The Package Can Be Dangerous!
Those of you whose school administrations allow the unsafe practice of “bidding” laboratory chemicals to continue will find an interesting example of trouble from “low bid” chemicals. Read the special hazard alert for calcium oxide and ask yourself whether your “low bid” chemical meets these safer packaging standards. None of our competitors package the substance to these standards. With bids, you get what you pay for!
