When a workplace accident occurs, confusion often follows. People scramble to figure out what went wrong, how it happened, and what can be done to prevent it from happening again. But too often, investigations stop at surface-level answers—like “human error” or “equipment failure.” That’s not enough. To build a truly safe workplace, we need to look deeper.
This is where tools like the 5 Whys and Fishbone Diagrams come in. They help us move from chaos to clarity by digging beneath the surface and uncovering the systemic failures that often lead to workplace hazards. These tools are easy to learn, practical to apply, and incredibly effective—especially when combined with formal safety training. In fact, many professionals opt for certifications like NEBOSH to strengthen their investigative skills. The NEBOSH course fees in Pakistan are affordable for most safety professionals and offer excellent value for the depth of training provided.
Why Proper Training Matters
Many workplace safety professionals in Pakistan are turning to internationally recognized qualifications to enhance their investigation skills. Among the most trusted is the NEBOSH International General Certificate (IGC). It’s widely respected and provides a solid foundation in risk assessment, hazard control, and root cause analysis.
If you’re wondering about NEBOSH course fees in Pakistan, they typically range from PKR 120,000 to PKR 180,000 depending on the institute and learning mode (online or classroom). This investment not only boosts your credentials but also equips you with tools like the 5 Whys and Fishbone Diagrams for real-world use.
What Is the 5 Whys Technique?
Breaking It Down
The 5 Whys is a simple but powerful tool. You start with the problem and ask “Why?” five times—or until you reach the root cause.
Example: Minor Electrical Fire
Let’s say a small electrical fire broke out in a warehouse. A poor investigation might blame it on “faulty wiring” and stop there. But by applying the 5 Whys:
- Why was there a fire? — Because of faulty wiring.
- Why was the wiring faulty? — Because it was old and worn out.
- Why wasn’t the wiring replaced? — Because no one flagged it during inspections.
- Why weren’t inspections thorough? — Because there’s no formal inspection checklist.
- Why isn’t there a checklist? — Because the company hasn’t implemented a structured safety program.
Now you’ve uncovered a systemic failure—not just faulty wiring, but a breakdown in safety processes.
What Is a Fishbone Diagram?
Also known as the Ishikawa Diagram, this tool helps organize potential causes of a problem into categories. It’s shaped like a fishbone, with the “head” representing the problem and the “bones” showing different cause categories.
Common Categories in Workplace Hazards:
- People – Training, fatigue, communication
- Process – Procedures, documentation
- Equipment – Maintenance, condition
- Environment – Lighting, noise, weather
- Materials – Defects, shortages
- Management – Leadership, culture, scheduling
By brainstorming within each of these areas, you can visually map out all contributing factors—and identify where improvements are needed.
Step-by-Step Guide: Using 5 Whys and Fishbone Together
- Start with the Problem
- Clearly define what went wrong. For example: “A worker slipped and fell near a chemical tank.”
- Draw the Fishbone
- Create categories that are relevant to your workplace—People, Process, Environment, etc.
- Brainstorm Possible Causes
- Fill in each “bone” of the fish with contributing factors. Maybe the floor was slippery, lighting was poor, or the worker lacked PPE.
- Pick One Key Cause to Explore with 5 Whys
- Let’s say you choose “slippery floor.”
- Ask “Why?” repeatedly:
- Why was the floor slippery?
- Why wasn’t it cleaned?
- Why didn’t anyone report the spill?
- Why aren’t there cleaning protocols?
- Why hasn’t anyone been assigned responsibility?
- Document Findings
- Use these insights to make real, effective changes—like setting clear cleaning schedules or improving hazard reporting.
Real-Life Example: A Forklift Incident
A company faced repeated forklift accidents. Management initially blamed driver carelessness. But one safety officer, recently NEBOSH-certified, used a Fishbone Diagram to dig deeper.
- People: Inexperienced drivers
- Equipment: No backup alarms
- Process: No speed limits set
- Environment: Narrow aisles
Then he applied the 5 Whys to the aisle issue:
- Why are forklifts hitting racks? — Because aisles are too narrow.
- Why are aisles narrow? — Because storage layout is dense.
- Why is the layout dense? — To save space.
- Why prioritize space over safety? — Because of lack of risk assessment.
- Why no risk assessment? — No trained personnel to conduct it.
That’s the power of using structured analysis tools—they help shift the blame from individuals to the system.
Benefits of These Tools in Hazard Investigations
- Promote a Blame-Free Culture: Focus on systems, not scapegoats.
- Enable Preventive Actions: Stop future incidents before they happen.
- Support Legal Compliance: Documented, thorough investigations meet legal and insurance standards.
- Encourage Worker Involvement: Clear visuals like Fishbone Diagrams make it easier to include team input.
Why Formal Safety Training Is a Game-Changer
Tools are only effective when you know how to use them properly. That’s where certifications like NEBOSH come in. Through structured modules and real-world scenarios, you learn to use analytical tools, assess risks, and drive safety culture.
If you’re serious about workplace safety, it’s worth exploring the NEBOSH course duration and fees in Pakistan. Many institutes offer flexible schedules and payment options to suit both working professionals and full-time learners.

Final Thoughts
Understanding why accidents happen goes far beyond pointing fingers. It’s about getting to the heart of the problem—and tools like 5 Whys and Fishbone Diagrams help you do exactly that. When paired with proper training and a proactive mindset, they turn confusion into clear, actionable insight.
