![]() Proper storage means that gloves must not be folded and need to be kept out of excessive heat, sunlight, humidity, ozone, and any chemical or substance that could damage the rubber.įor additional information on the use of insulating gloves and sleeves, see ASTM F496, Standard Specification for In-Service Care of Insulating Gloves and Sleeves, and ASTM F1236-96, Standard Guide for Visual Inspection of Electrical Protective Rubber Products. ![]() To ensure worker safety and the integrity of the gloves and sleeves, insulating gloves need to be worn along with protector gloves (such as leather), and both insulating gloves and sleeves need to be stored properly when not in use. The tape is made from a durable vinyl material that can withstand environmental factors. Requiring a single layer of arc-rated PPE, workers need the following clothing: Required Clothing: Long Sleeve Shirt (or Jacket) and Pants or AR Coverall with minimum arc rating of 4 cal/cm 2. PPE CAT 1 represents the lowest level in which Arc Rated PPE s required. Workshop Notes: Arc Flash Analysis Slide 30 Updates on NDC Arc Flash Maximum Power Method Removed 125 kVA Exception (An Arc Flash Hazard Analysis may not be necessary for some three-phase systems rated less than 240 Volts Added DC Arc Flash Boundaries table. The tape features the message 'Arc Flash Boundary' printed in bold white letters on a red background. PPE Category 1: Minimum Arc Rating 4 cal/cm2. ©1996-2017 ETAP/Operation Technology, Inc. ![]() (See ASTM F496, Standard Specification for In-Service Care of Insulating Gloves and Sleeves for some appropriate test methods.) When gloves and sleeves are used regularly, best practice is to test as frequently as monthly. The Arc Flash Boundary tape is a high-quality messaging tape designed to promote safety in areas where there is a risk of electrical arc flash. In addition, the gloves and sleeves must be electrically tested at regular intervals of not more than 6 months for gloves and 12 months for sleeves. Insulating equipment failing to pass inspection must be removed from service and may not be used by workers. Insulating equipment may not be used if any of the following defects are present: holes, tears, punctures or cuts, ozone cutting or ozone checking, embedded foreign objects, texture changes, including swelling, softening, hardening, or becoming sticky or inelastic, and any other defect that damages the insulating properties. Best practice is to inspect PPE and air test the gloves and sleeves before each use. Simply put, the arc flash boundary is the distance at which an electrical arc can flash/expand outward, which may endanger employees working on electrical equipment. They must also be visually inspected and gloves need to be air tested for any possible defects (for example, cuts, holes, tears, embedded objects, changes in texture) before each day's use and whenever there is a reason to believe they may have been damaged. Gloves and sleeves must be electrically tested before being issued for use. arc flash procedures need to be clearly defined and the working personnel shall be trained on arc flash policy and what is the danger of arc flash and shall be clearly instructed on the usage of arc flash PPE.See: 1910.269(l)(2)(i) and 1910.269(l)(3) on insulating gloves and sleevesĪlso see: 1910.137 on rubber insulating equipment Arc flash assessment requirements are clearly mentioned in NFPA 70e all hazard flash safety guidelines including arc flash distance, arc flash PPE need to be mentioned in the arc flash warning labels. ![]() Arc flash hazard study also known as arc flash risk assessment is performed to identify and mitigate the arc flash hazards or arc flash risks available in the system and ensure the safety of the working personnel with proper arc flash safety procedure.Īrc flash policy for study demands that arc flash survey needs to be carried out before building the real time model for arc flash assessment. Arc flash analysis is a combination of electrical study with ref to the safety guidelines. What is arc flash analysis? is the first question that raises in every safety concerns mind.
