DISPOSAL METHODS THAT MAY BE USED IN THE FIELD:
NOTE: Local, state, federal, and host-nation regulations or laws may prohibit burning or burial of waste. The garbage, rubbish, and other such material may have to be transported to a waste disposal facility. Chemical toilets are the required human waste disposal devices for use during field exercises or missions. Improvised devices may be used under emergency conditions; the burn-out latrine is the preferred method for improvised devices.
Collect and transport to approved disposal facilities.
Burial-Less than 1 week.
Incineration-Longer than a week.
Liquid kitchen or bathing waste disposal.
Human waste disposal.
Chemical toilets. Urinals should be provided in these facilities to prevent soiling the toilet seats, if possible.
Individual waste collection bags on the march or for small groups in isolated areas.
Cat-hole latrine for marches if individual waste collection bags are not available.
Field expedients when individual waste collection bags are not available
Pail latrine when chemical toilets are not available, the ground is too hard, or the water table is too high (soil is very wet).
Straddle trench for 1 to 3 day bivouac sites when burn-out or pail latrine are not available.
Deep pit latrine for temporary camps.
Soakage pits for urinals at temporary camps.
Urinoil. (See page A-44 for further information on the urinoil.)
STEPS OF PERFORMANCE:
STEP 1: Use the following chart to determine disposal requirements.
STEP 2: Select site of construction.
Garbage and soakage pits should be at least 30 meters from food service.
Latrine should be as far as possible from food service (100 meters or more is best).
Latrine should be located on level ground. Never uphill from the campsite or water supplies.
STEP 3: Construct disposal facility.
Garbage pit-Used to prevent accumulation of garbage in the unit area.
NOTE: Garbage and rubbish should be transported to an approved landfill or must be buried or burned. If buried for short stays, cover daily. For longer periods, garbage and rubbish may have to be burned; however, the ashes should be buried. (Reader should consult the note on page A-32.)
Soakage pit/trench-Used to prevent accumulation of liquid waste (water from showers, sinks, and field kitchens).
Grease trap-Used with both soakage pit and trench to prevent clogging of soil.
Cat-hole latrine-Used only on the march (if individual waste collection bags are not available) and covered immediately after use.
Chemical toilets-Used as the standard field latrine.
Straddle trench latrine-Used on short bivouacs and field training exercises.
Two trenches per 100 males and three trenches per 100 females.
Deep pit latrine-Used for longer periods of time and in built-up areas. Collapsible two-seat boxes are available in the supply system.
NOTE: If ground is too hard for digging, or if the water table is too high, use a pail latrine or a burn-out latrine.
Pail latrine-Use where water table is too close to the surface of the ground for digging a deep pit latrine.
Burn-out latrine-Use where water table is too close to the surface of the ground for digging a pit latrine, or stay is for an extended period.
Urinals-For male latrines, construct one of the following urinals: trough urinal, pipe urinal, or urinoil.
STEP 4: Inspect daily to make sure that the following is done:
Waste is collected and transported to an approved disposal facility.
Straddle trench latrines and garbage pits are covered with dirt daily.
Pail latrines are emptied and cleaned daily.
Burn-out latrine containers are rotated and contents burned daily. · Facilities (not the contents) are sprayed with insecticide for fly control when other control techniques fail.
STEP 5: Close improvised latrines and garbage pits when filled to within 1 foot of the ground surface. Have chemical toilet contents removed daily.
Close out by-
Spraying with residual insecticide.
Packing earth in successive 3-inch layers until mounded 1 foot above ground level. Spraying again with residual insecticide.
Posting a sign stating, Closed latrine/garbage pit and date (except in combat).
TASK 10: Construct and maintain field hand washing and shower devices.
EQUIPMENT NEEDED: Personnel detailed to construct and maintain field hand washing and shower devices. Material as required for type of facilities to be constructed.
STEPS OF PERFORMANCE:
STEP 1: Select device to be constructed.
Hand washing devices.
STEP 2: Construct devices.
Collocate hand washing devices at food service and latrine locations.
NOTE: A soakage pit should be provided for all hand washing and shower facilities.
STEP 3: Maintain devices. A supply of soap and water must be available at all times.
STEP 4: Close devices.
