Most TCVs have two main modes: either gas tight or vented.

"For Mistral, this ranges from as little as 30 grams [1 ounce] of explosives to as much 45 kilograms [100 lbs.]." [Sept. 11 Anniversary: What the Attacks Taught Us About Science]
Top-vented containment vessels can also be used as trash cans in public places such as stadiums, hospitals, airports and shopping malls, Haber said. However, these trash cans are known as semi-confined vessels, meaning that they don't fully confine the explosion because they have an open top.
"Trash cans are considered soft targets, because the terrorist can walk up to them, put an improvised explosive device in them and walk away safely without raising any suspicion from anyone in the immediate area," Haber said. "Then, they can remotely detonate the device via cellphone, as we've witnessed in this recent
