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

Release of substance/product can cause fire or explosion.
Personal precautions, protective equipment and emergency procedures:
Ensure adequate ventilation. Use personal protective clothing. Breathing protection required. Take appropriate protective measures

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.
For residues: Pick up with suitable absorbent material.
Clean contaminated floors and objects thoroughly with water and detergents, observing environmental regulations. Dispose of absorbed material in accordance with 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. Provide basic employee training to prevent/minimize exposures. 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. 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 contents from the effects of light. Protect from direct sunlight.
Ensure adequate inhibitor and dissolved oxygen level.
Ensure that there is no crystallized product in the container before use. Obtain Information from supplier/ manufacturer before dissolving totally or partially crystallized product. The ambient temperature of the container may not exceed the stated temperature limit when melting the product or keeping it at moderate temperature.

Protection against fire and explosion:
Substance/product can form explosive mixture with air. Ground all transfer equipment properly to prevent electrostatic discharge. 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. Containers should be grounded against electrostatic charge. It is recommended that all conductive parts of the machinery are grounded.
Heated containers should be cooled to prevent polymerization. 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. If exposed to fire, keep containers cool by spraying with water. 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 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.
Do not store product below the indicated minimum temperature, because crystallization should be absolutely avoided.

Storage stability:
Storage temperature: 10 - 35 °C
Storage duration: 12 Months
The stated storage temperature should be noted.
Avoid prolonged storage.
Ensure adequate inhibitor and dissolved oxygen level.
The product is stabilized, the shelf life should be noted.
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.
Do not store with less than 10 % headspace above liquid.
Storage stability is based upon ambient temperatures and conditions described.

Exposure controls / personal protection

Personal protective equipment:

Respiratory protection:
Wear respiratory protection if ventilation is inadequate. 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:
Chemical resistant protective gloves (EN 374)
Suitable materials for short-term contact (recommended: At least protective index 2, corresponding > 30 minutes of permeation time according to EN 374) butyl rubber (butyl) - 0.7 mm coating thickness
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.
Manufacturer's directions for use should be observed because of great diversity of types.

Eye protection:
Tightly fitting safety goggles (splash 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:
Wearing of closed work clothing is required additionally to the stated personal protection equipment. Handle in accordance with good industrial hygiene and safety practice. Avoid contact with the skin, eyes and clothing.
