3,3′-Dimethyl-4,4′-diaminodicyclohexylmethane (MACM)Physico-chemical Properties

• Personal Precautions, Protective Equipment, and Emergency Procedures: It is recommended that emergency responders wear protective masks and fire - fighting work clothes. Do not directly contact the leaked substances. Environmental Precautions: Isolate the leakage - contaminated area and restrict access.
• Methods and Materials for Containment and Clean - up: For small spills, collect with a clean shovel into a dry, clean, and covered container. For large spills, cover with plastic sheeting and canvas, and then collect, recycle, or transport to a waste disposal site for disposal.

• Precautions for Safe Handling: Operate in a closed system and with local ventilation. Operators must receive special training and strictly follow the operating procedures. It is recommended that operators wear protective masks, chemical safety goggles, anti -poison permeable work clothes, and latex gloves. Handle with care during transportation to prevent damage to the packaging. Equip with leakage emergency treatment equipment. Empty containers may still contain harmful substances.
• Conditions for Safe Storage, including Incompatibilities: Store in a cool, dry, and well ventilated warehouse. Keep away from fire and heat sources. Prevent direct sunlight. The packaging must be sealed and protected from moisture. Store separately from oxidants, flammable (combustible) materials, etc., and avoid mixed storage. The storage area should be equipped with appropriate materials to contain spills.
