A G uide for the Preparation of
'Warning Lab els for Hazardous Chemicals !r< the last few years the development of new chemical compounds, the wartime
necessity of using unshilled labor, and the introduction of chemical processes into new fields of industry have emphasized the need for improved labeling ol chemical products. The Manufacturing Chemists* Association, for many years a strong force in the improvement of methods for the shipping and handling of chemicals, enlarged its activities in this field by fornnnng, about a year ago, its Label and Precautionary information Committee. This committee, composed of competent technical and legal personnel, has worked intensively during the past year and has developed certain basic principles, classification of hazards, and recommended forms for labels. This work has been compiled by the M C A in its recently issued Manual L -1 , entitled " A Guide for the Preparation of Warning Labels for Hazardous Chemicals". Because of the valuable informa
