CSO - Common Safety Orientation Hazard Recognition and Control Questions and Answers

Question 1

According to the hierarchy of controls, which of the following actions is considered the most effective method for controlling a hazard?

Accepted Answer

Physically removing the hazardous substance from the workplace entirely.

Answer

The hierarchy of controls ranks hazard control methods from most to least effective. Elimination, which is physically removing the hazard, is at the top and is the most effective control measure because it removes the hazard source completely.

Question 2

A worker on a construction site notices a large, unsecured puddle of oil on a main walkway, creating a significant slip hazard. What is the most appropriate immediate action for the worker to take?

Accepted Answer

Barricade or guard the area to prevent others from entering and report the hazard to their supervisor.

Answer

The first priority is to prevent immediate harm to others. The worker should take steps to isolate the hazard (e.g., by standing guard or using available materials to create a barrier) and then promptly report it to a supervisor so it can be properly addressed by trained personnel. This aligns with the principles of personal accountability and reporting hazards covered in CSO training.

Question 3

Which of the following is best classified as an ergonomic hazard?

Accepted Answer

Poorly designed workstations that require workers to perform tasks in awkward postures.

Answer

Ergonomic hazards relate to the design of the work environment and tasks that can cause strain on the body over time. A poorly designed workstation forces awkward postures, which can lead to musculoskeletal injuries. Frayed cords are safety hazards, loud noise is a physical hazard, and viruses are biological hazards.

Question 4

Installing a guardrail around an elevated platform is an example of which type of hazard control?

Accepted Answer

Engineering Control

Answer

Engineering controls are methods that are built into the design of a plant, equipment, or process to minimize the hazard. A guardrail is a physical structure that isolates people from the fall hazard, making it an engineering control.

Question 5

Which of the following is a primary goal of conducting a worksite hazard assessment?

Accepted Answer

To identify existing and potential dangers in order to implement controls and prevent incidents.

Answer

The fundamental purpose of a hazard assessment is to proactively identify and evaluate workplace hazards so that effective control measures can be implemented to prevent accidents, injuries, and illnesses.
