(WKOW) -- While the death of Transportation Security Administration officer Gerardo Hernandez has many talking about airport safety, TSA administrators are investigating whether to relax restrictions on liquids.

Since 2006, when authorities foiled a plot to blow up airplanes over the Atlantic with liquid explosives, travelers have been limited to 3.4 ounces of liquids or less in their carry-on luggage. 

Now, an Ohio-based company has developed a machine that can scan containers in 10 seconds or less using radio frequency and ultrasonic technologies. When it detects a suspicious substance, the machine is supposed to alert security. The company, however, does not give a margin of error, only saying that it's "very low," but can vary depending on the type of container, according to CNN.

London's Heathrow airport is taking the first step toward lifting liquids restrictions, setting a deadline for 2016. All European airports are to put liquid scanners into place by 2014.

In the U.S., a TSA spokesperson told CNN that lifting the liquids restrictions remains a long-term goal.

Former TSA administrator Chad Wolf says that the technology does not seem ready yet for full implementation.  

Tuesday morning, the TSA is to hold a memorial service for the 39-year-old officer, husband, and father of two in Los Angeles. Hernandez is the first TSA officer to be killed in the line of duty. U.S. Attorney General Eric Holder is expected to speak during the service.
