i ne Tottowmg taoie is userui not only Tor storing cnemscais saTe!y, out also Tor placing cnemicais in
<br /> boxes or bins for disposal. As most high schools do not have frequent pickup of hazmat materials, old
<br /> chemicals must sometimes be set aside for up to a year until pickup occurs. Consult this table to
<br /> det-ermine which chemicals may or may not be stored together. Download the full list of incompatible
<br /> Chemicals in PCF.

<br /> Chemicals that cannot go down the drain
<br /> There are several chemicals that absolutely SHOULD NOT go down the drain:
<br /> ■ Halogenated hydrocarbons (chlorofluorocarbons, chlorocarbons, etc.)
<br /> • Nitro compounds (nitroethane, nitrobenzene, etc.)
<br /> • Mercaptans, also known as thiols (methyl mercaptan/methanethiol, etc.)
<br /> • Flammables immiscible in water(hexane,toluene, etc.)
<br /> Explosives (azides, fulminates, etc.)
<br /> Water-soluble polymers (sodium polyacrylate, guar gum, casein, etc.)
<br /> ti Water-reactive materials (lithium, sodium, and other alkali metals)
<br /> Chemica's with a foul odor
<br /> ■ Toxic chemicals (carcinogens, mutagens,teratogens; indicated on SCS)
<br /> • Substances with a boiling point lower than 50 °C
<br /> • Insoluble solids, including hair, ash, sand, metal, or glass
<br /> • Ci! or grease
