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 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. Lead acetate can produce acetic acid, carbon monoxide, and toxic fumes
of lead oxide in fire situations.
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, stored in a cool, dry,
ventilated area. Protect against physical damage. 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).
