A statemment<br />
concer rning the rissk<br />
of fatal in njuries in the<br />
different industries therefore<br />
is not poossible.<br />
In orderr<br />
to relate thhe<br />
fatal injuries<br />
to the ttotal<br />
workin ng time and hence to thhe<br />
value added,<br />
the<br />
workingg<br />
time for eevery<br />
industry<br />
has to be available.<br />
For the reasons exxplained<br />
in the last<br />
paragraaph,<br />
values should no ot be drawnn<br />
from diff ferent sourc ces. So vaalues<br />
from different<br />
tables, generated based on th he source mmentioned<br />
above on non-fatal n annd<br />
fatal injuries,<br />
are<br />
used: TThe<br />
total woorking<br />
time for each inddustry<br />
is de erived from the non-fattal<br />
injuries rate and<br />
from thee<br />
absolute nnumber<br />
of non-fatal n injuries.<br />
3.9 SSocial<br />
Proofile<br />
of the e industryy<br />
The soccial<br />
profile ffor<br />
each ind dustry includdes<br />
the wo orking time in different qualification<br />
levels,<br />
the non-fatal<br />
and the<br />
fatal inju uries, each related to one o Euro of f value addeed<br />
generate ed in the<br />
respective<br />

Prices forr<br />
<strong>GaBi</strong>-Flows<br />
For relaating<br />
the social<br />
data to o LCA proceess<br />
data, th he value added<br />
of eachh<br />
LCA proc cess has<br />
to be iddentified.<br />
Thhis<br />
is done by calculating<br />
the delta<br />
of prices<br />
between the output and the<br />
input floows<br />
of eachh<br />
process. Therefore, for all mate erials, intermediate<br />
prooducts<br />
or products, p<br />
as well as variouss<br />
energy fl luxes, whicch<br />
go in an nd out of processes, p prices hav ve to be<br />
determined<br />
and asssigned.<br />
Sin nce the prooduct<br />
prices s depend on n a dynamicc<br />
market, th he same<br />
referencce<br />
period ffor<br />
both the e prices annd<br />
for the identificatio on of the vvalue<br />
added d of the<br />
industriees<br />
should be selected d. In this ccase<br />
the calculation<br />
is<br />
made wiith<br />
annual average<br />
values oof<br />
the same<br />
reference e period. A foreign trade<br />
statistic is used to provide co onsistent<br />
price daata<br />
(U.S. CEENSUS<br />
BURE EAU 2002A, U.S. CENSU US BUREAU 2002B). 2<br />
For moost<br />
of the fflows,<br />
price es can be calculated regarding quantities and total value v of<br />
exported<br />
commodiities.<br />
In cas ses where tthis<br />
is not possible, p pr rices are esstimated<br />
pe er expert<br />
judgemeent<br />
using tthe<br />
assump ptions that tthere<br />
are no n negative e value adddeds<br />
and th hat price<br />
ranges can be esttimated<br />
on the basis oof<br />
the lowe er price of a preliminaary<br />
product and the<br />
higher pprice<br />
of a suubsequent<br />
product. p This<br />
kind of es stimation ha as an impacct<br />
on the res sult if<br />
1. tthe<br />
according<br />
flow pas sses from onne<br />
industry into anothe er industry aand<br />
2. tthe<br />
social pprofile<br />

3.11 VValue<br />
Addded<br />
of GaB Bi-Processses<br />
In orderr<br />
to calculatte<br />
the value added of a single proc cess, the to otal value off<br />
the incoming<br />
flows<br />
is subtrracted<br />
fromm<br />
the total value of thhe<br />
outgoing g flows of a process. The total value is<br />
calculatted<br />
by multiplying<br />
the amount of the flow wi ith its price and then bby<br />
summing g up the<br />
values oof<br />
all flows.<br />
