A very interesting article about the use of squibs on set appeared recently in the LA Times. You can read the full article here.

We at Squib FX have always known that there are many advantages to using our air powered squibs rather than traditional explosive squibs. Our squibs are more economic, easier to use, adjustable, and do not require special licenses or permits as old methods do. But the number one advantage that Squib FX rigs have over traditional squibs is safety. Without the risk posed by explosives Squib FX offer actors and crew a much less volatile experience when using squibs on set.

And as this article points out explosive squibs also contain LEAD DUST! Holy cow, like they weren’t dangerous enough!!
