4 FIRST AID MEASURES
4.1 inhalation:
Remove to fresh air, rest, sit half way up. Get medical help if discomfort persist.
skin:
Remove contaminated clothing. Wash thoroughly with soap and water.
eyes:
Flush thoroughly with water for 15 minutes and contact a doctor.
ingestion:
Wash out the mouth and transport immediately to a hospital.
5 MEASURES IN CASE OF FIRE
5.1 flash point: 10癈
5.2 explosion limits: air vol.% lower: 2.1 %
upper: 12.5 %
5.3 auto ignition temperature: 430癈
5.4 extinguisher method:
useful: Powder, A.F.F.F., foam and carbon dioxide.
not useful: Direct jet of water.
5.5 hazardous decomposition products: none
5.6 hazardous reactions:
When heated above the flash point, flammable vapours are emitted which can mix with air and
can burn or be explosive. Vapours are heavier than air and may travel to the source of ignition
and flash back. Heat can cause polymerisation with rapid release of energy which may rupture
container explosively.
6 ACCIDENTAL RELEASE MEASURES
6.1 leakage / spillage:
Warn bystanders. Eliminate sources of ignition. Prevent monomer from entering drains or
water sources. Collect liquid in a open barrel. Absorb spilled liquid with inert material as dry
earth or other absorbent material and transfer to a save place for disposal.
See point 13 for disposal of the liquid.
6.2 personal precautions:
See point 8 for personal protection.
6.3 environmental precautions:
See point 12 for information concerning the environment.

7 HANDLING AND STORAGE
7.1 handling:
Work in a well ventilated place. Material is inflammable, it must be kept away from naked
flames or other sources of ignition. Keep away from food, drinks, and animal feed.
7.2 storage:
Store in a cool dark place, separated from oxidising agents. Container may be filled only for 80
%. Keep container tightly closed to avoid evaporation of the product.
7.3 protection against fire and explosion:
Keep out of direct sunlight or any source of heat, sparks or flame. Take measures against the
build-up of electrostatic charges. In case of fire, keep any closed container of monomer cool by
using a fine water spray if they cannot be moved away.
8 PERSONAL PROTECTION
8.1 respiratory protection:
Local exhaust ventilation or an adequate mask with a filter useful for organic vapour (type
A2B2). Possible a half-mask with active carbon may be used (FHMPE).
hand protection: Polyvinylalcohol gloves. Warning: PVA is soluble in water!
eye protection: Protecting glasses.
other protection: None.
8.2 industrial hygiene:
Keep working clothes separately. Take off contaminated clothing immediately. Keep away
from food, drinks and animal feed.

10 STABILITY AND REACTIVITY
10.1 stability:
The liquid is stabilised with hydrochinon (CAS-regnr. 123-31-9). However polymerisation
may occur when the expiry date and/or storage temperature is considerable exceeded.
10.2 hazardous reactions:
When heated above the flash point, flammable vapours are emitted which can mix with air and
can burn or be explosive. Vapours are heavier than air and may travel to the source of ignition
and flash back. Heat can cause polymerisation with rapid release of energy which may rupture
container explosively.
10.3 hazardous decomposition products:
By use according the instructions; none.
11 INFORMATION ON TOXICITY
According to literature.
Methyl methacrylate is essentially non toxic when absorbed into the body by any route, but for some
few individuals is a powerful skin sensitiser. Apart from this skin allergy, human cases of ill health
caused by material are of a low probability.
Long-term inhalation test on rats and hamsters with exposure concentrations ranging from 100 to 400
ppm did not show any chronic toxic effects. However concentrations on excess of 100 ppm volume
may be irritating for some people. Handling of the product requires adequate ventilation to prevent
accumulation of vapours in work areas.
11.1 Methyl methacrylate:
Acute oral rat: LD50 = 7872 mg/kg
Acute skin rabbit: LD50 = 9400 mg/kg
Acute inhalation rat: LC50 = 7093 ppm/4 hours
Human patch test:
Approximate one-third of subjects developed mild redness at site of application. Twenty
percent showed sensitivity when tested 10 days later.
11.2 Crosslinker:
Acute oral rat: LD50 = 3300 mg/kg
Skin irritation rabbit: Not irritating
Eye irritation rabbit: Not irritating
4
11.3 Accelerator 2:
Skin irritation rabbit: Severe irritant
Eye irritation rabbit: Severe irritant
11.4 UV absorber:
Acute oral rat: LD50 = > 5000 mg/kg
Skin irritation rabbit: Not irritating
Eye irritation rabbit: Not irritating
12 ECOLOGICAL INFORMATION
The product should not be allowed to drain into sewers. There is a severe danger of explosion.
13 DISPOSAL CONSIDERATIONS
The product can be disposed as methyl methacrylate. The preferred method for disposal of waste
quantity's of methyl methacrylate is by incineration in accordance with local regulations.
