CAMEO Instructor’s Certification Exam

The concept of a CAMEO Certification Exam is to test a person preparedness to be an effective instructor of the CAMEO Suite.   At a minimum, a Certified CAMEO Instructor should demonstrate an in-depth understanding of all the various components of the CAMEO Suite (CAMEOfm, ALOHA, MARPLOT, CAMEO Chemicals) and the integrated operation of the Suite components.  Additionally, a Certified CAMEO Instructor should be familiar with HazMat information, with NIMS and other typical Emergency Management standards, and with a variety of standard computer terminology and operations as those apply to the CAMEO Suite.

It is a requirement that applicants to the CAMEO Certification Exam must first pass the CAMEO User’s Exam, thereby negating any need for the Certification Exam to test an applicant’s ability to utilize the CAMEO Suite for standard operations.  Topics such as retrieving and understanding chemical data, interpreting CAMEOfm Tier 2 and other module information, ALOHA source models and threat zones, and MARPLOT mapping capabilities will be tested in the CAMEO User’s Proficiency Exam.


Exam Topics:

  • Installation and setup of the CAMEO Suite
  • CAMEO Chemicals
  • CAMEOfm
  • Integrated Operations of the CAMEO Suite applications
  • Interacting with other software applications
  • Troubleshooting
  • General computer knowledge as applied to the CAMEO Suite



The exam will consist of 50 multiple choice questions covering the four software applications (CAMEO Chemicals, CAMEOfm, ALOHA, and MARPLOT)






Installation and setup of the CAMEO Suite

  1.  directly to the c: drive
  2. in the c: drive, My Documents folder
  3. in the c: drive, Program Files directory
  4. to a special directory on the c: drive named “CAMEO”


A standard installation of the 4 CAMEO Suite applications writes places the CAMEO SitePlans subdirectory in:

  1. C:\CAMEO\Siteplans
  2. C:\Program Files\CAMEO\SitePlans
  3. C:\Documents and Settings\All Users\Shared Documents\CAMEO Data\SitePlans

CAMEO Chemicals


Which of the following statements about CAMEO Chemicals is True?

  3. Only the stand-alone version of CAMEO Chemicals will link to ALOHA and  CAMEOfm
  4. All the above statements are True


The Reactivity Worksheet predicts reactions only for 2 substances at a time.  One reason for this is:

  1.  not all RIDS substances are reactive
  2. the Reactivity Worksheet cannot account for potential catalysts
  3. water vapor in the atmosphere may alter the reactive predictions if more than two chemicals are involved
  4. predicting reactions involving more than two substances requires more computer processing speed than most personal computers have available

  1.  Chemical name
  2. CAS number
  3. UN/NA number
  4. Reactive Group

  3. ALOHA does not have vertical dispersion capability
  4. Do both answers a. and b

  1. Puddle radius shrinks over time as the puddle evaporates
  2. Puddle radius increases over time as more product escapes the vessel or containment and enters the puddle
  3. Puddle radius remains constant over time regardless of any external events
  4. Both answers a. and b. are correct




Relocating a MrSID or Geotiff file on the host computer following a successful “Add Layer” basemap import of the file will result in loss of the raster display in MARPLOT.  To recover the display of the file, one may:

  1.  Go into the global map file and reset the pathway
  2. Go into the MARPLOT folder and run the reindex.bat file
  3. Use the Basemap Builder to import the file from the new location
  4. Copy & paste the raster file into the MARPLOT Maps\BasemapFiles\Basemap\Images folder

To preserve an existing ALOHA Threat Zone on the MARPLOT display prior to altering the release conditions in ALOHA, a user may

  1.  Use the MARPLOT “Make New Polygon” operations
  2. Move the group of ALOHA objects to a different MARPLOT overlay
  3. Use the MARPLOT “back” button to view the previous ALOHA Threat Zones
  4. Set the File / Preferences menu to “Save ALOHA Objects”


Entering a different Latitude / Longitude value to a CAMEOfm record that is linked to a MARPLOT object will:

  2. Terminate the existing link between the CAMEOfm record and MARPLOT object
  3. Have no effect on the position or linkage of the record and object
  4. It is impossible to enter a different Lat / Long to a linked CAMEOfm record without first repositioning the associated MARPLOT object


Interacting with other software applications


A portable GPS unit will typically output user-collected “waypoints” as a .txt file containing three fields of information; Latitude, Longitude, and Object Name.  Data such as this may be Imported to MARPLOT via spreadsheet operations, such as EXCEL.  The user must prepare a spreadsheet with the Latitude, Longitude, and Object name, along with all but one of the following:

  1.  Object ID number
  2. Overlay name

  2. Rename the .txt file extension to .doc or .xls
  3. Enter .doc or .xls as the file extension during the CAMEO Chemicals export process
  4. Any of the above




While Importing a MARPLOT .mie or .txt file, an error message stating ‘MARPLOT encountered an unrecognized constant at line 52′ is displayed.  This message means:

  1. all of the data was imported, but with errors
  2. none of the data was imported
  3. all import data after line 52 of the import file was truncated
  4. all of the data was imported, but all data after line 52 will have errors


While attempting to add information to a CAMEOfm record , a message box appears stating “Your access privileges do not allow you to perform this operation”.  To correct this problem, the user should:

  1. set the user security rights on the CAMEOfm folder to “full control”
  2. select the Edit hot button from the CAMEOfm button row
  3. exit and re-launch CAMEOfm
  4. use the Edit menu to open the CAMEOfm record


While attempting to copy and paste a number into the CAMEOfm Latitude or Longitude fields, a message box appears stating “This field to defined to contain numeric values only.  You must enter a numeric value”.  The most likely cause for the message is:

  1. the user does not have Edit rights
  2. the number being pasted is not within acceptable Lat/Long coordinate values of -90 to  90 for Latitudes and 180 to -180 for Longitudes
  3. the source file has the number formatted as text or general
  4. the Latitude or Longitude number does not match the Street Address field for the CAMEOfm record being edited
