Potential Health Effects
----------------------------------
Inhalation:
Vapors and mists cause irritation to the respiratory tract. Higher
concentrations can cause burns, pulmonary edema and death. Brief
exposure to 5000 ppm can be fatal.
Ingestion:
Toxic! May cause corrosion to the esophagus and stomach with
perforation and peritonitis. Symptoms may include pain in the mouth,
chest, and abdomen, with coughing, vomiting and collapse. Ingestion of as
little as 3-4 mL may be fatal.
Skin Contact:
Causes irritation and burns to the skin.
Eye Contact:
Vapors cause irritation. Splashes cause severe pain, eye damage, and
permanent blindness.
Chronic Exposure:
Repeated exposure may cause damage to the tissues of the mucous
membranes, upper respiratory tract, eyes and skin.
Aggravation of Pre-existing Conditions:
Persons with pre-existing eye disorders or impaired respiratory function
may be more susceptible to the effects of this material.
4. First Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Call a physician immediately.
Ingestion:
If swallowed, DO NOT INDUCE VOMITING. Give large quantities of
water. Never give anything by mouth to an unconscious person. Get
medical attention immediately.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes while
removing contaminated clothing and shoes. Call a physician, immediately.
Wash clothing before reuse.
Eye Contact:
Immediately flush eyes with gentle but large stream of water for at least
15 minutes, lifting lower and upper eyelids occasionally. Call a physician
immediately. Immediate action is critical to minimize possibility of
blindness.
5. Fire Fighting Measures
Fire:
Autoignition temperature: 651C (1204F)
Flammable limits in air % by volume:
lel: 16; uel: 25
Explosion:
Flammable vapors may accumulate in confined spaces.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire. Use water
spray to blanket fire, cool fire exposed containers, and to flush non-ignited
spills or vapors away from fire.
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.
6. Accidental Release Measures
Ventilate area of leak or spill. Keep unnecessary and unprotected people
away from area of spill. Wear appropriate personal protective equipment
as specified in Section 8. Contain and recover liquid when possible. Do
not flush caustic residues to the sewer. Residues from spills can be diluted
with water, neutralized with dilute acid such as acetic, hydrochloric or
sulfuric. Absorb neutralized caustic residue on clay, vermiculite or other
inert substance and package in a suitable container for disposal.
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.
J. T. Baker NEUTRACIT庐-2 or BuCAIM庐 caustic neutralizers are
recommended for spills of this product.
7. Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area.
Protect against physical damage. Separate from incompatibilities. Store
below 25C. Protect from direct sunlight. Containers of this material may
be hazardous when empty since they retain product residues (vapors,
liquid); observe all warnings and precautions listed for the product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
-OSHA Permissible Exposure Limit (PEL):
50 ppm (NH3)
-ACGIH Threshold Limit Value (TLV):
25 ppm (NH3) (TWA) 35 ppm (STEL)
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 and engineering controls are not feasible,
a full facepiece respirator with an ammonia/methylamine cartridge 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. Neoprene and
nitrile rubber are recommended materials. Polyvinyl alcohol is not
recommended.
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.
