What follows are things that haven't been able to fit into my other "Things that go boom!" story drafts.

So, I will combine them and make a separate story.

Over the years, the Core Four races developed a variety of equipment to carry and dispose of explosives. Some of this gear includes Explosion Containment Vessels (ECVs) that can be used to transport munitions or store suspicious objects.

Refer back to the story “Things that go Boom! Part 3: Expanding the Demolition Skill” for more information about TNT equivalent explosives. For example, Tornadium D-19 is four times as powerful as TNT, so a 250 gram charge is the equivalent of 1 kilogram of TNT.

Bomb Basket. The bomb basket is made up of non-fragmentation ballistic composite materials. It can be used as a safety ring, to minimize the impact of the fragmentation and sonic blasts. Each basket is mostly spherical shaped with a 1 meter diameter and has a fire-resistant, non-metallic holding net suspended inside. It is rated to it can deal with repeated explosions resulting from 200 grams to 1.2 kilograms of TNT.[1]

This type of ECV is typically rendered useless if the explosion exceeds its maximum containment level

Bomb Basket Accessories. Bomb baskets can be outfitted with specialized energy screens – such as inertia or sonic projectors – that are designed to absorb damage coming from inside the field rather than from outside. The field generators cost the same as a normal defense screen and are typically powered by a 50 SEU beltpack or a 100 SEU backpack.

The Vidar Series. The Vidar and Ladon lines are made by Eversafe Enterprises; they represent of the ECVs available in the Frontier. Vidar ECVs have tiny vents to allow pressure to escape in the event of an explosion, so they will not contain a gas or foam warhead explosion.

Named after the Norse god of mythology that survived the apocalyptic Ragnarök, the Vidar Series of ECVs is rated to containa blast up to a certain TNT equivalent weight. For example, the Vidar 3 is rated to handle an explosion up to 3 kilograms of TNT.

It takes 5 seconds to open or close the unit. The units can be equipped with locks. To break open the vessel from the outside, it has the same number of structure points as a security door(_____________).

Detonations that exceed the container’s rating risk cracking it, allowing blast damage to leak out. The Vidar may be able to withstand explosions up to double their rating, but they are not guaranteed to do so.  Most Eversafe units can withstand multiple internal blasts and still be usable.

Vidar 0.03. This square-shaped unit is for transporting small, suspect electronics. It also provides a Demolition specialist a safe way to store and transport explosives and detonators/blasting caps. The container is 400 centimeters (cm) long and wide plus 115 cm deep. It weighs 10 kilograms.

Vidar 0.5. This ECV is often used by laboratories for transporting pyrotechnic chemicals or by police officers for storing small suspicious objects. It is 71 cm long, 81 cm wide and 61 cm deep with an 24-by-17 cm rectangular opening. It weighs 150 kilograms and is often set in place, set on heavy-duty casters, or mounted on a vehicle or robot.

Vidar 1. This ECV is often used at airports, spaceports or other major transportation terminals for security officers to store suspicious objects. It is 93 cm long, 57 cm high, and 53 cm wide while weighing 200 kilograms. It’s opening hatch is 50-by-20 cm.

Vidar 3. This containment vessel is designed to safely remove or store large suspect pieces of luggage. The Vidar 3 is ideal for spaceport and public safety applications. It is 177 cm long, 150 cm wide, 172 cm tall, and weighs 1,600 kilograms. Its hatch is 76-by-55 cm.

Vidar 10. This vessel often is used as an in-house storage locker for explosives and small caliber ammunition. The Vidar 10 also serves as a way to store large suspicious objects. It is 223 cm long, 216 cm wide, and 200 cm tall and weighs 2,600 kg. Its hatch is 95-by-50 cm.

Vidar 15. The Vidar 15 ECV offers a convenient and cost-effective solution for an in-house storage location of explosives and small caliber ammunition. It can also be used to store large suspicious objects. It is 270 cm long, 315 cm tall,and 230 cm wide. It weighs 5,800 kg and has a hatch that is 95-by-50 cm.

Vidar 50. The Vidar 50 vessel offers a convenient and cost-effective solution for an in-house storage location of explosives and small caliber ammunition. Or it can store large suspicious objects. Its dimensions are 284 cm long, 386 cm tall, and 250 cm wide. The unit weighs 9,500 kg and its hatch is 110-by-60 cm.

 The Ladon-Gas Tight Series. Named after a legendary serpent dragon from Human mythology, Eversafe’s Ladon Series of ECVs will contain all types of explosions and comes with air sampling equipment.

These containment vessels are rated as gas tight (GT), meaning that they will not allow any potential nuclear, biological or chemical agents to escape as long as the explosion does not exceed the blast rating. Landons can withstand repeated explosions. They can be operated by remote control, robots, or manually.

Ladon-5GT. This containment vessel confines explosions of up to 5 kg (11 lbs.) of TNT equivalent. It further has a gas-tight capability of up to 2.5 kg (5.5 lbs.) of TNT equivalent. The Ladon-5GT withstands repeated detonations, The vessel is provided with an air sampling capability and is available with a trailer. It is a 200 cm diameter sphere and weighs 1,700 kilograms. It has a circular hatch that is 75 cm in diameter.

Ladon-8GT. This ECV contains repeated blasts of up to 8 kg (17.64 lbs.) of TNT equivalent. The gas-tight feature of the Ladon- 8GT permits responding permits responding demolition specialists to deal with explosives that might contain radiological, chemical or biological agents. The vessel is equipped with an air sampling system. It is a 250 cm sphere and weighs 2,300 kg. It has a circular hatch that is 75 cm in diameter.

Ladon-10GT. This detonation chamber contains blast effects of up to 10 kg (22 lbs.) of TNT equivalent. The Ladon-10GT’s gas-tight capability allows responding charactersto mitigate bombs that might contain radiological, chemical or biological agents. The vessel is equipped with an air sampling system. It is a 250 cm diameter sphere and weights 5,500 kg. It has a circular hatch that is 90 cm in diameter.

Ladon-50GT. This chamber contains blast effects up to 50 kg of TNT equivalent. Capable of withstanding repeated blasts, it has gas-tight capability and can be equipped with an air sampling system.-------------------- -------------- --------------

I'm also working on providing details for a couple of blast suits -- those worn by explosive ordnance disposal specialists. 

I need to create:
  • Details about how the energy screens can help the Vidar and Ladon ECVs contain blasts that are larger than their rating;
  •  Accessories for the Vidar and Ladon such as trailers and tool kits;
  • And then there should be a bomb disposal robot or two, including cheap drones.

Maintenance of Explosion Containment Vessels

After any explosion, an ECV should be inspected for structural cracks and component failures. They will also need to be cleaned out. Assume this process takes about an hour for the Vidars and Ladons that are rated for 5 kilograms or less. Add an extra hour for the larger units. 


Roll a d100. A result of 01-94 means that nothing significant is wrong with the ECV, cleanout costs were 3d10 Credits. A result of 95-98 means that a major repair is needed, The cost would be 2d100 + 200 Credits, taking 2d10 hours, if the character has access to repair equipment.


A 99-00 indicates that the contain vessel suffered a major structural failure. It cannot be safely reused. It can be scrapped, however, allowing the owner to recoup 10 percent of its purchase cost.
