Many amateur radio projects use fiberglass tubing and there are some precautions you should take when handling it.
When the tubing arrives – before you open the box – be prepared. There may be fiberglass dust, slivers or particles present when the fiberglass parts were manufactured. Your best bet is to open the box outside, not in your dining room……
The use of typical fiberglass handling safety gear (gloves, dust mask, eye shield, clothing, etc.) when handling and working with fiberglass is highly recommended. Use a disposable damp rag to wipe the parts.
Do NOT use compressed air to clean fiberglass parts. The loose fiberglass particles and dust will fly all over the place.
When working with fiberglass, take precautions, especially when cutting or slitting the tubes. A hand saw or a power saw will make fiberglass dust. Wear protective gear to ensure you do not get any of the particles or dust in your eyes or in your hands. Wear a good dust mask to ensure you do not breathe in any of the particles or dust.
Measures can be taken to reduce exposure after a person has come in contact with fiberglass. Eyes should be flushed with water and any area of exposed skin should be washed with soap and warm water to remove fibers.
Clothing worn while working with fiberglass should be removed and washed separately from other clothing or just disposed. If you do wash the cloths, the washing machine should be rinsed thoroughly after the exposed clothing is done to ensure any loose particles are rinsed away.
Check with your local or state safety and/or environmental agencies for more detailed precautions. The easiest way to find out more information is to Google “Fiberglass Safety”.
