Medical Management

FIRST AID FOLLOWING OVEREXPOSURE

Remove individuals affected by overexposure to diisocyanates from the source of exposure. Remove contaminated clothing and place in a plastic bag for decontamination or safe destruction later. Administer first aid immediately.

• For breathing difficulties: Obtain medical attention immediately, but inform affected individual and medical personnel that onset of symptoms may occur several hours after exposure.
• Eye Contamination: Flush eyes using an eye wash station, several sterile eye wash bottles or copious amounts of tap water. Remove contact lenses if easily removable and continue eye irrigation for up to 15 minutes. Obtain medical attention.
• Skin Contamination: Wash immediately with soap and water. Cured material is difficult to remove; however, practical experience has demonstrated that some of the best ways to remove it is with corn oil, petroleum jelly or industrial skin cleanser (e.g., D-TAMTM Safe Solvent: Colorimetric Laboratories, Inc.).
• Swallowing: Do not induce vomiting. Wash mouth well with water. Obtain medical attention.

NOTE FOR GUIDANCE TO MEDICAL PERSONNEL

Diisocyanates are respiratory and skin irritants and potential sensitizers. There is no specific antidote. Treatment should be essentially symptomatic for irritation of skin and mucous membranes and/or bronchospasm. MDI and TDI have very low oral toxicity. Post incident follow-up is needed. For more specific information see relevant (M)SDSs.
