Eye contact
Immediately irrigate with eyewash solution or clean water, holding the eyelids apart, for at
least 10 minutes. Obtain immediate medical attention.
Skin contact
Inh
alation
Ingestion
Notes to p
hysician
5. Fire-fighting measures
Thaw affected areas with water. Remove contaminated clothing. Caution: clothing may
adhere to the skin in the case of freeze burns. After contact with skin, wash
immediately with plenty of warm water. If irritation or blistering occur obtain medical
attention.
Remove patient from exposure, keep warm and at rest. Administer oxygen if
necessary. Apply artificial respiration if breathing has ceased or shows signs of failing.
In the event of cardiac arrest apply external cardiac massage. Obtain immediate
medical attention.
Ingestion is not considered a potential route of exposure. Do not induce vomiting.
Provided the patient is conscious, wash out mouth with water and give 200-300 ml
(half a pint) of water to drink. Obtain immediate medical attention.

Shut off gas supply if this can be done safely. If possible, take container out of
dangerous zone. Cool cylinders with water spray. Self-contained breathing apparatus
(SCBA) may be required if cylinders rupture or release under fire conditions.
Hydrogen fluoride by thermal decomposition and hydrolysis.
Personal precautions Immediately contact emergency personnel. Keep unnecessary personnel away. Use
suitable protective equipment (section 8). Shut off gas supply if this can be done safely.
Isolate area until gas has dispersed.
Environmental precautions
Methods for cleaning up
Prevent liquid from entering drains, sewers, basements and work pits since the vapor
may create a suffocating atmosphere.
Provided it is safe to do so, isolate the source of the leak. Allow small spillages to
evaporate provided there is adequate ventilation. Large spillages: Ventilate area.
Contain spillages with sand, earth or any suitable adsorbent material.
7. Handling and storage
Handling Avoid inhalation of high concentrations of vapors. Atmospheric levels should be
controlled in compliance with the occupational exposure limit. Atmospheric
concentrations well below the occupational exposure limit can be achieved by good
occupational hygiene practice. The vapor is heavier than air, high concentrations may
be produced at low levels where general ventilation is poor, in such cases provide
adequate ventilation or wear suitable respiratory protective equipment with positive air
supply. Avoid contact with naked flames and hot surfaces as corrosive and very toxic

decomposition products can be formed. Avoid contact between the liquid and skin and eyes.
For correct refrigerant composition, systems should be charged using the liquid phase and
not the vapor phase.
Storage Keep in a well ventilated place. Keep in a cool place away from fire risk, direct sunlight and
all sources of heat such as electric and steam radiators. Avoid storing near to the intake of
air conditioning units, boiler units and open drains. Cylinders and Drums:
Keep container dry. Storage temperature: < 45°C

se adequate general or local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
Individual protection measures, such as personal protective equipment:
Eye / face protection
Skin protection
Sufficient eye protection should be worn. When handling compressed gas, at least glasses with
side protection should be worn. When handling liquid gas, chemical safety goggles must be
used as well as a protective shield.
Body protection: Use protective boots while handling gas cylinders.
Hand protection: Wear leather gloves to prevent frostbite injuries from rapidly expanding gas
when handling pressurised gas bottles.
Respiratory protection In an emergency (e.g.: unintentional release of the substance, exceeding the occupational
exposure limit value) respiratory protection must be worn. Consider the maximum period for
wear. Wear self-contained breathing apparatus. Do not use filter respirator.
General hygiene
considerations
Wash hands, forearms and face thoroughly after handling chemical products, before eating,
smoking and using the lavatory and at the end of the working period. Keep away from
foodstuffs, beverages and feed. Immediately remove all soiled and contaminated clothing.
