Free CHST Practice Test
The Construction Health and Safety Technician (CHST) Exam is a certification examination written by the Council on Certification of Health, Environmental, and Safety Technologists (CCHEST) and administered by Pearson VUE that is designed to determine if an individual has the knowledge necessary to work as a health and safety specialist in a construction setting.
This exam assesses the individual's understanding of managing a construction site, training individuals in OSHA regulations, maintaining a safe work environment through worksite audits, and ethical and legal concerns involved with the health and safety of workers at a worksite. This certification is not required in order to work as a health and safety specialist, but it can be an extremely effective resume-builder for individuals seeking careers in construction health and safety or individuals seeking advancement in a construction-related career. The exam consists of 200 multiple-choice questions that are related to the following four areas:
- Program Management (Approximately 58 questions)
- Worksite Auditing (Approximately 80 questions)
- Training (Approximately 54 questions)
- Professional Responsibility (Approximately 8 questions)
The exam-taker will have four hours to complete the exam and the exam-taker will receive a pass/fail grade based on whether or not he or she makes enough correct responses to meet or exceed the threshold set by the CCHEST. The exact number of correct responses required to pass the exam varies depending on the specific version of the exam that the individual receives and the difficulty of each question included on that version of the exam. In order to register for the CHST Exam, the individual seeking certification must have a high school diploma and must be an OSHA authorized instructor or have 40 hours of classroom training related to construction health and safety or three years of construction experience. The individual will also be eligible to take the exam without meeting these requirements if the individual has an associate's degree or higher related to a health and safety field or has completed 9 semester hours of college courses related to a health and safety field. If the individual meets one of these requirements and has at least one year of work experience in a construction work environment, he or she may register for the exam by submitting an application to CCHEST and, if the application is accepted, he or she will receive instructions on how to schedule a testing date with Pearson VUE. The current registration fee for the exam is $355, which includes both the application fee and the examination fee.
1. The best choice to protect eyes from dust is to wear
a. Safety spectacles without side shields
b. Safety spectacles with side shields
d. Full-face welding shields

b. Every six months
d. After each use
3. The most appropriate technique that construction safety professionals can use to analyze system safety at smaller worksites is
a. Job Safety Analysis (JSA)
b. Management Oversight and Risk Tree Analysis (MORT)
c. Fault Tree
d. Probabilistic Risk Assessment
4. If more than 25 employees are working underground, the following safety procedure(s) must be in place:
a. A designated person posted aboveground must keep count of the underground workers
b. Two rescue teams must be available
c. Entries and exits to the underground work area must be posted with safety signs
d. All of the above
5. If a trench 3 feet deep is dug in gravel material, what must the angle of the trench wall be?
a. 45 degrees
b. 53 degrees
c. 63 degrees
d. 75 degrees
CHST Answers and Explanations
1. C: Tight-fitting goggles completely cover the eyes, providing protection from dust as well as from flying objects and chemical splashes.
2. B: Insulating gloves must be tested within a six-month period, and the test procedures and results must be recorded. Insulating rubber gloves can be worn under leather gloves to provide protection from additional dangers such as punctures or pinching.
3. A: Job Safety Analysis (JSA) is the most appropriate choice for small construction worksites because skilled workers familiar with the site and job functions perform the analysis. Fault Tree methods evaluate the potential causes of an injury or illness to predict future events, while Probabilistic Risk Assessment considers the severity and likelihood of events. MORT analyzes the causes of injuries and looks for weaknesses in safety plans; however, its 1,500 data components make it less useful for worksite analysis.
4. D: Safety signs must be posted at entries and exits of all underground work areas. In addition, an aboveground person must always count the number of underground workers. When more than 25 workers are underground, two rescue teams must be available, one within 30 minutes of traveling distance and one within two hours. If fewer than 25 workers are underground, one rescue team must be available within 30 minutes of traveling distance.
5. A: Gravel and silt are Type B materials, which require a height-to-depth ratio of 1:1. A 3-foot trench requires a 3-foot angle, or 45 degrees. Clay is a Type A material and requires a minimum 53 degree slope. Type C is sand. The slope of Type C trenches must be at least 63 degrees. In addition, a Type C trench can be no more than 11 feet deep.
