REFRIGERANT MATERIAL SAFETY DATA SHEET
1) R404a: fluid components
•
trifluoroethane
•
pentafluoroethane
•
tetrafluoroethane
GWP = 3750
ODP = 0
2) Hazard identification
Overexposure through inhalation may cause anaesthetic effects. Acute overexposure may cause cardiac
rhythm disorders and sudden death. Product mists or sprays may cause ice burns of eyes and skin.
3) First aid procedures
•
Inhalation: keep injured person away from exposure, warm and relaxed. Use oxygen, if necessary. Give
artificial respiration if respiration has stopped or is about to stop. In case of cardiac arrest give external
cardiac massage. Seek immediate medical attention.
•
Skin: use water to remove ice from affected areas. Remove contaminated clothes.
CAUTION: clothes may adhere to skin in case of ice burns.
In case of contact with skin, wash with copious quantities of lukewarm water. In case of symptoms
(irritation or blisters) seek medical attention.
•
Eyes: immediately wash with ocular solution or fresh water, keeping eyelids open for at least 10 minutes.
Seek medical attention.
•
Ingestion: it can cause vomit.. If conscious, rinse mouth with water and drink 200-300 ml of water. Seek
medical attention.
Other medical treatment: symptomatic treatment and support therapy when indicated. Do not administer
adrenaline or sympatheticomimetic drugs after exposure, due to the risk of arrhythmia and possible cardiac
arrest.
4) Environmental data
Persistence and degradation
•
HFC 143a: slow decomposition in lower atmosphere (troposphere). Duration in atmosphere is 55 years.
•
HFC 125: slow decomposition in lower atmosphere (troposphere). Duration in atmosphere is 40 years.
•
HFC 134a: relatively rapid decomposition in lower atmosphere (troposphere). Duration in atmosphere is
15.6 years.
•
HFC 143a, 125, 134a: does not affect photochemical smog (not included in volatile organic components
– VOC – as established in the UNECE agreement). Does not cause ozone rarefaction.
Product exhausts released in the atmosphere do not cause long-term water contamination.
