What the STSC Exam Tests

The BCSP STSC exam focuses heavily on OSHA 29 CFR Part 1926, the federal standard governing construction safety. Questions are practical and applied — you need to recognize hazardous conditions, know the correct control measure, and identify the applicable OSHA subpart.

OSHA Subpart C – General Safety and Health Provisions

This foundational subpart covers employer obligations, safety programs, accident prevention responsibilities, and required recordkeeping. Expect questions on competent person requirements and employer duty to protect workers from recognized hazards.

OSHA Subpart E – Personal Protective Equipment

Hard hat classes, eye and face protection selection criteria, fall protection harness inspection, and foot protection requirements are all testable. You must know when each type of PPE is required and how to verify it meets ANSI standards.

OSHA Subpart M – Fall Protection

The 6-foot trigger height for fall protection, guardrail specifications, safety net requirements, and personal fall arrest system (PFAS) components are heavily tested. Know the difference between fall restraint and fall arrest systems and when each applies.

OSHA Subpart P – Excavations

Trench and excavation safety questions cover soil classification (Types A, B, C), sloping and benching requirements, shoring system design, trench shield use, and required inspections before each shift. The competent person role in excavation safety is frequently tested.

OSHA Subpart K – Electrical Safety

Jobsite electrical questions address ground fault circuit interrupter (GFCI) requirements, assured equipment grounding conductor programs (AEGCP), overhead power line clearances, and lockout/tagout application during construction activities.

Hazard Communication and Tool Safety

GHS labeling elements, SDS section contents, and employer training requirements under HazCom 2012 are tested. Hand and power tool questions focus on guarding requirements, grounding, and safe work practices that prevent struck-by and caught-in injuries.

Incident Investigation and Safety Meetings

The STSC exam includes questions on root cause analysis techniques, near-miss reporting, corrective action documentation, and how to run an effective toolbox talk or safety meeting to change worker behavior on the jobsite.
