Nerve gas antidote syringes could be carried by Lincs paramedics to help people in the event of a terrorist attack.
The county's ambulance service has taken delivery of the pen-like devices, which can fit into a shirt pocket.
Ambulance service bosses are to decide whether to keep them in a central store or stock ambulances with them.
They said the government sponsored initiative was a "sensible precaution" against possible attacks.
Gordon Hiles, emergency planning officer for Lincolnshire Ambulance Service, said: "It's just been issued as a sensible precaution.
"It's the same as somebody might have a fire extinguisher in their office, so if anything did happen we would have some means of dealing with it.
