IS FOAM PRESENT IN YOUR FINISHING BARN MANURE PIT?
Before soaking/power washing your barn, removing the manure or
completing repair activities using welders and/or grinders please perform
these precautionary measures.
Any of the above activities will break-up foam and release explosive levels of
methane.
Don’t begin any of the above activities until the following two steps have
been completed…
1. Ventilate the barn (see *Ventilation Strategies below for both solid wall and
curtain sided barns)
2. Turn all ignition sources OFF (i.e. pilot lights, any repair work, smoking)
Only personnel doing the activity (power washing or repair work) should be
inside the barn. If the manure pit is being pumped than absolutely NOBODY
should be inside the building.
*Ventilation Strategies - 1000/1200-hd Finisher Rooms
Provide at least 30 cfm/pig (two-48" wall fans OR
three-36" wall fans OR six-24" wall/pit fans) of
ventilation for solid wall barns & curtain sided barns
(curtain closed) when winds under 10 mph.
OR
Curtains open if cross winds greater than 10 mph
But NOT
Curtains Open, Calm (under 10 mph wind) Conditions
