Considerations on disposal
Do not administer anything if patient has fainted
Move to open air. - Administer oxygen or artificial respiration if necessary. - Do not administer adrenaline or similar substances.
Rinse thoroughly with plenty of water for at least 15 minutes and call a doctor.
Wash immediately with plenty of water. - Remove contaminated clothing immediately.
Evacuate personnel to area of safety - Ensure adequate ventilation - Use personal protective equipment
Shut off carefully and keep in a cool, dry and well-ventilated place.
Incompatible products: explosives, inflammable materials, Organic peroxide
For gas recovery and maintenance work in tanks, use an independent breathing apparatus
The vapour is heavier than air and can cause suffocation by reducing the oxygen available for respiration
No reactivity if used in accordance with instructions
Alkaline metals, alkaline-earth metals, granulated metallic salts, Al, Zn, Be, etc. in dust form
Halogenic acids, traces of carbonyl halides, ALC
(R32) LC50/inhalation/4 hours/in rats = 760 l/m
(R125) LC50/inhalation/4 hours/in rats = 800 l/m
Inhalation of vapour at high concentration can produce asphyxiation or cardiac arrhythmia,
irregular pulse, palpitations, reduced circulation and even cardiac arrest.
Has not shown any carcinogenic, teratogenic or mutagenic effects, in experiments performed on animals

Ensure sufficient air changes and/or
use forced ventilation at places of work
Do not breathe vapour or droplets
Keep in original containers.
