Provides recommendations and information relevant to the health and safety of persons engaged in procedures to be used in the transfer of halon from one container to another.

Abstract

Overview

Key Topics

Scope and Definitions The document defines halons 1211 (difluorochlorobromomethane) and 1301 (trifluorobromomethane) as colorless gases used for fire suppression. It covers procedures applicable to storage containers, fire extinguishers, and transport vessels.
Health and Safety Recommendations Guidelines are provided to protect workers from the toxic and physical hazards of halons, such as:
- Preventing skin contact with liquid halon which can cause frostbite and irritation
- Avoiding inhalation of halon vapors above established exposure limits (1000 ppm over 8 hours)
- Ventilating transfer areas to reduce inhalation risk
- Handling exposure incidents with appropriate medical care and avoiding use of epinephrine due to cardiac risks
Pressure Control and Equipment Safety Emphasis is placed on controlling pressures during transfer operations using nitrogen pressurization with secure pressure relief devices. All components must withstand test pressures at least twice the normal service pressure.
Material Compatibility The standard advises selecting materials compatible with halons to avoid corrosion and contamination, highlighting the need for moisture-free environments to prevent hydrolysis of halons.
Procedures for Safe Transfer and Recovery Two main methods for transferring halon between containers are detailed:
- Transfer by nitrogen overpressure with dry, controlled nitrogen gas
- Pumping with volumetric pumps positioned close to the source container to avoid vapor loss

Recovery operations require separate setups to avoid contamination. Containers must be clean, inspected, leak-free, and clearly labeled to identify contents and contamination status.

Environmental Protection Procedures aim to minimize unnecessary halon release, preventing atmospheric damage related to ozone depletion.

Applications

ISO 7201-2:1991 is essential for organizations and professionals engaged in:

Fire extinguisher manufacturing and maintenance Assures safe refilling and handling of halon-based extinguishers following best practices.
Fire suppression system servicing Enables safe draining, recovery, and recharge of halon in fixed fire protection installations.
Transport and storage of halon containers Provides guidelines for safe transfer during logistics to prevent leaks and exposure.
Environmental compliance Supports businesses and regulatory bodies in implementing procedures aligned with ozone protection and occupational safety regulations.
Occupational safety training Acts as a basis for worker education on hazards and correct handling techniques during halon transfer.

Overall, this standard helps reduce risks associated with toxic exposure, pressure hazards, and environmental contamination during halon handling operations.

Related Standards

ISO 7201-2:1991 complements a series of fire extinguishing media standards within ISO and related organizations, including:

ISO 7201-1:1989 - Specifications for halons 1211 and 1301 Provides detailed product specifications and quality criteria for halon extinguishing agents.
ISO 5923:1989 - Fire protection - Carbon dioxide extinguishing agents Addresses CO2 extinguishers and safe handling practices.
ISO 7202:1987 - Fire protection - Dry powder extinguishing agents Details powder types and usage guidelines.
ISO 7203-1: (under development) - Fire protection - Foam extinguishing agents-Part 1: Low expansion foam Targets specifications and safety for foam fire suppressants.

For facilities storing or working with halons, adherence to ISO 7201-2 along with ISO 7201-1 ensures compliance with international best practices for safety, environmental stewardship, and equipment integrity during fire suppression operations.
