. This process is repeated ten times on the fingers and eight times on the knuckles. The glove’s impact level will then be determined based on the Mean Transmitted Force (MTF) recorded.
It is important to note that the MTF of the finger region is treated separately from that of the knuckle region, so the lower MTF of the two regions will be used to classify the glove’s impact resistance as a whole.
Performance Level Classification
The MTF is measured in kilonewtons which means the lower the kilonewton measurement, the better the glove is at dispersing the impact energy along the surface of the protective material. This helps to prevent the impact energy from transmitting directly to the hand and results in a higher level of impact protection.
Level 1 recordings provide a higher kilonewton measurement which results in lower impact protection. Conversely, a Level 3 performance rating results in a lower kilonewton of transmitted force to the hand, which results in better impact protection.
EN 388 vs ANSI/ISEA 138
Previous to ANSI/ISEA 138-2019, the EN 388 Standard was the only measurement of impact protection that could be referenced. The European standard impact test is based on the EN13594:2015 Standard for protective gloves for motorcycle riders. The test method is similar, but only tests the knuckle impact (excluding the fingers). The EN 388 Standard classifies impact protection with a letter representation: P represents Pass, F represents Fail, and X represents Not Tested. If the average transmitted force is less than or equal to 7kN, then the gloves will receive a Level 1 P Pass rating. If the average transmitted force is higher than 9kN, then the gloves will receive a Level 0 F Fail rating.
The new ANSI/ISEA 138-2019 standard breaks down this letter representation into a numerical range of mean transmitted forces. This allows different impact-resistant applications to precisely match up to the correct numerical value or level needed for the job.
Third-Party Testing
The ANSI/ISEA 138- 2019 standard shall be tested by independent IOS/IEC 17025 testing and calibration laboratories. This ensures all information is accurate and standardized. Before this, manufacturers had free reign on impact-resistant claims, leading to unjust injury.
The Need for Impact Protection
In high-risk environments such as oil and gas, there is a greater need and desire for higher impact protection such as ANSI level 3. The current market has limited options of gloves that meet these requirements. The need for impact protection should never lead to a sacrifice of other required benefits such as dexterity, comfort and longevity. The new ANSI/ISEA 138 testing standard makes it easier to trust and understand the protection workers are getting with available PPE.
