Attachment 7_Ductless Heat Pump Safety Data Sheet.pdf

This is a Safety Data Sheet (SDS) for Gasmixture R410A, a refrigerant product manufactured by Ruyuan Dongyanoguang Fluorine Co. Ltd. in Guangdong, China. The document provides comprehensive hazard and safety information according to Federal Register guidelines and GHS-US classification standards.

Gasmixture R410A is classified as a liquefied gas under pressure containing Difluoromethane (R32) at 48.5-50.5% w/w and Pentafluoroethane (R125) at 45.5-51.5% w/w. The product carries a "Warning" signal with hazard statements indicating it contains gas under pressure and may explode if heated. Primary hazards include asphyxiation in high concentrations and potential cold burns or frostbite from liquid contact. The physical state is gas with a boiling point of -51.6°C and vapor pressure of 16.53 bar(a). Storage requirements mandate temperatures below 50°C in well-ventilated locations away from heat and ignition sources, with containers in vertical positions secured against falling. The product is classified as non-flammable with no acute toxicity hazard, though it may cause asphyxiation in high concentrations. For transportation, it is classified as UN3163 liquefied gas under DOT Class 2.2 (non-flammable compressed gas) with quantity limitations of 75 kg for passenger aircraft and 150 kg for cargo aircraft. Both Pentafluoroethane and Difluoromethane components are listed on the United States TSCA inventory and Canadian DSL. Disposal should follow supplier waste gas recovery programs, and environmental precautions emphasize that the product's high volatility makes soil and water pollution unlikely.
