§ 209-a. Relations with other states and the dominion of Canada. 1.
Whenever a volunteer fire company or department of this state shall
answer a call for assistance from any political subdivision or territory
of another state of the United States, or of the Dominion of Canada, or
property ceded to the federal government, the provisions of section two
hundred five of this chapter and the provisions of the workers'
compensation law shall apply with respect to the volunteer firefighters
of such fire company or department, while such assistance is being
rendered or while going to or returning from the place from whence such
call came, to the same extent and in the same manner as if such service
had been rendered in the area regularly served by such volunteer
firefighters; provided, however, that there shall be deducted from any
amounts payable under such section or such law, any amounts recoverable
by or payable to such volunteer firefighters under the laws applicable
in the political subdivision or territory from whence the call for
assistance came.

2. The provisions of sections two hundred five and two hundred nine of
this chapter shall apply with respect to volunteer firefighters, fire
departments and companies of other states of the United States and of
the Dominion of Canada that render service in this state in answer to a
call for assistance, provided that the laws of the state served by such
volunteer firefighters, fire departments or companies, or of the
Dominion of Canada, as the case may be, contain provisions under which
substantially similar benefits are granted to volunteer firefighters,
fire departments and companies of this state when rendering service in
such other states, or the Dominion of Canada, as the case may be, in
answer to a call for assistance, and provided further that there shall
be deducted from any amounts payable under the provisions of section two
hundred five of this article to volunteer firefighters of such other
states or of the Dominion of Canada, any amounts recoverable by or
payable to such volunteer firefighters under the laws of the state
served by such volunteer firefighters or of the Dominion of Canada, as
the case may be.

3. The provisions of this section shall not apply where a volunteer
firefighter of this state, or of another state, or of the Dominion of
Canada, as the case may be, is killed or injured, on or after the first
day of March, nineteen hundred fifty-seven, or dies from the effects of
injuries received on or after such date.
