Translucent liquid with a variable amount of suspended dark precipitate.
HEALTH HAZARD DATA
The active ingredient in RDO is hydrochloric acid. It is a corrosive and a strong irritant. The vapour may also be corrosive and irritating. Skin sensitisation cam occur. A splash to the eye will cause burning. Inhalation may cause coughing and choking with possible ulceration of the respiratory tract. Ingestion will cause burning and diarrhoea. Wash thoroughly after fixation before treating with decalcifier. Hydrogen chloride and formaldehyde produce a carcinogenic compound, bischloromethyl ether.
Skin - Immediately wash the affected area with soap or mild detergent and large amounts of water until all evidence of the chemical has been removed (approximately 15 minutes). If irritation persists or dermatitis develops seek medical advice. Remove contaminated clothing and shoes and decontaminate before re-use.
Eyes - Immediately wash the affected eye with large amounts of water until all evidence of the chemical has been removed (approximately 15 minutes). If irritation or pain persists seek immediate medical attention.
Inhalation - Remove from the area of exposure to fresh air. Keep warm and allow to rest. Seek immediate medical advice.
Ingestion - Never give anything by mouth if the victim is losing consciousness, is unconscious or convulsing. Rinse the mouth thoroughly with water. DO NOT induce vomiting. Give milk to drink or egg whites. Seek immediate medical attention.
Incompatible with oxidising agents. Heating produces toxic fumes of hydrogen chloride. Hydrogen chloride and formaldehyde produce a carcinogenic compound, bischloromethyl ether.
Store in a cool, dry atmosphere away from heat and incompatible substances.
Wear protective clothing. A long sleeved laboratory coat or gown with elasticised wrist bands, rubber gloves and safety goggles as a minimum standard.
Waste material may be disposed of to sewer with large quantities of water.
This is a biodegradable product and should not cause any environmental problem.
