4. First-aid measures
General advice:
Remove contaminated clothing.
If inhaled:
Keep patient calm, remove to fresh air, seek medical attention.
If on skin:
Flush with copious amounts of water for at least 15 minutes. Sterile protective dressing. Immediate medical
attention required.
If in eyes:
Immediately wash affected eyes for at least 15 minutes under running water with eyelids held open, consult
an eye specialist.
If swallowed:
Immediately rinse mouth and then drink plenty of water, do not induce vomiting, seek medical attention.
Never induce vomiting or give anything by mouth if the victim is unconscious or having convulsions.
Note to physician
Treatment: Treat according to symptoms (decontamination, vital functions), no known
specific antidote, administer corticosteroid dose aerosol to prevent pulmonary
odema.

91.40 掳F (DIN 51755)
Autoignition: 340 掳C (DIN 51794)
644.00 掳F (DIN 51794)
Lower explosion limit: 1.3 %(V) ( 29 掳C)
Upper explosion limit: 8.5 %(V) ( 67 掳C)
Suitable extinguishing media:
carbon dioxide, dry extinguishing media, water spray, foam
Hazards during fire-fighting:
Risk of violent self-polymerization if overheated in a container.
Protective equipment for fire-fighting :
Firefighters should be equipped with self-contained breathing apparatus and turn- out gear.
Further information :
Vapours are heavier than air and may accumulate in low areas and travel a considerable distance up to the
source of ignition. Fight fire from maximum distance.

6. Accidental release measures
Personal precautions:
Take appropriate protective measures.
Ensure adequate ventilation. Use personal protective clothing. Breathing protection required.
Environmental precautions:
Substance/product is RCRA hazardous due to its properties.
Cleanup :
Spills should be contained, solidified, and placed in suitable containers for disposal.
7. Handling and storage
Handling
General advice:
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.
Storage
General advice:
Risk of polymerization. Protect from direct sunlight.
8. Exposure controls and personal protection
Components with workplace control parameters
MEHQ
ACGIH TWA value 5 mg/m3 ;
Advice on system design:
Provide local exhaust ventilation to maintain recommended P.E.L.
Personal protective equipment
Respiratory protection:
Wear a NIOSH-certified (or equivalent) organic vapour/particulate respirator as needed. At concentrations <
250 ppm, use a chemical cartridge respirator. At concentrations > 250 ppm, use an air-supplied or self-
contained breathing apparatus.
Hand protection:
Chemical resistant protective gloves

10. Stability and reactivity
Conditions to avoid :
Avoid heat. Avoid oxygen content above the product of less than 5 %. Do not blanket with nitrogen. Avoid
U -light and other radiation with high energy. Avoid direct sunlight. Avoid prolonged storage. Avoid inhibitor
V
loss. Avoid excessive temperatures.
Substances to avoid:
polyvinylchloride, radical formers, free radical initiators, peroxides, mercaptans, nitro-compounds,
perborates, azides, ether, ketones, aldehydes, amines, nitrates, nitrites, oxidizing agent, reducing agents,
strong bases, acid anhydrides, acid chlorides, concentrated mineral acids, metal salts
Inert gas
Hazardous reactions :
Explosion and fire hazard exists under confined conditions. Ignitable air mixtures can form when the product
is heated above the flash point and/or when sprayed or atomized. Formation of explosive gas/air mixtures.
Risk of spontaneous and violent self-polymerization if inhibitor is lost or product is exposed to excessive
heat. Risk of spontaneous polymerization when heated or in the presence of UV radiation. With unstabilised
product, spontaneous polymerisation may occur e.g. through ambient heat. Polymerization coupled with heat
formation. Polymerization produces gases which may burst closed or confined containers. Reactions may
cause ignition.
Risk of spontaneous polymerization by oxygen depletion of the liquid phase.
