Friday chemical safety round up

The Safety Zone will be quiet the next couple of weeks while I’m on vacation. I’ll be back to attend David Snyder’s preliminary hearing in the UC Davis explosives case on July 26th.

But first, chemical health and safety news from the past week:

Fires and explosions:

  • Molten zinc was the source of a fire at a Ternium USA plant in Louisiana
  • A fire at Colonial Metals in Maryland was confined to the shipping and receiving area of the facility
  • A fire at waste company Pollution Control Industries in Tennessee “had no toxic chemicals burning, but the flammable chemicals storage area was well involved”; two employees and three firefighters were injured

Leaks, spills, and other exposures:

  • Assuming that the two leaks are the same thing, this story indicates that the “nitrogen” leak at Intel listed last week was actually nitrogen trifluoride
  • Methanol or ethanol spilled at Stanford in a hazmat storage area, I think in mechanical engineering

Not covered (usually): meth labs; ammonia leaks; incidents involving floor sealants, cleaning solutions, or pool chemicals; transportation spills; things that happen at recycling centers (dispose of your waste properly, people!); and fires from oil, natural gas, or other fuels

  1. What were shown in the Wired photos were cross-sections of cartridges. The bullet is the projectile. See I think the cartridges were disassembled and the powder removed before they were cut in half.

  2. Jyllian Kemsley inexplicably compliments the Newark Star-Ledger for its background concerning a murder by poisoning.† Yet the paper abides by a law, namely the conservation of ignorance. The Ledger repeatedly indicts as the poison elemental thallium, in a story as difficult to swallow as the metal would have been. Adding insult to injury, the paper also confuses a poison with a drug.
