Potential Health Effects
----------------------------------
Inhalation:
Lead can be absorbed through the respiratory system. Local irritation of
bronchia and lungs can occur and, in cases of acute exposure, symptoms such
as metallic taste, chest and abdominal pain, and increased lead blood
levels may follow. See also Ingestion.
Ingestion:
POISON! The symptoms of lead poisoning include abdominal pain and spasms,
nausea, vomiting, headache. Acute poisoning can lead to muscle weakness,
"lead line" on the gums, metallic taste, definite loss of appetite,
insomnia, dizziness, high lead levels in blood and urine with shock, coma
and death in extreme cases.
Skin Contact:
Lead and lead compounds may be absorbed through the skin on prolonged
exposure; the symptoms of lead poisoning described for ingestion exposure
may occur. Contact over short periods may cause local irritation, redness
and pain.
Eye Contact:
Absorption can occur through eye tissues but the more common hazards are
local irritation or abrasion.
Chronic Exposure:
Lead is a cumulative poison and exposure even to small amounts can raise
the body's content to toxic levels. The symptoms of chronic exposure are
like those of ingestion poisoning; restlessness, irritability, visual
disturbances, hypertension and gray facial color may also be noted.
Aggravation of Pre-existing Conditions:
Persons with pre-existing kidney, nerve or circulatory disorders or with
skin or eye problems may be more susceptible to the effects of this
substance.
4. 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 soap and 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 lower and upper eyelids occasionally. Get medical attention
immediately.
5. Fire Fighting Measures
Fire:
Not combustible, but substance is a strong oxidizer and its heat of
reaction with reducing agents or combustibles may cause ignition.
Explosion:
Strong oxidants may explode when shocked, or if exposed to heat, flame, or
friction. Also may act as initiation source for dust or vapor explosions.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire. Do not allow
water runoff to enter sewers or waterways.
Special Information:
Wear full protective clothing and breathing equipment for high-intensity
fire or potential explosion conditions.
6. Accidental Release Measures
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. The
toll free number for the US Coast Guard National Response Center is (800)
424-8802.
7. Handling and Storage
Keep in a tightly closed container. Store in a cool, dry, ventilated area
away from sources of heat or ignition. Protect against physical damage.
Store separately from reactive or combustible materials, and out of direct
sunlight. Isolate from incompatible substances. Areas in which exposure to
lead metal or lead compounds may occur should be identified by signs or
appropriate means, and access to the area should be limited to authorized
persons. 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:
For lead, metal and inorganic dusts and fumes, as Pb:
-OSHA Permissible Exposure Limit (PEL): 0.05 mg/m3 (TWA)
For lead, elemental and inorganic compounds, as Pb:
-ACGIH Threshold Limit Value (TLV): 0.05 mg/m3 (TWA), A3 animal
carcinogen
ACGIH Biological Exposure Indices (BEI): 30 ug/100ml, notation B (see
actual Indices for more information).
For lead, inorganic:
-NIOSH Recommended Exposure Limit (REL): 0.1 mg/m3 (TWA)
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 high efficiency 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 high
efficiency 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.
Other Control Measures:
Eating, drinking, and smoking should not be permitted in areas where solids
or liquids containing lead compounds are handled, processed, or
stored.
See OSHA substance-specific standard for more information on personal
protective equipment, engineering and work practice controls, medical
surveillance, record keeping, and reporting requirements. (29 CFR
1910.1025).
