If you’ve been entering Chemical Inventory records in CAMEOfm, you may have noticed that the Chemical Abstracts Service (CAS) number field remains empty after you link the record to the Chemical Database. In older version of CAMEO, this information was filled in for you when you created the Chemical Inventory record. Not so in CAMEOfm.
At present, there are only two ways to get CAS numbers to appear in CAMEOfm Chemical Inventory records:
Note: If you find that you must enter the CAS numbers manually, you may encounter an error message telling you the number is incorrect. This is because CAS numbers are specially constructed so thatonly certain number combinations are valid. If CAMEOfm advises you that the number is incorrect, it almost certainly is. In such cases, you should verify the number with the source that provided it to you.
Here are some tips to help you get more out of CAMEOfm. They're PDF files so you’ll need a copy of the Adobe Acrobat reader.
EPA and NOAA offer advice on setting up CAMEO, MARPLOT & ALOHA: http://www.epa.gov/oem/content/cameo/vista.htm.
Here are some tips to help you get more out of MARPLOT. They're PDF files so you’ll need a copy of the Adobe Acrobat reader.
Lewis Blumstein of Excalibur Associates, Inc. in Colorado has prepared an Excel spreadsheet that can be used with ALOHA to calculate plume footprints for solutions. (Normally, ALOHA will only give results for pure chemicals.) With his permission, we've posted it for others to use.
The spreadsheet is based upon the approach described in the publication: Modeling Hydrochloric Acid Evaporation in ALOHA, Report No. HAZMAT 93-3, by Mary Evans, dated 7/93. We encourage you to download and read the report if you intend to use the spreadsheet.
If you find the spreadsheet useful or just want to comment on it, e-mail Lewis Blumstein.
NOAA has posted a new item on their web site. It is an on-line calculator that will allow you to calculate the evaporation rate from pools of certain aqueous solutions. Right now, the calculator works for the following: Aqueous Ammonia, Formaldehyde, Hydrochloric Acid, Hydrofluoric Acid, Nitric Acid, Oleum, and Sulfuric Acid.
To try the calculator, go to http://response.restoration.noaa.gov/cameo/evapcalc/evap.html.
