Study Notes

NAVMED P-5010 Chapter 9 Overview

Chapter 9 focuses on sanitation practices, including water purification and waste management, vital for ground forces.

Water Purification Equipment

Reverse Osmosis Water Purification Unit (ROWPU): Most commonly used field purification system.
ERDLATOR: A portable system for aerating, filtering, and disinfecting contaminated water.

Water Disinfection Methods

Chlorination is the primary method for disinfecting potable water.
Calcium Hypochlorite (HTH): Preferred chlorine agent due to granular form, long shelf life, and availability.

Water Treatment Procedures

Iodine tablets: 2 tablets are added to each canteen of water; 40 tablets for a 5-gallon container.

Food Safety and Storage

Food Service Officer is responsible for inspecting food items upon receipt.
Field refrigerators must be kept below 40°F; freezers below 0°F.
Thawed foods must never be refrozen.

Waste Management and Latrine Construction

Cat holes: Dimensions are 8 to 12 inches in diameter and 6 to 12 inches deep, used when troops are on the march.
Straddle Trench: Measures 1 foot wide, 2.5 feet deep, and 4 feet long; serves up to 25 people.
Deep Pit Latrine: Built over an 8-foot-long, 2.5-foot-wide pit; accommodates up to 50 people.
Bored Hole Latrine: Consists of an 18-inch hole bored to 15-20 feet deep; 8 are needed for every 100 people.

Urine Disposal Systems

Urine soakage pit: 4 feet deep with 6 tubes inserted, each accommodating 20 people.
Urinoils: A 55-gallon drum that traps urine and disposes of it through a soakage pit.

Garbage Disposal Methods

Two ways to dispose of garbage: Burial and incineration.
Garbage refers to solid or semisolid waste from food preparation and serving; rubbish is dry, disposable waste.

Heat Cramps: Severe muscle cramps primarily in extremities; arises from loss of salt and water.
Heat Syncope: Occurs due to blood pooling in extremities, reducing blood flow to the brain.
Heat Exhaustion: Results from excessive water and salt depletion causing vascular collapse.
Heatstroke: Severe condition from the failure of thermal regulatory mechanisms.

Heat Stress Assessment

Wet Bulb Globe Thermometer (WBGT): A key tool for monitoring heat stress on the body.
WBGT color code: Green flag at 80-84.9, Yellow at 85-87.9, Red at 88-89.9, Black above 90.

Cold Weather Injuries

Cold Injury: Tissue damage from cold exposure.
Immersion Syndrome: Occurs in cold water (below 50°F) after 24 hours.
Frostbite: Results from exposure to low ambient or windchill temperatures.
Hypothermia: General cooling of the body's core temperature.

Communicable Diseases

Defined as diseases transmitted from a carrier to a susceptible host.
Chain of transmission includes: Reservoir, Means of Transmission, Portal of Entry, and Susceptible Host.

Specific Disease Infestations

Zoonotic Diseases: Transmitted from animals to humans, can be direct (rabies) or vector-borne (plague).
Pediculosis: Infestation of lice.
Scabies: Infectious skin disease caused by mites, visible as skin burrows.
