provided. Further action will be the responsibility of the medical specialist.
鈥? If medical attention is not available on the worksite or surroundings send the
patient to a hospital together with a copy of the MSDS.
EYE
If this product comes in contact with the eyes:
鈥? Immediately hold eyelids apart and flush the eye continuously with running
water.
鈥? Ensure complete irrigation of the eye by keeping eyelids apart and away from
eye and moving the eyelids by occasionally lifting the upper and lower lids.
鈥? Continue flushing until advised to stop by the Poisons Information Centre or a
doctor, or for at least 15 minutes.
鈥? Transport to hospital or doctor without delay.
鈥? Removal of contact lenses after an eye injury should only be undertaken by
skilled personnel.
SKIN
If skin contact occurs:
鈥? Immediately remove all contaminated clothing, including footwear
鈥? Flush skin and hair with running water (and soap if available).
鈥? Seek medical attention in event of irritation.
INHALED
鈥? If fumes or combustion products are inhaled remove from contaminated area.
鈥? Lay patient down. Keep warm and rested.
鈥? Prostheses such as false teeth, which may block airway, should be removed,
where possible, prior to initiating first aid procedures.
鈥? Apply artificial respiration if not breathing, preferably with a demand valve
resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if
necessary.
鈥? Transport to hospital, or doctor, without delay.
NOTES TO PHYSICIAN
鈥? Gastric acids solubilise lead and its salts and lead absorption occurs in the
small bowel.
鈥? Particles of less than 1 um diameter are substantially absorbed by the alveoli
following inhalation.
鈥? Lead is distributed to the red blood cells and has a half-life of 35 days. It
is subsequently redistributed to soft tissue & bone-stores or eliminated. The
kidney accounts for 75% of daily lead loss; integumentary and alimentary losses
account for the remainder.
鈥? Neurasthenic symptoms are the most common symptoms of intoxication. Lead
toxicity produces a classic motor neuropathy. Acute encephalopathy appears
infrequently in adults. Diazepam is the best drug for seizures.
鈥? Whole-blood lead is the best measure of recent exposure; free erythrocyte
protoporphyrin (FEP) provides the best screening for chronic exposure. Obvious
clinical symptoms occur in adults when whole-blood lead exceeds 80 ug/dL.
鈥? British Anti-Lewisite is an effective antidote and enhances faecal and urinary
excretion of lead. The onset of action of BAL is about 30 minutes and most of
the chelated metal complex is excreted in 4-6 hours, primarily in the bile.
Adverse reaction appears in up to 50% of patients given BAL in doses exceeding 5
mg/kg. CaNa2EDTA has also been used alone or in concert with BAL as an antidote.
D-penicillamine is the usual oral agent for mobilisation of bone lead; its use
in the treatment of lead poisoning remains investigational.
2,3-dimercapto-1-propanesulfonic acid (DMPS) and dimercaptosuccinic acid (DMSA)
are water soluble analogues of BAL and their effectiveness is undergoing review.
As a rule, stop BAL if lead decreases below 50 ug/dL; stop CaNa2EDTA if blood
lead decreases below 40 ug/dL or urinary lead drops below 2 mg/24hrs.

FOOTNOTES
1 PROTECTIVE ACTION ZONE is defined as the area in which people are at risk
of harmful exposure. This zone assumes that random changes in wind direction
confines the vapour plume to an area within 30 degrees on either side of the
predominant wind direction, resulting in a crosswind protective action distance
equal to the downwind protective action distance.
2 PROTECTIVE ACTIONS should be initiated to the extent possible, beginning with
those closest to the spill and working away from the site in the downwind
direction. Within the protective action zone a level of vapour concentration
may exist resulting in nearly all unprotected persons becoming incapacitated
and unable to take protective action and/or incurring serious or irreversible
health effects.
3 INITIAL ISOLATION ZONE is determined as an area, including upwind of the
incident, within which a high probability of localised wind reversal may
expose nearly all persons without appropriate protection to life-threatening
concentrations of the material.
4 SMALL SPILLS involve a leaking package of 200 litres (55 US gallons) or less,
such as a drum (jerrican or box with inner containers). Larger packages leaking
less than 200 litres and compressed gas leaking from a small cylinder are also
considered "small spills".
LARGE SPILLS involve many small leaking packages or a leaking package of
greater than 200 litres, such as a cargo tank, portable tank or a "one-tonne"
compressed gas cylinder.

The lead concentration in air is to be maintained so that the lead concentration
in workers' blood remains below 0.060 mg/100 g of whole blood. The recommended
TLV-TWA has been derived following a review of reports of adverse effects on
reproduction, blood-pressure and other end-points of toxicity. A particular
focus was an assessment of pre-natal blood lead (PbB) levels and post-natal
cognitive levels. The fact that lead is a cumulative toxicant which can produce
subtle, persistent and apparently permanent effects in the off-spring of lead
exposed women is of particular concern. A current view holds that the
identification of the PbB levels, that are protective during a working lifetime,
is a necessary prerequisite in the recommendation of the TLV because PbB values,
rather than workplace air lead concentrations, are more clearly related to
adverse health effects.

or restrictions on use, should be created for each workplace or task. This
should include a review of lens absorption and adsorption for the class of
chemicals in use and an account of injury experience. Medical and first-aid
personnel should be trained in their removal and suitable equipment should be
readily available. In the event of chemical exposure, begin eye irrigation
immediately and remove contact lens as soon as practicable. Lens should be
removed at the first signs of eye redness or irritation - lens should be removed
in a clean environment only after workers have washed hands thoroughly. [CDC

ENGINEERING CONTROLS
Use in a well-ventilated area.
鈥? Local exhaust ventilation is required where solids are handled as powders or
crystals; even when particulates are relatively large, a certain proportion will
be powdered by mutual friction.
鈥? Exhaust ventilation should be designed to prevent accumulation and
recirculation of particulates in the workplace.
鈥? If in spite of local exhaust an adverse concentration of the substance in air
could occur, respiratory protection should be considered. Such protection might
consist of:
(a): particle dust respirators, if necessary, combined with an absorption
cartridge;
(b): filter respirators with absorption cartridge or canister of the right type;
(c): fresh-air hoods or masks
鈥? Build-up of electrostatic charge on the dust particle, may be prevented by
bonding and grounding.
鈥? Powder handling equipment such as dust collectors, dryers and mills may
require additional protection measures such as explosion venting.
Air contaminants generated in the workplace possess varying "escape" velocities

which, in turn, determine the "capture velocities" of fresh circulating air
required to efficiently remove the contaminant.
Type of Contaminant: Air Speed:
direct "spray " spray painting in 1-2.5 m/s (200-500 f/min.)
shallow "booths " drum "filling "
conveyer "loading " crusher "dusts "
gas discharge (active generation into
zone of rapid air motion)
grinding " abrasive "blasting " 2.5-10 m/s (500-2000 f/min.)
"tumbling " high speed wheel generated
dusts (released at high initial
velocity into zone of very high rapid
air motion).
Within each range the appropriate value depends on:
Lower end of the range Upper end of the range
1: Room air currents minimal or 1: Disturbing room air currents
favourable to capture
2: Contaminants of low toxicity or of 2: Contaminants of high toxicity
nuisance value only
3: Intermittent, low production. 3: High production, heavy use
4: Large hood or large air mass in 4: Small hood-local control only
motion
Simple theory shows that air velocity falls rapidly with distance away from the
opening of a simple extraction pipe. Velocity generally decreases with the
square of distance from the extraction point (in simple cases). Therefore the
air speed at the extraction point should be adjusted, accordingly, after
reference to distance from the contaminating source. The air velocity at the
extraction fan, for example, should be a minimum of 4-10 m/s (800-2000 f/min)
for extraction of crusher dusts generated 2 metres distant from the extraction
point. Other mechanical considerations, producing performance deficits within
the extraction apparatus, make it essential that theoretical air velocities are
multiplied by factors of 10 or more when extraction systems are installed or
used.

POTENTIAL HEALTH EFFECTS
ACUTE HEALTH EFFECTS
SWALLOWED
Considered an unlikely route of entry in commercial/industrial environments.
The material is moderately discomforting and toxic if swallowed and may be fatal
if swallowed in large quantity.
Ingestion may result in nausea, abdominal irritation, pain and vomiting.
EYE
The dust may be discomforting and may be abrasive and harmful following
absorption and is capable of causing a mild, temporary redness of the
conjunctiva (similar to wind-burn), temporary impairment of vision and/ or other
transient eye damage/ ulceration.
SKIN
The dust may be discomforting to the skin and it is slowly absorbed by the skin.
Bare unprotected skin should not be exposed to this material.
Toxic effects may result from skin absorption.
The material may cause skin irritation after prolonged or repeated exposure and
may produce on contact skin redness, swelling, the production of vesicles,
scaling and thickening of the skin.
INHALED
The dust may be discomforting to the upper respiratory tract and may be harmful
if inhaled.
Persons with impaired respiratory function, airway diseases and conditions such
as emphysema or chronic bronchitis, may incur further disability if excessive
concentrations of particulate are inhaled.
CHRONIC HEALTH EFFECTS
Principal routes of exposure are usually by inhalation of generated dust, skin
contact with the material and accidental ingestion. Lead, in large amounts, can
affect the blood, nervous system, heart, glands, immune system and digestive
system. Anaemia may occur. If untreated muscles may become paralysed, and there
may be brain damage. Symptoms include joint and muscle pain, weakness in the
back of the forearm and wrist and in the shin muscles, headaches, dizziness,
abdominal pain, diarrhoea or constipation, nausea, vomiting, blue line on gums,
sleep disturbance and a metallic taste in the mouth. The pressure in the brain
may increase with high doses, and cause brain damage, coma, and death. Early
signs include loss of appetite and weight, constipation, tiredness and
irritability, headache, weakness. Later there may be vomiting, nervousness, and
muscle pains in the arms and legs. Serious cases cause severe vomiting,
inco-ordination, stupor, permanent eye damage, high blood pressure, multiple

nerve disorders of the head resulting in paralysis and loss of reflexes,
delirium, convulsions and coma. The kidneys may become irreversibly damaged, and
the nervous system may become affected causing mental retardation, cerebral
palsy, and jerks and seizures. Lead can cross the placenta, and cause
miscarriage, stillbirths and birth defects. Exposure before birth can cause
mental retardation, behavioural disorders and infant death. Lead can also cause
reduced sex drive, impotence, sterility and damage the sperm of males,
increasing the potential for birth defects. Periods in women can also be
affected. Lead can accumulate in the skeleton for a very long time.

Section 12 - ECOLOGICAL INFORMATION
Marine Pollutant:Yes
Lead is primarily an atmospheric pollutant that enters soil and water as
fallout, a process determined by physical form and particle size. Lead in the
form of alkyls has been introduced to the environment primarily from leaded
petrol. These are converted to water-soluble lead compounds of high toxicity and
availability to plants. Such compounds easily leach from soil to contaminate
water sources close to highways. Lead that has entered the aquatic system from
run-off or as fallout of insoluble precipitates is found in sediments. The
biological methylation of inorganic lead by lake sediment micro-organisms has
been demonstrated although its significance is not entirely clear. Other forms
of soluble or insoluble lead may also enter the environment and undergo
bioaccumulation through a series of biological incidents.
