First-aid measures
Description of first aid measures
Immediately remove contaminated clothing. If danger of loss of consciousness, place patient in
recovery position and transport accordingly. Apply artificial respiration if necessary. First aid personnel
should pay attention to their own safety.
If inhaled:
Keep patient calm, remove to fresh air, seek medical attention.
On skin contact:
Flush with copious amounts of water for at least 15 minutes. Immediate medical attention required.
On contact with eyes:
Immediately wash affected eyes for at least 15 minutes under running water with eyelids held open,
consult an eye specialist.
On ingestion:
Immediately rinse mouth and then drink plenty of water, do not induce vomiting, seek medical
attention.
Most important symptoms and effects, both acute and delayed
Indication of any immediate medical attention and special treatment needed
Treatment: Treat according to symptoms (decontamination, vital functions), no known specific
antidote, administer corticosteroid dose aerosol to prevent pulmonary odema
Fire-fighting measures
Extinguishing media
Suitable extinguishing media:
carbon dioxide, dry powder, water spray, foam
Special hazards arising from the substance or mixture
Risk of violent self-polymerization if overheated in a container.
Advice for fire-fighters
Special protective equipment:
Wear a self-contained breathing apparatus.
Further information:
In case of a fire in the vicinity a restabilization system should be used if the temperature in the storage
container reaches 45°C. Evacuate area of all unnecessary personnel. In case of a fire in the vicinity
evacuate all personnel in a greater area if the temperature in the storage container reaches 60°C.
Accidental release measures
Personal precautions, protective equipment and emergency procedures
Take appropriate protective measures.
Ensure adequate ventilation. Use personal protective clothing. Breathing protection
required.
Environmental precautions
Do not discharge into drains/surface waters/groundwater. Contain contaminated water/firefighting
water.
Methods and material for containment and cleaning up
For large amounts: Pump off product. Dispose of absorbed material in accordance with regulations.
For residues: Pick up with suitable absorbent material. Dispose of absorbed material in accordance
with regulations.
Clean contaminated floors and objects thoroughly with water and detergents, observing environmental
regulations.
Handling and storage
Precautions for safe handling
Handle in accordance with good industrial hygiene and safety practice. The substance/ product may
be handled only by appropriately trained personnel. Facility parts must be checked for polymer
residues and cleaned on regular basis in order to avoid hazardous reactions.
Ensure thorough ventilation of stores and work areas. Encapsulation or exhaust ventilation required.
When filling, transferring, or emptying of containers, adequate local exhaust ventilation is necessary.
Vent waste air to atmosphere only through suitable separators. Check the condition of seals and
connector screw threads. Do not open warm or swollen product containers. Remove persons to safety
and alert fire brigade.
The temperatures which must be avoided are to be considered. Protect against heat. Protect from
direct sunlight. Protect contents from the effects of light.
Ensure adequate inhibitor and dissolved oxygen level.
Protection against fire and explosion:
Substance/product can form explosive mixture with air. Ground all transfer equipment properly to
prevent electrostatic discharge. Containers should be grounded against electrostatic charge. It is
recommended that all conductive parts of the machinery are grounded. Explosion-proof equipment is
not necessary when loading and processing of the product takes place at a minimum of 5 °C below the
flash point.
Heated containers should be cooled to prevent polymerization. If exposed to fire, keep containers cool
by spraying with water. Emergency cooling must be provided for the eventuality of a fire in the vicinity.
Sealed containers should be protected against heat as this results in pressure build-up. Avoid
influence of heat.
Conditions for safe storage, including any incompatibilities
Further information on storage conditions: Prior to storage ensure that the transfer equipment used
and the intended storage containers do not contain other substances/products. Before transfer to
stock the identity of the product must be proved to be without doubt. The entrance to storage rooms is
to be granted only to appropriately trained personnel.
The stabilizer is only effective in the presence of oxygen. Maintain contact with atmosphere containing
5 - 21% oxygen. Never use tanks with inert-gas installation for storage.
Risk of polymerization. Protect against heat. Protect from direct sunlight. Protect contents from the
effects of light. Avoid UV-light and other radiation with high energy. Protect against contamination.
All storage containers should at least be equipped with two high temperature alert devices.
Even if the product is stored and handled as prescribed/indicated it should be used up within the
indicated duration of storage.
Storage stability:
Storage temperature: < 35 °C
Storage duration: 12 Months
The stated storage temperature should be noted.
Avoid prolonged storage.
This product should be processed as soon as possible.
Ensure adequate inhibitor and dissolved oxygen level.
The product is stabilized, the shelf life should be noted.
Do not store with less than 10 % headspace above liquid.
Storage stability is based upon ambient temperatures and conditions described.
Shelf life is limited; see product information leaflet.
Storage temperature: 45 °C
A restabilization system should be used if the temperature in the storage container reaches the
indicated value.
Storage temperature: 60 °C
All personnel in a greater area should be evacuated if the temperature in the storage container
reaches the indicated value.
