 The teamwork in resolving this issue was excellent,  said Alcock.

 Everyone did their part to help control the checkpoint while we resolved the situation.

Brian Bushnell, TSA's federal security director for upstate New York's airports, said the incident serves as a reminder for travelers to check their bags before leaving home.

 Spent, inert or replica explosive items are not allowed through the checkpoint and can cause delays, disrupt operations and prompt a law enforcement response,  said Bushnell.

 When in doubt, travelers should leave the item at home or check TSA's resources, such as TSA.gov, before packing.

Though many people believe that spent grenades are not hazardous, officials warn that they can still pose risks.

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) has issued public safety alerts regarding vintage grenades in particular.

Recently, at Tampa International Airport, TSA officers discovered another alarming object.

TSA Officer Andrew Carter was screening the passenger's carry-on bag with an X-ray machine when he noticed something unusual about the flashlight - and flagged the bag for a closer look.

He ultimately found a 4-inch, double-edged knife concealed inside a baseball bat-shaped flashlight, according to an employee story published on the agency's website.

 Do not try to test the system,  Keith Jeffries, the Florida-based vice president of K2 Security Screening Group and a former federal security director for TSA at Los Angeles International Airport, told Fox News Digital about the knife incident.

 If you do, you will be caught.
