An investigation into a workplace incident reveals that an employee slipped on a patch of oil. Further inquiry shows the oil was from a leaking gasket on a piece of machinery, and the preventative maintenance schedule for that machine was not being followed. What is the root cause of this incident?
Answer: Failure to adhere to the preventative maintenance program.
The root cause is the fundamental, system-related reason an incident occurred. While the oil patch was the immediate cause and the leaking gasket was a contributing factor, the failure of the preventative maintenance program is the systemic issue that, if corrected, would prevent a recurrence.
According to OSHA regulations in the United States, what is the mandatory reporting timeframe for a work-related incident that results in the in-patient hospitalization of one employee?
Answer: Within 24 hours
OSHA requires employers to report any work-related in-patient hospitalization, amputation, or loss of an eye within 24 hours of learning about it. A work-related fatality must be reported within 8 hours.
Which of the following is the primary purpose of conducting a thorough incident investigation in an HSE management system?
Answer: To identify root causes and implement corrective actions to prevent recurrence.
The most important reason for investigating a workplace incident is to identify its root causes to prevent similar events from happening again. While investigations help fulfill legal requirements and determine costs, their main function is preventative. Focusing on blame hinders the investigation and damages safety culture.
A forklift operator narrowly avoids hitting a pedestrian in a warehouse aisle because the pedestrian was wearing noise-canceling headphones and did not hear the backup alarm. This event, which had the potential for injury but did not result in one, should be reported and investigated as a:
Answer: Near miss
A near miss is an unplanned event that did not result in injury, illness, or damage but had the potential to do so. Investigating near misses is crucial as they serve as early warnings for potential hazards and system weaknesses that could lead to actual incidents if left unaddressed.
When developing corrective actions following an incident investigation, which strategy is considered MOST effective according to the hierarchy of controls?
Answer: Installing physical barriers to separate pedestrian walkways from forklift traffic (Engineering Control).
The hierarchy of controls ranks risk control methods from most to least effective. Engineering controls, which physically separate people from the hazard, are more effective than administrative controls (changing how people work) and Personal Protective Equipment (PPE), which rely on human behavior.
An incident investigation team is using the '5 Whys' technique to determine the root cause of an equipment malfunction. What is the fundamental process of this method?
Answer: Asking 'Why?' repeatedly until the underlying systemic cause is identified.
The '5 Whys' is an iterative interrogative technique used to explore the cause-and-effect relationships underlying a particular problem. The primary goal is to determine the root cause by repeatedly asking the question 'Why?', with each answer forming the basis of the next question until a systemic issue is uncovered.
