Updated Risk Assessment

Risk Category Severity (1-9) Likelihood (1-9) Importance (1-81) Triggers Mitigation Plan

Equipment fails Safety 8 6 48

Power is not supplied to the equipment, equipment does not have a long life span and stops working during transport Educate university students in Honduras to upkeep equipment to prevent failures

Injuries to infants resulting from transport Safety 9 5 45

Securements of infants in incubator are not sufficient, bad roads in Honduras loosen the securements Provide adequate infant securements in incubator, thoroughly test securements in packaging lab to simulate transport

Medical professional is not secured during transit Safety 7 6 42

Seat belt becomes unbuckled during transport, seat belt is hit by object or hand, seat belt not worn Provide adequate way to comfortably secure medical professional in the proper seat.

Equipment needed is not present during transport Technical 8 5 40

Unexpected circumstances require equipment not on board,all equipment needed is not accounted for during planning Ask doctors what equipment they want present. Survey U.S. ambulances for the equipment commonly used

Incubator becomes unsecured during transport Safety 9 4 36 Latches are not used, latches become loose

due to bad roads or other situations Test custom securements adequately in packaging lab

Power output is not pure sine wave Technical 9 4 36 Power output is wrong (ex. square wave)

Use medical grade inverter that outputs pure sine wave

Equipment is not sterile Safety 4 8 32 Incubator or other equipment that must be

cleaned between infants is not Provide bleach, ethanol, and other cleaning

  • equipment. Easily accessible after each transport

event

Monitoring equipment is not accurate Technical/ Safety 7 4 28

Monitoring equipment has too large of percent error, monitoring equipment does not read neonate signals (typically smaller than adult) Ensure neonate compatible monitor for small signals readings and sensors

Vehicle crashed/flips Safety 9 3 27 Bad roads and top heavy design

N/A

Vehicle is designed to be top heavy Safety 9 3 27 Storage is put up high and not distributed well

Make sure storage and weight is allocated well as to prevent vehicle from being top heavy
