Below is the Ammonium Chloride MSDS.


MSDS Number: mza5724


Product Identification
Synonyms: sal ammoniac; ammonium muriate
CAS NO: 12125-02-9
Molecular Weight: 53.49
Chemical Formula: nh4cl
Composition/Information on Ingredients Ingredient
CAS No. Percent Hazardous
----------------------------- --------- --------- ------------
Ammonium Chloride 12125-02-9 99-100% Yes

Hazards Identification
Emergency Overview
------------------------------
WARNING! CAUSES IRRITATION TO SKIN, EYES AND RESPIRATORY TRACT. HARMFUL IF SWALLOWED OR INHALED.
------------------------------
Health Rating: 1 - slight
Flammability Rating: 0 - none
Reactivity Rating: 0 - none
Contact Rating: 1 - slight
Lab Protective Equip: goggles; lab coat
Storage Color Code: orange (general storage)

Potential Health Effects
Inhalation: causes irritation to the respiratory tract. Symptoms may include coughing, shortness of breath.

Ingestion: causes irritation to the gastrointestinal tract. Symptoms may include nausea, vomiting and diarrhea.

Skin Contact: causes irritation to skin. Symptoms include redness, itching, and pain.

Eye Contact: causes irritation, redness, and pain.

Chronic Exposure: no information found.

Aggravation of Pre-existing Conditions: no information found.
First Aid Measures
Inhalation: remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.

Ingestion: induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person. Get medical attention.

Skin Contact: immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse.

Eye Contact: immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower eyelids occasionally. Get medical attention.
Fire Fighting Measures
Fire: not considered to be a fire hazard. At fire temperatures ammonium chloride begins to corrode metals and may dissociate into ammonia and hydrogen chloride. Mixtures of about 16% to 25% (by volume) ammonia gas in air are flammable.

Explosion: not considered to be an explosion hazard.

Fire extinguishing Media: use any means suitable for extinguishing surrounding fire. Water spray may be used to keep fire exposed containers cool.

Special Information: in the event of a fire, wear full protective clothing and niosh-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.
Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in 8. Spills: sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust dispersal. Us regulations (cercla) require reporting spills and releases to soil, water and air in excess of reportable quantities. The toll free number for the us coast guard national response center is (800) 424-8802.
Handling and Storage
Keep in a tightly closed container. Protect from physical damage. Store in a cool, dry, ventilated area away from sources of heat, moisture and incompatibilities. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
Exposure Controls/Personal Protection
Airborne Exposure Limits:
Ammonium Chloride:
-ACGIH Threshold Limit Value (TLV): 10 mg/m3 (twa); 20 mg/m3 (stel) fume

Ventilation System: a system of local and/or general exhaust is recommended to keep employee exposures below the airborne exposure limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, "industrial ventilation, a manual of recommended practices", most recent edition, for details.

Personal Respirators (niosh approved): if the exposure limit is exceeded, a half-face dust/mist respirator may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face piece dust/mist respirator may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency, or respirator supplier, whichever is lowest. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. Warning: air-purifying respirators do not protect workers in oxygen-deficient atmospheres.

Skin Protection: wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.

Eye Protection: use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Physical and Chemical Properties
appearance: white powder
boiling point: 520C (968f)
odor: odorless.
melting point: 338C (640f) sublimes.
Solubility: 29.7G/100g water @ 0c (32f)
vapor density (air=1): 1.9
Specific gravity: 1.53
vapor pressure (mm hg): 1.0 @ 160C (320f)
ph: evaporation rate (buac=1): 5.5 (1% Aq.Sol.); 5.1 (3% No information found. Aq.Sol.); 5.0 (10% Aq.Sol.)
% Volatiles by volume @ 21c (70f): 0
Stability and Reactivity
Stability: stable under ordinary conditions of use and storage.

Hazardous decomposition products: involvement in a fire causes decomposition to form hydrogen chloride and ammonia.

Hazardous polymerization: will not occur.

Incompatibilities: concentrated acids, strong bases, silver salts, potassium chlorate, ammonium nitrate, bromine trifluoride and iodine heptafluoride. Ammonium chloride reacts explosively with potassium chlorate or bromine trifluoride, and violently with bromide pentafluoride, ammonium compounds, nitrates, and iodine heptafluoride. Explosive nitrogen trichloride may result from reaction of ammonium chloride and hydrogen cyanide.

Conditions to avoid: heat, moisture, incompatibles.
