2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute Swallowed
Corrosive. Swallowing can cause severe burns of the mouth, throat, and stomach. Can cause sore throat, vomiting, diarrheoa. May cause central nervous system depression. Symptoms may include lethargy, drowsiness, staggering, and sleepiness. Eye
Liquid causes severe burns to eyes. Vapour causes irritation of the eyes, with lachrymation, conjunctivitis, and corneal oedema. Skin
Corrosive. Symptoms of redness, pain, and severe burns can occur. May cause skin sensitisation. May be absorbed through the skin with possible systemic effects. Inhaled
Inhalation can cause severe irritation of mucous membranes and upper respiratory tract. Symptoms may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting. May cause pulmonary edema. 2.2 Health Effects - Chronic
Not expected to be sensitising.
2.3 First Aid
Swallowed
If swallowed, drink at least 1/2 l of lukewarm water or milk, induce vomiting. Seek medical attention immediately.
Eye
If eye contact occurs, immediately rinse under running water for at least 15 minutes with eyelids held open. Seek medical attention immediately.
Skin
If skin contact occurs, immediately wash off under running water. Apply sterile dressing and seek medical attention. Immediately remove contaminated clothing and wash thoroughly before reuse.
Inhaled
If vapours are inhaled, remove affected person to fresh air, while removing clothing. Provide the breathing support. Seek medical attention.
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 = 156 mg/kg (Rat) Dermal LD50 = 277 mg/kg (Rabbit) Dermal irritation (rabbit) = 7, very hazardous (cor-OECD-level 4), 2mg/24h SEV Eye irritation (rabbit) = 10, vitally hazardous (cor-OECD-level 4), 50U/24h SEV Acute inhalation hazard - no mortalities after 10 minutes exposure to an atmosphere of saturated vapours at 20 deg C; deaths occurred with further exposure (Rat) Sensitising - no sensitising effect Mutagencity - probably mutagen Inhalation LCL0 = 8000 ppm/4hr Inhalation LCLO = 7500 mg/kg
3. PRECAUTIONS FOR USE
3.1 Exposure Standards
Worksafe recommends : TWA 10 ppm (41 mg/m3)
3.2 Engineering Controls
Proper ventilation should be provided. Control measurements of the cyclohexylamine concentration in the working environment.
3.3 Personal Protection
Respiratory protection - protective mask with a filter against organic foams of the A-type. Eye protection - wear protective goggles or shield. Skin protection - wear protective gloves and clothing. Avoid eating, drinking and smoking at work. After work completion, wash your hands with hot water and soap, treat skin with suitable reparation means.
3.4 Flammability
Flammable. Keep away from all sources of ignition and heat. Earth all containers to reduce the possibility of sparks from static electricity. Dangerous fire hazard when exposed to heat, flame or oxidising agents. Vapours can form flammable mixtures with air. SAFE HANDLING INFORMATION
4.1 Storage / Transport
Product should be stored in ventilable rooms in original packaging or steel containers, the upper permissible storage temperature limit is 35 deg C. Avoid contact with foods, strong oxidising agents and concentrated strong acids.
4.2 Packaging / Labelling UN No. 2357 Class 8 Sub Risk 3 Hazchem Code 2W Pack Group II EPG No. 19 Shipping Name CYCLOHEXYLAMINE Hazard CORROSIVE
Risk Phrases R10 Flammable. R21/22 Harmful in contact with skin and if swallowed. R34 Causes burns.
Safety Phrases S1/2 Keep locked up and out of the reach of children. S36/37/39 Wear suitable protective clothing, gloves and eye/face protection. 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
DO NOT let product enter drains or water courses. Sources of ignition should be kept clear. Clean up personnel should wear full protective clothing with protective goggles, gloves and approved vapour respirator. Ensure proper ventilation.
Contain and soak up all spills with non-combustible absorbent material (eg. sand or earth). Use water spray to cool and disperse vapours. Place waste in labelled drums and hold for disposal. Flush away spill area with copious amounts of water.
Disposal
Dispose of in accordance with all Local, State and Federal regulations at an approved waste disposal facility by incineration. Empty drums and containers can be recycled or reprocessed if all product residues have been flushed out.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Flammable liquid. Vapours are heavier than air and may travel to a source of ignition and flash back. When heated to decomposition it may emit fumes of carbon oxides, hydrocarbons, nitrogen oxides, amine vapours and ammonia. Exothermic reaction with acids. Incompatible with acids, oxidising agents or halogens.
Extinguishing Media
In case of fire use smashed water, powder, foam or carbon dioxide. Fire fighter should wear full protective gear including a self-contained breathing apparatus. 5 OTHER INFORMATION
Other Information
The product is an alkali and before discharging into effluent treatment plants, neutralisation is generally required. The degradation activity of the activated sludge in effluent treatment plants should not be affected if this product is discharged correctly in low concentrations. The product does not contain any organically bound halogens. Degradation : test method - biological kinetic test. Evaluation - BSK5/CHSKCr = 0.64, very well degradable. Mobility = it can penetrate into living environment from waste waters. Cummulation = in appears in waters in case of escape. Acute toxicity for fish = 3.7 Leuciscus idus melatonus (48h) - LC0 = 50 mg/l, LC50 = 58 mg/l, LC100 = 82 mg/l Brachydanio rerio (96h) - LC0 = 200 mg/l, LC50 = 470 mg/l, LC100 = 600 mg/l Daphnia magna - LC0 = 50 mg/l, LC50 = 80 mg/l, LC100 = 102 mg/l Entosiphon sulcatum - LC100 = 0.69 mg/l Acute toxicity for bacteria = 3.4. Microcystis aeruginosa - LC0 = 0.02 mg/l Acute toxicity for animals = 5. Mouse - LC50 (inh.) = 1070 mg/kg
