Fire Hazard
This chemical is combustible.
First aid
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a oneway valve or other proper respiratory medical device.
Administer oxygen if breathing is difficult. Remove and
isolate contaminated clothing and shoes. In case of contact
with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep
victim warm and quiet. Effects of exposure (inhalation,
ingestion, or skin contact) to substance may be delayed.
Ensure that medical personnel are aware of the material
(s) involved and take precautions to protect themselves.

storage
Color Code—Blue: Health Hazard/Poison: Store ina secure poison location. Prior to working with this chemicalyou should be trained on its proper handling and storage.4,40-Methylenebis(N,N-dimethyl)benzenamine must be storedto avoid contact with oxidizers (such as perchlorates, peroxides, permanganates, chlorates, and nitrates) and strong acids(such as hydrochloric, sulfuric, and nitric), since violent reactions occur. Store in tightly closed containers in a cool, wellventilated area. A regulated, marked area should be established where this chemical is handled, used, or stored in compliance with OSHA Standard 1910.1045.
Purification Methods
Crystallise the base from EtOH (2mL/g) or 95% EtOH (ca 12mL/g). It sublimes on heating. [Beilstein 13 IV 390.]
