Agent Characteristics
Mycobacterium smegmatis
mc2 155
Bacteria
  Yes        
Acid-fast, fast-growing, non-motile member of the nontuberculous mycobacterium complex. It is an uncommon human pathogen. It is found in soil and water, and due to its thick cell wall, it is environmentally stable and resistant to many disinfectants as well as some anti-tuberculocidal drugs such as isoniazid and rifampin.

> 65 °C for at least 30 min; Autoclave at 121 °C for 30 minutes
M. smegmatis is able to survive in the environment and is found in soil and water.
PPE/Containment
Wear gloves and appropriate lab attire (pants/long dress, closed toed shoes); eye protection, e.g. safety glasses, safety goggles recommended for liquids. Additional PPE may be required depending on lab specific SOPs for handling Mycobacterium smegmatis.
Spill Procedures
Notify others working in the lab.  Allow aerosols to settle. Don appropriate PPE.  Cover area of the spill with paper towels and apply an EPA approved disinfectant, working from the perimeter towards the center.  Allow 10 minutes of contact time. Cleanup spill materials and dispose as biowaste. Surface disinfect 5-10 minutes. Remove PPE and wash hands.
For large volume spills or biological spills in a public area, contact MIT's Biosafety Program or the EHS office (617-452-3477) during normal business hours.  If the spill occurs after hours or on weekends, activate the EHS ON CALL system by dialing Operations 3-4948 (617-253-4948) or MIT Police by dialing 100 from a campus phone or 617-253-1212 from a mobile phone.
Exposure Procedures
Flush eyes, mouth, or nose for 15 minutes at eyewash station.
Wash area with soap and water and rinse/scrub for 5-10 minutes.
Immediately report incident to supervisor, PI, or EHS Representative. PI/supervisor must submit incident report in Atlas within 24 hours.

When you bring additional fields into a conversion, Quickbase often finds inconsistencies. For example, say you're converting your Companies column into its own table. One company, Acme Corporation, has offices in New York, Dallas and Portland. So, when you add the City column to the conversion, Quickbase finds three different locations for Acme. A single value in the column you're converting can only match one value in any additional field. Quickbase needs you to clean up the extra cities before it can create your new table. To do so, you have one of two choices:

  • If you want to create three separate Acme records (Acme-New York, Acme-Dallas and Acme-Portland) click the Conform link at the top of the column.
  • If the dissimilar entries are mistakes (say Acme only has one office in New York and the other locations are data-entry errors) go back into your table and correct the inconsistencies—in this case, changing all locations to New York. Then try the conversion again.
