PRODUCT SAFETY DATA 1.

IDENTIFICATION OF SUBSTANCE 18W Gold Solder 750W2

Date 04/15 Sales code PP3 300 Issue No. 1

2.

COMPOSITION A gold solder alloy composed of gold, nickel and zinc. The precise composition of this alloy is confidential information.

3.

HAZARDS IDENTIFICATION The only potential health hazard involved with this product arises from its use. On heating, metal and metal oxide fumes may be evolved but are unlikely to exceed the stated OES’s under normal conditions. However, severe overheating could lead to the emission of fumes in harmful concentrations. Metal fume fever can be caused by exposure to excessive fumes of zinc oxide. Symptoms are similar to those of influenza and often appear after a latent period of up to 10 hours. They normally disappear after 24 hours with rest.

4.

FIRST-AID MEASURES Metal oxide fume can be irritating to the upper respiratory tract, nose and throat. In powder form metal dust will irritate the eyes and is harmful if ingested. Inhalation:

Fumes may be evolved at brazing temperatures, which will irritate nose, throat and respiratory organs. Remove patient to fresh air. In acute cases apply artificial respiration and summon medical aid.

Ingestion:

Not applicable. However if the alloy in powder form is ingested, rinse mouth with water and give patient water or milk to drink. Do not induce vomiting. Summon medical aid.

Eyes:

Not applicable. However, if the alloy is in powder form and dust gets into the eyes, irrigate with water or isotonic saline for up to 20 minutes. Seek medical attention if there is any hint of eye damage.

Skin:

Wash hands with soap and water after handling brazing alloy. If any skin irritation develops, seek medical advice.

5.

FIRE FIGHTING MEASURES Non-flammable. Use extinguishing medium suitable for surrounding fire but exercise care with water if molten metal is present.

6.

ACCIDENTAL RELEASE MEASURES Material may be collected for re-use or scrap as required. If alloy is in powder form avoid getting dust in the eyes or breathing metal dust.

7.

7.1

HANDLING Use in a well-ventilated area with local extraction systems. Do not inhale any fumes evolved during use. Wash hands thoroughly with soap and water after handling the brazing alloy, particularly before eating or smoking.
