I was reading the element collection thread and just discovered the ability of Gallium to melt at 86C. Descriptions said you could hold it in your hand and watch it melt!! Checking out the MSDS, I got a much different description...

 

http://www.espi-metals.com/msds's/gallium.pdf

 

"SKIN: In case of contact, immediately wash with soap and plenty of water for at least 5 minutes. Remove contaminated clothing and shoes. Thoroughly clean contaminated clothing and shoes before reuse. Get medical attention if irritation develops or persists."

 

Does anyone have personal experience with handling Gallium?

 

Is it actually safe to play with for an extended period?

 

Are there any other kewl metals/elements that are safe to handle but have prudent MSDSs such as this?

 

Thanks,

MSDS can be quite deceptive, try the MSDS for Sodium Chlorine (table salt!) you'll find that it will cause cancer, care should be taken to avoid skin contact, wash hands with soap and plenty of water etc. I've handled gallium quite extensively, and personally know of people who have actually intentionally swallowed up to 10 grams of gallium without any side effects. Gallium is even considered a nutrient, is used in medics as a scan (gallium is injected in the blood stream). So it's totally safe to handle gallium! even water can be toxic if you drink huge amounts! just keep your wits, and you're totally fine.
