Potential Health Effects
----------------------------------
Inhalation:Dust or mist may irritate upper respiratory tract and cause
nasal stiffness, hoarseness, cough and rarely pneumonitis. If toxic amounts are
absorbed, symptoms may parallel those of ingestion.
Ingestion:Ingestion of large amounts of dithiocarbamates may cause
nausea, vomiting, dizziness, salivation, and abdominal pain. If toxic amounts
are absorbed, sweating, weakness, subnormal body temperature, muscle weakness,
incoordination, and ascending paralysis progressing to respiratory paralysis may
occur. Central nervous system damage and neurotoxic effects may be due to carbon
disulfide metabolite. Single doses can cause reduced iodine uptake by the
thyroid gland.
Skin Contact:Dust, mist or solutions may be moderately irritating to the
skin. Some dithiocarbamates have been reported to cause sensitization
dermatitis.
Eye Contact:May cause irritation, redness and pain.
Chronic Exposure:Repeated or prolonged contact may cause sensitization
and poisoning similar to acute poisoning.
Aggravation of Pre-existing Conditions:Itching, inflammation, and
eczematoid dermatitis have resulted when predisposed individuals come in contact
with dithiocarbamates. Antabuse reaction from alcohol consumption following
exposure may produce vasodilation and possible shock. Consumption of any alcohol
should be avoided for at least 3 weeks following acute or chronic ingestion of
dithiocarbamates.
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. Wash clothing before reuse.
Thoroughly clean shoes before reuse. Get medical attention if irritation
develops.
Eye Contact:Immediately flush eyes with plenty of water for at least 15
minutes, lifting upper and lower eyelids occasionally. Get medical attention if
irritation persists.
Fire:Negligible fire hazard in dust form when
exposed to heat or flame. May burn but does not ignite readily.
Explosion:Negligible explosion hazard in dust form when exposed to heat
or flame. Containers may explode in heat or fire.
Fire Extinguishing Media:Dry chemical, foam or carbon dioxide. 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.
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 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.
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Isolate from incompatible substances. To enhance stability, storage below 8C is recommended. 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 Permissible Exposure Limit (PEL):
0.01 mg/m3 (TWA) for silver metal dust and fume as Ag
-ACGIH Threshold Limit Value (TLV):
0.01 mg /m3 (TWA) for soluble silver compounds as Ag
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 protective gloves and clean body-covering clothing.
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.
