y appropriate fire protection systems and features are provided. See Regulatory Guide 1.189, Position 2.1.3 for additional guidance. During maintenance and modification activities, the staging and use combustible materials may be necessary. Procedures should establish strict controls on transient fire hazards such as wood, plastic, chemicals, filters, ion exchange resins, and other materials that are necessary to support plant operations, maintenance, modification, and refueling activities. Regulatory Guide 1.189, Position C.2.1.1 provides guidelines on controls of specific transient hazards. Temporary power cables used during maintenance outages are transient combustibles as well as potential ignition sources. Reviewers should verify that procedures adequately address fire protection for temporary electrical power supply and distribution. 5.3 Ignition source control practices Electrical equipment (permanent and temporary), hot work activities (e.g., open flame, welding, cutting and grinding), high temperature equipment and surfaces, heating equipment (permanent and temporary installation), reactive chemicals, static electricity, and smoking are all potential ignition sources. Design, installation, modification, maintenance, and operational procedures and practices should control potential ignition sources. Considerations include the following: a. Hot work involving open flame or spark producing activities should be controlled by a permitting process that provides assurance that the work activity is adequately reviewed by fire protection staff, the work area is adequately protected, and personnel trained to perform fire watch and suppress incipient fires are present during and after the work. b. Engineering design practices should provide assurance that electrical equipment is properly designed and installed in accordance with industry standards; heat generating equipment or equipment with hot surfaces is properly cooled or separated from combustible materials; and
