4.11 GAS FREE WORK PERMIT (GFWP) – A permit, resulting from approval by an authorized person under the application of a defined documented management work process, stating that work involving potential ignition sources may be performed in a hazardous (classified) location by ensuring that the atmosphere is free of ignitable concentrations of flammable gases or vapors. Note 1 to entry: Refer to NFPA 51B which provides provisions to prevent loss of life and property from fire or explosion as a result of any work involving burning, welding, or similar operations that is capable of initiating fires or explosions.

6 Portable/Personal Electronic Products (PEPs) 6.1 General 6.1.1 PEPs shall meet the following criteria: a) No available NRTL certified types of portable/personal electronic products suitable for the area classification and capable of performing the intended function. Differences in manufacturer/brand or software feature do not constitute a lack of availability. b) The equipment complies with the applicable equipment requirements to ensure general product safety. Examples of general product safety requirements are protection from fire, electrical shock, chemical, mechanical hazards, etc. NOTE: Some standards used to demonstrate compliance with general product safety are UL 62368-1, UL 60950-1, UL 61010-1, UL 60601 series, UL 1642 etc. c) Equipment used in accordance with manufacturer’s instructions. d) Unless permitted by the manufacturer’s instruction, the configuration of the product may not be changed for the purpose of meeting a PEP definition. NOTE: An example of a non-permitted configuration change would be a substitution of cells or batteries other than those identified in the manufacturer’s instruction. e) No provisions for forced ventilation. f) No sparks visible in normal operation. g) No excessive temperatures (see 4.10) in normal operation. h) No motors unless it can be demonstrated the motor incorporates non-arcing technology (construction that does not incorporate brushes).UL 121203-2021 pdf download.
