01Safety Program Management and OSHA Regulatory Compliance
The NCCER CSSS exam tests whether you can build and run a construction safety program that satisfies OSHA standards and can explain how inspections, citations, and recordkeeping work. A workable program includes written policy, assigned responsibility, hazard assessment, training, inspections, incident review, emergency planning, and corrective-action tracking.
385 words, about 2 min02Hazard Identification, Assessment, and Control
This domain tests whether you can recognize unsafe conditions and behaviors before harm occurs, rank risk, and choose controls that reduce exposure rather than merely satisfy paperwork. The exam expects you to connect a task to its hazards, select controls using the hierarchy, and verify that controls work.
359 words, about 2 min03Jobsite Safety Inspections and Audits
This domain tests how you plan and conduct inspections and audits, apply competent-person requirements, document findings, and drive corrective actions to closure. An inspection is frequent and compliance-focused; an audit is periodic, broader, and often independent, examining whether the safety system itself is working.
314 words, about 2 min04Incident Investigation, Documentation, and Reporting
This domain tests immediate response, evidence preservation, witness interviewing, causal analysis, corrective actions, and OSHA recordkeeping and reporting. The purpose is prevention and organizational learning, not assigning blame.
303 words, about 2 min05Emergency Preparedness and Response Planning
This domain tests site-specific emergency action planning, roles, communication, evacuation or sheltering, accounting for personnel, drills, first aid, fire protection, and rescue coordination. The exam expects plans that fit the site's actual hazards, not a generic handout.
292 words, about 1 min06Employee Safety Training and Communication
This domain tests how you deliver required training, verify understanding, document it, and communicate hazards in a way workers can act on. Training must be understandable to the employee, including language and literacy level.
299 words, about 1 min07Personal Protective Equipment and High-Risk Work Activities
This domain tests PPE selection, use, care, training, and controls for high-risk work: falls, excavations, confined spaces, cranes, electrical work, and hot work. PPE must fit the hazard and the worker, and it never replaces engineering or administrative controls.
288 words, about 1 min08Safety Leadership, Culture, and Supervisor Responsibilities
This domain tests how supervisors set expectations, enforce rules consistently, build worker participation, use stop-work authority, and shape a culture in which hazards and near misses are reported. Leadership is shown through decisions about production, staffing, recognition, and correction.
