[ICOM] Emergency radio ICOM

[Anna ostensson]

Hi!
 
The Safety department at my company has asked me to buy four radios (i.e. walkie talkies) to put in an Emergency Response kit. I've been looking around and ICOM seems like the best options.
But I'm still a bit lost. I need 4 "walkie talkies" that could be used in case of fire, explosion or any other big emergency. The biggest problem is that they have to work the facilitie's underground rooms..
What should I buy...? Hopefully we will never need to use them so they shouldn't be the most expensive one available on the market but they still have to work well if anything happens... 
 
Thanks in advance!
