Case Study:
Scenario-Based eLearning for Basic H₂S Safety Training
Client
A leading marine safety training provider in the Middle East, headquartered in the UAE.
Challenges
Basic H₂S (Hydrogen Sulfide) safety training is a mandatory certification course for individuals working in offshore and marine environments. However, the client’s existing training program was:
-
Outdated and heavily reliant on traditional, instructor-led methods.
-
Inefficient in terms of learner engagement and training throughout.
-
Not fully adapted to online delivery formats, despite a growing demand for remote learning options.
Given the critical nature of H₂S awareness, the client needed a modern, impactful, and scalable training solution.
Solution
Applebox Media created a scenario-based eLearning course grounded in real-life relevance:
-
The instructional design team developed the training around an actual tragic incident that occurred on an offshore SPUD CAN.
-
The course was structured into multiple modules with key segments such as What Went Wrong, Root Cause Analysis, and Preventive Measures
-
Realistic scenarios helped learners visualize critical safety risks and procedures.
-
Integrated assessments (5 questions per module) evaluated knowledge retention and comprehension.


Result
-
A highly immersive and emotionally resonant eLearning experience.
-
Greater understanding of real-world risks and appropriate responses during H₂S-related incidents.
-
Faster, standardized training delivery for both self-paced learning and online classroom support.
-
Helped streamline certification, increasing operational readiness and safety compliance.
