2 Procedure No.: PA Page: 2 of PURPOSE To establish standard work practices and procedures at the BASF TOTAL Petrochemicals Limited Partnership Port Arthur, Texas ( Port Arthur ) site operated by BASF Corporation ( BASF ) for a ( PPE ) Program. 2. DEFINITIONS 2.1. Arc Flash Hazard A dangerous condition associated with the possible release of energy caused by an electric arc. An Arc Flash Hazard may exist when energized electrical conductors or circuit parts are exposed or when they are within equipment in guarded or enclosed condition, provided a person is interacting with the equipment in such a manner that could cause an electric arc. See Appendix F or G for examples of activities that could pose an Arc Flash Hazard. NOTE: Under normal operating conditions, enclosed energized equipment that has been properly installed and maintained is not likely to pose an Arc Flash Hazard Arc Flash Hazard Analysis A study investigation a worker s potential exposure to Incident Energy, conducted for the purpose of determination of the Arc Flash Protection Boundary and the appropriate protective clothing and equipment. BASF Technical guideline N-G-EI- 916 outlines methods, assumptions and deliverables Arc Rated or Arc Rating The value attributed to Flame Resistant (FR) material that describes its performance to exposure to an electrical arc discharge. The arc rating is expressed in cal/cm 2 (J/cm 2 ) and is derived from the determined value of the arc thermal performance value (ATPV) or energy of breakdown threshold (E BT ) 2.4. Boundary, Arc Flash Protection When an Arc Flash Hazard exists, an approach limit at a distance from a prospective arc source within which a person could receive a second degree burn if an electrical arc flash were to occur Boundary, Limited Approach An approach limit at a distance from exposed energized electrical conductors or circuit parts within which a shock hazard exists. See Appendix E, Approach Boundaries for Shock Protection.

3 Procedure No.: PA Page: 3 of DEFINITIONS cont d 2.6. Boundary, Restricted Approach An approach limit at a distance from an exposed energized electircal conductor or circuit part within which there is an increased risk of shock, due to electrical arc over combined with inadvertent movement, for personnel working in close proximity to the energized electrical conductor or circuit part. See Appendix E, Approach Boundaries for Shock Protection Contracted Employee For the purpose of this procedure, a contracted employee is an individual or group of individuals for whom BASF provides direct supervision in their day-to-day activities and direction as to how an activity is to be performed Contractors For the purpose of this procedure, a contractor is an individual or group of individuals who are retained to perform work by BASF but are not directly supervised by BASF employees. As used in this standard, contractor also means subcontractor Flame Resistant (FR) A term used to describe material that burns slowly or is self-extinguishing after removal of an external source of ignition. The FR garment must contain a label with information required by ASTM F1506 or ASTM F2733, including a statement that the garment meets the F1506 performance specifications, care instructions, fiber content and the Arc Rating. Garments must meet NFPA 2112 requirements as well Incident Energy The amount of energy impressed on a surface, a certain distance from the source, generated duing an electrical arc event. Incident Energy is expressed in calories or joules per centimeter squared (cal/cm 2 or J/cm 2 ) Personal Fall Arrest System A system used to arrest an employee falling from a working level. It consists of an anchorage point, connectors and a body harness, and may include a lanyard, deceleration device, lifeline, or suitable combination of these ( PPE ) Equipment worn to protect the eyes, face, head, hearing, lungs, body and extremities from injury and illness due to chemical exposure and physical hazards.
