(1) The tent covers are constructed of fire-resistant materials, and
(2) Adequate ventilation is provided to maintain safe oxygen levels and avoid harmful build-up of combustion products and combustible gases.
(b) Torches. Torches may be used on aerial splicing platforms or in buckets enclosed by tents provided the tent material is constructed of fire-resistant material and the torch is turned off when not in actual use. Aerial tents shall be adequately ventilated while the torch is in operation.
(c) Soldering Devices. Electrical soldering devices shall be grounded. Defective soldering devices shall be immediately removed from service.
Exception:1: Soldering devices used exclusively for work on live circuits. Such devices shall be tested for current leakage not less than each 3 months.
Exception: 2: Soldering devices supplied through an isolating transformer with an ungrounded secondary of not over 50 volts.
Exception: 3: Soldering devices protected by a system of double insulation, or its equivalent. Where such a system is employed, the equipment shall be distinctively marked.
