First Aid Measures
Ingestion
Seek medical attention. If individual is drowsy or unconscious, do not give anything by mouth; place individual on the left side with the head down. Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended.

Hazards Identification
Skin
Erythema and bizarre pigmentation have been seen. Superficial and deep second-degree burns to the skin have been reported following puva therapy. At therapeutic doses, 8-mop will cause more dermal reactions than 5-mop.

Fire Fighting Measures
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.
