Subject: Fw: [DCHAS-L] Chemical lists for schools
I've never bothered with subpart Z-1, the information I've needed has been
in the subsections I've listed.
While the dose makes the poison, the dose on water is significantly higher
than on highly toxic materials. From my high school memories, the
stockroom was WAY too accessible to have the inorganic cyanides, the DEA
precursors & essentials, any explosives (ammonium nitrate,
nitrocellulose), etc. just sitting out on the shelf with everything else.
If a stockroom decides to carry those items, they should be locked up in a
separate locked cage area.
Think about the example of the OTC psuedoephedrine products, which now are
required to kept behind the pharmacy counter, have limits on the monthly
purchase, ID required.. That's just to prevent their misuse in
synthesizing Crystal Meth. Based upon that example, sodium cyanide ought
not to be sitting on a shelf where anyone (students, faculty or other
staff) can access it. After someone gets poisoned is a pretty bad time to
decide that the stockroom security needs to be improved.

Re: [DCHAS-L] Chemical lists for schools
There are an awful lot of chemicals listed in Subpart Z: See Table Z-1:
Do you think it necessary to ban
Acetic acid ? (vinegar)
Ammonia? There're probably a bottle under the kitchen sink at home
Cellulose?
Isopropanol?
Clearly, confirmed carcinogens are not a good idea, but a blanket ban on
anything listed in Subpart Z is neither necessary or desirable.
In the right/wrong hands, ANY chemical can be deadly. Even distilled
water has an LD50. The dose makes the poison.
