Potential Health Effects
----------------------------------
Inhalation:
Inhalation of dust or vapors can cause headache, nausea, vomiting, extensive
sweating, and disorientation. The predominant reaction is delayed intravascular
hemolysis with symptoms of anemia, fever, jaundice, and kidney or liver damage.
Ingestion:
Toxic. Can cause headache, profuse perspiration, listlessness, dark urine,
nausea, vomiting and disorientation. Intravascular hemolysis may also occur
with symptoms similar to those noted for inhalation. Severe cases may produce
coma with or without convulsions. Death may result from renal failure.
Skin Contact:
Can irritate the skin and, on prolonged contact, may cause rashes and allergy.
"Sensitized" individuals may suffer a severe dermatitis.
Eye Contact:
Vapors and solid causes irritation, redness and pain. Very high exposures can
damage the nerves of the eye.
Chronic Exposure:
Has led to cataract formation in eyes. May cause skin allergy.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin, blood or vascular disorders or impaired
respiratory function may be more susceptible to the effects of the substance.
Particularly susceptible individuals are found in the general population, most
commonly in dark skinned races.
4. First
Aid Measures
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. Call a physician.
Ingestion:
Give large amounts of water to drink. Never give anything by mouth to an
unconscious person. Get medical attention.
Skin Contact:
Wash skin with soap or mild detergent and water for at least 15 minutes while
removing contaminated clothing and shoes. Wash clothing before reuse. Call a
physician.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting
lower and upper eyelids occasionally. Get medical attention immediately.
5. Fire
Fighting Measures
Fire:
Flash point: 87C (189F) CC
Autoignition temperature: 526C (979F)
Combustible. May be ignited by heat, sparks or flame. May burn rapidly with
flare-burning effect. Fire may produce irritating or poisonous gases.
Explosion:
Explosive limits, volume % in air: lel: 0.9; uel: 5.9. Above flashpoint,
vapor-air mixtures are explosive within flammable limits noted above. Closed
containers exposed to heat may explode. Contact with strong oxidizers may cause
fire or explosion.
Fire Extinguishing Media:
Dry chemical, foam, water or carbon dioxide. Foam or direct water spray on
molten naphthalene may cause extensive foaming. Molten napthalene spatters in
contact with water; apply water from as far a distance as possible.
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. Vapors can flow along surfaces to
distant ignition source and flash back.
6.
Accidental Release Measures
Remove all
sources of ignition. Ventilate area of leak or spill. Wear appropriate personal
protective equipment as specified in Section 8. Spills: Clean up spills in a
manner that does not disperse dust into the air. Use non-sparking tools and
equipment. Reduce airborne dust and prevent scattering by moistening with
water. Pick up spill for recovery or disposal and place in a closed container.
US Regulations (CERCLA) require reporting spills and releases to soil, water
and air in excess of reportable quantities.
7.
Handling and Storage
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. Keep away
from moisture and oxidizers. 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.
8.
Exposure Controls/Personal Protection
Airborne
Exposure Limits:
- OSHA Permissible Exposure Limit (PEL):
10 ppm, 50 mg/m3.
- ACGIH Threshold Limit Value (TLV):
TWA= 10 ppm, 52 mg/m3
STEL= 15 ppm, 79 mg/m3.
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 respirator with an organic vapor
cartridge and particulate filter (NIOSH type P95 or R95 filter) 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 respirator with an organic vapor cartridge and
particulate filter (NIOSH P100 or R100 filter) 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. Please note that
N series filters are not recommended for this material. For emergencies or
instances where the exposure levels are not known, use a full-face piece
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.
