![]() ![]() Rubber insulating gloves shall be rated for the voltage for which the gloves will be exposed. Workers must wear rubber insulating gloves with leather protectors and rubber insulating sleeves when there is a danger of hand and arm injury from electric shock due to contact with exposed energized electrical conductors or circuit parts. Shock Protection Workers must wear rubber insulating gloves with leather protectors when there is a danger of hand injury from electric shock. Inspect all PPE, including clothing, before use.Workers must be provided with hand and arm protection in accordance with NFPA 70E 130.7(C)(7)(a), (b), and (c) below.ġ30.7(C)(7)(a). The final third is ensuring that the PPE is maintained and cared for so that it does not create a greater risk for the employee. Remember, purchasing arc flash PPE and training employees to use it properly is only two-thirds of the equation. Oils, greases, and even mosquito repellent can have the same effect. Even though the tags may say arc flash rated, the material is now highly flammable. If fire resistant materials are washed with fabric softener, that residue remains behind. For instance, fabric softeners leave a flammable residue on clothing. Gloves must also be tested by an outside party every 6 months after they have been issued.Ĭaring for arc flash PPE can be trickier than one thinks. ![]() Even the tiniest pinhole is enough for electricity to find a path into and through the human body. Pinhole tests should be performed on arc flash gloves before every use, rolling up the cuff to seal the air inside and squeezing the glove to ensure no air escapes. To ensure that your arc flash PPE is in adequate condition, employees should inspect and care for the PPE per the manufacturer’s instructions. Arc flash PPE is only as good as its condition. While it might seem like a good idea to use the most protective arc flash PPE available, much of it is bulky and prevents the employee from performing fine manipulations that they may need to do and might even increase the employee’s risk of creating an arc flash. One part of the training these employees go through is to know what types of PPE they need for the work that they will do. Wearing arc flash PPE can mean the difference between life and death. Arc flashes occur far too frequently when an employee is testing to verify that equipment has been de-energized and find out far too late that it was not. This is particularly important when testing to verify that equipment has been de-energized. They must wear the proper PPE and establish arc flash boundaries to prevent others from being fatally injured. This is the main reason why employees need to understand that only trained and qualified personnel can perform work on energized electrical equipment, and they must take appropriate precautions. Of those who survive, many are permanently injured or impaired as a result. The arc flash itself comes from the sudden, explosive release of energy from a fault in a phase to ground, or between 2 phases.Īrc flash incidents are severe and cost many employees their lives. Conditions such as dust build-up and corrosion also cause arc flashes. Interaction with the equipment can cause electric arcs, too, such as when electrical systems are accidentally contacted, when tools are dropped, or when improper work procedures are followed. An arc flash can occur when energized electrical conductors or circuit parts are exposed, or when they are within equipment in a guarded or closed condition. What produces temperatures four times greater than the surface of the sun, instantly vaporizes metal, and can throw a grown man across a room like a rag doll? An arc flash.Īrc flash incidents are severe, and do not discriminate between trained and untrained employees. ![]() Industrial Hygiene & Ergonomics TrainingĪrc Flash PPE – Personal Protective Equipment.Forklift & Heavy Equipment Operator Safety Training.Mobile Testing and Respirator Fit Testing.Amerisafe Center for Safety Leadership Online. ![]()
