for a rather inconspicuous package, a Leatherman juice s2 (or Vic Farmer),single cr123 Streamlight (110 lumen)light, metal whistle, and firesteel will fit in a generic multi tool pouch... bandana, and a couple of R95 or N95 masks (you could probably vacuum seal them into a pocketable size), and foldable water storage pouch (wallet)could easily round out the ensemble and not look out of place on the job
