The CHST (Construction Health and Safety Technician) is a professional credential administered by the Board of Certified Safety Professionals (BCSP) for individuals working in construction safety roles. Earning the CHST demonstrates competency in hazard recognition, safety program implementation, and regulatory compliance specific to construction environments. Candidates must meet eligibility requirements including work experience in construction safety and pass a 200-question multiple-choice examination covering four blueprint domains.
The CHST exam allocates questions across domains including program management, worksite auditing, training, and hazard identification, with OSHA construction standards (29 CFR 1926) forming the regulatory backbone of the test. Candidates have 4 hours to complete the computer-based exam at Pearson VUE testing centers, and a scaled score of 200 out of a possible 250-350 range is required to pass.
The Certified Health and Safety Technician (CHST) is a professional credential administered by the Board of Certified Safety Professionals (BCSP). It is designed for practitioners who work in health and safety operations, including hazard recognition, safety program implementation, and regulatory compliance at the field level. Unlike the CSP, which targets management-level safety professionals, the CHST focuses on the technical and hands-on aspects of workplace safety. Candidates must meet education and experience requirements before sitting for the exam, which covers four primary domains: hazard recognition, hazard control, safety program management, and emergency preparedness. The CHST designation signals to employers that a technician has demonstrated verified competency in occupational safety practices aligned with OSHA standards and ANSI guidelines.
The CHST exam consists of 200 multiple-choice questions, of which 175 are scored and 25 are unscored pretest items. Candidates are given 4 hours to complete the exam. The four tested domains on the current CHST5 blueprint are weighted as follows: Hazard and Risk Identification and Control (36.6%), Emergency Preparedness, Incident Investigation, and Response (19.9%), Safety Program Development, Implementation, and Sustainment (22.5%), and Leadership, Communication, and Training (21%). The exam is administered at Pearson VUE testing centers throughout the United States. A scaled passing score is determined through a modified Angoff method, meaning the cut score reflects the minimum competency level established by subject matter experts rather than a fixed percentage. Candidates who do not pass may retake the exam no sooner than six weeks after their last attempt, within their one-year eligibility window. Maintaining the CHST requires earning 20 recertification points within a five-year cycle, which can be fulfilled through continuing education, professional development activities, or retaking the exam.
Holding the CHST credential directly affects hiring competitiveness and earning potential in the safety field. According to BCSP survey data, certified safety technicians report higher median salaries than their non-certified counterparts, with many CHST holders working in construction, manufacturing, oil and gas, and government sectors. Federal contractors and companies operating under OSHA's Voluntary Protection Programs (VPP) frequently list the CHST as a preferred or required qualification in job postings. The credential also serves as a stepping stone toward advanced certifications such as the ASP and CSP, since BCSP allows CHST holders to apply relevant experience toward those higher-level credentials. For safety technicians looking to move beyond entry-level field roles into supervisory or program coordination positions, the CHST provides documented proof of technical proficiency that hiring managers recognize across industries.

CHST practice questions are most useful when you treat them as a diagnostic tool rather than a memory test. Start with an untimed set of CHST practice test questions and read every answer explanation, including the ones you got right, so you understand why the correct option beats the distractors. Tag each missed question by blueprint domain (hazard and risk identification and control; emergency preparedness, incident investigation, and response; safety program development, implementation, and sustainment; or leadership, communication, and training) and you will quickly see where your study time should go.
Because the CHST is built around construction work, many items are scenario-based: a trench without a protective system, a scaffold missing guardrails, an unprotected floor opening, or a crew working near energized lines. When you miss one, look up the governing rule in OSHA's construction standards (29 CFR 1926) instead of only memorizing the answer. Subparts such as P (Excavations), L (Scaffolds), M (Fall Protection), and K (Electrical) come up constantly in field safety work.
Once your untimed accuracy is consistent, switch to timed sets to build pacing, and revisit the questions you missed a few days later to confirm the concept stuck. Finish your review with the official BCSP blueprint and reference list so nothing on the outline is left uncovered.

A CHST discovers that a subcontractor is falsifying injury logs on a project where the CHST works for the general contractor. The CHST's primary ethical obligation is to:
Answer: B. Notify GC management and document the concern; escalate to OSHA if the GC fails to act
Falsifying OSHA 300 logs is a federal violation (29 CFR 1904). The CHST's ethical duty is to report the concern to GC management with documentation, since the GC has supervisory responsibility over subcontractors on-site. If management fails to act, escalation to OSHA fulfills the duty to uphold regulatory compliance. Going directly to OSHA before internal escalation skips the CHST's professional duty to act through appropriate channels first.
The CHST exam is administered by which certifying organization?
Answer: B. Board of Certified Safety Professionals (BCSP)
The CHST credential is awarded and administered by the Board of Certified Safety Professionals (BCSP).
A CHST is pressured by a project manager to sign off on a scaffold inspection knowing the scaffold does not meet OSHA standards. According to BCSP's Code of Ethics, the CHST should:
Answer: B. Refuse to certify the scaffold and report the deficiency through appropriate channels
BCSP's Code of Ethics requires certificants to hold worker safety paramount above employer directives. Signing an inaccurate safety certification is both an ethical violation and potential legal liability. The CHST must refuse, document the deficiency, and escalate through appropriate channels (management, OSHA if necessary).
A safety equipment vendor offers a CHST a free golf outing in exchange for recommending the vendor's harnesses on the project. Accepting this offer most directly violates which BCSP ethical principle?
Answer: B. Conflict of interest — a personal benefit could influence a professional decision affecting worker safety
Accepting gifts or benefits from vendors whose products you are in a position to recommend creates a conflict of interest under BCSP's Code of Ethics. The professional's judgment about worker protection equipment must be free from personal benefit. The CHST should decline the offer and make equipment recommendations solely on merit.
