Caution - Inorganic metal cleaners can be dangerous.
This profusely illustrated booklet, intended as a handy information sheet for workers, deals with the following points: uses of inorganic acids and caustics in metalworking; chemical burn hazards and other health hazards (causes and symptoms); preventive measures (handling, dispensing, mixtures, storage; dangerous chemical reactions; correct ways to clean up spills; local exhaust ventilation; protective clothing and respirators); first aid.

Criteria for a recommended standard: Occupational exposure to sodium hydroxide.
Recommendations are made for the prevention of occupational injuries and diseases due to exposure to sodium hydroxide. The maximum exposure concentration is 2.0mg/m3 air for any 15min-sampling period. Other recommendations relate to medical supervision, labelling, personal protection, information of employees, work practices, monitoring and record keeping. The criteria on which the recommendations are based are discussed at some length under the headings: biological effects of exposure, environmental data, development of a standard. Procedures for sampling and analysis of sodium hydroxide in air are described in detail and useful additional information is given in appendices.

Examination of cutaneous tolerance to strong and weak acids and bases at various pH values
Essai de tolérance cutanée à l'action d'acides et de bases fortes et faibles à des pH variables. [in French]
M.D. thesis. The results are reported of cutaneous tolerance tests on guinea pigs, in order to study, among irritants, those that are corrosive to skin on account of their acidity or basicity. The experiments with histological tests were made with sulfuric, hydrochloric, nitric and acetic acids and with sodium, potassium and ammonium hydroxides. The results do not confirm the hypothesis that acids of low pH are not harmful to the skin. For bases, below pH9, the harmlessness is confirmed. All cutaneous lesions due to industrial products whose pH is equal to or less than 4, or equal to or greater than 12 should be considered as compensatable as occupational injuries.

Aggressiveness of javel water and peracetic acid - Study on the rabbit skin and eye in various concentrations
Agressivité de l'eau de Javel et de l'acide peracétique - Etude sur la peau et l'¿il du lapin à différentes concentrations. [in French]
This experimental study is the first of a series devoted to the aggressive action on the skin and ocular mucosae of certain common industrial products reputed to be caustic. The results and observations are tabulated: chemical composition of the substances studied, gross and microscopic examination of lesions induced on the rabbit eye and skin (without or after washing of the affected parts), course of the lesions, etc. The study is illustrated by 3 colour plates.

Factors in the evaluation of alkali-resistance tests
Einige Aspekte bei der Auswertung der Alkaliresistenzprobe [in German]
A study of the relationship between alkali resistance and various forms of dermatitis, time-related changes in alkali resistance, the relationship between alkali resistance and profession, and of practical applications of the alkali resistance test. The most frequent reduction of alkali resistance was encountered in nurses, female laboratory assistants, farmers, gardeners and housewives. On the basis of these results the practical value of the alkali-resistance test seems doubtful.

The influence of skin-surface lipids on Burckhardt alkali-resistance testing
Einfluss der Hautoberflächenlipide auf das Ergebnis der Alkaliresistenz-Bestimmung nach Burckhardt [in German]
Burckhardt alkali resistance tests were made on 130 persons and the quantity and composition of skin-surface lipids were determined. It was found that, under physiological conditions, neither lipid quantity nor composition have any significant effect on alkali resistance.
