Contact with excessive amounts of polymeric MDI can be harmful to your health. When MDI is sprayed, you may be overexposed by:
Inhalation
If MDI is inhaled, it can cause irritation to the nose and lungs. If inhaled over a period of time, a person may feel tightness in the chest and have difficulty breathing. Continued over exposure may cause the body to become sensitized (or allergic) to MDI, which means even very low levels of MDI can cause serious health effects, including asthma attacks. Immediate medical attention is needed if this occurs.
Skin or Eye Contact
MDI should not come in direct contact the skin or the eyes. Repeated contact with the skin may cause discoloration, redness, swelling or blistering, which could lead to skin sensitization. If MDI comes in contact with the skin, wash the area thoroughly with soap and flowing water, and seek immediate medical attention.
Getting MDI in the eyes can be painful and could cause tearing and irritation. If this occurs, immediately wash out the eyes with a continuous flow of low pressure water for at least 15 minutes. Seek immediate medical attention.
Swallowing MDI
If MDI is swallowed, vomiting should not be induced. Instead, the mouth should be washed out with water, and the person affected should rest and seek immediate medical attention.
Setting up a spill clean-up plan may help you quickly clean up product if a spill or leak occurs. Protecting people first, then minimizing environmental releases and protecting property will help prevent people from being exposed to potentially harmful levels of MDI. Of course, any spill should be addressed in compliance with U.S. environmental laws and in accordance with the manufacturers MSDS.
