Construction is one of the most hazardous industries, and the people who keep crews safe carry real responsibility. The Construction Health and Safety Technician (CHST)® credential from the Board of Certified Safety Professionals (BCSP) gives that experience a recognized name. It tells employers, owners, and general contractors that you can identify hazards, run a site safety program, and lead people toward safer work.

In this guide, we’ll cover who the CHST is for, the eligibility rules, how long it takes to study, the careers and pay it connects to, how to maintain it, and which credentials make sense next.

Who Should Take the BCSP CHST Exam?

The CHST is for people who handle safety on construction projects, whether it is their whole job or just one part of it. BCSP notes that CHSTs may work for an owner, general contractor, subcontractor, or firm involved in SH&E practice.

You’re a strong fit if you work in roles like these:

  • Site safety coordinators and safety technicians who run daily inspections, JHAs, and toolbox talks.
  • Superintendents and foremen with a meaningful share of safety duties who want documented credibility.
  • Safety representatives for subcontractors in trades like electrical, steel erection, concrete, or excavation.
  • Owner’s representatives and safety consultants who audit contractor programs on large projects.
  • Safety professionals moving into construction from general industry who have built up the required construction experience.

You may want to wait if you don’t yet have three years of construction safety experience, or if safety tasks make up only a small slice of your job. If you supervise crews and want a first credential, BCSP’s Safety Trained Supervisor Construction (STSC)® may be a better starting point.

What Are the BCSP CHST Eligibility Requirements?

The CHST requirements are short and experience-focused. According to the BCSP CHST page, you need:

  • Experience: Three years of experience in construction safety, with at least 35% of your job duties requiring technical skills and knowledge in safety, health, and environment (SH&E).
  • Education: No specific degree or academic requirement.
  • Exam: A passing score on the CHST examination.
  • Maintenance: An annual renewal fee and recertification requirements once certified.

The 35% threshold is important. Your application should clearly state which duties were SH&E work, such as conducting inspections, developing site-specific safety plans, training workers, or investigating incidents.

How Do You Apply?

  1. Create an account and apply online through BCSP’s “My Profile” portal.
  2. Pay the application fee. BCSP reviews your application after payment.
  3. Once approved, purchase your exam and schedule it at a Pearson VUE test center. You have one year from approval to take and pass the exam.
  4. If you need to retest, schedule at least six weeks after your previous attempt.

How Much Does the CHST Cost?

BCSP’s Credentials At-A-Glance page lists a $140 application fee and a $300 exam fee, with a $550 exam bundle option. Once certified, the annual renewal fee is $145. Fees can change, so check that page before you apply. BCSP’s A Complete Guide to Safety Certification has details on accommodations, ID, and testing rules.

How Long Should You Study for the BCSP CHST Exam?

Most candidates do well with two to four months of steady study at about five to eight hours per week. Because everyone sitting the exam already has three years in the field, the question is less about learning construction and more about filling gaps in areas you don’t handle every day.

  • Plan for four months or more if your work is concentrated in one trade, you rarely deal with health hazards like silica or lead, or you haven’t been involved in emergency planning or training design.
  • Two months may be enough if you already run broad site safety programs, work directly with 29 CFR 1926 daily, and score well on a mixed baseline.

A Sample 12-Week CHST Study Plan

  • Week 1: Read the CHST5 blueprint, take a mixed baseline quiz, and rank each domain by weakness.
  • Weeks 2–5 (Domain 1, 36.6%): Work through fall protection, scaffolds and ladders, excavations, electrical, cranes and rigging, then health hazards (silica, noise, lead, asbestos, heat) and the hierarchy of controls.
  • Weeks 6–7 (Domain 3, 22.5%): Site-specific safety plans, inspections, recordkeeping, incident causation methods, and trend analysis.
  • Weeks 8–9 (Domain 4, 21%): Adult learning and training methods, behavior and motivation, communication, and leadership strategies.
  • Week 10 (Domain 2, 19.9%): Emergency action plans, fire protection, incident command, first aid, spill response, and notifications.
  • Week 11: Mixed practice across all domains and a focused pass through every missed question.
  • Week 12: Timed sets to build pacing (about 72 seconds per question), light review, and rest before exam day.

What Careers Can the BCSP CHST Support?

The CHST fits naturally into construction safety roles such as site safety manager, construction safety coordinator, EHS specialist for a contractor, and safety consultant. Many owners and general contractors look for or require recognized safety credentials for on-site safety staff, especially on large or public projects, so the CHST can help you qualify for those positions. It does not guarantee a job or specific pay, and employers also weigh experience, project size, and leadership scope.

What Is the Salary for a CHST?

BCSP-specific salary figures vary, so a reliable benchmark is the U.S. Bureau of Labor Statistics (BLS). According to the BLS Occupational Outlook Handbook, as of May 2025:

  • The median annual wage for occupational health and safety technicians was $61,560, and $74,330 for technicians working in construction.
  • The median annual wage for occupational health and safety specialists was $90,150, and $94,670 for specialists working in construction.

The outlook is strong. BLS projects employment of occupational health and safety specialists and technicians to grow 19% from 2025 to 2035, much faster than average, with about 20,900 openings each year. Your own pay will depend on your region, project types, and how much of your role is dedicated to safety.

How Do You Maintain the CHST?

The CHST runs on a five-year recertification cycle. According to BCSP’s handbook, CHSTs must earn and submit 20 recertification points every five years to stay current with professional practice, and you also pay the annual renewal fee. BCSP recertification cycles normally run from July 1 to June 30.

Points come from activities such as continuing education, training, and professional involvement. Check the BCSP Recertification Guide for eligible activities, how to claim points, and required documentation.

What Certifications Stack Well With the BCSP CHST?

The most useful next steps build on your construction focus or open up a larger professional role:

  • Associate Safety Professional (ASP)®: A step toward professional-level safety roles. It requires at least a bachelor’s degree in any field (or an associate degree in SH&E) and one year of SH&E experience that is at least 50% preventive, professional-level work.
  • Certified Safety Professional (CSP)®: BCSP’s flagship credential for safety managers and directors. It requires a bachelor’s degree, four years of qualifying SH&E experience, and a BCSP-approved credential such as the ASP.
  • Certified Instructional Trainer (CIT)®: A good fit if you design and deliver a lot of safety training. It requires 135 hours of SH&E teaching, training, or development.
  • Occupational Hygiene and Safety Technician (OHST)®: Useful if your work moves into general industry or heavier exposure monitoring.

Credential requirements can change, so confirm them on BCSP’s Credentials At-A-Glance page before you plan your next step.
