Diazepam AKA Valium

[Nemo]

Learned something new today.   This stuff is frequently easily scriptable.   Good thing to have in case a batch of chemical warfare comes along.  Something that need more looking into on my end.

R&D, manufacturing and other products
RSDL

One of Emergent's medical countermeasure products is Reactive Skin Decontamination Lotion (RSDL), a lotion that clears and neutralizes chemical warfare agents. The product, used internationally, was tested in a study conducted by the US Army Medical Research Institute of Chemical Defense, where RSDL was found to provide superior protection against soman when decontamination was commenced within three minutes of exposure.[92] RSDL is made of the chemicals Dekon 139 2,3 butanedione monoxime (DAM). According to the Chemical Hazards Emergency Medical Management office within the United States Department of Health and Human Services, "RSDL is used as a medical device for the decontamination of skin exposed to chemical warfare agents such as sulfur mustard, VX, VR and certain biological toxins."[93] As of September 2017, RSDL is available to the regular public. Previously, it was only available to the military.[94]

The United States Department of Defense in September 2017 awarded the company a contract to supply the RSDL kit (RSDL) to the military. The contract is for five years and is worth $171 million. The RSDL lotion protects people's skin from various chemical warfare agents. The product contains a sponge that is filled with the decontamination lotion in and impermeable packet. When applied to the skin, the lotion reacts with the agent on the skin and quickly neutralizes it so that it becomes non-toxic.[95]
Auto-injector diazepam

The Medical CBRN (Chemical, Biological, Radiological and Nuclear) Defense Consortium, a DOD initiative within its Joint Program Executive Office for Chemical and Biological Defense has awarded the company US$20 million to develop an auto-injector to administer diazepam. The injection is designed to reverse the effects of nerve agents in military or chemical terrorism situations. The investment supports R&D, manufacturing and negotiating the approval process with the US FDA.[96] underline added

Never heard of a vallium injector to counter chemical agents.
Epinepherine ? Injectors - yes.
