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.
Avoid contact with the skin, eyes and clothing. 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. Do not discharge into the subsoil/soil.
Methods and material for containment and cleaning up
For small amounts: Pick up with suitable absorbent material. Dispose of absorbed material in accordance with regulations.
For large amounts: Pump off product. Dispose of absorbed material in accordance with regulations.
Clean contaminated floors and objects thoroughly with water and detergents, observing environmental
regulations. Subject contaminated water to waste water treatment.
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. Avoid all sources of ignition: heat, sparks,
open flame. Vapours may form explosive mixture with air. Ignitable mixtures can be formed in the emptied container.
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. Avoid UV-light and other radiation with high energy.
Protect against contamination. Protect contents from the effects of light. Maintain contact with atmosphere containing 5 - 21% oxygen.
All storage containers should be equipped with 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: 2 - 35 °C
Storage duration: 12 Months
The stated storage temperature should be noted.
Avoid prolonged storage.
Ensure adequate inhibitor and dissolved oxygen level.
It is recommended to keep a safe distance of +2 degrees above the crystallization range.
Do not store with less than 10 % headspace above liquid.
The product is stabilized, the shelf life should be noted.
Storage stability is based upon ambient temperatures and conditions described.

Exposure controls / personal protection
Exposure controls
Personal protective equipment
Respiratory protection:
Suitable respiratory protection for lower concentrations or short-term effect: Gas filter for gases/vapours of organic compounds (boiling point >65 °C, e. g. EN 14387 Type A)
Hand protection:
Suitable materials also with prolonged, direct contact (Recommended: Protective index 6, corresponding > 480 minutes of permeation time according to EN 374):
nitrile rubber (NBR) - 0.4 mm coating thickness
Manufacturer's directions for use should be observed because of great diversity of types.
Supplementary note: The specifications are based on tests, literature data and information of glove manufacturers or are derived from similar substances by
analogy. Due to many conditions (e.g. temperature) it must be considered, that the practical usage of a chemical-protective glove in practice may be much
shorter than the permeation time determined through testing.
Eye protection:
Safety glasses with side-shields (frame goggles) (e.g. EN 166)
Body protection:
Body protection must be chosen depending on activity and possible exposure, e.g. apron, protecting boots, chemical-protection suit (according to EN 14605
in case of splashes or EN ISO 13982 in case of dust).
General safety and hygiene measures
Avoid contact with skin. Avoid inhalation of vapour. Wearing of closed work clothing is required additionally to the stated personal protection equipment.
Handle in accordance with good industrial hygiene and safety practice.
