2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute Swallowed
Harmful by ingestion, may cause vomiting. Eye
Severly irritating to the eyes causing inflammation of the eye tissue, irritation and lacrimation. Skin
Causes severe burns. May be absorbed through the skin. Inhaled
Inhalation of product, gases, fumes, vapours or dust may cause shortness of breath, tightness of the chest, a sore throat and cough. Higher exposure may cause lung oedema, circulatory collapse and unconsciousness. Inhalation of high vapour concentrations can cause CNS-depression and narcosis. 2.2 Health Effects - Chronic
Danger of serious damage to health by prolonged exposure through inhalation, in contact with skin and if swallowed. Danger of very serious irreversible effects. May cause sensitisation of susceptible persons. Benzyl chloride has to be considered as a suspected human carcinogen according to the "International Agency for Research on Cancer (IARC)". Prolonged or repeated exposure may cause weakness, damp/clammy skin, itching, skin rash/inflammation, excited/ restless, sleeplessness, headache, change in the haemogramme/blood composition, respiratory difficulties, loss of appetite and tremors.
2.3 First Aid
Swallowed
Immediately give lots of water to drink. Never give water to an unconscious person. Do not allow vomiting. Consult a doctor or seek medical attention.
Eye
Rinse eyes immediately with plenty of water for at least 15 minutes. Do not apply neutralising agents. Consult a doctor.
Skin
Dangerous amounts can be absorbed through the skin. Take off all contaminated clothing immediately. Wash off immediately with soap and plenty of water. Wash immediately with lots of water and soap for 15 minutes. If irritation persist seek medical attention.
Inhaled
In case of accidental inhalation provide fresh air, rest and warmth. Oxygen or artificial respiration if needed. Symptoms of poisoning may not appear for several hours. Keep under medical supervision for at least 24 hours. Seek medical attention immediately. If unconscious maintain adequate airway and respiration.
First Aid Facilities
Ensure an eye bath and safety shower are available and ready for use.
2.5 Advice to Doctor
Treat symptomatically based on judgement of doctor and individual reactions of patient.
2.6 Toxicity Data
Oral LD50 = 440 mg/kg (rat) Inhalation LC50 = 1.8 MG/L/4HR (RAT) May cause sensitisation of susceptible persons. Animal experiments showed mutagenic and teratogenic effects. TDLO/intraperitoneal 5D male/mouse = 250 mg/kg Paternal effects : spermatogenisis. TDLO/Oral 6-15D preg./rat = 1 g/kg effects on embryo or foetus : fetotoxicity. TDLO/Oral/Mouse = 31 g/kg effects : vascular and gastrointestinal tumors; Carcinogenic by RTECS criteria.
3. PRECAUTIONS FOR USE
3.1 Exposure Standards
Worksafe recommends the following exposure standards : Benzyl chloride : TWA = 1ppm (5.2 mg/m3)
3.2 Engineering Controls
Measure the concentration of the air regularly. Work under local exhaust/ ventilation.
3.3 Personal Protection
Respiratory protection - In case of insufficent ventilation wear suitable respiratory equipment such as gas mask with filter type A respirator, gas mask with filter type B respirator or dust/aerosol mask with filter type P2. Eye protection - Wear face shield. Skin protection - Wear protective gloves and clothing. Materials for protective clothing are Tetrafluoroethylene and PVA. Handle in accordance with good industrial hygiene and safety practice. Wash hands and face thoroughly after handling and before work breaks, eating, drinking, smoking and using toilet facilities.
3.4 Flammability
Keep away from heat and ignition sources - NO SMOKING. Ventilate area to prevent build up of flammable vapours. SAFE HANDLING INFORMATION
4.1 Storage / Transport
Keep container tightly closed. Store in a cool, dry area. Keep away from heat sources, oxidising agents, metals and combustible materials. Observe very strict hygiene - avoid contact. Do not discharge waste into the drain. Avoid contact of substance with water. Remove contaminated clothing immediately.
4.2 Packaging / Labelling UN No. 1738 Class 6.1 Sub Risk 8 Hazchem Code 2W Pack Group II EPG No. 39 Shipping Name BENZYL CHLORIDE Hazard TOXIC
Risk Phrases R22 Harmful if swallowed. R23 Toxic by inhalation. R37/38 Irritating to respiratory system and skin. R40 Possible risk of irreversible effects. R41 Risk of serious damage to eyes.
Safety Phrases S1/2 Keep locked up and out of the reach of children. S36/37 Wear suitable protective clothing and gloves. S38 In case of insufficient ventilation, wear suitable respiratory equipment. S45 In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible).
4.3 Spills and Disposal
Spills
Evacuate personnel to safe areas. Keep people away from and upwind of spill. Remove all sources of ignition. Clean up personnel should wear full protective clothing including self-contained breathing apparatus. Prevent soil and water pollution. Substance must not be discharged into the sewer.
Damaged/cooled tanks must be emptied. Take up liquid spill into a non combustible material e.g sand, earth, vermiculite. Shovel absorbed substance into open drums or neutralise spill with soda (sodium carbonate) or slaked lime. Wash neutralise substance down with an excess of water.
Disposal
If recycling is not practicable, dispose of in accordance with all Local, State and Federal regulations at an approved waste disposal facility. Empty containers should be transported/delivered using a registered waste carrier for local recycling or waste disposal.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Material is sensitive to air. Product polymerises on exposure to temperature rise : pressure rise and possible bursting of conatiner. Decomposes slowly on exposure to water (moisture) releasing toxic and corrosive gases/vapours (hydrogen chloride). Violent to explosive reaction on exposure to water (moisture) with some metals. Hazardous decomposition products include hydrogen chloride, phosgene, chlorine, carbon monoxide, carbon dioxide. Reacts exothermically with some compounds. Reacts violently with strong oxidisers. Unstabilised product may polymerise with many compounds (e.g with some metals, releasing heat resulting in increased fire or explosion risk and also release of toxic and corrosive gases/vapours (hydrogen chloride). Avoid contact with heat and moisture.
Extinguishing Media
Use water spray, polyvalent foam, alcohol foam, polymer foam or BC powder. Do not use solid water jet ineffective as extinguishing medium. Cool tanks or drums with water spray/remove them into safety. Dilute toxic gases with water spray. Take account of toxic firefighting water. Fire fighters should wear full protective gear such as self-contained breathing apparatus and a gas tight suit. 5 OTHER INFORMATION
