Protection for first aid person：Rescuers should wear proper protective equipment like rubber
gloves, goggles.

5.

Fire fighting measures
Extinguishing media：Dry chemical powder, carbon dioxide, dry sand, foam

Prohibited extinguishing media：Water spray
Particular fire fighting：Move containers from fire area if it can be done without risk,
if not possible, apply water from a safe distance to cool andprotect surrounding area.
Dry chemical powder, carbon dioxide or dry sand should be
used for small fires. Foam extinguisher is effective for a large
scale fire.
Protection for firefighters：Wear breathing apparatus.

6.

Accidental release measures
Cautions for personnel：Wear proper protective equipment and avoid contact with skinand inhalation of vapor. Conduct operations from upwind andevacuate people downwind. Remove all sources of ignition. Keepaway personnel except for authorized ones from spillage areaby stretching ropes.
Cautions for environment：Attention should be given to avoid discharge of spilled productinto rivers and resulting environmental damage. When diluting
spill with large amounts of water, discharge of untreatedwastewater into the environment must be avoided.
Removal measure：Absorb spill with inert material (e.g., diatomaceous earth, sand)and flush spillage area with copious amounts of water.

Prevention of second accident：Remove nearby sources of ignition and prepare extinguishingmedia.

11. Toxicological information
Acute toxicity：Oral : Out of category
Dermal : Not possible to classify because of insufficient data.
Inhalation(vapor) : Not possible to classify because ofinsufficient data.
Inhalation (dust, mist) : Out of category
rat oral LD50=5000mg/kg
rat inhalation LC50=24mg/L/4H(mist)

Skin corrosion/irritation：Causes skin irritation(category 2)
In rabbit skin irritation test (OECD TG404 compliant), rabbits
showed slight redness from 1 hour after application andmoderate to severe redness after 144 hours. Based on thedata, it was classified into category 2.
Serious eye damage/eye irritation：Causes eye irritation(category 2B)
Following exposure of rabbit eyes to the substance 500mg for
24 hours, mild irritation was observed. Thus, it was classified－ 6/9 －No. DEFC0517

AQUALYTE Water Standard 0.1

into category 2B.
Respiratory sensitization or Skin sensitization：Respiratory sensitization : Not possible to classify because ofinsufficient data.
Regarding human health effects, nervousness, tension, anxiety
and bronchial asthma were observed in 27 factory workers
who were occupationally exposed to a product containing 30%
mesitylene (this substance) and 50% 1,2,4-trimethylbenzene forseveral years (hydrocarbon concentration of the vapor: 10-60ppm). However, the effects cannot be attributed to mesitylene
because the other isomer is mixed. Thus, the classification is
not possible because of insufficient data.
Skin sensitization : Not possible to classify because ofinsufficient data.
Mutagenicity：Not possible to classify because of insufficient data.
As for in vivo, there are negative data on micronucleus test inmouse bone marrow cells, and positive data only at high doses
on sister chromatid exchange test in mouse bone marrow cells.
As for in vitro, there are negative data on reverse mutation
test in bacteria.

Carcinogenic effects ：Not possible to classify because of insufficient data
Effects on the reproductive system：Not possible to classify because of insufficient data.
Specific target organ systemic toxicity single exposure：May cause respiratory irritation(category 3)・May cause
drowsiness and dizziness(category 3)
Human studies have shown that inhalation exposure causes
headache, dizziness, lethargy, incoordination, and vomiting, andingestion causes aspiration into the lungs resulting in chemical
pneumonia. Animal studies have shown that inhalation exposurein mice causes loss of righting reflex and central nervous
system depression, and inhalation exposure in rats revealed
EC50 for Rota-rod test is 963 ppm (4.73 mg/L), EC50 for
analgesia in the hot-plate test is 1,212 ppm (5.96 mg/L). The
effects on central nervous system in humans and experimental
animals are symptoms which generally fall under anestheticaction. Thus, it was classified into category 3 (respiratory tract
irritation, anesthetic action).
Specific target organ systemic toxicity repeated exposure－ 7/9 －No. DEFC0517

AQUALYTE Water Standard 0.1：Cause damage to organs (central nervous system, respiratoryorgans) through prolonged or repeated exposure(category 1)
In humans, effects on central nervous system (nervousness,tension, anxiety) and respiratory organs (asthmatic bronchitis)
were observed in many of 27 workers who were exposed tothe solvent containing 30% mesitylene (this substance) and 50%
1,2,4-trimethylbenzene for several years (hydrocarbonconcentration: 10-60 ppm). As with the case oftrimethylbenzene (mixture of isomers), it was classified into
category 1 (central nervous system, respiratory organs).
Aspiration hazard：May be fatal if swallowed and enters airways(category 1)
Since the substance is a hydrocarbon with a kinematic viscosityof 8.9 mm2/s (density: 0.8652 g/cm 3 (20 C)), it wasclassified into category 1.
