HAZARDS IDENTIFICATION Human health hazards Safety hazards Environmental hazards : Harmful by inhalation. May cause moderate irritation to skin and eyes. May cause lung damage if swallowed. Prolonged exposure may cause organ system damage: Central nervous system, kidney, liver, auditory system. : Highly flammable. In use, may form flammable/explosive vapour-air mixture. Vapours are heavier than air. Vapours may travel across the ground and reach remote ignition sources causing a flashback fire danger. : Due to high evaporation rates no significant environmental hazards. Toxic to aquatic organisms. 4. FIRST AID MEASURES Symptoms and effects First Aid - Inhalation First Aid - Skin First Aid - Eye First Aid - Ingestion : Irritation of the skin, eyes and respiratory tract. Headache, nausea, dizziness, narcosis. : Remove to fresh air. If rapid recovery does not occur, obtain medical attention. : Remove contaminated clothing. Wash skin with water using soap if available. If persistent irritation occurs, obtain medical attention. : Flush eye with water. If persistent irritation occurs, obtain medical attention. : Do not induce vomiting. If rapid recovery does not occur, obtain medical attention. - 1/7 - <To be provided by the supplier> , . , .

FIRE FIGHTING MEASURES Specific hazards Extinguishing media Unsuitable extinguishing media Protective equipment : Hazardous combustion products may include carbon monoxide and formaldehyde. Will float and can be reignited on surface water. The vapour is heavier than air, spreads along the ground and distant ignition is possible. : Foam. Dry chemical powder, carbon dioxide, sand or earth may be used for small fires only. : Water in a jet. : Full protective clothing and self-contained breathing apparatus. 6. ACCIDENTAL RELEASE MEASURES Personal precautions Personal protection : Avoid contact with skin, eyes. Ventilate contaminated area thoroughly. Do not breathe vapour. Extinguish naked flames. Remove ignition sources. No smoking. Avoid sparks. Evacuate the area of all non-essential personnel. Shut off leaks, if possible without personal risk. : Wear fluorocarbon (Viton) rubber gloves, PVC*) one-piece suit with integral hood, safety boots - rubber, knee length. Wear full face-piece respirator with organic vapour canister and built-in particulate filter NPF 400 (gas only). In a confined space, wear self-contained breathing apparatus open circuit type NPF 2000. *) please note that PVC has a breakthrough time of about 30 min. Viton may be a more appropriate protective material. Environmental precautions : Prevent contamination of soil and water. Prevent from spreading or entering into drains, ditches or rivers by using sand, earth, or other appropriate barriers. Clean-up methods - small : Absorb or contain liquid with sand, earth or spill control spillage material. Shovel up and place in a labelled, sealable container for subsequent safe disposal. Put leaking containers in a labelled drum or overdrum. Scrub contaminated surfaces with detergent solution. Clean-up methods - large : Transfer to a labelled, sealable container for product spillage recovery or safe disposal. Treat residues as for small spillage. Other information : Risk of explosion. Inform the emergency services if liquid enters surface water drains. Vapour may form an explosive mixture with air. - 2/7 <To be provided by the supplier> , . , .

HANDLING AND STORAGE Handling Handling temperatures Storage Storage temperatures Product transfer Recommended materials Unsuitable materials : Avoid contact with skin, eyes and clothing. Do not breathe vapour. Only use in well ventilated areas. Use local exhaust extraction. Extinguish any naked flames. Remove ignition sources. Avoid sparks. Do not smoke. Do not empty into drains. : Ambient. : Keep away from direct sunlight and other sources of heat or ignition. Do not smoke in storage areas. : Ambient. : Earth all equipment. : For containers or container linings, use stainless steel, zinc silicate, epoxy resins : natural, butyl, neoprene or nitrile rubbers ,most plastics 8. EXPOSURE CONTROLS/PERSONAL PROTECTION Ethylbenzene TLV/ACGIH TWA (8 h) = 100 TWA (8 h) = 434 STEL (15 min) = STEL (15 min) = Engineering control measures ppm mg/m3 125 ppm 543 mg/m3 : Use local exhaust ventilation. Local guidelines on emission limits for volatile substances must be observed for the discharge of exhaust air containing vapour. Hygiene measures Respiratory protection : Launder contaminated clothing before re : If engineering controls do not maintain airborne concentrations to a level which is adequate to protect worker health, select respiratory protection equipment suitable for the specific conditions of use and meeting relevant legislation. Where air-filtering respirators are unsuitable (e.g., airborne concentrations are high, risk of oxygen deficiency, confined space) use appropriate positive pressure breathing apparatus. Where air-filtering respirators are suitable, select an appropriate combination of mask and filter. Select a filter suitable for combined particulate/organic gases and vapours [boiling point >65 °C(149 °F)] meeting EN141. No respiratory protection is ordinarily required under normal conditions of use. Hand protection : neoprene or nitrile rubber gloves (splash resistance), or fluorocarbon rubber (Viton) gloves (good resistance for about 6 hours) : chemical monogoggles : safety shoes or boots - chemical resistant standard issue work clothes Eye protection Body protection - 3/7 <To be provided by the supplier> , . , .

ECOLOGICAL INFORMATION Mobility Persistence/ degradability Bioaccumulation Acute toxicity - fish Acute toxicity invertebrates Acute toxicity - algae Acute toxicity - bacteria Sewage treatment Other information : Floats on water. Dissolved material evaporates rapidly within a day from water or soil surfaces. If product enters soil, it will be mobile and may contaminate groundwater. : Readily biodegradable. Expected to persist under anaerobic conditions. Oxidises rapidly by photo-chemical reactions in air. : Does not bioaccumulate significantly. The calculated Bio-concentration factor is 91. Studies indicate that the bioaccumulation might be low r than the log Pow suggests. : Toxic, 1 < LC/EC/IC 50 <= 10 mg/l . : Toxic, 1 < LC/EC/IC 50 <= 10 mg/l . : : : : Toxic, 1 < LC/EC/IC Toxic, 1 < LC/EC/IC Toxic, 1 < LC/EC/IC In view of the high product is unlikely aquatic life. 50 <= 10 mg/l . 50 <= 10 mg/l . 50 <= 10 mg/l . rate of loss from solution, the to pose a significant hazard to 13.
