Safety; Warning Re Potentially Hazardous Toxic Substances; Refrigerant Handling - Immergas FH 25WZ Instruction And Warning Book

2. SAFETY

2.1 Warning re potentially hazardous toxic substances

2.1.1 Identification of the Type of Refrigerant Fluid Used:
Tetrafluoroethane (HFC134a) 100% by weight CAS No.: 000811-97-2
2.1.2 Identification of the Type of Oil Used.
The lubricant used is polyester oil. Please refer to the information provided on the compressor data plate.
For further information regarding the characteristics of the refrigerant and oil used, refer to the safety data sheets available from
the refrigerant and oil manufacturers.
Main Ecological Information Regarding the Types of refrigerants Fluids used.
ENVIRONMENTAL PROTECTION : Read the ecological information and the following instructions carefully.
2.1.3 Persistence and degradation
The refrigerants used decompose in the lower atmosphere (troposphere) relatively quickly. The decomposed products are highly dispersible and therefore
have a very low concentration. They do not influence the photochemical smog which is not among the VOC volatile organic compounds (as stipulated in the
guidelines to the UNECE). The constituent refrigerants of R407C (R32, R125 and R134a), do not damage the ozone layer. These substances are regulated
under the Montreal Protocol (revised 1992) and regulations EC no. 2037/200 of 29 June 2000.
2.1.4 Effects of discharges
Discharges into the atmosphere of this product does not cause a long-term contamination.
2.1.5 Exposure controls and personal protection
Wear protective clothing and gloves, protect your eyes and face
2.1.6 Professional exposure limits
R134A
HFC-134a TWA 1000 ppm

2.2 Refrigerant handling

Users and maintenance personnel must be adequately informed about the possible risks of handling potentially toxic substan-
ces. Failure to follow such instructions can cause damage to personnel or to the unit.
2.3 Prevent inhalation of high vapor concentration
Atmospheric concentrations of refrigerant must be minimized and kept to a level that is below the occupational exposure limit. Vapor is heavier than air
and can form dangerous concentrations near the ground where the ventilation rate is lower. Always ensure adequate ventilation. Avoid contact with open
flames and hot surfaces as this can cause toxic and irritating decomposition products to form. Avoid contact between liquid refrigerant and the eyes or skin.
