Once the lineup cards are submitted (approx. 5 minutes before game time), the umpires take control of the field and the crew chief becomes the person who decides whether to delay or postpone a game (and if/when to restart).
A firewood moisture meter can be used to determine the moisture content of your firewood, but are they a necessity or just a novelty? Seasoned firewood is considered to have a moisture content of 20% or less.
Calculated values. 1  Relative humidity - average relative humidity of the air surrounding the sample of wood over the last week or so. 2  Equilibrium moisture content (EMC) - the moisture content of a wood sample when the sample is in equilibrium with the surrounding air (it is neither drying nor wetting). Wood will eventually reach equilibrium if it remains in air where the temperature and relative humidity are constant.
