% by Weight
Data on Ingredients: Hydroxylamine
hydrochloride: ORAL (LD50): Acute: 408 mg/kg [Mouse]. 141 mg/kg [Rat].
3: Hazards Identification Potential Acute Health Effects:
hazardous in case of skin contact (irritant), of eye contact (irritant), of
ingestion, of inhalation. Slightly hazardous in case of skin contact (corrosive,
sensitizer), of eye contact (corrosive). The amount of tissue damage depends on
length of contact. Eye contact can result in corneal damage or blindness. Skin
contact can produce inflammation and blistering. Inhalation of dust will produce
irritation to gastro-intestinal or respiratory tract, characterized by burning,
sneezing and coughing. Severe over-exposure can produce lung damage, choking,
unconsciousness or death. Inflammation of the eye is characterized by
watering, and itching. Skin inflammation is characterized by itching, scaling,
reddening, or, occasionally, blistering.
Chronic Health Effects:
hazardous in case of skin contact (sensitizer). CARCINOGENIC EFFECTS: Not
available. MUTAGENIC EFFECTS: Mutagenic for mammalian somatic cells. Mutagenic
for bacteria and/or yeast. TERATOGENIC EFFECTS: Not available. DEVELOPMENTAL
TOXICITY: Not available. The substance may be toxic to blood, cardiovascular
system, upper respiratory tract, skin, eyes. Repeated or prolonged exposure to
the substance can produce target organs damage. Repeated exposure
the eyes to a low level of dust can produce eye irritation. Repeated skin
exposure can produce local skin destruction, or dermatitis. Repeated inhalation
of dust can produce varying degree of respiratory irritation or lung damage.
Repeated exposure to a highly toxic material may produce general deterioration
of health by an accumulation in one or many human organs.
4: First Aid Measures Eye Contact:
for and remove any contact lenses. In case of contact, immediately flush eyes
with plenty of water for at least 15 minutes. Cold water may be used. Get
medical attention immediately.
case of contact, immediately flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Cover the irritated skin

container dry. Keep away from heat. Keep away from sources of ignition. Empty
containers pose a fire risk, evaporate the residue under a fume hood. Ground all
equipment containing material. Do not ingest. Do not breathe dust. Never add
water to this product. In case of insufficient ventilation, wear suitable
respiratory equipment. If ingested, seek medical advice immediately and show the
container or the label. Avoid contact with skin and eyes. Keep away from
incompatibles such as oxidizing agents, combustible materials, organic
materials, alkalis. Storage: Keep container tightly closed. Keep
container in a cool, well-ventilated area. Hygroscopic Moisture sensitive.
8: Exposure Controls/Personal Protection Engineering Controls:
process enclosures, local exhaust ventilation, or other engineering controls to
keep airborne levels below recommended exposure limits. If user operations
generate dust, fume or mist, use ventilation to keep exposure to airborne
contaminants below the exposure limit.
goggles. Synthetic apron. Vapor and dust respirator. Be sure to use an
approved/certified respirator or equivalent. Gloves.
Protection in Case of a Large Spill:
goggles. Full suit. Vapor and dust respirator. Boots. Gloves. A self contained
breathing apparatus should be used to avoid inhalation of the product. Suggested
protective clothing might not be sufficient; consult a specialist BEFORE

Remarks on Toxicity to Animals: Not
Remarks on Chronic Effects on Humans: May
affect genetic material (mutagenic)
Remarks on other Toxic Effects on Humans:
Potential Health Effects: Skin: Depending on the duration of skin contact, it
may cause reddening, discomfort,
severe irritation, and possible chemical burns. Chemical burns result in
blistering of the skin and possible
scarring. Skin contact may cause allergic sensitization and reaction in
susceptible individuals. Eyes: Contact with eyes will cause severe irritation,
pain, reddening, watering, and possibly burns, corneal damage and blindness.
Inhalation: It may be destructive to the tissues of the mucous membranes and
upper respiratory tract. Symtoms may include respiratory tract irritation or
burning sensation/burns of the mucous membranes, breathing difficulty, coughing,
wheezing, shortness of breath, dyspnea (labored breathing), nasal congestion,
laryngitis, sore throat, headache, nausea, vomiting, and Methemoglobinemia (a
condition that affects the ability of the blood to carry oxygen), and cyanosis
(blue color of the skin due to lack of oxygen). Inhalation of low levels can
cause allergic sensitization and reaction in susceptible individuals. Severe
inhalation over-exposure can be fatal as a result of spasm, inflammation, edema
of the larynx and bronchi, chemical pneumonitis, and pulmonary edema. Symptoms
of exposure may be delayed. Ingestion: Harmful if swallowed. It can cause severe
irritation and burns of the mouth, throat, esophagus, and other tissues of the
digestive tract, nausea, vomiting, diarrhea. Conversion of hemoglobin to
methemoglobin may also occur producing cyanosis (see acute inhalation). It may
also cause a fall in blood pressure, ringing in the ears, shortness of breath,
and affect behavior/central nervous system (headache, vertigo, convulsions).
Ingestion of large volumes may cause coma and be fatal as a result of
circulatory collapse. Chronic Potential Health Effects: Skin: Repeated or
prolonged skin contact to low concentrations may cause dermatitis. Inhalation:
Repeated or prolonged inhalation may cause allergic reaction in sensitized
individuals. Inhalation/Ingestion: Prolonged or repeated exposure by inhalation
or ingestion may affect metabolism (decreased appetite, weight loss), spleen,
thyroid and blood/cause bone marrow damage(decreased leukocyte count, anemia).
It may also cause liver, kidney, and bone marrow damage. This substance is a
blood toxin. Prolonged
