| 1 | Electrical System Capacity | Confirm that the alternator, auxiliary battery, inverter, outlets, and wiring can support all installed medical, rescue, and communication devices. | Compare the vehicle's continuous and peak electrical output with the combined operating and startup loads of the equipment. Check whether the system uses a 12 V or 24 V architecture. | Request a load calculation, inspect circuit protection, and test the system with all critical devices operating simultaneously. | High |
| 2 | Medical Equipment Mounting | Evaluate mounting points for stretchers, oxygen cylinders, monitors, defibrillators, suction units, and medication storage. | Mounts should be mechanically secure, accessible during patient care, and suitable for the equipment's dimensions and weight. Restraints must prevent movement during sudden braking or collision. | Measure cabinet and floor clearances, verify load ratings, and inspect locking mechanisms and retention straps. | High |
| 3 | Oxygen and Medical Gas Integration | Check cylinder storage, medical gas outlets, pressure regulators, ventilation, and separation from heat or ignition sources. | Use compatible cylinders, regulators, tubing, and connectors. Oxygen storage must be secured and protected from impact, contamination, and excessive heat. | Review the gas-system schematic, inspect cylinder restraints, and conduct leak and pressure tests according to applicable local requirements. | High |
| 4 | Rescue Tool Storage | Assess storage for hydraulic rescue tools, battery tools, cutting equipment, ropes, fire extinguishers, helmets, and personal protective equipment. | Storage compartments should support the tool weight, resist vibration, allow drainage where needed, and provide rapid access without blocking patient-care pathways. | Perform a physical fit test with the largest tools, verify compartment load ratings, and check door operation while the vehicle is parked on a slope. | High |
| 5 | Communication Equipment | Verify space, power, antenna routing, grounding, and control access for radios, satellite terminals, public-address systems, and data devices. | Confirm the required frequency bands, connector types, antenna locations, transmission power, and separation from sensitive medical electronics. | Conduct an interference test with medical devices running, measure radio coverage in the operating area, and confirm that antennas do not obstruct emergency lighting. | High |
| 6 | Interior Environment and Hygiene | Check ventilation, temperature control, lighting, noise, cleanable surfaces, and infection-control provisions. | Interior materials should tolerate routine cleaning and disinfecting. Equipment placement should preserve an unobstructed aisle and maintain access to the patient from the required working positions. | Inspect seams and surfaces, test lighting and ventilation, and confirm that cleaning agents recommended for the equipment are compatible with interior materials. | Medium |
| 7 | Safety, Standards, and Serviceability | Review crash protection, emergency exits, warning systems, seat restraints, documentation, maintenance access, and replacement-part availability. | The vehicle and installed equipment should comply with applicable road, electrical, occupational-safety, medical-device, and radio regulations in the operating jurisdiction. | Request conformity documents, wiring diagrams, maintenance schedules, inspection records, operator training materials, and a warranty support plan. | Essential |
