Rosin composition

1.2-3.5%. It is determined on customer’s requirements (The higher the rosin composition is, the better is the wetting and the faster the welding is. However, there would be more residue and smoke. The lower the rosin composition is, the slower is the wetting and welding is. Luckily, there would be less residue and smoke.)

Major Hazard Effect

Hazard warning for health:

Inhalation: When molten solder temperature exceeds 500 ℃, it may produce steam, which may cause anemia, insomnia, weakness, constipation, nausea, abdominal pain and so on after inhalation. More severely, it may cause damage to central nervous system, reproductive system and digestive system.

Skin contact: it may burn the skin when melted in high temperature.

Ingestion: show a symptom of indigestion.

Hazard warning for environment: (blank)

Special harm: (blank)

Main symptoms: dizziness, headache, skin allergies etc.

Different first aid measures:

Inhalation: Inhalation of vapor may cause difficulty breathing. Take the sufferer to places where there is better air circulation and see doctor immediately.

Skin contact: Wash with soap water. If the skin is burned, cool it with cold water. If there are skin allergies, go to doctor for treatment.

Ingestion: see doctor immediately.

Main hazardous situation: (identical to Section 3 Hazard warning for health, Relevant Hazardous Information)

Protection of first-aiders: (blank)

Tips for the doctor: (blank)

Applicable fire extinguishers: CO₂, extinguishing powder or foam fire extinguishers. When they are used to put out the fire, avoid burning due to splashing of welding material with high temperature.

Possible special situation in fire-fighting: Molten alloy may cause severe splashing under high temperature with water, which may get operators burned.

Special protective equipment for firefighters: Firefighters must wear fireproof clothing and portable respirators.

Personal protection: Molten solder should be cooled to room temperature before treatment to avoid burning.

Environmental protection: Recycle leakage.

Methods for cleaning up: Scrape and recycle after cooling.

Disposal: Operating temperature should be less than 500 ℃. Operators should wear protective equipment to avoid inhaling vapor and dust. Don’t use dry brooms or spray high temperature gas in clean, because it may result in flying dust.

Storage: Storage should be waterproof, and anti-pollution. The package should be labeled with the identification of hazards.

Engineering control: Local ventilation and overall air regenerating devices should be installed to control exposure concentration lower than permissible concentration average.
