PECULIARITIES OF HIGH ALTITUDE

Rarified Atmosphere

Low temperature

High Ultra Violet Radiation

Harsh Terrain

Extreme Precipitation

PECULIARITIES OF HAA

RARIFIEDATMOSPHERE

RARIFIED ATMOSPHERE

Low pressure of oxygen

Decreased density of air

Low Atmospheric pressure

RARIFIED ATMOSPHERE: EFFECT ON HUMANS

Reduced oxygen supply to body tissues

Headache / Nausea / Fatigue / Appetite loss

Muscular weakness / Loss of night vision

Loss of memory / Sleeping disorders

AMS / HAPO / HACO

Acclimatisation

RARIFIED ATMOSPHERE: EFFECT ON AIRCRAFT

Change in aerodynamics

Reduction in power, thrust & lift

Reduced maneuverability

Lower climb rate / Longer take off

Hovering (helicopters) is difficult

Reduced load lifting capacity

AIRCRAFT CAPACITY

At Sea Level – 30 persAt Leh (350 C) - Nil

MI-17

At Sea Level- 400 persAt Leh (250 C) - Nil

IL-76

RARIFIED ATMOSPHERE: EFFECT ON VEHICLES

Reduced efficiency

Loss of engine power

Excessive smoke in vehicular exhaust

Increase in fuel consumption

Reduced load carrying capacity

LOWTEMPERATURE

PECULIARITIES OF HAA

LOW TEMPERATURE

Further deterioration by ‘wind-chill’ effect

Temperatures as low as -300 C

Temperature decreases with altitude

LOW TEMPERATURE : EFFECT ON HUMANS & ANIMALS

Physiological shock

Hypothermia

Frostbite

Need for special clothing / food

LOW TEMPERATURE : EFFECT ON AIRCRAFT, VEHICLES & MACHINERY

Freezes Fuel Oil Lubricants

Makes metal parts brittle

Starting problems

Need for special additives / care

HIGHULTRA-VIOLET

RADIATION

PECULIARITIES OF HAA

HIGH ULTRA-VIOLET RADIATION

Increases by 12 % for every 1000m height

Causes high ionisation

Polymers, paints & dyes: Degradation

Skin: Sunburn, Premature aging, Cancer

Eyes: Snow blindness, Cataract

Special protective gear required for humans

HARSHTERRAIN

PECULIARITIES OF HAA

HARSH TERRAIN

Narrow valleys with high peaks

Ridgelines- far away

Rocky narrow roads

Fog / Changing winds

Choke points – bridges, passes, defiles

Distances calculated in time

TERRAIN: EFFECT ON MEN & MACHINES

Few airstrips / helipads / dropping zones

Flying difficult in narrow valleys

Drastic reduction in vehicular speed

Limited approaches by road & air

Move on foot is extremely exhaustive

EXTREMEPRECIPITATION

PECULIARITIES OF HAA

EXTREME PRECIPITATION

Rain

Snow

Fog

Thunderstorms

Either excessive / reduced• Excessive – Uttarakhand, Kashmir, NE India• Reduced - Ladakh

CYCLE

Construction Activity• Takes time• Only in summer months

Wooded areas at High reaches• Fire Lanes• Only when not under snow or heavy rain

Prevention

Legal Aspect• Disaster Management in Master plans• Construction of houses as per specifications• Proper Road Construction

Hazardous Material, Fuel, Chemicals• Decentralised Stocking

Early Warning System• Unattended• Robust• Reliable

Mitigation

Advance Winter Stocking• Annual road cut off period• Potential cut off sites e.g bridges, crossing

pointsAb initio Construction• Helipads, Airstrips, Communication, Power

Backup• Adequate redundancy

Facility Locations• Decentralised• Locations chosen with due modeling

Updated Population & Tourists Records

Preparation

Pin point affected areas• Helicopters / UAVs / Satellite Imagery

Collection of data• Affected populace / Survivors

Restoration of Communication• Road/ Air/Tele

Debris removal• Low efficiency of machines• Reduced human effortAcclimatise Search & Rescue teams

Response

Restoration takes time• Little construction period• Food & medical priorities

Time only to raise temporary shelters• Pre-fabricated

Supply Chain for Stores• Stores as per priority• Selected mode of transportation• Stocking space pre-identified

Recovery

Master Plan- Regulated & controlled

Disaster Management aspects incorporated ab-initio

Specially designed Infrastructure

Development Activities should not add to potential disasters

MAJOR ACTIVITIES

Identify potential disaster sites

Evacuation Pre Positioning

• Evacuate Casualty

• Distribute Relief

• Extricate displaced persons

Road Comn

• Build houses

• Generate employment

TYPE OF SUPPLY CHAIN

Business Supply Chain Disaster Response Supply Chain

Business Supply Chain

SUPPLY CHAIN MODEL

Business supply chain – Minisum•Time not a high priority•Cost is paramount•Aim - Minimise the sum of cost of logistics

Disaster supply chain - Minimax•Relief supplied fastest•Aim - Minimise the Maximum time for response

MEANS OF TRANSPORT : HAA
