2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute Swallowed
Ingestion may result in gastric disturbances. Eye
The product is irritating to eyes. Skin
Contact with skin may result in irritation with discomfort or rash. Inhaled
Inhalation is likely to result in slight respiratory irritation. 2.2 Health Effects - Chronic
Prolonged contact with skin can result in drying of the skin. Loner exposures may cause dermatitis and deep burns. Prolonged eye contact may result in burns and permanent eye injury.
2.3 First Aid
Swallowed
Give water to drink. DO NOT induce vomiting. Call a physician. Never give anything by mouth to an unconscious person.
Eye
Wash affected eyes for at least 15 minutes under running water with eyelids held open. Consult an eye specialist.
Skin
Wash affected areas with copious quantities of water and soap. Remove contaminated clothing and wash before reuse.
Inhaled
Remove victim to fresh air. If not breathing give artificial respiration. If breathing is difficult give oxygen. Seek medical advice if effects persist.
First Aid Facilities
Ensure an eye bath and safety shower are available and ready for use.
2.5 Advice to Doctor
Activated charcoal slurry may be administered. To prepare activated charcoal slurry, suspend 50 grams activated charcoal in 400 mls water and mix thoroughly. Administer 5 ml/kg, or 350 ml for an average adult. Treat according to symptoms.
2.6 Toxicity Data
Oral LD50 = 5700 mg/kg (rat) Inhalation LC50 = > 7.7 mg/l/4h (fine dust that can enter the lungs; rat) Primary skin irritation/rabbit/BASF test : non-irritant Primary eye irritation/rabbit/BASF test: irritant Acute inhalation hazard (rat; test results depending on toxicity and volatility) : No mortalities after 8hr exposure in a highly enriched and/or saturated atmosphere at 20 deg C. Genotoxicity: Ames-test : No mutagenic effect.
3. PRECAUTIONS FOR USE
3.1 Exposure Standards
TLV (ACGIH) = 5 mg/m3, 8hr TWA
3.2 Engineering Controls
Ensure workplace is well ventilated.
3.3 Personal Protection
Respiratory protection - approved dust respirator or dust mask as necessary or if breathable dust is formed. Eye protection - wear chemical goggles. Skin protection - wear PVC, rubber, neoprene or nitrile gloves. Wear coveralls, apron, boots as necessary to minimise contact. The usual precautions for the handling of chemicals must be observed.
3.4 Flammability
Combustible. Keep away from heat, sparks or naked flames. Like most organic powders or crystals, under severe dusting conditions, this material may form explosive mixtures in air. SAFE HANDLING INFORMATION
4.1 Storage / Transport
Avoid dust generation. Keep away from heat, sparks and flames. Store in a well ventilated place. Keep container tightly closed. DO NOT store or consume food, drink or tobacco in areas where they may become contaminated with this material. Unloading of bulk (1000 kg) bags can generate voltage levels sufficient to contribute a spark hazard. Take precautionary measures against static discharges. Avoid dust formation. Avoid excessive heat and ignition sources. Containers should be stored tightly sealed in a dry place. Handle in accordance with good industrial hygiene and safety practice.
4.2 Packaging / Labelling UN No. N/A Class None Allocated Sub Risk None Allocated Hazchem Code N/A Pack Group 0 EPG No. N/A Shipping Name ADIPIC ACID Hazard IRRITANT
Risk Phrases R36 Irritating to eyes.
Safety Phrases S2 Keep out of the reach of children.
4.3 Spills and Disposal
Spills
Evacuate unprotected personnel from danger area. Contain - prevent contamination of drains and waterways. Shut off all possible sources of ignition, ie. heat, spark, flame, friction or electricity.
Clean up using a shovel. Sweep up or recover undamaged or minimally contaminated material for use or reclamation. Neutralise spills with soda ash.
Disposal
Must be disposed to approved landfill or by special means e.g suitable incineration, in accordance with local regulations. Uncleaned empties should be disposed of in the same manner as the contents.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Product may form explosive dust-air mixtures. Avoid contact with incompatibles Product may react exothermically with alkalis.
Extinguishing Media
Fire-fighters should wear full protective clothing including self-contained breathing apparatus. Cool fire-exposed tanks/containers with water spray. Keep personnel upwind of fire. Water may cause frothing. Uuse water spray type extinguisher. 5 OTHER INFORMATION
