CHST - Construction Health and Safety Technician Construction Health and Safety Technician 1 — Questions and Answers
Question 1: Under OSHA's Hazard Communication Standard (29 CFR 1910.1200), Safety Data Sheets (SDS) must contain how many sections?
- 8 sections
- 12 sections
- 16 sections (Correct answer)
- 20 sections
Correct answer: 16 sections
OSHA's HazCom Standard, aligned with the Globally Harmonized System (GHS), requires SDS to follow a standardized 16-section format covering identification, hazard identification, composition, first-aid measures, and more.
Question 2: What is the maximum noise exposure level permitted by OSHA (29 CFR 1926.52) for an 8-hour workday before engineering controls or hearing protection are required?
- 80 dBA
- 85 dBA
- 90 dBA (Correct answer)
- 95 dBA
Correct answer: 90 dBA
OSHA's construction noise standard sets the permissible exposure limit (PEL) at 90 dBA as an 8-hour time-weighted average (TWA). Exposures above this threshold require engineering controls, administrative controls, or hearing protection.
Question 3: Under OSHA's Scaffolding standard (29 CFR 1926.451), supported scaffolds must be capable of supporting their own weight plus at least how many times the maximum intended load?
- 2 times
- 3 times
- 4 times (Correct answer)
- 6 times
Correct answer: 4 times
OSHA requires supported scaffolds to be designed and constructed to support their own weight and at least 4 times the maximum intended load. This safety factor ensures structural integrity under dynamic and static loading conditions.
Question 4: Which OSHA standard specifically governs the use of personal protective equipment (PPE) for eye and face protection on construction sites?
- 29 CFR 1926.100
- 29 CFR 1926.101
- 29 CFR 1926.102 (Correct answer)
- 29 CFR 1926.103
Correct answer: 29 CFR 1926.102
29 CFR 1926.102 covers eye and face protection in construction, requiring appropriate protection against flying particles, molten metal, liquid chemicals, acids, caustic liquids, chemical gases, and light radiation hazards.
Question 5: According to OSHA's Lockout/Tagout standard (29 CFR 1910.147), which of the following is true regarding tagout devices compared to lockout devices?
- Tagout provides equivalent protection to lockout in all situations
- Tagout may be used only when the energy isolating device is not capable of being locked out (Correct answer)
- Tagout is the preferred method when working on electrical systems
- Tagout devices must be removed by the same employee who attached them, with no exceptions
Correct answer: Tagout may be used only when the energy isolating device is not capable of being locked out
Under OSHA's LOTO standard, tagout is permitted only when the energy isolating device is not capable of being locked out. Lockout is the preferred method because it physically prevents re-energization, while a tagout is only a warning device.
Question 6: On a construction site, a Safety and Health Program must include which of the following four core elements according to OSHA guidelines?
- Management leadership, worker participation, hazard identification, hazard prevention and control (Correct answer)
- Incident investigation, training, PPE issuance, emergency response planning
- Toolbox talks, daily inspections, OSHA 300 log maintenance, SDS management
- Subcontractor oversight, safety incentive programs, drug testing, and return-to-work policies
Correct answer: Management leadership, worker participation, hazard identification, hazard prevention and control
OSHA's Recommended Practices for Safety and Health Programs identify four core elements: management leadership, worker participation, hazard identification and assessment, and hazard prevention and control. These form the foundation of an effective safety management system.
