  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Risk of explosion as a result of decomposition when heated.      In case of fire in the surroundings, use appropriate extinguishing media.   

 AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS PREVENTION FIRST AID
Inhalation Blue lips, fingernails and skin. Headache. Dizziness. Nausea. Confusion. Convulsions. Unconsciousness.  Use ventilation (not if powder). Use local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin MAY BE ABSORBED! Redness. Pain. Further see Inhalation.  Protective gloves.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain.  Wear safety goggles or eye protection in combination with breathing protection if powder.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion See Inhalation.  Do not eat, drink, or smoke during work.  Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered non-metallic containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

HYDROXYLAMINE HYDROCHLORIDE ICSC: 0709
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS HYGROSCOPIC CRYSTALS. 

Physical dangers
No data. 

Chemical dangers
Decomposes slowly on contact with moisture. Upon heating, toxic fumes are formed. Decomposes on heating. This generates explosion hazard. The solution in water is a weak acid. Attacks many metals. 

Formula: NH2OH.HCl
Molecular mass: 69.5
Melting point: 154°C
Decomposes: see Notes.
Density: 1.7 g/cm³
Solubility in water, g/100ml at 25°C: 94 (freely soluble) 


EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the blood. This may result in the formation of methaemoglobin. Medical observation is indicated. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the blood. This may result in the formation of methaemoglobin. Tumours have been detected in experimental animals but may not be relevant to humans. 


OCCUPATIONAL EXPOSURE LIMITS
MAK: sensitization of skin (SH) 

ENVIRONMENT
The substance is very toxic to aquatic organisms. 

NOTES
Do NOT take working clothes home.
Decomposition of compound starts at 154°C.
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.
See ICSCs 0661 and 1747.
