Many explosive devices consist of a primary and a secondary explosive. The primary consists of a small amount of an explosive that is very easily set off. The primary creates a small explosion that sets off the secondary explosive, which consists of a material that is much harder to set off; usually a primary explosive is the only way. The secondary explosive provides most of the energy of the device, with the primary simply being a trigger. The use of primary and secondary explosives allows for explosive devices that are less likely to go off accidentally.

What is explosive mixture?
A mixture of substances that may explode under the right circumstances. Powdered flour dispersed thru air will explode if a spark is present. Gunpowder is an explosive mixture, not a compound. Nitroglycerine is NOT an explosive mixture. It is an explosive compound.

A secondary explosive device has been spotted. options describes how to proceed?
If a secondary explosive device has been spotted, immediately establish a safe perimeter to keep all personnel at a safe distance. Notify bomb disposal experts or the appropriate authorities for assessment and neutralization. Avoid any actions that could trigger the device and maintain situational awareness until professionals arrive. Follow all safety protocols and remain calm.
AWR-160-W Terrorism Awareness for First Responders answers?
The indicators of a secondary device are similar to those of an initial blast, though the initial explosion is the first warning sign. Personnel should always anticipate a secondary device when responding to an explosive incident. Indicators of possible criminal or terrorist activity involving secondary devices could include which of the following

What are the three categories of explosives?
Primary and secondary explosives. The definitions of these are rather loose, however typically primary explosives will detonate when ignited (example: mercury fulkminate), and secondary explosives require a shockewave to detonate (example: TNT). The most accurate definition is when used in the context of an "explosive train" whereby a fuse ignites the primary high explosive which undergoes deflagration to detonation transition, this detonation produces a shockwave which is used to initiate a secondary high explosive. So explosive compounds are classified into primary or secondary based there primary use.
What should one keep in mind upon arriving at the scene of an explosion and assisting victims and why?
Be on the lookout for innocuous containers such as parcels, crates, or backpacks. They may be used to disguise secondary explosive devices
