SECTION 2: Hazards identification
Optimus surface retarders are aqueous emulsions containing film-formers and materials to retard the set of concrete. They boil above 212 F and have no flash point below that temperature; dried film will not burn easily. Spraying the retarder can produce mist which is irritating if inhaled. Part of the retarder system includes organic acids which will cause irritation upon eye contact. Prolonged skin contact may cause skin irritation. Inhalation of the mist may cause nasal irritation. Ingestion of more than a spoonful may result in stomach upset. The preservative has been recognized as a possible sensitizer, so avoid unnecessary skin contact. They do not contain known carcinogens. …………………………………………………………………………………………………………………….
