The approach towards
the from Vantilating
equipment appears to have improved
the
Kanagement's sido but unfortunately the underground employees
* with few exceptions will not use the equipment unless forced
.
to do so Huch of this faultfault lies with the underground
supervisors who seam loathe to force the mon to use the appliances
na required by Regulation 152 of the Wines Regulation Act Of
all the places visited onlyonly a few bad the ventilation equipment
correctly installedinstalledinstalled and in use Before we left each place the
the person concerned was made to bringbring
ventilation up to standard
and in some instances a warningwarning given It appears the only
,
a stranger line of action against both employees
and supervisors If the supervisors were to continually force
the men to do the right thing then much of the present trouble
be would eased

doubtful

a definite improvement in conditions should be possible . .
