The Great War (World War I)
5
The Influenza Pandemic of 1918
The influenza pandemic of killed more people than the Great War, known today as World War I (WWI), at somewhere between 20 and 40 million people. It has been cited as the most devastating epidemic in recorded world history. More people died of influenza in a single year than in four-years of the Black Death Bubonic Plague from 1347 to Known as "Spanish Flu" or "La Grippe" the influenza of was a global disaster

10
Debilitating and Non-Battle Injury (DNBI)
DNBI accounts for more than 50% of casualties Direct reflection on the lack of PMM Lack of PMM causes breakdown in soldier’s health and capability to function
11
Medical Threat to Field Forces
Casualties caused by DNBI have had a serious impact on military operations since the dawn of recorded history The four major contributors to DNBI are: Heat Transmitted diseases Cold Diarrheal diseases
12
Importance of Field Sanitation
The success or failure of the unit and its mission may be jeopardized because of the lack of proper preventive medicine measures To help reduce disease and health problems, soldiers at every level must be educated on Field Sanitation
13
Importance of the Field Sanitation Team (FST)
FST members should instruct/guide soldiers on the hazards of neglected personal hygiene The FST must have basic sanitation and protection roles
14
Role of the FST Supervise: Disinfecting of water
Construction of garbage areas Construction of soakage pits Construction and cleaning of field latrines
15
Role of the FST Provide training and guidance to food service
personnel on the prevention and elimination of deficiencies in food service sanitation Report any deficiencies to the commander for necessary action
16
Preventive Medicine Measures
Personal Hygiene and Preventive Medicine Measures
17
Promote Personal Hygiene by
arranging for hand-washing and showering facilities providing hot water for showering and shaving providing heated dressing rooms providing sanitary controls preventing water collecting and pooling
18
Hygiene Devices Hand-wash devices at each latrine
Hand-wash for soldiers at eating locations Hand-wash for cooks at the field kitchen Soakage pits Soap and towels
19
Good Personal Hygiene Prevents
Foot problems Skin rashes Body lice Hair lice Diarrhea and gastrointestinal problems Depression and social instability
20
Good Personal Hygiene Promotes
Healthier soldiers Self-satisfaction among troops Better work performance Less sick calls More soldiers on the front line
21
Water Supply in the Field
22
In combat, safe water ranks in
importance with ammunition and food. It often has an important bearing on the success or the failure of a mission.
23
Importance of Good Water
Soldiers must be supplied with sufficient amounts of water Water must be safe to drink and cook with Water should be safe and clear of objectionable tastes, odors, turbidity, and color Water is a vehicle for transmission of disease organisms
24
Testing the Water Water should be tested for the presence of Coliform bacteria Coliform bacterii are found in great numbers in the excreta (feces) of humans Hepatitis, leptospirosis, typhoid, cholera, diarrhea may be present in feces
25
Production of Safe Water
Check the bacterial content Check the chlorine residual content Establish standards for water quality Inspect water points After testing and treating, approve water for consumption and use
26
Water Supply and Treatment
The unit commander makes certain that: There is an adequate supply of good water The rules of water discipline are enforced Everyone understands the hazards of drinking unsafe water The water supply will be protected by good sanitary practices
27
Terms and Definitions Palatable - agreeable taste
Potable - safe to drink Treatment - procedure to change the chemical composition Chlorinating - increases the residual level to a safe minimum PPM - parts per million
28
Disinfecting the Lyster Bag
Dissolve calcium hypochlorite ampules in a canteen cup Add to water, stir Flush faucets Wait ten minutes Test water for proper residual levels Let water stand for 20 minutes before use
29
Treating the 400 Gallon Water Trailer
Mix 3 MRE spoonfuls of calcium hypochlorite with 1/2 cup of water Add to water, stir Flush faucets Wait ten minutes, test again If residuals are at 5 PPM, wait 20 minutes before use
30
Treating the Canteen Use two iodine tablets in each full canteen of water Place tablets in canteen, wait 5 minutes Shake canteen Loosen cap, allow clean water to seep around the neck to kill any organisms Minimum contact time is 30 minutes
31
Water Supplies Under all situations in the field, soldiers must be supplied with sufficient amounts of potable water. This requires a coordinated effort between the State medical authority, the commander, and the field sanitation team.
32
Waste Disposal in the Field
Proper waste disposal is essential in preventing the spread of disease. Solid and liquid wastes produced under field conditions can be as much as 100 lbs per person per day. The unit commander and First Sergeant are responsible for the removal of trash and garbage, not Food Services.
33
Human Waste Disposal Huge problem for the unit and soldiers in the field Chemical Latrines should be provided for 4% of the male population and for 6% of the female population Located 100 yards downhill from water sources and field kitchens Hand-wash devices should be provided at each latrine
34
Garbage Disposal Most Training Sites do not allow burying garbage
garbage must be separated must be hauled to landfill Liquid waste (grease and oils) 1-5 gallons per person per day is normal must be contained for proper disposal most training sites have recycle drums
35
Waste Disposal Before trash, garbage, grease, oils, or human waste is burned, buried, dug in, or covered up, check with the Installation Environmental Officer for proper procedures. It may save you at lot of headaches and money.
36
Arthropods and Disease
It is important for you to know that throughout history more soldiers have been killed or disabled from arthropod-borne disease than from actual combat.
37
Arthropods Any member of the phylum Arthropoda, which includes the insects, centipedes, crustaceans, millipedes, mites, scorpions, spiders, ticks, fleas, mosquitoes, flies, etc. In many cases, the arthropod is the vehicle or cause of the disease.
38
How Arthropods Affect Human Health
By direct injury stings or bites Through disease transmission bacteria deposited on food Myiasis larvae migrate through human host fly eggs turn into maggots in stool
39
Common Arthropods mosquitoes filth fly house fly scorpions ticks mites
fleas red bugs deer flies wasps
40
Arthropod-borne Diseases
Malaria - mosquito Yellow Fever - mosquito Dengue Fever - mosquito Encephalitis - mosquito & ticks Typhus body lice Bubonic Plague - fleas
41
Management of Arthropods through Field Sanitation and PMM
Since the ideal location of bivouac sites are not always possible, we must know how to manage arthropods which affect the health of the soldiers. Through effective measures we can control arthropod infestation.
42
Individual PMM Clothing worn loosely
trouser legs tucked in without blousing rubbers shirt sleeves rolled down and buttoned no holes or tears head gear worn (insect screen may be attached)
43
Clothing Repellent Some repellents can be applied directly to the clothing. The two methods which are acceptable are by aerosol spray or by dipping into a repellent solution. Either method must be approved by the Installation Surgeon and the directions for use must be strictly followed.
44
Skin Repellent Repellent may be applied directly to the skin, spread evenly over the area. Do not get chemicals into eyes. Skin repellent may be used on clothing. Apply a few drops or spray compound on clothing around openings.
45
PMM for rest periods Screened billets - desirable, but not always
available Bed nets - a necessity to be used in conjunction with screened billets Aerosol spray - the last line of defense, sprayed in and around billets
46
Equipment used for Control
Hand Duster - delousing application Hand Pressure Sprayer - general application - 2 gallon capacity Aerosol cans - general application for small areas Bottles - general application for uncovered skin
47
Control of Arthropods with Pesticides
A pesticide is any substance or mixture of substances or chemicals which kills pests. Pesticides are used to augment, not replace, field sanitation and individual PMM.
48
Application of Pesticides
IMPORTANT FACTORS TO BE CONSIDERED WHEN DISPENSING PESTICIDES: Toxic effect when inhaled Degree and speed of skin absorption Cumulative effect in the body Concentration of toxicant Amount of pesticide that must be applied Conditions under which chemicals are applied
49
Rodent Management Rodents are the carriers of several diseases which are harmful to humans The best known and most serious is the plague, a disease transmitted to humans by rodent fleas Rodents are known to cause millions of dollars of damage to crops
50
Types of Rodents Norway Rat found at ground level
likes to burrow in the ground found mostly in temperate regions roams feet in search of food and water likes people food life span 1 year each female can produce 84 young rats per year
51
Types of Rodents Roof Rat found in attics and walls
roams feet in search of food and water found everywhere in the world likes people food, prefers vegetables life span 1 year each female can produce 64 young rats per year
52
Types of Rodents House Mouse found in attics and walls
found everywhere in the world likes people food * 1/10 oz of food per day * 1/20 oz of water per day roams 50 feet for food and water life span 1 year each female can produce 84 young rats per year
53
Diseases Caused by Rodents
Leptospirosis acute fever jaundice and bleeding deadly infectious disease meningitis treatment is with penicillin
54
Diseases Caused by Rodents
Plague fever up to 104*F nausea and vomiting headache muscular pain mental disorientation and delirium certain DEATH within a few days
55
Looking for Rodents sightings gnaw marks
presence of dead rodents tracks droppings nests smudge marks on baseboards sounds burrows or holes odors
56
Rodent Elimination eliminate access to garbage
dispose of garbage regularly do not leave food out store all food in tightly sealed containers clean up all food spills repair all water leaks seal off all exterior openings
57
Rodent Elimination clean up building materials
thin or remove dense vegetation trim tree limbs stack materials away from walls remove paper, cardboard boxes, cloths any materials that can be used for nests
58
Elimination Devices Snap traps against walls behind objects
secure the bait checked and reset daily meats (Norway rat) dried fruits (Roof rat) peanut butter (House mouse)
59
Chemical Elimination involves the use of rodenticides
blood anti-coagulant chemicals do not use in food storage, prep, or serving areas bait stations should be placed against walls or burrows should give the rodent a secure place to feed
60
Disposal of Dead Rodents
spread insect repellent on your hands, sleeves, and the front of your clothes pick up rodent with long-handled tongs or a shovel place carcass in plastic bag and place in tightly fitted refuse container spray general purpose pesticide in refuse container
61
Chemical Hazards Occupational hazards may be classified as
chemical, physical, or biological. Chemicals may produce injury or death in all situations, including combat. The loss of key personnel has a direct effect on the unit’s ability to accomplish its mission.
62
Chemical Routes of Entry
Inhalation Absorption Ingestion Injection
63
Liquid Gas Vapor Mist Solids Dust
Chemical Classes Liquid Gas Vapor Mist Solids Dust
64
Chemicals odorless and colorless space heaters
automotive exhaust fumes non-irritating slow working interferes with oxygen to the body causes headaches, sleepiness, coma, and death
65
Chemicals Hydrogen Chloride exhaust from rocket systems
Bore/gun gasses contain lead deposits contains carbon monoxide effects respiratory system with flu-like symptoms acid burns to eyes, throat, lungs, skin
66
Chemicals Liquids solvents insecticides fuels skin irritations
lubricants chemical burns
67
Noise Hazards We are surrounded by sounds 24 hours a day. We are so used to a sound filled environment that a lack of sound can be very disturbing. But, too much sound can have profound physical effects on our hearing, and can cause deafness.
68
Types of noise Impact or impulse noise Continuous or steady noise
very loud in short bursts small arms fire, cannon fire, gun fire Continuous or steady noise field generators tank interiors personnel carriers truck cabs aircraft First Sergeants
69
Recognizing the Effects of Noise
ringing in ears temporary loss of hearing ear ache equilibrium loss headache
70
Hearing Protection armor crew helmet helicopter crew helmet
aircraft ground crew “ears” earmuffs earplugs
71
Plan for Noise identify existing noise in your unit
outfit soldiers with proper protection protectors should be cleaned regularly control noise sources instruct soldiers on proper wear instruct soldiers on effects of hearing loss
72
Summary Field sanitation and hygiene is the personal responsibility
of each and every soldier. Those measures the individual fails to follow affects not only that one soldier but each and every soldier around them. Leaders at all echelons need to rigorously enforce field sanitation and hygiene to ensure that their unit is healthy and prepared physically for the stresses of combat. Failing to adhere to these guidelines is a certain way to cause your unit to become incapable of conducting its mission.
