Workplace Safety Hazards Quiz

Hazards and Unsafe Acts

• Hazardous conditions are circumstances that can lead to accidents.
• Unsafe acts account for 80% of injuries, primarily due to human factors such as:
  • Lack of fitness for work
  • Use of unsafe equipment
  • Adjusting moving machinery
  • Improper lifting techniques
  • Engaging in horseplay
  • Drug or alcohol influence
  • Operating without authorization
  • Failure to wear Personal Protective Equipment (PPE)
  • Taking unnecessary shortcuts

Unsafe Conditions

• Unsafe working conditions contribute to 20% of injuries, often stemming from latent organizational weaknesses, including:
  • Poor workplace layout or congestion
  • Excessive noise exposure
  • Inadequate housekeeping measures
  • Insufficient machine guards and warning systems
  • Use of defective tools or materials
  • Poor illumination or ventilation

Accident Theories

• Understanding accidents involves various theories that seek to explain their causes:
  • Domino Theory: Accidents result from a chain of events, each dependent on the previous factor.
  • Human Factors Theory: Focuses on the impact of human behavior and error.
  • Swiss Cheese Model: Illustrates how layers of defenses can have holes, leading to accidents if holes align.

Definitions

• Accident: Sudden unplanned events without an apparent cause; can result in injury.
• Incident: Occurs during work that could lead to injury or ill health.
• Occurrence: An extended incident over time, not just a single event.
• Near Miss: An event that could have resulted in injury but didn't.

Herbert William Heinrich

• Heinrich (1886-1962) was a pioneer in workplace safety; introduced the Domino Theory in 1932, stating:
  • 88% of injuries are caused by unsafe acts, 10% by unsafe conditions, and only 2% are deemed unavoidable.

Error Types

• Active Errors: Immediate errors that lead to undesired consequences.
• Latent Errors: Undetected flaws in systems or organizational weaknesses that can trigger active errors.
• Human errors account for about 70% of incidents; system-induced errors about 30%.

Active vs. Latent Failures

• Latent Conditions: Pre-existing weaknesses like budget cuts, poor training, and workload issues that can enable unsafe acts.
• Active Failures: Direct unsafe actions taken by individuals, such as ignoring safety protocols.

Preventative Strategies

• Redundancy: Implementing multiple layers of protection.
• Diversity: Utilizing various protective measures to mitigate risks.
• Independence: Ensuring protective layers operate autonomously to enhance safety.

Error-Likely Situations

• Situations that increase error likelihood are predictable and may arise from:
  • High task demands, unfamiliarity with tasks, and unclear responsibilities.
  • Environmental factors such as distractions, fatigue, and confusion.

Conclusion

• No single theory can explain all workplace incidents; a comprehensive understanding is essential for effective prevention.
