OHST Exam Prep Series | Field2Compliance

Welcome to the Field2Compliance OHST Exam Prep Series, your guide to mastering the Occupational Health and Safety Technologist (OHST) exam.

In this video—Volume 2 of the Basic Hazards Study Guide—you’ll strengthen your understanding of physical hazards, engineering controls, fire prevention, and PPE alignment as they appear in Domain 3: Hazard Identification and Control of the BCSP OHST blueprint.

This lesson builds on the foundations introduced in Volume 1, moving from theory to practical field application and test interpretation. Drawing insight from OHST Exam Secrets by Mometrix and The Safety Professional’s Reference & Study Guide by Yates (not affiliated), you’ll learn how to distinguish between hazard categories, prioritize controls, and interpret exam-style phrasing for workplace safety scenarios.

Perfect for candidates preparing for the OHST, CHST, or ASP exam, this guide also benefits active safety professionals who want a structured, fast-paced review of OSHA standards, hazard control hierarchies, and NFPA fire safety concepts.

What You’ll Learn

• How to identify physical hazards such as pressurized systems, confined spaces, and elevated work
• Distinctions between engineering, administrative, and PPE controls
• Field examples of NFPA fire safety rules and grounding standards
• How to calculate fall clearance and scaffold height safety
• How to interpret OSHA terminology in multiple-choice questions
• Review of machine safety, excavation, and housekeeping hazards
• Integration of hazard recognition with field control applications

This video continues your preparation for Domain 3 and connects to Domain 2, reinforcing administrative safety management, inspections, and control verification methods.
