HEALTH HAZARD DATA
Phloxine is highly toxic via the intravenous route. Other data has not been quantified although because of its chemical structure it is assumed to be an eye and skin irritant. It causes foetal death in animals.
TREATMENTS
Skin ­ remove contaminated clothing then wash the affected area with soap or mild detergent and large amounts of water until all evidence of the dye has been removed (approximately 15 minutes). If irritation persists seek medical advice. Wash contaminated clothing before re­use.
