As dangerous as baby powder?
and your evidence of that is?
"Iraq mass produced sarin during the Iran-Iraq war with the expectation that it would be used quickly, and they therefore skipped several purification steps. Fresh agent was about 60% pure and heavily contaminated with hydrogen fluoride (which, of course, also causes health problems in exposed individuals). When production caught up with demand, the Iraqis started storing their sarin in refrigerated "igloos" to prolong its storage life. However, even when stored in the igloos, the material rapidly degraded, becoming less than 10% pure within 2 years."
