This a description has told by a safety designer for NASCAR for a land based ambulances.
The vehicle that is suppost to bring lifesaving personnel and equipment to the scene and transport patients to medical treatment could kill everyone in the treatment area in a accident.
While I was attending the fire and rescue convention recently in Ocean City. Maryland, early morning a ambulance transporting a patient to the hospital avoided a deer and crashed into a tree ripping the rightside wall off the unit throwing a paramedic and the patient out of the vehicle killing them. Two others were injuried.
That afternoon I attended a seminar on ambulance safety about safety for the attendants and patients.
The seminar was conducted by a medical doctor of pediatrics who has open many eyes about the way ambulances are built much of it is not federally regulated for safety.
Crash test are not conducted on ambulance bodies unless done by independent safety groups.
Cabinets inside can injure attendents or patients when they strike them in a accident or items are thrown out of them.
Seating is not set for treatment of patients so the attendant has to remove their seatbelt to be close to the patient to do treatment.
Bench seating along the wall only has lap belts which could cause injury or death.
Equipment may not be secured.
We as attendants have been told we may have to wear helmets designed for ambulance work and be worn from dispatch until return to quarters.
There were many more ideas and questions about this.
To check it out http://www.objectivesafety.net you can see other seminars under handouts and safety info about this.
I have even found on youtube ambulance crash test that could curl peoples hair.
