SIST EN 2:1995

Overview

SIST EN 2:1995 is a crucial European standard published by CEN that provides a clear and practical classification system for different types of fires. This document categorizes fires into four main classes based on the nature of the fuel involved. The classification is designed to support effective fire fighting and prevention strategies, especially when selecting the appropriate fire extinguishing methods and equipment.

Understanding the classification of fires under SIST EN 2:1995 helps safety professionals, fire fighters, and facility managers to quickly identify fire types and implement the most effective response measures. This standard serves as a foundational guideline in fire safety and emergency preparedness across various industries and settings.

Key Topics

• Fire Classification System
  SIST EN 2:1995 defines four categories of fires, each related to the fuel source:

  • Class A: Fires involving solid materials such as wood, paper, or textiles
  • Class B: Fires involving flammable liquids like petrol, oils, or solvents
  • Class C: Fires involving gases such as propane, butane, or natural gas
  • Class D: Fires involving combustible metals such as magnesium, sodium, or aluminium

• Fuel Nature and Fire Behavior
  The standard emphasizes the importance of understanding fuel characteristics to determine how fires develop and propagate, which is critical for effective extinguishing.

• Extinguishing Methods Alignment
  EN 2 promotes compatibility between fire classification and the selection of extinguishers, making it easier to choose the right extinguisher for the fire type. For example, water extinguishers are effective on Class A fires but inappropriate for Class B or D fires.

Applications

• Fire Fighting Operations
  This classification guides emergency responders in choosing the correct firefighting techniques and equipment, preventing ineffective or hazardous interventions.

• Fire Extinguisher Design & Labeling
  Manufacturers use EN 2 categories to design and label extinguishers clearly, ensuring easy identification and proper use by end-users.

• Workplace Safety Planning
  Facilities develop fire safety plans and training programs based on this classification, improving risk assessment and emergency preparedness.

• Training and Education
  Fire safety training leverages the classification to teach personnel about different fire hazards and appropriate response strategies.

• Insurance and Compliance
  Compliance with EN 2 supports insurance policies and legal regulations related to fire safety standards in commercial and industrial environments.

Related Standards

• EN 3 - Portable Fire Extinguishers
  Specifies requirements for fire extinguishers that correspond to the fire classes outlined in EN 2.

• ISO 11602 - Fire Fighting Equipment
  Provides additional guidance on firefighting equipment design and performance.

• EN 54 - Fire Detection and Alarm Systems
  Complementary standards addressing fire detection and alarm systems for comprehensive fire safety.

• National and Regional Fire Safety Regulations
  EN 2 often aligns with or supports various local fire safety codes and legislation in European countries and beyond.

By adhering to SIST EN 2:1995 fire classification, professionals ensure accurate identification of fire types and enhance the safety and efficiency of firefighting efforts. This standard remains essential for industries seeking to maintain robust fire prevention and response systems.
