  • Hi Temp Products is a privately owned, fully integrated, manufacturing company that has been producing high temperature, fire retardant, fire blanket materials since 1989.

    The head office and manufacturing facility are located in Edmonton, Alberta, Canada.Hi Temp has a subsidiary company, Comptex, Inc., located in La Conner, Washington, USA. Comptex is a weaver of fiberglass cloth and the exclusive supplier to Hi Temp of the proprietary fabric used in the production of Hi Temp materials including, but not limited to the material being used for Hi Temp Arc Suppression Blankets.

    Because of Hi Temps commitment to provide materials that increase the standard for safety of workers and their company as a whole, the company has once again, developed a new product, the Hi Temp Arc Suppression Blanket. This is used as a barrier for protection from the explosive and incendiary effects of electrical arcs and flashes. These hazardous electrical discharges can be caused by faults in cables, in cable splices and joints, and at transformer terminals, or they may be generated by the operation of switch gear, circuit breakers and lightning arrestors. The blanket can be used for worker protection in underground vaults, switchyards, and other locations where electrical equipment poses a risk of exposure to explosive electrical discharges.

    What is an Arc and an Arc Flash?The dictionary describes an electric arc as a luminous bridge formed in a gap between two electrodes.

    An Arc Flash occurs during a fault, or short circuit condition, which passes through this arc gap. The Arc Flash can be initiated through accidental contact, equipment which is underrated for the available short circuit current, contamination or tracking over insulated surfaces, deterioration or corrosion of equipment and, or parts, as well as other causes. An Arc Flash event can expel large amounts of deadly energy. The arc causes an ionization of the air, and arc flash temperatures can reach as high as 35,000 degrees Fahrenheit. This is hotter than the surface of the sun.

    AVAILABLE IN 4X5, 4X8 and Custom Sizes; Include grommets to easily keep the blanket in place Kevlar straps with buckle for mounting are sold separately ASTM F-2676 Blanket Test Approved Arc Suppression Blankets Water, UV, Solvent, Oil Resistant (one of its kind) Less than 30 seconds after flame time (shortest amongst arc flashes blankets tested; no off gas) Used as a barrier for protection from the explosive and incendiary effects of electrical arc flashes Ideal for use in underground vaults, switchyards and anywhere there is a potential of exposure to explosive electrical discharge. The Blanket must be mounted vertically between the worker and the potential fault. Adequate hanging distance from the potential fault is 6 inches (15cm). Do not wrap the potential fault. For maximum results fasten the blanket down using all attachment points to a permanent structure.

    Hi Temp Arc Suppression BlanketsElectrical discharges are unpredictable and as such using an Arc Suppression Blanket helps you to come through an arc flash accident with better results than had you not used it. The Arc Suppression Blanket is a secondary heat and pressure protection device for the worker. Proper personal protection equipment must be made available to the

    worker in accordance with NFPA 70E and OSHA 1910.269.

    Designation: F 2676 09Standard Test Method for Determining the Protective Performance of an

    Arc Protective Blanket for Electric Arc HazardsTEST REPORTS AVAILABLE UPON REQUEST

    The HI TEMP ARC SUPPRESSION BLANKET NOT ONLY MEET BUT HAS EXCEEDED 40% THE NEW ASTM F2676 STANDARDASTM Standard for Testing of Arc Blankets Arc suppression blankets are used in many electrical applications to protect workers who are stationed near energized electrical parts. While these blankets have been used for years, there have been no testing criteria for their evaluation. A new ASTM International standard will be used to determine the effectiveness of arc protective blankets in suppressing the combined effect of an arc flash and an arc blast. The new standard, ASTM F2676, Test Method for Determining the Protective Performance of an Arc Protective Blanket for Electric Arc Hazards, was developed by Subcommittee F18.65 on Wearing Apparel, part of ASTM International Committee F18 on Electrical Protective Equipment for Workers.

    This new standard gives companies the ability to evaluate blankets with a repeatable standard that can be done at many test labs using an electric arc and a high speed camera.

    HOW TEST IS BEING DONE:WITH BLANKET:

    40kA electric arc aimed at worker wearing approved arc flash safety equipment.The worker was completely protected. No permanent damage to the cloth mannequin was observed.

  • www.hitemp.ca

    WITHOUT BLANKET:

    40 kA electric arc aimed at worker wearing approved arc flash safety equipment. The blast burnt the entire body of the worker. The arm was thrown up and received what would have amounted to 2nd or 3rd degree burns. The safety mask was blown off and his face received major burns.Compliance Capability:Provides compliance with the following: OSHA 1910.269(1) (7)(i) and (ii) OSHA 1926.965(h)(1)*See page 20534 Federal Register Vol. 79, No. 70 dated April 11, 2014 for clarifications on the rules and regulations defining shields and/or other devices.

    CAUTION: Because of the unpredictability of electrical discharges, the Arc Suppression Blanket may not totally contain arcs and flashes, but only reduce or limit exposure and incendiary effects. The blankets can only give limited protection to workers because of the unpredictable nature of electrical faults. Proper risk assessment and installation can reduce the risk of injury from the blast and heat.

    WARNING Arc Protective Blankets are not designed for electrical insulating protection. Using the Arc Protective Blanket for electrical insulating protection can result in serious injury or death.

    NOTE: These products do not eliminate or reduce requirements for proper PPE for arc flash protection.
