Section 3 - Hazards Identification


This product is not classified as hazardous according to Directive 67/548/EEC

           Potential Health Effects

Eye:                                 Concentrated solutions may cause mild irritation.

Skin:                                  May cause skin irritation. Heated product may cause burns on contact. In case of contact with                                                        molten rosin, do not attempt to remove from skin. Cool for at least 15 minutes under running                                                                    water and seek medical attention.

Ingestion:                              May cause irritation of the digestive tract if a large amount is ingested.

Inhalation:                              Not applicable at ambient temperature. May cause respiratory tract irritation if powder is inhaled.

Chemical Hazards

When exposed to air, powdered rosin may oxidize. Oxidized rosin is a skin sensitizer. When over-heated, fumes may be formed, which may cause asthmatic attacks.    



Section 4 - First Aid Measures

           Eyes:                                                             Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the                                                                                                 upper and lower eyelids. Get medical aid.

Skin:                                                                Get medical aid. Flush skin with plenty of water for at least 15 minutes while                                                                                                   removing contaminated clothing and shoes.

           Ingestion:                                                            Get medical aid. Do not induce vomiting. Rinse mouth out with water but do not                                                                                                       drink.

          Inhalation:                                                            Remove from exposure and move to fresh air immediately. If not breathing, give                                                                                          artificial respiration. If breathing is difficult, give oxygen. Get medical aid.

           Notes to Physician:                                 Treat symptomatically and supportively.


Section 5 - Fire Fighting Measures

General Information:                                          As in any fire, wear a self-contained breathing apparatus in pressure-demand,                                             MSHA/NIOSH (approved or equivalent), and full protective gear.

Extinguishing Media:                             Use dry chemical, carbon dioxide, or chemical foam. Water jet will scatter the                                       product.

Hazardous Decomposition/                               Can form flammable or explosive mixtures when finely divided dust is suspended in

Combustion Products:                                       the air.


Section 6 - Accidental Release Measures

           General Information:                                          Use proper personal protective equipment as indicated in Section 8.

Environmental                                            Should not be released into the environment. Prevent further leakage or

Precautions:                                                           spillage if safe to do so.

Methods for cleaning up:                        Sweep up material and dispose of as hazardous waste.


Section 7 - Handling and Storage

Handling:                                                                No special precautions required but avoid skin and eye contact. Prevent formation of mist. Eye and skin contact should be avoided if working at elevated temperatures.

Storage:                                                                  Store in a cool, dry place. Store in a well ventilated area. Keep fumes and dust to a minimum, in particular avoid formation of rosin dust.

Other Recommendations:                                Avoid contact with strong oxidizing agents.


Section 8 - Exposure Controls, Personal Protection

Engineering Controls:                                        Facilities storing or utilizing this material should be equipped with an eyewash                                                                                             facility and a safety shower. Use adequate ventilation to keep airborne                                                                                                            concentrations low.

Exposure Limits                                                   CAS# 8050-09-7: WEL (EH40UK2002) as nuisance dust

                                                                                    Total inhalable dust              10 mg/m3             Long term (8Hrs TWA)

                                                                                    Respirable dust                       4 mg/m3               Long term (8Hrs TWA)


Personal Protective Equipment

           Eyes:                                                             Wear tightly sealed chemical safety goggles.

           Skin:                                                              Wear appropriate protective gloves to prevent skin exposure.

           Clothing:                                            Wear appropriate protective clothing to prevent skin exposure.

           Respirators:                                               Follow the OSHA respirator regulations found in 29 CFR 1910.134 or European                                                                                          Standard EN 149. Use a NIOSH/MSHA or European Standard EN 149 approved                                                                                           respirator if exposure limits are exceeded or if irritation or other symptoms are                                                                                              experienced.

Section 11 - Toxicological Information



CAS# 8050-09-7


Oral 7600 mg/kg (rat)


Excessive inhalation of dust, or fumes when heating, may cause bronchial irritation. Noxious and irritating fumes may be given off upon over-heating. Over 400°C vapours may give rise to products which could cause asthmatic attacks.


Caution. When exposed to air, powdered rosin may oxidize. Oxidized rosin is a skin sensitizer. Short term contact may cause irritation. Prolonged or repeated contact may cause sensitization insusceptible individuals.


May be irritating to eyes by mechanical abrasion.


Unlikely to cause internal irritation if ingested.
