The process of carbonising in the production of shoddy may give rise to injury to health from acid fumes. Lead poisoning used to be caused by the knocking together of the leaden weights attached to the Jacquard looms. This is a thing of the past, as now iron weights are universal.
Opportunity for lead poisoning is given in the weighting of yarn—especially of silk with lead compounds.
In bleaching use of chlorine and sulphur dioxide has to be borne in mind.
In chemical cleaning poisoning by benzine may occur.
In dyeing and printing use of poisonous colours is lessening, as they have been supplanted by aniline colours. On occurrence of aniline poisoning in aniline black dyeing see the section on Aniline. Use of lead colours and of chromate of lead are dealt with in special sections.
PART II
THE SYMPTOMS AND TREATMENT OF INDUSTRIAL POISONING
In this section the most important diseases and symptoms of industrial poisoning will be described. In doing this—considering the mainly practical purpose of this book—theoretical toxicological details and any full discussion of disputed scientific points will be omitted.
