BIS(HYDROXYLAMINE) SULFATE ICSC: 0898
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS OR POWDER.

CHEMICAL DANGERS:
On contact with hot surfaces or flames this substance decomposes forming corrosive fumes of sulfur oxides. The solution in water is a medium strong acid. The substance is a strong reducing agent and reacts violently with oxidants powdered metals, nitrates, nitrites and heavy metal salts.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

INHALATION RISK:
A harmful concentration of airborne particles can be reached quickly when dispersed.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the skin. The substance may cause effects on the blood, resulting in the formation of methaemoglobin.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the blood, resulting in anaemia.

Melting point (decomposes): 120C
Density: 1.88 g/cm^3
Solubility in water, g/100 ml at 20C: 58.7
Octanol/water partition coefficient as log Pow: -3.6
ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms.
NOTES
Depending on the degree of exposure, periodic medical examination is suggested. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
