| Trade Name: | Elkaloy 42 | |
| Type of Product: | Cadmium containing brazing alloy. | |
| Nominal Composition: | Silver 42% | |
| Copper 17% | ||
| Zinc 16% | ||
| Cadmium 25% | ||
| Melting Range: | 608 - 617oC | |
| Potential Health Hazards: | The only potential health hazards involved with this product arise from its use. On heating, metal and metal oxide fumes may be evolved but are unlikely to exceed the stated OESs under normal conditions. However severe overheating could lead to the emission of fumes in harmful concentrations. | |
| The Health and Safety Executive in their Guidance Note EH40 list the following Occupational Exposure Standards (OESs) for metals commonly used in cadmium containing brazing alloys. | ||
| Long-term | Short-term | |
| (8 hour TWA value) | (10 min TWA value) | |
| Silver | 0.1mg/m3 | - |
| Copper fume | ||
| (as Copper) | 0.2mg/m3 | - |
| Zinc Oxide Fume | 5.0mg/m3 | 10mg/m3 |
| Cadmium Oxide Fume | ||
| (as Cadmium) | 0.05mg/m3 | 0.05mg/m3 |
| COSHH Regulations list the exposure limits for cadmium oxide as a MAXIMUM EXPOSURE LIMIT (MEL) which must never be exceeded. Short exposures to high levels of cadmium oxide can lead to pulmonary oedema and may be fatal. Prolonged or repeated over exposure to cadmium oxide fume is reported as causing renal damage. There is a symptomless latent period and any person thought to have been over exposed to cadmium oxide fume should be kept under observation for 48 hours. | ||
| Inhalation: | Metal fume fever can be caused by exposure to excessive fumes of copper and zinc oxides. 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. |
