Construction sites are fast-paced, high-energy environments where progress happens quickly — but so can accidents. From heavy machinery and elevated work areas to electrical systems and confined spaces, construction projects present a wide range of hazards every day. Ensuring safety on these sites isn’t optional; it’s essential.

That’s why trained safety professionals are in high demand across the industry. One of the most respected credentials for these professionals is the CHST certification, short for Construction Health and Safety Technician.

Whether you’re already working in construction safety or looking to advance your career, earning the CHST designation can significantly boost your knowledge, credibility, and earning potential. In this article, we’ll explore what CHST is, who it’s for, how to qualify, and why it matters so much in today’s construction industry.

What Is CHST?

The Construction Health and Safety Technician (CHST) certification is a professional credential awarded by the Board of Certified Safety Professionals (BCSP). It’s specifically designed for individuals who work directly in construction environments and are responsible for maintaining safe job sites.

Unlike general safety certifications that cover multiple industries, CHST focuses entirely on construction-related hazards, regulations, and best practices. It validates that a professional has the practical skills and knowledge needed to prevent accidents, reduce risks, and ensure compliance with safety standards.

In short, CHST demonstrates that you know how to keep construction workers safe.

Why Construction Safety Is So Important

Construction consistently ranks among the most hazardous industries worldwide. Workers face daily risks such as:

• Falls from scaffolding or ladders

• Equipment and machinery accidents

• Electrical hazards

• Trench and excavation collapses

• Struck-by incidents

• Exposure to hazardous substances

• Noise and respiratory risks

Even small mistakes can lead to serious injuries or fatalities. That’s why safety professionals are critical to every project.

CHST-certified technicians play a key role in identifying risks, training workers, and implementing procedures that prevent accidents before they happen. Their work not only protects employees but also saves companies from costly downtime, legal issues, and insurance claims.

Who Should Pursue CHST Certification?

The CHST certification is ideal for professionals who spend significant time on construction sites managing or supporting safety efforts.

Common job roles include:

• Construction safety officers

• Safety coordinators

• Site supervisors

• Field safety technicians

• Foremen with safety responsibilities

• Environmental health and safety (EHS) specialists

• Risk managers

• Project managers involved in safety compliance

If your daily tasks involve inspections, hazard assessments, safety training, or OSHA compliance, CHST is likely a great fit.

It’s especially valuable for professionals who want to move into leadership or specialized safety roles.

Eligibility Requirements

To ensure candidates have real-world experience, BCSP sets specific requirements before you can take the CHST exam.

Education

A high school diploma or equivalent is required. Unlike some certifications, a college degree is not mandatory.

Work Experience

You must have at least three years of construction safety experience.

Additionally, at least 35% of your job duties must involve safety-related tasks, such as:

• Conducting safety inspections

• Performing job hazard analyses

• Investigating incidents

• Delivering safety training

• Developing safety procedures

• Enforcing safety policies

These requirements ensure candidates understand the realities of construction work, not just theory.

What Does the CHST Exam Cover?

The CHST exam evaluates both knowledge and practical application. It focuses on real-world scenarios that safety professionals encounter daily.

Key content areas typically include:

Hazard Identification and Control

Recognizing unsafe conditions and implementing preventive measures to eliminate or reduce risks.

Construction Worksite Safety

Managing hazards related to scaffolding, ladders, fall protection, excavation, cranes, and heavy equipment.

Occupational Health Hazards

Addressing noise exposure, chemical hazards, air quality, respiratory protection, and ergonomics.

Safety Program Management

Developing policies, conducting audits, and ensuring regulatory compliance.

Emergency Preparedness

Responding effectively to fires, injuries, evacuations, and disasters.

Communication and Training

Teaching workers safe practices and promoting a positive safety culture.

The exam is typically multiple-choice and designed to test critical thinking rather than memorization.

How to Prepare for the CHST Exam

Preparing for the CHST exam requires dedication and structured study. Here are some helpful tips:

Review the Exam Blueprint

BCSP provides detailed outlines showing what topics are tested. Focus your study time accordingly.

Study OSHA Standards

OSHA regulations are a major component of construction safety and frequently appear on the exam.

Take Practice Tests

Practice questions help you become comfortable with the format and identify knowledge gaps.

Attend Prep Courses

Many organizations offer CHST preparation classes that provide guided instruction and real-life examples.

Use Field Experience

Apply your on-the-job knowledge. Many exam questions reflect practical scenarios you’ve likely encountered before.

Consistent preparation over several weeks greatly improves success rates.

Benefits of Becoming CHST Certified

Earning CHST offers both professional and personal advantages.

Greater Credibility

Certification signals expertise and professionalism to employers, coworkers, and clients.

More Job Opportunities

Many construction firms prefer or require CHST certification for safety positions.

Higher Salaries

Certified professionals often earn more due to their specialized knowledge.

Career Advancement

CHST can open doors to supervisory, managerial, or consulting roles.

Improved Skills

The knowledge gained during preparation enhances your ability to protect workers and manage risks.

Industry Recognition

BCSP certifications are respected globally, making your credentials portable across regions and employers.

CHST vs Other Safety Certifications

You may wonder how CHST compares to other safety credentials.

CHST

Focused specifically on construction safety and field-level professionals.

ASP (Associate Safety Professional)

Broader safety coverage across industries and often a stepping stone to higher certifications.

CSP (Certified Safety Professional)

Advanced credential for experienced safety leaders and managers.

If your primary focus is construction, CHST is often the most relevant starting point. You can pursue additional certifications later as your career grows.

Maintaining Your Certification

Certification doesn’t end after passing the exam. CHST holders must maintain their credentials through continuing education.

This typically includes:

• Earning continuing education units (CEUs)

• Participating in training or professional development

• Staying current with safety standards

• Paying renewal fees

This ensures certified professionals remain knowledgeable about new regulations, technologies, and best practices.

Real-World Impact of CHST Professionals

The value of CHST certification goes beyond resumes and salaries. It directly impacts lives.

Certified technicians often:

• Catch hazards before accidents happen

• Improve worker awareness

• Reduce injuries and fatalities

• Increase productivity

• Lower company costs

• Foster a culture of accountability

A single proactive safety measure — such as proper fall protection or improved signage — can prevent serious injuries or save lives.

That’s the true importance of CHST: protecting people.

Is CHST Worth It?

For most construction safety professionals, the answer is a clear yes.

The certification:

• Enhances your professional reputation

• Increases earning potential

• Strengthens job security
