Medical Gas Line Inspection — Branching Scenario
Project Overview
Designing a skills-based branching scenario that prepares hospital facilities technicians to inspect and secure medical gas pipeline connections in patient care environments.
The activity focuses on applying NFPA 99 standards through realistic decision-making, where accuracy, material choice, and sequencing directly affect patient safety and system readiness.
Designing the Branching Scenario
The scenario places learners in the role of a hospital facilities technician assigned to prepare a ward for reopening. Learners work through three inspection and securing tasks that reflect common—but high-risk—medical gas line situations.
Each task requires learners to assess conditions, select compliant actions, and understand how even small deviations can compromise safety, inspections, and clinical operations.
Client Context
Hospital medical gas systems are critical infrastructure, yet training often relies heavily on documentation and observation rather than applied decision-making.
The client needed a way for learners to practice applying NFPA 99 requirements before performing live inspections—especially in situations where mistakes may not be immediately visible but carry serious patient risk.
What this Branching Scenario is (and isn’t)
-
It is a skills-focused immersive practice, not a knowledge check.
-
It reinforces regulatory standards through applied decisions.
-
It makes safety consequences visible through performance indicators.
- It is not a physical simulation, but a preparation for supervised on-site work.
Design Approach
The scenario is structured as a linear branching experience with graded response options at each decision point. Learners receive immediate technical feedback tied to healthcare standards, along with cumulative performance tracking.
Two visual indicators are used: a task-level efficiency gauge and a global patient readiness bar. Together, these help learners see how individual actions contribute to overall system safety and compliance.
Key Components
- NFPA 99–aligned inspection and securing scenarios
-
Graded decision responses (correct, partial, incorrect)
-
Task-level performance efficiency indicators
-
Global patient readiness tracking across tasks
-
Consequence-based feedback tied to safety and compliance
-
Reflection and remediation guidance based on score bands
Role & Contribution
I designed the scenario structure, decision logic, scoring model, and feedback framework.
This included translating regulatory standards into actionable decisions, defining performance indicators, and shaping feedback to reinforce both technical accuracy and professional responsibility in healthcare environments.
Outcome
The scenario enables learners to practice judgment in a controlled environment before working on live medical gas systems.
It supports stronger regulatory understanding, reduces superficial compliance, and builds confidence in applying safety standards consistently under operational pressure.
Reflection
This work demonstrates how immersive practice can be used to teach precision, accountability, and risk awareness in healthcare infrastructure roles.
By connecting decisions to patient readiness—not just task completion—the scenario reinforces the real-world impact of facilities work on clinical safety and care quality.
