Understanding BS9999 and EN50171: Legal Standards, Evacuation Lifts, Booster Pumps, Emergency Lighting, and Key Considerations When Purchasing

Date

Ensuring fire safety and emergency preparedness in buildings requires strict adherence to standards like BS9999 and EN50171. These standards provide the necessary framework to guarantee that safety systems operate reliably during emergencies. Among the critical systems covered are evacuation lifts, booster pumps, and emergency lighting.

What is BS9999?

BS9999 is a British Standard offering guidance on fire safety in the design, management, and use of buildings. It employs a risk-based approach, providing a flexible framework that adapts to different building types and uses.

Key Points of BS9999:

  • Risk-Based Approach: Tailors fire safety solutions to each building’s unique risk profile.
  • Design Flexibility: Allows for innovative design while maintaining safety.
  • Fire Protection Measures: Includes guidelines for fire alarms, emergency lighting, smoke control, evacuation procedures, and systems like evacuation lifts and booster pumps.
  • Management Strategies: Highlights the importance of ongoing fire safety management, including regular training, drills, and maintenance.

What is EN50171?

EN50171 is a European standard detailing the requirements for central power supply systems (CPSS) used in emergency systems, including emergency lighting, fire safety systems, and other critical equipment. These systems ensure that essential safety features remain operational during power failures.

Key Points of EN50171:

  • Continuous Power Supply: Ensures safety systems function during power outages.
  • System Reliability: Sets stringent requirements for the reliability and performance of CPSS.
  • Testing and Maintenance: Requires regular testing and maintenance to ensure systems are always ready for emergencies.
  • Compatibility with Safety Systems: Ensures CPSS can support various safety systems, including emergency lighting and evacuation lifts.

The Role of Evacuation Lifts in BS9999

Evacuation lifts are designed for use during emergencies, such as fires, to evacuate people, including those with mobility impairments. Unlike standard lifts, evacuation lifts are built to operate safely even during a fire.

Key Points on Evacuation Lifts in BS9999:

  • Safe Use During Emergencies: BS9999 permits the use of evacuation lifts if they meet strict safety criteria, ensuring reliable operation under fire conditions.
  • Fire Resistance: The lift shaft and lobby must be highly fire-resistant to protect against heat and smoke.
  • Power Supply: Evacuation lifts must be connected to a reliable power source, often backed by an EN50171-compliant CPSS.
  • Communication Systems: Should include communication tools to connect occupants with emergency services.
  • Management and Training: Staff must be trained to assist with the use of evacuation lifts during an emergency.

Booster Pumps and BS9999

Booster pumps play a critical role in a building’s fire protection system by ensuring adequate water pressure for firefighting. These pumps are essential in taller buildings or large complexes where mains water pressure may be insufficient.

Key Points on Booster Pumps in BS9999:

  • Water Supply Integrity: Booster pumps ensure fire suppression systems, such as sprinklers, receive adequate water pressure.
  • Reliable Operation: Pumps must be reliable, with backup power sources to ensure they remain operational during power outages.
  • Maintenance and Testing: Regular maintenance and testing are required to keep booster pumps in working order.
  • System Integration: Booster pumps must be integrated into the overall fire protection system, ensuring seamless operation during emergencies.

Emergency Lighting and EN50171

Emergency lighting is vital for safe evacuation during power outages. EN50171 covers the requirements for central power supply systems that support emergency lighting, ensuring it functions reliably during an emergency.

Key Points on Emergency Lighting in BS9999 and EN50171:

  • Compliance with EN50171: Emergency lighting systems must be supported by a reliable CPSS to ensure continuous operation during power failures.
  • Illumination Standards: BS9999 specifies the required level and duration of illumination to guide occupants safely out of the building.
  • System Reliability: Emergency lighting must undergo regular testing and maintenance to ensure it is always operational when needed.
  • Strategic Placement: Lights should be strategically placed to illuminate exits, stairwells, and other critical areas.

What to Look for When Buying BS9999, EN50171-Compliant Products, and Related Safety Equipment

When purchasing products or systems that must comply with BS9999 and EN50171, including evacuation lifts, booster pumps, and emergency lighting, consider the following:

  • Certification and Compliance: Ensure all products are certified as compliant with BS9999 and EN50171. For evacuation lifts, booster pumps, and emergency lighting, verify that they meet the specific criteria outlined in these standards.
  • Product Reliability: Choose products with a proven track record of reliability, especially for critical systems like evacuation lifts and booster pumps. Reliable operation during emergencies is essential.
  • Compatibility: Ensure that all systems, including evacuation lifts and booster pumps, are compatible with your building’s existing safety infrastructure, such as fire alarms and emergency lighting.
  • Maintenance and Support: Select systems that offer comprehensive maintenance and support services. Regular maintenance is crucial, particularly for evacuation lifts, booster pumps, and emergency lighting systems, to ensure they are always ready for use.
  • Supplier Reputation: Work with suppliers known for their expertise in fire safety and emergency systems. Their experience can help you select the right products and ensure full compliance with all standards.
  • Safety vs. Cost: While cost is always a factor, the safety of building occupants should take precedence. Investing in high-quality, compliant systems—especially for evacuation lifts, booster pumps, and emergency lighting—can prevent costly legal consequences and, more importantly, save lives.

The Critical Role of Emergency Power Supply in Adhering to BS9999 and EN50171

A reliable emergency power supply is the backbone of adherence to both BS9999 and EN50171. It ensures that critical safety systems, including evacuation lifts, booster pumps, and emergency lighting, remain operational during power outages—an essential requirement for maintaining safety and compliance.

How Emergency Power Supply Supports Compliance:

  • Continuous Operation: During an emergency, particularly a fire, power outages are common. An EN50171-compliant central power supply system ensures that essential safety equipment continues to function, supporting the evacuation process and firefighting efforts.
  • Enhanced Reliability: With a robust emergency power supply, the risk of critical systems failing during an emergency is significantly reduced, enhancing the overall safety of the building.
  • Regulatory Compliance: By providing continuous power to evacuation lifts, booster pumps, and emergency lighting, an emergency power supply helps ensure that your building remains compliant with BS9999 and EN50171, avoiding legal repercussions and ensuring the safety of all occupants.

In conclusion, the integration of a reliable emergency power supply is not just beneficial but essential for meeting the stringent requirements of BS9999 and EN50171. It ensures that all critical safety systems remain functional during emergencies, ultimately safeguarding lives and supporting compliance with legal standards.
