TOTOXrCJTXt-AND SAFE HANDLING INFORMATION
ThV iicut^orar foxicjty krf ^rodor 1242 shows it to have an LDS0 to rats of 4.15 ml./kilogram. Presumably 'ihe"6thet:tw6Vlforfdjr:ponipouBds are in the same toxicity range. Repeated or prolonged skin contact with
these cdmpounds is top-be avoided. Inasmuch as their processing in this use does not require the use of elevated temperatures! -'there-shauld.ber.no-hazard from vapor exposure.
