Saving lives not levies on old balcony balustrades

I wonder what owners corporation responsibility is when they are part of lot property? We have lovely old style iron balustrades which are lot property and probably not safe, but can be made safe (I have netting on mine to keep my cats safe and keep out pigeons, and a drunk person would also bounce off  and not go over the edge). You could add glass panels which would look better. An OC could still promote and encourage making railings safe.
