Safety Trained Supervisor Safety Trained Supervisor 3 — Questions and Answers
Question 1: A permit-required confined space is characterized by which feature?
- It has limited lighting
- It has limited or restricted means of entry/exit and is not designed for continuous occupancy (Correct answer)
- It is located below ground level
- It requires a supervisor to be present at all times
Correct answer: It has limited or restricted means of entry/exit and is not designed for continuous occupancy
OSHA defines a permit-required confined space as one with limited entry/exit, not designed for continuous occupancy, and containing a serious safety or health hazard.
Question 2: The 'near-miss' reporting system in a safety program primarily serves to:
- Identify employees who violate safety rules
- Capture incident data for OSHA recordkeeping only
- Proactively identify hazards before an injury occurs (Correct answer)
- Calculate workers' compensation premiums
Correct answer: Proactively identify hazards before an injury occurs
Near-miss reporting helps organizations identify and correct hazards before they result in an actual injury or illness.
Question 3: Under OSHA's fall protection standard for general industry, fall protection is required when working at or above:
- 4 feet (Correct answer)
- 6 feet
- 8 feet
- 10 feet
Correct answer: 4 feet
OSHA 29 CFR 1910.28 requires fall protection in general industry for unprotected sides and edges 4 feet or more above a lower level.
Question 4: Which document outlines the specific steps, hazards, and controls for performing a high-risk task safely?
- Incident investigation report
- Safe Work Procedure (SWP) (Correct answer)
- OSHA 300 log
- Training needs assessment
Correct answer: Safe Work Procedure (SWP)
A Safe Work Procedure (SWP) documents step-by-step instructions including identified hazards and controls for a specific task.
Question 5: What is the primary purpose of a safety observation program?
- To discipline employees for unsafe behavior
- To monitor compliance with union contracts
- To identify unsafe behaviors and conditions before they cause injury (Correct answer)
- To satisfy OSHA audit requirements
Correct answer: To identify unsafe behaviors and conditions before they cause injury
Safety observation programs proactively identify at-risk behaviors and hazardous conditions so corrective action can occur before an incident.
Question 6: When investigating an accident, the root cause analysis technique known as '5 Whys' involves:
- Asking five different witnesses for their perspectives
- Repeatedly asking 'why' to drill down to the underlying cause of an event (Correct answer)
- Identifying five corrective actions for every incident
- Rating the severity of five hazard categories
Correct answer: Repeatedly asking 'why' to drill down to the underlying cause of an event
The 5 Whys technique iteratively asks 'why' after each answer to trace a problem back to its root cause.
Question 7: According to OSHA, which of the following is an example of an engineering control?
- Posting warning signs near hazardous areas
- Rotating workers to reduce exposure time
- Installing machine guarding on a press (Correct answer)
- Requiring workers to wear safety glasses
Correct answer: Installing machine guarding on a press
Engineering controls like machine guarding physically modify the work environment or equipment to reduce or eliminate hazard exposure.
