Properties and essential information for the safe handling and use of paraformalde hyde are described in a new chemical safety data sheet published by the Manufacturing Chem ists' Association, Paraformaldehyde is a mixture of polyoxymethylene glycols containing 90 to 99% polymerized formaldehyde. It varies in degree of polymerization, and is available commercially in both powder and granular form as follows: 91 to 92% Flake; 94 to 95% Powdi 95 to 99% U.S.P.X. and Photographic. The toxicity of paraformaldehyde is similar to that of formaldehyde. In some ways it is less hazardous since it is less reactive. It is toxic by oral intake. The vapors are irritating to the eyes and upper respiratory tract. Although a threshold limit value of 5 ppm by volume in air has been set by some agencies as the safe con centration for an 8-hour exposure, this concentration may prove uncomfortable for some 03120733 1. .
