When selecting an 8 cal or 12 cal arc flash kit. Is the balaclava required as to the standards or is the addition of it just for more personal choice providing more protection? Terry |

A balaclava is required by 70E. Table method requires it over 4 cal, calculation method would require it over 1.2 cal. I would select a 12 cal in that case, so as not to limit yourself to only 8 cal with your equipment. |

Thank you So a kit that is provided "without" the balaclava is not in compliance unless the end user has their own balaclava on hand. Is that correct? |

There is an additional wrinkle to this. OSHA 1910.269 for outdoor overhead equipment recommends balaclava is not required until 9 cal/cm2 or higher. There is a TIA that corrects the discrepancy in annex H as far as 1.2-4 cal/cm2 goes. |

So it looks like there might be grey area in the regs there. |

If you are following 70E you should be using a balaclava for anything greater than 1.2 cal/cm2. If you are not following 70E, as Paul mentioned, you can leave the balaclava out until you get to 9 cal. If there is a chance that an arc flash could occur when the worker is not perfectly square to the flash, then a balaclava should be used. Wouldn't really want to take something greater than 1.2 cal to the back of the head with no protection. |
