DeterminingifYou Have aConfined orUnconfined Space
Usethisworksheettodetermineif you have aconfinedor unconfinedspace.
Space: Includesthe roominwhichyouwillinstallheaterplus anyadjoiningroomswithdoorlesspassageways

1. Determine thevolumeof thespace(length×width×height).
Length×Width×Height= cu.ft.(volumeofspace)
Example: Space size 20ft. (length) ×16ft. ( width) ×8ft. (ceilingheight) =2560cu. ft.(volumeofspace)
If additionalventilationtoadjoiningroomissupplied withgrillsor openings,addthevolumeofthese
