Lead Peroxide 1309-60-0 95 - 100% Yes
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.
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.
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.
Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8.
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.
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
and engineering controls are not feasible, a half-face high efficiency
particulate respirator (NIOSH type N100 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
high efficiency particulate respirator (NIOSH type N100 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.
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.
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).
