JRAIA: Top Issue #3:Continue further risk assessmentRisk assessment of A3 refrigerants( for small AC or Built-in Refrigerator)

■ Direction・In the trend of deregulation of A3 refrigerants, JRAIA will propose air-conditioner be secured.・Based on RAC's risk assessment method and results for A2L refrigerant , JRAIA also conducts risk assessment

for A3 refrigerant and recommended measures to ensure safety from the evaluated result.・JRAIA collaborates with universities and research institutions to compare the hazards tothe refrigerant of A2L and A3 refrigerants.

■ Schedule・First year ; A3 refrigerant risk assessment ・Second year ; Estimation method and make plan for risk reduction・ Last year ; Making practical measures and verifying by risk assessment
