"It looks like it was a timing issue," Whelan said yesterday. "They didn't wait long enough to read the test.
"This sort of thing has already happened in several other areas across the country where they're using the same equipment."
Whelan said the device, the Guardian Biothreat Alert, or Guardian BTA, needs 15 minutes to properly screen for biological agents including anthrax, Ricin, botulinum toxin, plague and staphylococcal enterotoxin B, otherwise known as SEB. The results appear on a test strip, much like some home pregnancy tests, with two bands across the test strip indicating a positive result while one band indicates a negative result.
Whelan said that while Hazardous Materials crews may have gotten false results at first using the unit in "manual" mode, they did follow instructions that say another test in "automatic" mode should be run to confirm the results.
"From what I understand they (HazMat crews) did run our instrument twice in manual mode and got positive results," said Whelan. "Then they ran it in automatic mode and got a negative result."
