The problem
Electrical-safety records should reflect what was actually done.
Facilities often ask for a single universal electrical-safety report. In practice, the tests that apply, the way they are performed, and the criteria used depend on the equipment, its applied parts, the manufacturer's service information, and the applicable standard.
PBES focuses on inspecting the equipment appropriately for its construction and use, and on producing a record that clearly reflects what was inspected, how, and what the outcome was.
The tests performed and evaluation criteria used may vary based on equipment construction, applied-part classification, manufacturer instructions, applicable standards, facility policy, test condition, and governing requirements.
Common issues
What an electrical-safety inspection may include
Not every check applies to every device. Scope is determined by the equipment and the service agreement.
Visual and physical inspection
Review of the device, enclosure, and accessible parts for damage or wear.
Power cord, plug, strain-relief, and enclosure review
Inspection of cord, plug, connector, and enclosure condition.
Protective-earth or grounding continuity
Continuity testing where applicable to the equipment.
Enclosure or touch current
Measurement where applicable to the equipment.
Patient-leakage testing
Where applicable, based on applied parts and governing procedure.
Applied-part testing
Where applicable, based on the applied-part classification confirmed from equipment markings and documentation.
Functional verification
Appropriate to the device and scope of service.
Documentation of findings and measured results
Identification of failed or questionable equipment and corrective-action recommendations.
Our approach
How PBES handles every service visit.
A disciplined sequence, delivered the same way on every device — so your team gets consistent service and consistent documentation through TESSA.
- Step 01
Document the reported issue
Capture symptoms, error codes, history, and how the problem is affecting the workflow.
- Step 02
Identify equipment and asset details
Confirm make, model, serial, and control number so the record ties back to the right device.
- Step 03
Inspect and test the device
Visual inspection plus operational testing appropriate for the equipment and reported issue.
- Step 04
Troubleshoot the likely cause
Based on manufacturer guidance and service findings, isolate the probable cause or next step.
- Step 05
Perform service, PM, or recommendation
Adjustments, cleaning, wear-part replacement, or clear repair recommendations when parts and scope allow.
- Step 06
Verify operation and document in TESSA
Post-service verification and a clean written report you can hand to an administrator or surveyor.
TESSA · The PBES advantage
How PBES documents the work
PBES records the equipment inspected, test or inspection performed, measured results where applicable, findings, outcome, and corrective action. Documentation varies according to the equipment, service scope, and customer requirements.
TESSA — Technical Equipment Support and Service Assistant — is how PBES organizes equipment records, service history, PM status, and repair follow-up for the facilities we serve.
- Equipment identification tied to service records
- Test or inspection performed and applicable evaluation criteria
- Measured results where relevant to the test
- Findings and corrective action captured on the record
- Multi-site visibility for administrators
- Records available on request
Documentation
Clear documentation after every service visit.
TESSA helps PBES produce clean, consistent service documentation — the record your administrators, biomed program, and surveyors expect to see.
- Equipment identification (make, model, serial)
- Location and department
- Inspection or test performed
- Test conditions where relevant
- Measured results where applicable
- Applicable evaluation criteria
- Findings and pass/fail or service outcome
- Corrective action and technician / date

Frequently asked questions.
What does a PBES electrical-safety inspection cover?
Scope depends on the equipment and the service agreement. An inspection may include visual and physical review, power cord and enclosure review, protective-earth or grounding continuity, enclosure or touch current, patient leakage, applied-part testing, and functional verification — as applicable to the device.
Does PBES use one universal set of limits?
No. The tests performed and evaluation criteria used may vary based on equipment construction, applied-part classification, manufacturer instructions, applicable standards, facility policy, test condition, and governing requirements.
How does PBES determine whether a device has a BF or CF applied part?
The applied-part classification is confirmed from equipment markings, manufacturer documentation, service information, and the governing test procedure. The device name alone does not determine the classification.
What happens when testing identifies a problem?
Equipment with an unacceptable result or unsafe physical condition is documented and managed according to the finding, facility policy, and service scope. This may include removing the device from clinical use, repair, additional evaluation, retesting, replacement, or retirement.
Do PBES records satisfy every surveyor or accreditor?
PBES produces documentation of what was inspected, how, and what the outcome was. Whether a facility's overall program meets a specific surveyor or accreditor requirement depends on the facility's program, adopted codes, and authority having jurisdiction. PBES does not certify facility compliance.
Which facilities does PBES support?
PBES supports outpatient healthcare organizations including ambulatory surgery centers, physician practices, community health centers, diagnostic facilities, laboratories, and other applicable care environments. Requirements can vary between facility types.
Where can I learn more about how electrical-safety testing works?
