Your comprehensive guide to the key components of well-designed and prepared electrical healthcare systems.
There may be no more critical environment for continuous electrical power than a healthcare facility. Uninterrupted functioning of everything from heart monitors to HVAC systems helps ensure patient safety and the success of critical medical procedures.
The opposite scenario can mean delayed treatments, malfunctioning machines, or injury and death. This article will provide practical, actionable insights into the design, implementation, and maintenance of reliable and robust electrical healthcare systems.
Engineers and facility administrators will also learn best practices toward ensuring their infrastructure stays reliable and compliant.
Key Takeaways:
- Uninterruptible power supply (UPS), generators, and automatic transfer switches (ATS) are some core components of a robust electrical healthcare system
- Compliance with all necessary local, state, and national electrical codes is key to successful and ongoing operations
- Healthcare staff can be invaluable resources toward a safer electrical environment
UPS Systems
These provide near-instantaneous backup power in case of grid failure, which helps ensure that critical systems and operations can continue during outages.
UPS systems also protect against power surges, voltage sags and spikes, and electrical disturbances that impact power quality. A UPS will stabilize all of these to protect sensitive medical equipment.
UPS units come in two types, with online/double-conversion models providing the highest quality of power for critical data servers, intensive care units (ICUs), and surgical suites. Line-interactive models are best suited to non-critical medical areas where concerns over power fluctuations are less pronounced.
Choosing the right UPS is imperative. It’s even better if you have seasoned electrical experts design UPS units tailored specifically to your site’s needs.
Emergency Generators
Power outages can sometimes be prolonged, requiring a powerful and stable source of backup electricity to see hospitals and clinics through extended downtime. This is where generators are so crucial to electrical healthcare systems.
We have firsthand experience in handling every aspect of helping healthcare facilities install multiple emergency generators to guard against the worst outcomes. They’re something no medical site should be without.
Furthermore, many federal and state regulations require hospitals to install and regularly maintain their backup generators or face steep fines, regulatory action, or closure.
Natural gas generators provide a steady fuel supply but are vulnerable to natural disasters. Diesel generators offer high power, fuel efficiency, and reliability preferable for hospitals.
Other important factors to consider are:
- The site’s square footage
- The generator’s required kilowatt output
- The site’s current monthly power usage
- Ideal generator placement
Whichever design you choose, always prioritize generator safety steps to protect everyone who interacts with it.
ATS
As the name suggests, these automatically and seamlessly switch between primary and secondary power backups. As an example, think of them as the intermediary between a failed grid and your waiting generator.
Maintaining ATS is made easier when they’re integrated with a building management system, allowing for centralized power monitoring.
Centralized power also allows for easier monitoring and maintenance of other critical electrical healthcare systems like HVAC, smoke and fire detection, and water management.
Hospital facility managers are further empowered by ATS through remote monitoring, allowing them to activate or shut off power connections and to identify and solve power issues before failures occur.
Design and Implementation Strategies
The first step to creating best-fit electrical healthcare systems is conducting a comprehensive power needs assessment. This provides key insights like:
- Evaluation of the Site’s Critical Loads
Critical loads are those systems and equipment that are essential to safe operations and require uninterrupted power. These include emergency rooms, medical imaging areas, surgical suites, and ICUs. - Scalability Considerations
Medical facilities must consider future expansion when designing their electrical systems. New equipment or additional square footage will increase the site’s energy demands, so any potential growth must be factored into the infrastructure. - Redundancy, System Architecture, and Segregation of Power Sources
Single points of failure can be avoided by having multiple backup power sources of various types to protect and provide for critical loads. Dual power feeds into critical areas like surgery also provide fail-safes against one feed failing.By National Electrical Code (NEC) requirements, electrical healthcare systems must be segregated by function into three separate categories: equipment, critical, and safety. Each group must have its own set of switches and power sources.
Following NEC requirements must be complemented by adhering to those of the International Electrotechnical Commission (IEC) and the National Fire Protection Association (NFPA).
Compliance with Other Standards and Regulations
IEC compliance focuses on the performance and safety of medical electrical equipment under IEC 60601, while NFPA compliance encompasses:
- Electrical safety, emergency power, and risk management under NFPA 99
- Emergency and standby power systems, ensuring hospitals have reliable backup power under NFPA 110
Maintenance and testing protocols are often central aspects of electrical compliance. Electrical healthcare systems must be regularly tested and maintained to ensure reliable performance.
Electrical inspections are also essential in gauging the condition of these systems and identifying any current or potential issues.
Systems can be tested by conducting simulated power outage drills to see how quickly and efficiently backup power is engaged. Generators can also be load-tested under simulated conditions to check if they can handle their responsibilities.
All equipment must be regularly serviced to test wiring, to test connections, and to monitor the battery health of system units like UPS.
Staff Training and Preparedness
Healthcare staff are also an integral part of a safe, operational site. Staff must be informed and proficient about operating backup systems, spotting problems, and troubleshooting to the best of their abilities (before calling the professionals is required).
Creating a workplace electrical safety program will give staff the skills and confidence they need to follow safety protocols and emergency procedures in various power-related scenarios.
