Specific Chemical Substances/Tetraalkyl Lead Work Supervisor Text - Central Labor Accident Prevention Association, 6th Printing of the 14th Edition, Reiwa 6 (2024) Special Education, Skills Training, Examination, Certification, License, Certificate, Factory, Industry, Construction, Building, Cleaning, Painting, Paint, Coating, Welding How about for preparation, review, re-education, and checking important points? I obtained this two years ago, and I believe there haven't been any changes to the content since then. Because unauthorized reproduction and use of the content, images, etc. of this text are prohibited, I cannot post photos, but I have underlined in red the parts that were said to be on the exam. I was underlining in red while fighting off sleep, so some of the red lines are wavy and messy. Thank you for your consideration.
