About this app

For the Industrial Engineer in Hazardous Materials Practical Exam, it is more important to review necessary content in a timely manner than to solve many problems.

Prepare for 11 subjects in one app: Handling of Class 4 Hazardous Materials, Handling of Class 1 and 6 Hazardous Materials, Handling of Class 2 and 5 Hazardous Materials, Handling of Class 3 Hazardous Materials, Understanding Standards for Hazardous Materials Transport and Handling Facilities, Establishing Hazardous Materials Safety Plans, Hazardous Materials Fire Prevention and Extinguishing Methods, Maintenance of Hazardous Materials Manufacturing Plants, Maintenance of Hazardous Materials Storage Facilities, Maintenance of Hazardous Materials Handling Facilities, and Hazardous Materials Administrative Processing. It includes self-produced questions and detailed explanations for each subject, and FSRS calculates the next review time based on your memory status for each question.
