hazards
- bio contamination. Diseases, sewerage, toxic chemicals. Could get sick
- deecomtamination, washoff
depth current and flow
- difficult to determine
- 30cm enough to knock you off feet
- risk → washed away - >control → dont nter fast flowing flood water, maintain safee distance
below surface debris
- eg fences and infrasture
- risk → become entangled/entrapped, injury, impalement → control → do not enter flowing flood water, maintain safe distance
ssurface debris
- trees and rubbish float or gather against structures
- risk → entangeled → control → do not enter flowing flood water
hydrolics
- objects in and under water affect flow
- risk → rough water → do not enter flowing flood water
wirs, culverts and causeways
- ppl, cars boats can wash over
- risk → held (recirculated) in weir → do not enter flowing flood water
drains
- urban drain into underground/road system
- risk → force of water drag person into drainage system
power of flowing water
- 2x speed = 4x force
- 30cm
post flood damage
- damage roads and bridges → unsafe to drive on → ensure approved to travel on
working near flood waters
- unstable banks → maintain distance, wear pfd
vegetation → snags, stings → maintain safe distancee → wear corrct ppe, pfd → avoid running and pay attention to wear you put your feet
dangerous insects and animals
- flood waters and debri and veg can contain animals
- risk → bite/sting → wear ppe apply insect repellnt
poor light
- increases difficulty in id hazards
- trips, slips, falls → maintain radio/hand/whistle comms
noise
- noise inhibits comms
- risk → mis instructions → maintin comms. Use hand, whistle
hazards
- fast moving watrs, vehicle swept off cause way, large animals (unpredictable), public/untrained rescuers, working alone
- reach → force of water pulls rescure in
- throw bag → force pulls in
- wade → force loose traction
Module 4
first in scene:
call 000
asses risk
control risk (move ppl away from bank)
asses watr conditions (velocity, debris, hazards)/person
liaise with othr services
determine if ppl are undertaking rescue without pfd
put on pfd in prep for support task
prep for night (well lit, torches)b
safe working areea
cold zone (flood rescue awareness)
warm zone (land based, in -water, on water)
upstream spotters
land based ops
downstream
hot zone (in water)
upstream spotter
keep lookout for ppl, debris
warm zone or safe structure
flood rescue operator land based
- warm zone
- assist using talk, rach, throw, wade, and no
- upsteam spotter
on-water
- warm and hot zons
- talk, reach, throw, wade, row, and no
- boats and rafts, transport, re-supply, inland water search and body recovery
in-water
- warm and hot zons
- talk, reach, throw, wade, row, go, and no
- boats, rafts, rescue from flooded vehicles
rope based teech, tension diagonals, highlines, tethrd boat
defensiv swimming
- float on back with feet downstream
- protect head
- use hands and feet to fend
tips
- dress down
- no firefightinfg ppe, harnss ropes
communication systems
- establish sig’s via radio or phone, to warn persons in operationss area
- if dont understand hand sigs keeps arms low with palms towards signaler
- give same sig back as ack
- OK
- arm on head with elbow to side
- STOP – arms out wide
- EMERGENCY – wave arms over heead
