About This Book

The authors survey lead’s chemistry, historical uses, and the routes and mechanisms of absorption, emphasizing inhalation of dust in industrial settings. They examine susceptibility, statistical occurrence, pathological changes, nervous system effects, methods for detecting and measuring lead, excretion, clinical symptoms, and treatment. Detailed experimental findings are presented to clarify causation and inform prevention, and practical recommendations focus on engineering controls such as local exhaust ventilation and workplace hygiene. Descriptions of hazardous processes and discussion of regulatory and technical measures aim to translate clinical and laboratory knowledge into strategies for reducing occupational lead risk.

[A] It is not available for velocities exceeding 1,200 linear feet per minute.

The details of all routine observations on localized exhaust ventilation might well be entered on a card hung up in the workroom. Such a card drawn up by our colleagues, Miss Lovibond and Mr. C. R. Pendock, has the following headings:

Frequent cleaning and inspection of exhaust installations are very important, as accumulation of dust greatly impedes the flow of air at all points of the system. The person employed in cleaning the fan should wear a respirator. Hoods and ducts should always be cleaned with the exhaust in full action.
