The ICS symbols would mostly be used on printed local maps during emergency
incidents in North America.  The public safety government employees view
these maps.  They are generated and updated for distribution as part of the
IAP (Incident Action Plan) paperwork handout at each incident operational
period's personnel briefing, as the public safety personnel undertake their
emergency suppression work.

As you can see, they're mostly blue-colored circles or squares overlaid with
a upper case letter character.  Here (if this comes through) they are as a

The ICS symbols are not a standard but in common usage among certain groups
of the response community, primarily agencies involved in wildland fire

groups. The common symbols are generally consistent between groups, but
there are variations. For instance, the Coast Guard FOG contains some oil
spill and wildlife symbols that the fire groups do not have. 
 The ICS symbols in this standard that deviate from ICS practices are that
way due to a guiding principal of the Symbol Subgroup: avoid numbers and
letters in the symbols. This was meant to improve the intuitiveness of the
symbols and increase their usefulness for international applications and
support. The main exception to this rule is the use of an H in the hospital
ICS symbols can still resemble existing usage and conform to the standard by
using the correct opaque shape (Infrastructure/rectangle, Operations/circle,
etc.) and annotating the symbol as desired.
