PROGRAM INFORMATION BULLETIN NO. P07-28 FROM: KEVIN G. STRICKLIN  Administrator for Coal Mine Safety and Health SUBJECT: Updated Test Questions for Certifying Individuals to Perform Dust Sampling and Maintenance and Calibration of Approved Sampling Equipment (Amended) Who needs this information? Mine Safety and Health Administration (MSHA) enforcement personnel, coal operators, miners' representatives, contractors, and special interest groups. Why is MSHA issuing this bulletin? This Program Information Bulletin (PIB) and associated test questions amends PIB 07-23 which omitted laboratory performance criteria for the respirable dust sampling test and contained errata in the test questions. This PIB informs the mining community of the updated pool of test questions for certifying individuals to perform dust sampling and maintaining and calibrating approved sampling equipment. Questions have been updated to include a more recently approved coal mine respirable dust sampling unit, remove units no longer approved, and improve coverage of the different aspects of the associated regulations. The questions related to maintenance and calibration of the approved respirable dust sampling unit have been updated to include new technology and improved coverage of the associated regulations. What is the background for this PIB? Title 30 C.F.R. parts 70, 71, and 90 require respirable dust sampling and maintenance and calibration of approved sampling devices to be performed by a certified person. Current regulations require an individual to pass the MSHA examination on sampling of respirable coal mine dust or the MSHA examination on maintenance and calibration procedures for respirable dust sampling equipment to become certified in either function. What is the effect of updating the certification examination(s)? The updated test questions will help those seeking to be certified to become familiar with the regulatory sampling requirements, the sampling and calibration equipment required to be used, and the procedures to be used for maintenance and calibration of this equipment. It will also help instructors better evaluate the knowledge, skills, and abilities of an individual seeking to perform the duties and responsibilities of a certified person and ensure more uniform administration of certification examinations. How will the examination(s) be administered? If the individual seeking to be certified for respirable dust sampling attends a class of instruction administered by MSHA, the certification examination will involve answering at least 25 questions, completing the Dust Data Card based on the scenario provided, and satisfactory completion of the performance criteria outlined below. The examination will consist of at least 5 questions, selected by the instructor, from each of the 5 sections of the pool of questions. In the event the individual elects to only take the exam, the certification examination will involve answering all 123 questions included in the 5 sections, completion of the Dust Data Card, and satisfactory completion of the performance criteria outlined below. Performance Criteria. Each applicant will:
b. Examine the cyclone(s) for cleanliness. c. Examine the inner surface of the cyclone(s) for scoring. d. Examine external tubing for leaks, cleanliness, and proper length. e. Examine the clamping and positioning of the cyclone, vortex finder, and cassette to insure they are rigid in alignment, and firmly in contact. 3. Correctly place the MSA Escort ELF® and any other approved sampling device on another class member or on the instructor. The minimum passing score for each examination (including lab or performance criteria) will be 80 percent. Who are the contact persons for this bulletin?
