Health and Safety Factors. Dimethyl malonate and diethyl malonate do not present any specific danger of health ha2ard if handled with the usual precautions. Nevertheless, inhalation and skin contact should be avoided. Dimethyl malonate has a LD q (oral, rats) of 4520 mg/kg and is classified as nonirritant (skin irritation, rabbits). Diethyl malonate has an LD q (oral, rats) greater than 5000 mg/kg and is also classified as nonirritant (skin irritation, rabbits). Transport classification for both esters is RID/ADR 3, IMDH-Code, lATA-ICAO not restricted. 

Health and Safety Factors. Handling of cyanoacetic acid and cyanoacetates do not present any specific danger or health hazard if handled with the usual precautions. Cyanoacetic acid is classified as a moderate irritant (skin irritation, rabbits) and has an LD q (oral, rats) of 1500 mg/kg. Methyl and ethyl cyanoacetate are both classified as slight irritants (skin irritation, rabbits) and have an LD q (oral, rats) of 3062 and 2820 mg/kg, respectively. Transport classification cyanoacetic acid RID/ADR 8 IMDG-Code 8 lATA/ICAO 6.1. Methyl and ethyl cyanoacetate RID/ADR 6.1 IMDG-Code 6.1 lATA/ICAO 6.1. 

Health and Safety Factors. Malononitrile is usually available as a soHdifted melt in plastic-Hned dmms. Remelting has to be done carefully because spontaneous decomposition can occur at elevated temperatures, particularly above 100°C, in the presence of impurities such as alkaHes, ammonium, and 2inc salts. Melting should be carried out by means of a water bath and only shordy before use. Occupational exposure to malononitrile mainly occurs by inhalation of vapors and absorption through the skin. Malononitrile has a recommended workplace exposure limit of 8 mg/m, an LD q (oral, rats) of 13.9 mg/kg, and is classified as slight irritant (skin irritation, rabbits). Transport classification RID/ADR 61, IMDG-Code 6.1, lATA/ICAO 6.1.
