Disasters, Water and Power Failures, and Communication
Key Takeaways
- Emergency preparedness covers disasters, evacuation, sheltering, communication, supplies, utilities, and continuity of dialysis care.
- Water or power failure can make dialysis unsafe, so technicians must follow emergency procedures and notify appropriate staff immediately.
- Patients need clear instructions during emergencies, but technicians should stay within role and use approved facility messages.
- Communication during infection-control or safety events should be timely, factual, confidential, and directed to the correct chain of command.
Preparedness mindset
Dialysis patients depend on reliable treatment schedules, safe water, working power, supplies, transportation, and communication. Disasters can disrupt all of these. Preparedness means knowing the facility plan before an event occurs.
Common events include severe weather, earthquake, flood, fire, power outage, water interruption, boil-water advisory, water treatment alarm, supply shortage, cyber or phone outage, and community emergency. The technician should know where emergency policies, contacts, supplies, and evacuation routes are located.
Water and power failures
Hemodialysis requires safe water and functioning equipment. If water pressure fails, treated water alarms occur, power fails, or the machine cannot operate safely, the technician should follow facility emergency procedure and notify the RN, charge nurse, biomedical staff, or supervisor as directed.
Do not start treatment when required water, dialysate, electrical, or safety checks cannot be completed. Do not silence or ignore utility-related alarms to keep the schedule moving. Patient safety and system integrity come before throughput.
Disaster actions
During a disaster, technicians may assist with calming patients, maintaining clear paths, gathering emergency supplies, helping with emergency disconnect or evacuation as trained, documenting events, and communicating patient status to the team. Facility leadership directs evacuation, sheltering, closure, or transfer decisions.
Patients may ask where to go for the next treatment. Use approved facility instructions. Do not invent schedules, promise availability, or provide medical advice beyond role. If a patient reports inability to travel, loss of power at home, shortness of breath, missed treatments, or unsafe conditions, report promptly.
Communication and confidentiality
Safety communication should be concise and factual: what happened, who is affected, what immediate action was taken, what equipment or area is involved, and what help is needed. Include time and location when reporting. Document according to policy.
Infection-control communication must protect privacy. Report exposures, isolation needs, vaccination concerns, spill events, waste problems, and cleaning failures to the appropriate staff. Do not discuss diagnoses in public areas or with people who do not need the information for care.
| Event | Technician priority |
|---|---|
| Water treatment alarm | Notify appropriate staff and follow stop/start policy |
| Power outage | Follow emergency procedure and protect connected patients |
| Severe weather closure question | Use approved facility communication |
| Exposure to blood splash | Perform first aid steps by policy and report immediately |
On the exam, the safest answer is rarely to improvise. Recognize the hazard, protect patients, follow the plan, and communicate through the chain of command.
A water treatment alarm sounds before a patient is connected. What should the technician do?
During a power outage, what is the technician's best role?
A patient asks whether another patient is in isolation for hepatitis. What should the technician say?
