Which statement is correct about burn-out latrines?

• A. Remaining ash must be buried
• B. Uses 55-gallon drum: whole or in half
• C. Must stir contents continuously
• D. 4 parts diesel to 1 part gasoline

Answer: (A)

Burn-out latrines rely on burning the latrine contents to reduce volume and destroy pathogens, after which the remaining ash must be buried. Burying the ash seals it off, minimizes exposure to people and animals, and helps prevent contamination of soil and groundwater as the pit is closed and prepared for the next cycle or reuse. The other statements describe equipment or practices not standard or recommended in this method: a 55-gallon drum isn’t a universal requirement, continuous stirring isn’t part of the procedure, and mixing diesel with gasoline is unsafe and not used in burn-out latrines.
