* The CAS number is variable and depends on the exact identity of the modified rosins used. In the absence of data indicating that modified rosins are not sensitisers, Multicore Solders has classified them as Harmful, with Risk Phrase R 42/43. Risk phrases R 22 R 38 R 41 R 42/43 3. Harmful if swallowed Irritating to skin Risk of serious damage to eyes May cause sensitisation by inhalation and skin contact
HAZARDS IDENTIFICATION This product contains modified rosins. Prolonged or repeated skin contact may cause an allergic reaction to develop. Inhalation of the fumes produced during soldering will irritate the respiratory system. Prolonged or repeated exposure to flux fumes may cause the development of occupational asthma and may cause rashes on exposed skin. Animal studies with the glycol diether group of chemicals has identified reversible testicular atrophy, sperm damage and birth defects as a result of long term exposure. However, there have been no reported ill-effects in animals or humans from exposure to the specific glycol diether present in this product.

FIRST-AID MEASURES Inhalation The flux fumes given off when heated will irritate the nose and throat and can cause an asthmatic type reaction.
Remove affected person to fresh air. Obtain medical attention if there is any respiratory distress. Issue No: 2 Date: 26 March 1997 Number: HS LF069 Prepared by: Authorised by: Page 1 of 4
Ingestion
Will irritate the gastric tract.
If the casualty is unconscious but breathing, place on one side in the recovery position. If breathing has stopped apply artificial respiration or apply oxygen by mask. If the patient is conscious then encourage him/her to rinse the mouth out several times with water. Do not induce vomiting nor give anything to drink if the patient finds it difficult to swallow. Obtain urgent medical attention. Skin Contact Skin irritation and rash may result on prolonged or repeated contact with the flux or flux fume.
Wash the affected parts of the body with soap and warm water. If skin irritation develops seek medical advice. Eye Contact The flux fumes emitted when heated will irritate the eyes.
Flush immediately with plenty of water. Ensure that the eyeball and the inside of the eyelids are properly bathed by gently prising open the eyelids. Also make sure that the contaminated water runs off the face away from the eyes. Obtain urgent medical attention. 5. FIRE FIGHTING MEASURES Extinguishers Suitable - dry chemical, carbon dioxide, water spray or foam. Unsuitable - water jet.
Under fire conditions this flux will release smoke, carbon monoxide and carbon dioxide. Fire fighters should wear full protective clothing and self-contained, positive pressure breathing apparatus. 6. ACCIDENTAL RELEASE MEASURES Avoid contact with the skin and eyes. subsequent disposal. 7. HANDLING AND STORAGE The fumes produced during soldering should be extracted away from the breathing zone of the operators. Ensure that the area is well ventilated. Avoid inhaling the flux fume. Wash hands with soap and warm water after handling, particularly before eating, drinking or smoking. This product should be stored in a cool, dry area. 8. EXPOSURE CONTROLS / PERSONAL PROTECTION Engineering methods to prevent or control exposure are preferred. Local exhaust or dilution ventilation and control of process conditions are suitable methods. Where engineering controls and work practices are not effective in controlling exposure then suitable respiratory protective equipment should be used. Occupational Exposure Limits None assigned for the ingredients of tthis product. From 1/1/97 the Occupational Exposure Standard for rosin-based solder flux fume is withdrawn since it measures formaldehyde levels which have been found to be a poor indicator of health risk. The proposed new method measures the resin-acid particulates in the fume and will be accompanied by a Maximum Exposure Limit likely to be introduced in 1999. In the meantime exposure to rosin-based flux fume should be prevented or, where this is not reasonably practicable, adequately controlled. Prevention of exposure should take precedence over adequate control. Users should consult the more detailed information and guidance published by the HSE. Respiratory Protection: Necessary if there is a risk of exposure to high concentrations of flux fumes. Eye Protection: Skin Protection: Operators should wear safety glasses or goggles. Butyl rubber gloves and suitable workwear to protect the operators own clothing. Scrape up the spillage and transfer to a suitable closed container for
Under the Control of Substances Hazardous to Health Regulations 1994, there is a requirement for personnel who are exposed to substances hazardous to health to be under appropriate health surveillance. Guidance on this can be found in the HSE publication Preventing Asthma at Work - How to Control Respiratory Sensitisers. Issue No: 2 Number: HS LF069 9. PHYSICAL AND CHEMICAL PROPERTIES Page 2 of 4

10. STABILITY AND REACTIVITY Materials to Avoid The flux will react vigorously with strong oxidising agents, possible with explosive violence. 11. TOXICOLOGICAL INFORMATION Acute Toxicity The flux fumes produced during soldering will irritate the nose and throat. For personnel that have developed an allergic reaction to modified rosin fumes, further exposure may cause symptoms of asthma (attacks of wheezing, chest tightness and breathlessness), alveolitis (breathlessness and flu-like symptoms), or rhinitis and conjunctivitis (runny or stuffy nose and watery or prickly eyes typical of hay fever.) Exposure to flux fumes may cause skin irritation and rash. Modified rosin can also cause sensitisation by skin contact causing redness, irritation, rash or pustules. LD50 (oral, rat) : Modified rosin Glycol diether Malonic acid Terpineol >2500 mg/kg 3900 mg/kg 1310 mg/kg 4300 mg/kg
Chronic Toxicity Prolonged or repeated skin contact with modified rosin can lead to an allergic contact dermatitis. The skin will react by producing anything from weals to pustules. Prolonged or repeated inhalation of modified rosin fumes may lead to occupational asthma. Cases of occupational asthma due to inhalation of rosin fumes produced from soldering fluxes are reportable under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995. 12. ECOLOGICAL INFORMATION No information is available on the main ingredients of this product. 13. DISPOSAL CONSIDERATIONS This product should be disposed of in accordance with local and national legislation. In the UK this is the Control of Pollution Act 1974, the Environmental Protection Act 1990 and regulations made under them. This product contains a high proportion of organic solvents. It is a prescribed substance for release into land. The recommended disposal method is controlled incineration. If correctly incinerated the product will decompose to carbon dioxide and water only. 14. TRANSPORT INFORMATION This product is not classified as hazardous for transport. 15. REGULATORY INFORMATION Classification according to the Chemicals (Hazard Information and Packaging for Supply) Regulations 1994 : R42/43 R38 S23 S24/25 S37 May cause sensitisation by inhalation (flux fumes) and by skin contact Irritating to skin Do not breathe fumes Avoid contact with skin Wear suitable gloves
