Ventiliation: of non-sparking or intrinsically safe ventilation systems and
equipment if explosive concentrations of material are pres-
ent. Ensure compliance with applicable exposure limits.
Wear safety glasses with side shields as a minimum level of
protection. If splash or splatter is possible, wear chemical/
splash resistant safety goggles and or face shield. Emer-

provided in the immediate work area as per the ANSI Z358.1
guidelines.

Wear appropriate chemical resistant gloves for type of expo-
Gloves: sure. (Butyl or nitrile glove are resistant to incidental contact
with toluene)
Refer to 29CFR1910.134 for selection of appropriate
respiratory protection. Organic vapor cartridge with a 陆

inorganic Lead compounds); ACGIH: A3 鈥? Animal carcinogen (lead and inorganic lead
Carcinogen status: compounds) Renal tumors were produced in animals by lead acetate, subacetate and
phosphate given orally, subcutaneously or intraperitoneally. No evaluation could be made
of the carcinogenicity of other lead compounds.
Absorption of large amounts of lead may cause a metallic taste, thirst, burning sensation
in the mouth and threat, salivation, abdominal pain with sever colic, vomiting, diarrhea of
black or bloody stools, constipation, fatigue, sleep disturbances, dullness, restlessness,
Acute Inhalation Exposure: irritability, memory loss, loss of concentration, delirium, oliguria often with hematuria and
albuminuria, encephalopathy with visual failure, paresthesias, muscle pain and weakness,
convulsions, and paralysis.
Prolonged or repeated exposure to low level of lead may result in an accumulation in body
tissues and exert adverse effects on the blood, nervous system, heart, endocrine and im-
mune systems, kidneys, and reproduction. Early stages of lead poisoning, 鈥減lumbism鈥?, may
be evidenced by anorexia, weight loss, constipation, apathy or irritability, occasional vomit-
ing, fatigue, headache, weakness, metallic taste in the mouth, gingival lead line in persons
Chronic Inhalation Exposure: with poor dental hygiene, and anemia. Loss of recently developed motor skills is generally
observed only in children. Lead crosses the placenta and may affect the fetus causing birth
defects, mental retardation, behavioral disorders, and death during the first year of child-
hood. Animal studies indicate that reproductive effects may be additive if both parents are
exposed to lead.
Contact with lead powders or dust may be irritating. Lead is not absorbed through the skin,
Skin exposure: but may be transferred to the mouth inadvertently by cigarettes, chewing tobacco, food, or
make up.
Eye exposure: Irritating effect.
Sensitization: No sensitizing effects known.
PMMA
No significant adverse effects are known. In solid form, may cause irritation when inhaled
Health effects: or ingested or with eye and skin contact. No data available for chronic or acute effects.
Section 12 - Ecological Information
Do not allow material to be released to the environment (ground, air or water bodies). Lead can be toxic
to a host of organisms and should not be released to the environment. Toluene is relatively non-persistant
in the environment and accumulates very little in the bodies of living organisms.
