When you are using Disperse Yellow 3, please be cautious about it as the following: 1-Methylamino-4-ethanolamino-anthraquinone may cause eye and skin irritation. In case of contact with eyes or skin, flush eyes or skin with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. Besides, it may cause respiratory tract irritation and may be harmful if inhaled. If inhalation, remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. Store in a cool, dry place. Store in a tightly closed container. As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. And Use water spray, dry chemical, carbon dioxide, or chemical foam to put out fire.
