Warnings Regarding Potentially Toxic Substances; First-Aid Measures - RHOSS TCCE 135 Gebrauchsanweisung

I.1.5 WARNINGS REGARDING POTENTIALLY
TOXIC SUBSTANCES
DANGER!
Read carefully the following information about the
refrigerants employed.
I.1.5.1 Identification of the type of refrigerant used
• Difluoromethane (HFC32) 23% by weight
CAS No. 000075-10-5 000075-10-5
• Pentafluoroethane (HFC125) 25% by weight
CAS No. 000354-33-6 000354-33-6
• 1, 1, 1, 2 - Tetrafluoroethane (HFC134a) 52% by weight
CAS No. 000811-97-2 000811-97-2
I.1.5.2 Identification of type of oil used
The type of lubricant used in the unit is polyester oil, however in all
cases refer to the indications which are to be found on the compressor
data plate.
DANGER!
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.
I.1.5.3 Main ecological information regarding the
types of refrigerant used
ENVIRONMENTAL SAFEGUARD
Read carefully the ecological information and the
following directions.
• Persistence and degradation
Decomposes with relative rapidity in the lower atmosphere
(troposphere). Decomposition by-products are highly dispersible and
thus have a very low concentration. They have no influence on
photochemical smog (that is, they are not classified among VOC volatile
organic compounds, according to the guidelines established by the
UNECE agreement). Fluids R32, R125 and R134a (contained in all the
units) do not damage the ozone layer. These substances are regulated
by the Montreal Protocol (1992 Revision) and by CE Regulation N°
2037/2000 dated 29 June 2000.
• Effects on effluent treatment
Waste products released into the atmosphere do not produce long-term
water contamination.
• Individual protection/exposure
Wear protective clothing and suitable gloves. Protect the eyes and face.
• Professional exposure limits:
R407
HFC 32 TWA 1000 ppm
HFC 125 TWA 1000 ppm
HFC 134a TWA 1000 ppm – 4240 mg/m
• Handling
DANGER!
User and maintenance personnel must be
adequately informed about the risks of handling
potentially toxic substances. Failure to observe the
above precautions may cause personal injury or
damage to the unit.
Avoid inhalation of high concentrations of vapour.
Atmospheric concentration must be reduced to a minimum and
maintained at this minimum level, well beneath professional exposure
limits. Vapour is heavier than air, and thus hazardous concentrations
may form close to the floor, where overall ventilation may be poor. In
these cases, ensure adequate ventilation. Avoid contact with open
flames and hot surfaces, which could lead to the formation of irritating
and toxic products of decomposition. Do not allow the liquid to come
into contact with eyes or skin.

• Procedure in case of accidental refrigerant escape
Ensure adequate personal protection (using means of respiratory
protection) during clean-up operations. If the conditions are sufficiently
safe, isolate the source of leak. If the amount of the spillage is limited,
allow the material to evaporate but make sure that ventilation is
adequate . If the spill is considerable, ventilate the area adequately.
Contain the spilt material with sand, soil, or other suitable non-
absorbent material. Prevent the liquid from entering discharge pipes,
drains, sewers, underground facilities or manholes in the working area;
because suffocating vapours may form.
I.1.5.4 General toxicological information on type of
refrigerant used
• Inhalation
A high atmospheric concentration can cause anaesthetic effects with
possible loss of consciousness. Prolonged exposure may lead to
irregular heartbeat and cause sudden death.
Higher concentrations may cause asphyxia due to the reduced oxygen
level in the atmosphere.
• Contact with skin
Splashes of nebulized liquid can produce frostbite. It is probably not
hazardous if absorbed through the skin. Repeated or prolonged contact
may remove the skin's natural oils, with consequent dryness, cracking
and dermatitis.
• Contact with eyes
Splashing liquid may cause frostbite.
• Ingestion
While highly improbable, it may produce frostbite.
I.1.5.5 First aid measures
DANGER!
Adhere scrupulously to the warnings and first aid
procedures indicated below.
• Inhalation
Move the person away from the exposure area, keep him warm and let
him rest. Administer oxygen if necessary. Attempt artificial respiration if
breathing has stopped or shows signs of stopping. If the heart stops,
perform external heart massage. Seek medical assistance.
• Contact with skin
In case of contact with skin, wash immediately with lukewarm water.
Thaw tissue using water. Remove contaminated clothing. Clothing may
stick to the skin in case of frostbite. If irritation, swelling or blisters
appear, seek medical assistance.
• Contact with eyes
Rinse immediately using an eyewash or clean water, keeping eyelids
open, for at least ten minutes. Seek medical assistance.
• Ingestion
Do not induce vomiting. If the injured person is conscious, rinse his/her
mouth with water and make him/her drink 200-300 ml of water. Seek
immediate medical assistance.
• Further medical treatment
Treat symptoms and carry out support therapy as indicated. Do not
administer adrenaline or similar sympathomimetic drugs following
exposure, due to the risk of cardiac arrhythmia.
