What is the General Purpose and Locomotive Spark Arrester Guide?
The General Purpose and Locomotive Spark Arrester Guide is a compilation of information, lists, and illustrations of qualified GP&L spark arrester systems and engines – including their identifying markings, design, and assembly. The intent of the SAG is to provide field inspectors with adequate information to determine if an engine and exhaust system combination have been tested and qualified by the San Dimas Technology and Development Center (SDTDC) as meeting the Standard for spark arresting exhaust systems. The SAG is printed as two publications. This SAG covers General Position & Locomotive (GP&L) arresters, and the other SAG covers Multiposition Small Engine (MSE) arresters. In each publication, there is a section for each type of arrester with illustrations of spark arresters listed in alphabetical order by the manufacturer’s name, and lists of qualified and rated spark arresters of that type. Inspectors can use these sections to verify qualification status. Specific instructions
