EN 17446:2021/FprA1

Fire extinguishing systems in commercial kitchens - System design, documentation, and test requirements

This document establishes the minimum requirements applicable to the design, installation, functioning, test and maintenance of fixed automatic fire extinguishing systems for kitchen protection that covers the cooking appliances, the hood, the plenum and the air extract ducts. This document also provides requirements for the construction and components performance as applicable to specific types, designs, sizes and arrangements of pre-engineered kitchen fire-extinguishing systems.
This document does not cover household kitchens or industrial food production equipment.
The detailed test procedures for the plenum and air extract ducts are contained in CEN/TS 17749.
Closed plenum type ventilated ceilings designed similar to standard hoods are included in this document. Open plenum type ventilated ceilings are excluded and require an engineered solution for the plenum protection. Protection for appliances below open or closed plenum ventilated ceilings are included.

Overview

EN 17446:2021/FprA1 is a European standard developed by CEN that specifies the essential requirements for fixed automatic fire extinguishing systems in commercial kitchens. The standard focuses on the design, system documentation, installation, operation, testing, and maintenance of fire suppression systems intended to protect cooking appliances, hoods, plenums, and air extract ducts in professional kitchen environments.

This standard addresses pre-engineered kitchen fire extinguishing systems for commercial use but excludes household kitchens and industrial food production equipment. It ensures uniform safety practices across European countries, enhancing fire protection effectiveness in commercial kitchens.

Key Topics

• System Design
  Requirements for planning fire extinguishing systems specific to commercial kitchen layouts, including coverage of cooking surfaces, hoods, plenums, and ductwork.

• Documentation
  Mandates comprehensive documentation detailing system specifications, installation instructions, and maintenance protocols to ensure transparency and traceability.

• Test Requirements
  Defines standardized testing procedures for system functionality, including hazard simulations, splash tests, and temperature assessments to verify performance under operating conditions.

• Components Performance
  Specifies material and construction requirements for extinguishing agents and system components, ensuring reliability and durability against kitchen hazards.

• Cooking Area Limitations
  Sets size limitations for protected appliance surfaces, such as deep fat fryers, to maintain adequate fire suppression coverage.

• Plenum and Air Extract Duct Protection
  Addresses fixed system protection for closed plenum ventilated ceilings and air extract ducts, distinguishing requirements from open plenums which demand engineered solutions.

• Maintenance and Functioning
  Enforces regular inspection, testing, and upkeep practices to sustain system readiness and compliance with safety standards.

Applications

• Commercial Kitchens
  EN 17446:2021/FprA1 applies primarily to restaurants, hotels, catering facilities, and institutional kitchens where fixed automatic fire extinguishing systems are critical for fire safety.

• Kitchen Ventilation Systems
  Provides guidance for integrating fire suppression with ventilated hoods, plenums, and extraction ducts, ensuring holistic protection across kitchen infrastructure.

• Fire Safety Risk Management
  Assists facility managers and fire safety engineers in selecting, installing, and maintaining compliant suppression systems to minimize fire damage, protect personnel, and meet regulatory requirements.

• System Certification and Compliance
  Enables manufacturers and installers to benchmark systems against recognized European criteria, facilitating market acceptance and legal compliance.

Related Standards

• CEN/TS 17749 – Details test procedures for plenums and air extract ducts, complementing EN 17446's requirements for these components.

• EN 15004 Series – Covers broader fixed firefighting system standards applicable to various sectors, providing a framework that EN 17446 extends specifically for commercial kitchens.

• National Fire Safety Codes – EN 17446 interacts with national building and fire codes within Europe, ensuring that commercial kitchen fire suppression aligns with overarching safety regulations.
