Mercuric Sulfate 7783-35-9 99 - 100% Yes
Inhalation: Mercury vapor is highly toxic via this route. Causes severe
respiratory tract damage. Symptoms include sore throat, coughing, pain,
tightness in chest, breathing difficulties, shortness of breath, headache,
muscle weakness, anorexia, gastrointestinal disturbance, ringing in the ear,
liver changes, fever, bronchitis and pneumonitis. Can be absorbed through
inhalation with symptoms similar to ingestion. Vapor inhalation can burn the
mucous membrane of the nose and throat.
Ingestion: Highly Toxic! Average lethal dose for inorganic mercury salts
is about 1 gram. May cause burning of the mouth and pharynx, abdominal pain,
vomiting, corrosive ulceration, bloody diarrhea. May be followed by a rapid and
weak pulse, shallow breathing, paleness, exhaustion, central nervous system
problems, tremors and collapse. Delayed death may occur from renal failure.
Skin Contact: Causes irritaton and burns to skin. Symptoms include
redness and pain. May cause skin allergy and sensitization. Can be absorbed
through the skin with symptoms to parallel ingestion.
Eye Contact: Causes irritation and burns to eyes. Symptoms include
redness, pain, blurred vision; may cause serious and permanent eye damage.
Chronic Exposure: Chronic exposure through any route can produce central
nervous system damage. May cause muscle tremors, personality and behavior
changes, memory loss, metallic taste, loosening of the teeth, digestive
disorders, skin rashes, brain damage and kidney damage. Can cause skin allergies
and accumulate in the body. Repeated skin contact can cause the skin to turn
gray in color. Not a known reproductive hazard, but related mercury compounds
can damage the developing fetus and decrease fertility in males and females.
Aggravation of Pre-existing Conditions: Persons with nervous disorders,
or impaired kidney or respiratory function, or a history of allergies or a known
sensitization to mercury may be more susceptible to the effects of the
substance.
Inhalation: Remove to fresh air. If not breathing,
give artificial respiration. If breathing is difficult, give oxygen. Get medical
attention immediately.
Ingestion: Induce vomiting immediately as directed by medical personnel.
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. Get medical attention
immediately. Wash clothing before reuse. Thoroughly clean shoes before reuse.
Eye Contact: Immediately flush eyes with plenty of water for at least 15
minutes, lifting lower and upper eyelids occasionally. Get medical attention
immediately.
Fire: Not considered to be a fire hazard.
Explosion: Not considered to be an explosion hazard.
Fire Extinguishing Media: Use any means suitable for extinguishing
surrounding fire. Do not allow water runoff to enter sewers or waterways.
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.
Ventilate area of leak or
spill. Clean-up personnel require protective clothing and respiratory protection
from dust.
Spills: Pick up and place in a suitable container for reclamation or disposal in
a method that does not generate dust. Sprinkle area with sulfur or calcium
polysulfide to suppress mercury.
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.
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from any source of heat or ignition. Protect from light. Follow strict hygiene practices. 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.
Airborne Exposure Limits: - OSHA Acceptable Ceiling
Concentration:
mercury and mercury compounds: 0.1 mg/m3 (TWA), skin- ACGIH Threshold Limit
Value (TLV): inorganic and metallic mercury, as Hg: 0.025 mg/m3 (TWA) skin, A4
Not classifiable as a human carcinogen.- ACGIH Biological Exposure Indices:total
inorganic mercury in urine (preshift): 35 ug/g creatinine;total inorganic
mercury in blood (end of shift): 15 ug/l.
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 particulate
respirator (NIOSH type N100 filters) may be worn for up to 50 times the exposure
limit or the maximum use concentration specified by the appropriate regulatory
agency or respirator supplier, whichever is lowest. If oil particles (e.g.
lubricants, cutting fluids. glycerine, etc.) are present, use a NIOSH type R or
P filter. 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.

fetus, but most of what is known has been learned from experimental animals. See
Chronic Health Hazards.
