REACTIVE WITH: Strong oxidizing agents, particularly nitric acid, hydrogen peroxide & perchlorates
DECOMPOSITION PRODUCTS: may form explosive peroxides on prolonged contact with air.
8. PERSONAL HANDS: butyl rubber gloves. Other types may also be suitable, consult your supplier
PROTECTION EYES: safety glasses with side shields or chemical goggles
MEASURES: RESPIRATOR: not required if ventilation is adequate
CLOTHING: impervious (hands ,above) apron, boots, long sleeves if splashing is anticipated.
9. FIRST AID SKIN: Wash with soap and plenty of water. Remove contaminated clothing and do not reuse until thor-
PROCEDURES: oughly cleaned or
laundered.
EYES: Wash eyes with plenty of water, holding eyelids open. Seek medical attention promptly if there is
irritation.
INHALATION: Remove from contaminated area promptly. CAUTION: Rescuer must not endanger
himself! If breathing stops, administer artificial respirator and seek medical aid promptly.
INGESTION: Give plenty of water to dilute product. Do not induce vomiting. Keep victim quiet. If

NOTE: Inadvertent inhalation of vomiting material may seriously damage lungs. The risk and danger
of this is greater than the risk of poisoning through absorption of this relatively low-toxic product. The
stomach should only be emptied under medical supervision, after the inhalation of an airway to protect the
lungs.
10. EXPOSURE TWAEV ppm: 25 (skin)
LIMITS: LD50 ORAL: 1300
SKIN (mg/kg): 950
LC50 ppm INHALATIO: 2650
11. TOXICOLOGICAL EFFECTS ACUTE EXPOSSURE
INFORMATION: SKIN CONTACT: mild irritant ?severe if contact is prolonged
SKIN ABSORPTION: yes; toxic effect may occur by this route
EYE CONTACT: severely irritating, may not damage eyes
INHALATION: irritating?but low vapour pressure lessens inhalation hazard
INGESTION: headache, narcosis (depressant) & intoxication
EFFECTS OF CHRONIC EXPOSURE
GENERAL: repeated absorption may damage liver and kidneys; bone marrow damage has also been
reported
SENSITISING: not a sensitiser
CARCINOGENIC: experimental tumorigen at 3000ppm (very high exposure); no evidence of effects on
humans
REPRODUCTIVE EFFECT: no known effect in humans reproductive abnormalities observed in rodents,
but no useful conclusions can be drawn due to severe toxicity in the animals
SYNERGISTIC WITH: not known
ESTIMATED LD50: 1300mg/kg (oral, rat) 1400mg/kg (oral, mouse), 1500mg/kg (oral, rabbit); 950mg/kg
(skin, rabbit)
ESTIMATED LC50: 2650ppm (inhalation, rat)
12. ECOLOGICAL This product cannot accumulate in living tissue; this product is biodegradeable in the presence of oxygen.
INFORMATION:
13. DISPOSAL DO NOT FLUSH TO SEWER; may be incinerated in approved facility. This product cannot accumulate
CONSIDERAIONS: in living tisue - rapidly metabolized. This product is only slowly biodegradable; very low water solubility
ensures that spills migrate very slowly; halflife 4 days in presence of other carbon sources. Halflife in air
45 hours due to reaction with hydroxyl radicals.
14. CARCINOGENIC Experimental tumorigen at 3000ppm (very high exposure); no evidence of effects on humans.

16. HANDLING & Store and use in a cool dry environment, away from sources of ignition, heat, halogens and oxidizing
STORAGE: agents. Use with adequate ventilation. Low electrical conductivity makes this substance a static accu-
mulator. Ground the container before transferring or handling. Do not cut, drill, weld or grind near this
container. This product is absorbed through the skin, and may invalidate the TWAEV. Avoid contact with
skin and wash work clothes frequently. An eye bath safety shower must be available near the workplace.
17. ACCIDENTAL LEAK PRECAUTION: dyke to spillage and prevent environmental contamination
RELEASE HANDLING SPILL: ventilate contaminated area; recover free liquid with suitable pumps; absorb residue
MEASURES: on an inert sorbent, sweep & pick up using shovels & store in closed containers for disposal
WASTE DISPOSAL: DO NOT FLUSH TO SEWER; may be incinerated in approved facility
ENVIROINFO: this product cannot accumulate in living tissue; this product is biodegradeable in the pres-
ence of oxygen.
