**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Danger of cumulative effects. Limited evidence of a carcinogenic
effect. May cause harm to the unborn child. Possible risk of impaired
fertility. Very toxic to aquatic organisms, may cause long-term
adverse effects in the aquatic environment.Oxidizer.Dangerous for the
environment.Cancer suspect agent.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea.
Inhalation:
Causes respiratory tract irritation. May cause effects similar to
those described for ingestion.
Chronic:
May cause cancer in humans. Repeated exposure may cause
sensitization dermatitis. Chronic exposure to lead may result in
plumbism which is characterized by lead line in gum, headache, muscle
weakness, mental changes. Laboratory experiments have resulted in
mutagenic effects. Lead salts have been reported to cross the
placenta and induce embryo- and feto- mortality.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
Persons with asthma, allergies, and know sensitization to chromic
acid or chromates may be at increased risk from exposure to this
product. Treat symptomatically and supportively.
Antidote:
The use of d-Penicillamine as a chelating agent should be determined
by qualified medical personnel. The use of Calcium disodium EDTA as a
chelating agent should be determined by qualified medical personnel.
The use of Dimercaprol or BAL (British Anti-Lewisite) as a chelating
agent should be determined by qualified medical personnel.
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Combustion generates toxic fumes. Oxidizer. Greatly
increases the burning rate of combustible materials. May accelerate
burning if involved in a fire.
Extinguishing Media:
Use water only! Cool containers with flooding quantities of water
until well after fire is out. For large fires, flood fire area with
water from a distance. Do NOT use dry chemicals, CO2, Halon or
foams.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Avoid generating dusty conditions. Provide ventilation. With a clean
shovel, carefully pick up the material and place it into a clean dry
container and cover for disposal. Keep combustibles (wood, paper,
oil, etc.,) away from spilled material.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use only in a well-ventilated area. Minimize dust
generation and accumulation. Avoid contact with eyes, skin, and
clothing. Empty containers retain product residue, (liquid and/or
vapor), and can be dangerous. Keep container tightly closed. Avoid
ingestion and inhalation. Keep from contact with clothing and other
combustible materials. Do not pressurize, cut, weld, braze, solder,
drill, grind, or expose empty containers to heat, sparks or open
flames.
Storage:
Do not store near combustible materials. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29
CFR 1910.134 and ANSI Z88.2 requirements or European
Standard EN 149 must be followed whenever workplace
conditions warrant a respirator's use.

LD50/LC50:
CAS# 7758-97-6: Oral, mouse: LD50 = >12 gm/kg.
Carcinogenicity:
Lead(II) chromate -
ACGIH: A3 - Confirmed animal carcinogen with unknown relevance to
California: carcinogen, initial date 2/27/87 (listed as Chromium (VI)
NTP: Known carcinogen
IARC: Group 1 carcinogen (listed as Chromium (VI) compounds).
Other:
See actual entry in RTECS for complete information.
**** SECTION 12 - ECOLOGICAL INFORMATION ****
Ecotoxicity:
Chromium in soil can be transported to the atmosphere by way of
aerosol formation. Chromium is also transported from soil through
runoff and leaching of water. Runoff could remove both chromium ions
and bulk precipitates of chromium, with final deposition on either a
different
land area or a water body. Leaching of lead can be
relatively rapid from some soils, especially at highly contaminated
sites or landfills.
