Basic public safety measures
each project should be reviewed for public safety needs on a case-specific basis. it is extremely
important to assess the number and type of public safety measures at any project based on the
public use patterns at a project. projects that do not have significant and documented
recreational use may, for instance, require only nominal public safety measures such as proper
signing. the following is a partial listing of public safety measures that should be considered
when undertaking a case-by-case review of public safety at a project (reference figure 1
[appendix 1]):
1.
boat restraining barriers upstream of overflow, gated, flashboard (or rubber dam) and
needle beam spillways, powerhouse and canal intake areas, and upstream of natural
channels that extend to project structures.
waming signs in tailrace areas.
clearly visible and legible warning signs an appropriate distance upstream of and facing
the reservoir of each dam.
fences at substations and restricted access to hazardous areas around dams and other
project structures.
audible waming devices, together with signs to explain their meaning, at those projects
with sudden changes in operation that result in large flows and rapidly changing tailwater
levels.
restricted public access to powerhouses, intakes, and other operating structures.
if necessary, canoe kayak portage signs and routes at projects where canoeists and
kayakers require portage around the dam. (note: kayakers should be prohibited from
traversing over dams).
if determined necessary, signs (at least one) facing the reservoir on each dam with a
hazardous spillway, with lighting for night time visibility.
can you me summarise what this is saying
