Section 3 - Hazards Identification

EMERGENCY OVERVIEW

Appearance: yellow-green solid. Harmful if swallowed. May cause respiratory and digestive tract irritation. May cause central nervous system depression. May be absorbed through intact skin. Danger! Causes severe eye burns. Causes skin irritation. Causes respiratory tract irritation.
Target Organs: Central nervous system.


Potential Health Effects
Eye: Causes severe eye burns. Contact may cause discoloration, redness, swelling, and formation of eye lesions. May cause corneal edema, ulceration, and scarring. Prolonged exposure to vapor can lead to gradual deposition of pigment in the cornea and conjunctiva which may result in severe visual disturbances. Causes small opacities of the cornea and structural corneal changes that result in loss of visual activity. Contact may cause discoloration, redness, swelling and formation of eye lesions.
Skin: Causes skin irritation. Depigmentation and skin lesions may occur. May cause discoloration, erythema (redness), swelling, and the formation of papules and vesicles (blisters). Prolonged contact may lead to necrosis.
Ingestion: Harmful if swallowed. May cause irritation of the digestive tract. Ingestion may cause convulsion, respiratory difficulties and decrease d blood pressure.
Inhalation: Causes respiratory tract irritation. May cause adverse central nervous system effects including headache, convulsions, and possible death. May produce asphyxia due to pulmonary damage and effects on the hemoglobin. May produce clonic convulsions, respiratory difficulties, decreased blood pressure and death due to medullary centers.
Chronic: Prolonged or repeated exposure may cause permanent eye damage.

Section 4 - First Aid Measures


Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Do NOT allow victim to rub eyes or keep eyes closed.
Skin: Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.
Ingestion: If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.
Inhalation: Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician: Treat symptomatically and supportively.
Antidote: None reported.

Section 5 - Fire Fighting Measures


General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Dusts at sufficient concentrations can form explosive mixtures with air.
Extinguishing Media: In case of fire, use water, dry chemical, chemical foam, or alcohol-resistant foam.

Section 6 - Accidental Release Measures


General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks: Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. Remove all sources of ignition. Provide ventilation.

Section 7 - Handling and Storage


Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well-ventilated area. Minimize dust generation and accumulation. May form flammable dust-air mixtures. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Do not ingest or inhale.
Storage: Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.

Section 8 - Exposure Controls, Personal Protection


Engineering Controls: Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.

Ecotoxicity: Fish: Rainbow trout: LC50 = 0.125 mg/L; 96 Hr.; UnspecifiedFish: Fathead Minnow: LC50 = 0.045 mg/L; 96 Hr.; UnspecifiedBacteria: Phytobacterium phosphoreum: EC50 =2.09 mg/L; 5-30 minutes; Microtox test No data available.
Environmental: If released to soil it is likely to leach (estimated Koc of 30) and may volatilize and photodegrade on soil surfaces. If released to the aquatic environment, it may be degraded by photolysis as it absorbs UV radiation. In water, 1,4-benzoquinone is not expected to volatilize, adsorb to particulate matter or sediment, or biioaccumulate in aquatic organisms. Biodegradation in water may be important based upon the rapid degradation susceptible to direct photolysis.
Physical: According to a suggested classification scheme, a vapor pressure of 37.5 mm Hg at 25 deg C indicates that 1,4-benzoquinone will exist in the vapor phase in the ambient atmosphere. Vapor phase 1,4-benzoquinone is degraded in the atmosphere by reaction with photochemically produced hydroxyl radicals and ozone; the combined half-life for this reaction in air is estimated to be about 33.6 minutes. Since it absorbs UV radiation in environmentally significant wavelengths(4,5), photolysis is also possible.
Other: No information available.

Section 13 - Disposal Considerations
