| [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. | |
| [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. | |
| [Inhalation] If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention. | |
| [Skin] Remove contaminated clothing. Wash exposed area with soap and water. If symptoms persist, seek medical attention. Launder clothing before reuse. | |
| [Eyes] Uv absorbing wrap should be used around sunglasses for 24 hours after methoxsalen ingestions. This decreases the potential for cataract formation. | |
| [Storage] Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage. | |
| [Handling] All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood. | |
| [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. | |
| [Ingestion] Nausea and abdominal pain have occurred. | |
| [Personal Protection] Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots. | |
| [Respirators] Use NIOSH/MSHA approved respirator appropriate for exposure of concern. | |
| [Exposure Effects] dizziness, depression, and headache have been reported with use, as have nervousness and insomnia. Seizures have been reported in animal studies. | |
