Download a free R32 Refrigerant Difluoromethane COSHH assessment for documenting the safe use, handling, storage, recovery and control of R32 refrigerant in the workplace. This editable COSHH assessment template is designed for air conditioning engineers, refrigeration engineers, heat pump installers, facilities managers, maintenance contractors, HVAC companies, service teams, commercial premises, workshops and plant rooms where R32 refrigerant is used in air conditioning, refrigeration or heat pump systems.
R32 Refrigerant, also known as difluoromethane, is a hydrofluorocarbon refrigerant used in many modern air conditioning and heat pump systems. It is commonly classed as an A2L lower flammability refrigerant, meaning it requires careful control during installation, servicing, leak testing, recovery, charging and decommissioning work. Because R32 is a pressurised refrigerant gas and may present flammability, asphyxiation and pressure-related hazards if released, it should be assessed carefully under COSHH and considered alongside DSEAR, F-gas duties and the manufacturer’s safety data sheet.
This R32 Refrigerant Difluoromethane COSHH assessment template helps employers and responsible persons record key product details, intended use, cylinder storage arrangements, charging and recovery methods, exposure controls, ventilation requirements, leak response, fire precautions, emergency procedures, first aid information, environmental controls, PPE requirements, user instructions and review dates. It provides a practical starting point for workplaces needing an R32 refrigerant COSHH assessment, difluoromethane COSHH template, A2L refrigerant safety document, HVAC refrigerant COSHH assessment or free health and safety document template for air conditioning and heat pump refrigerants.
Employers and duty holders have a legal responsibility to assess substances and gases used during work activities and make sure employees, engineers, contractors, building users and others are not exposed to unnecessary health and safety risks. Under the Control of Substances Hazardous to Health Regulations 2002, hazardous substances must be identified, assessed and controlled where required. Because R32 is a pressurised refrigerant gas with flammability considerations, employers should also consider the Dangerous Substances and Explosive Atmospheres Regulations 2002, which require fire and explosion risks from dangerous substances to be assessed and reduced so far as reasonably practicable.
For products such as R32 Refrigerant Difluoromethane, the COSHH assessment should reflect the actual work being carried out, including cylinder handling, connecting gauges and hoses, pressure testing, charging equipment, recovering refrigerant, leak detection, purging lines where appropriate, working in enclosed or poorly ventilated areas, preventing ignition sources, avoiding uncontrolled releases and ensuring only compatible tools and recovery equipment are used. The assessment should also consider emergency ventilation, refrigerant gas detection where required, safe transport and storage of cylinders, prevention of frostbite from liquid contact and the risk of oxygen displacement if refrigerant is released in confined spaces.
Because R32 refrigerant is an F-gas, the assessment should also consider F-gas legal responsibilities. Personnel working on equipment containing F gases must hold the correct qualifications, and companies carrying out work on stationary air conditioning, refrigeration or heat pump equipment for others may require company certification. Suitable arrangements should also be in place for refrigerant leak checks, recovery, record keeping, labelling, recycling, reclaiming or disposal, depending on the system type and work being carried out.
A clear R32 Refrigerant COSHH assessment helps demonstrate that refrigerant handling, A2L flammability controls, gas cylinder storage, leak response, engineer competence, F-gas compliance and environmental protection have been properly considered as part of workplace health and safety management. This is particularly useful for HVAC engineers, air conditioning contractors, refrigeration technicians, heat pump installers, facilities teams, building managers, maintenance supervisors and duty holders responsible for plant rooms, cooling systems, refrigerant storage, contractor control and service documentation.
The document can be customised with your company details, site location, equipment type, refrigerant charge size, cylinder storage area, work activity, authorised users, engineer competence, ventilation arrangements, ignition-source controls, leak response procedures, PPE requirements and review date. Once completed, the assessment can be downloaded as a PDF, stored in your compliance records or shared with engineers, contractors, facilities teams, supervisors and health and safety representatives.
