Partition walls and hydrated lime

[wolf63]

A friend who has no computer access has asked me to find out about the link between partition walls where hydrated lime is used as a fire retardant and health problems.

Do all partition walls have this or is it an old method?

Any information will help me before I go off on my search for information.

Thanks.

Lime is was the traditional way of building houses. It was used as the filler in bricks before mortar, and as a covering on the inside and outside walls. Today it is sometimes used as an additive to mortar or gypsum plasters.
There are issues when applying it because of the dust. I don't know about it being used specifically as a fire redardant. The following might help.
