 Knight Lab

## People

You need to know these people's names for the Level III inspections.

• EHS representative: Reshma Shetty (rshetty AT mit)
• EHS coordinator: Anthony Zolnick (anthony AT csail)
• EHS lead contact: Carolyn S. Stahl, SM(NRM), CBSP (csstahl AT mit)

Carolyn S. Stahl, SM(NRM), CBSP Senior Biosafety Officer
MIT Environment, Health and Safety Office

fax: 617-258-6831

## Information and training

See Heather's very complete explanation of all the safety training you need to do. The only adjustments for the Knight lab are that you should read the CSAIL chemical hygiene plan (not the Biology one) and you should do the Knight lab specific chemical training. Both of these are linked below.

### General safety resources

Much of the labs safety references including MSDS's (Material Safety Data Sheets) are kept on the short bookshelves in the hallway between 32-311 and 32-321.

Heather has written up a lot of useful safety information here.

EHS course materials can be found at http://web.mit.edu/environment/training/materials.html

### CSAIL emergency preparedness plan

• includes floor evacuation maps and an explanation of the Stata Alarm system

### CSAIL chemical hygiene plan

Everyone in the lab has to read through the CSAIL Chemical Hygiene Plan. It is linked below and also available as a paper copy on the shelves in the hallway between 32-311 and 32-321. To make changes to the document, contact Meagan Lizarazo.

CSAIL Chemical Hygiene Plan <--Read and familiarize yourself with this.
(Template from Barry Mendes, EHS, x3-1665. Modified and extended by Meagan.)

Once you've read this document, print and sign the compliance form. Give this to Meagan to be sent via campus mail to the EHS lead contact Carolyn Stahl.

### Lab chemical training

If you've never had lab specific chemical training before, have Tom or Reshma take you through it. For renewal training (done on a yearly basis), you can just read through the lab specific chemical training linked below. It is also available as a paper copy on the bulletin board outside 32-306 and on the shelves in the hallway between 32-311 and 32-321. If you have any questions or want to suggest modifications, talk to Reshma.

## Procedures

MIT's standard operating procedures on a variety of topics can be found at the EHS SOPs, SOG, Fact Sheets, Programs, etc. site.

### Waste disposal

Some brief instructions on how to properly dispose of waste in the lab.

### Chemical storage

#### Acetic acid and other organic acids

From Kathleen Gilbert, EHS, x3-8409

Acetic acid is tricky because it is an organic acid that is ignitable and it is more compatible with other organic flammables than with inorganic acids. Acetic acid can be stored with the flammables in a flammable cabinet without a secondary container. If Acetic acid is stored with inorganic acids, it should be in a separate secondary container since it is incompatible with inorganic acids. Trifluoracetic acid is also an organic acid so the same rules apply as with acetic acid.

You do not need the acids stored in a closed [secondary] container. A gray bin is fine.
