DRRR S1F Q2
a in race
activate
rain
affects stability of land formations / provides water that loosens up earth materials
vertical
almost straight down
collapse
any material, fast, & limestone bedrock
subsidence
any material, slow, any bedrock
downward slope (landslide)
at an angle
during a fire we must be
attentive & quick
3 broad / common causes of a fire
carelessness with fire, electrical equipment failure, & lighting of fire material
2 types of vertical mass movement
collapse & subsidence
c in race
contain
possible causes of subsidence
depleted ground water & heavy structures
cool off heat
douse with water / use fire extinguisher
mass movement
downward movement of earth materials
e in race
evacuate
main causes of mass movement
gravity & water
components of the fire tetrahedron
heat, fuel, oxygen, & continuous chain reaction
3 characteristics of fire that makes it dangerous
hot, fast, & dark
stages of fire development
ignition/incipient, growth, fully-developed, & decay
3 properties that differentiate mass movement
material, speed, & unique property
2 ways to reduce fire risk
monitor / reduce fire hazards, & reduce fire vulnerability
debris / mud flow
muddy mix of materials, very fast, & preceded by floods or rains
fire code of the philippines of 2008
ra 9514
things to consider during a fire
race, cut off oxygen, cool off heat, & interrupt reaction
r in race
rescue
6 types of downward slope
rockfall, debris flow, avalanche, slide, slump, & creep
rockfall
rocky materials, fast, & occurs on rocky mountains
avalanche
snow, very fast, & occurs in temperate areas
slide
soil or rock material, slow to fast, & falls as blocks
slump
soil or rock material, slow to fast, & falls as layers
creep
soil or rock material, very slow, & can go undetected
cut off oxygen
stop, drop, & roll / cover burning object with sand
interrupt reaction
use fire extinguisher
2 types of mass movement
vertical (90º) & downward slope (<90º)
to prevent fires we must be
vigilant & careful
