01 / WORKSPACE

A workplace
in motion.

How can crews reach a patient and their equipment while staying protected in a moving ambulance?

  • Care tasks
  • Crew protection
  • Equipment restraint

05 / TRAINING

Make training
progress visible.

What has a trainee practised, and what still needs work? Records help mentors hand over and review progress.

  • Training records
  • Feedback and handovers
  • Pilot findings and limits

Making new-personnel training visible

Four trainees at one station produced 797 records over 67 days. The case describes what we learned and why use stopped after the coordinator moved.

Field evidence · English

Seven Days Inside an Ambulance Drug Safe

Seven days of measured storage temperature inside one long-term outdoor-parked ambulance's drug safe: peak 41.4°C, above the 25°C observation threshold 91.1% of the time.

For EMS colleagues and research partners

Questions we can work on together

We can start with a task your crew finds difficult: moving a patient, working in the ambulance or deciding whether a trainee is ready for independent duty.

Field safety problem diagnosis

Describe recurring risks and the conditions in which they occur

For fire, EMS, healthcare, and long-term-care teams facing back injuries from handling, compartment work, equipment and patient securing, training gaps, or high-load care workflows.

Training & competency system design

Set assessment criteria and make records useful for feedback and handovers

For teams reviewing competency criteria, mentor handovers, field checklists and readiness for independent duty.

Field scenario definition & validation

Check products, workflows, and safety assumptions against real frontline use

I help describe how crews use ambulance compartments, handling equipment and prehospital devices, including where a proposed design may be difficult to use on duty.

How I work

I contribute descriptions of field tasks, user needs, likely difficulties and ways to assess a proposed change. Technical partners remain responsible for their technology, regulatory compliance, and maintenance. Project roles and resources should be agreed together. I do not provide procurement endorsements or represent my employing agency.

About

Firefighter, EMS instructor and research contributor

My background in firefighting, EMS education and occupational safety research.

I am a frontline firefighter and EMS instructor in Taiwan. I focus on how crews learn and work under the pressures of shifts, patient care and limited resources.

I draw on field experience and research to develop teaching materials, handling workflows and competency assessment tools. Ambulance compartments are a particular interest: crews must provide care while protecting themselves in a moving workspace.

I distinguish carefully between personal observations, formal research, completed work, and ideas still being explored. Nothing here constitutes an endorsement of any vendor or product.
