Health Effects
Number: LMS0061A
Rev: 2
1. Hazard/Risk Identification
Note:
The recognition, evaluation and control to mitigate potential effects from lead
exposure must be identified and communicated before starting activities where
lead is, may be present, or handled. Handling, storage and disposal of lead waste
shall be performed in compliance with applicable regulations and in a manner that
minimizes any impact to the environment.
Item
Description
1.1
At Suncor, lead may be present in various locations particularly in paints in
buildings existing before 2000.
1.2
At Suncor, lead may be found in building materials, paint in floor, columns and
tanks, tile, roofing materials, plumbing materials, lead sheets, anodes, solder
materials, alloys, fittings, valves, etc.
1.3
Handling of lead-containing material can be a potential health risk and thus care
must be taken to prevent exposures. There are two routes of entry that are of major
concern: inhalation and ingestion.
Breathing in lead dust, fume or vapour may occur during processing, when metal is
being cut, heated, welded or soldered as well as when lead paint coatings are
disturbed. Ingesting lead may occur when eating, drinking or smoking in areas
where lead contamination exists as well as during hand to mouth transfer of lead
during poor hygiene practices.
Harmful effects can follow after high exposure over a short period of time (acute
poisoning), or long-term exposure to lower doses (chronic poisoning).
High exposure over a short period of time can result in a metallic taste in mouth,
gastrointestinal symptoms, such as vomiting, abdominal cramps, constipation, and
diarrhea.
Lead can accumulate in soft tissues (e.g. liver, kidneys, lungs, brain, spleen, muscles
and heart) and ultimately bones and teeth. Small amounts of lead exposure can
accumulate over time which may result in health problems.
Early signs of lead poisoning include tiredness, irritability, muscle and joint pain,
headaches, stomach aches, and cramps. Severe chronic poisoning symptoms include
blue line on the gums, wrist drop (inability to hold the hand extended), severe
abdominal pain and pallor.
Occupational
Exposure Limit
1.4
Lead has been classified by the International Agency for Research on Cancer (IARC)
as a 2A for inorganic lead and 3 for organic lead (probably and not classifiable as
carcinogenic to humans, respectively).
As a result of IARC's classification of lead, Suncor Industrial Hygiene recommends
lead be treated as an ALARA substance where occupational exposures are as low
as reasonably achievable. The 8 hour occupational exposure limit for airborne lead
3
is 0.05mg/m (or 0.006ppm) according to Alberta Occupational Health and Safety
Code, Schedule 1 Table 2. This includes elemental, inorganic, and organic
compounds with the exception of lead chromate and lead arsenate.

2. Recognition
Note: Lead is known to be present in building material (e.g. certain paint and floors in
plants and tanks with paint older than 2000). Any suspected lead-containing
material to be handled or removed shall be analyzed for lead and must be treated
as lead-containing material until proven otherwise.
Item
Description
2.1
The material safety data sheet (MSDS) for new chemical materials submitted for
approval to use on site will be evaluated for the presence of lead. Lead-containing
materials, with the exception of lead-acid batteries, will not be permitted to be used
on site. Leaded paints have previously been a concern; therefore, several non-leaded
paints have been approved for use on site to replace lead paints formerly used.
2.2
Before starting work involving lead based paint on surfaces, likely during the
planning phase, project frontline managers, coordinators or supervisors must
ensure that any activities known or expected to generate airborne levels of lead
have the surface(s) tested for lead paint content.
2.3
Where the identification of lead-containing material is unspecified, a competent
person shall collect bulk samples. Refer to Appendix A for a detailed bulk sampling
procedure.
2.4
All building material (e.g. paint on tanks, walls and floors) suspected to be
lead-containing must be treated as lead-containing until proven otherwise.
2.5
Records collected must be shared with Industrial Hygiene who will assist with
interpretation of results.
3. Evaluation
Air and Bulk
Sampling
Item
Description
3.1
Assessment for the presence of lead in building materials or during demolition /
renovation and occupational air monitoring will be conducted according to the Surface
and Bulk Sampling methods and Air Sampling methods respectively, as outlined in
the Lead at the Worksite bulletin CH061 published by the Government of Alberta,
Employment and Immigration, November 2013.
The most reliable method for the positive identification of lead in surface samples
is through bulk sampling. As a result, unless approved by Industrial Hygiene, bulk
sampling will be identified as the primary route of identification of lead in surfaces
or materials. The material will be considered lead positive at concentrations of
1000 mg/kg (1000 ppm) or higher.
A draft bulk sampling procedure has been attached in Appendix A for reference.

Monitoring and
Surveillance
Description
3.2
Medical monitoring on Suncor employees for lead include blood lead level testing
for lead exposed workers, who could reasonably be expected to have an elevated
body burden of lead.
3.3
At Suncor, lead medical monitoring is available for identified lead exposed Suncor
employees.
• Lead exposed employees are informed of the availabilities of blood lead test.
• Any contractors working with lead material should identify their lead exposed
workers and implement a medical monitoring program for their workers.
3.4
Participation in the medical surveillance program for lead is voluntary for Suncor
employees. Lead remediation contractors are required to meet or exceed this
standard. Details of the Medical Surveillance Program can be found in Appendix B.
Workers choosing not to participate in the health assessment must provide a
written statement indicating their refusal to participate.

Item
4.8
Description
Lead containing material must be removed carefully. Where feasible:
•
•
•
•
Decontamination
and Personal
Hygiene
Practices
restrict air flow from local or general ventilation
minimize use of power tools to reduce the risk of airborne dust
wet surface before scraping especially if no paint removal chemical is being used
enclose any location requiring sandblasting or mechanical grinding.
4.9
Cover all areas immediately adjacent to and below the work with 6 mil polyethylene
film to ensure workers retain wet debris and dust that will be created. In the case of
removal from a wall, the polyethylene drop sheet should extend horizontally on the
ground for a distance equal to one half the height of the surface to be treated.
4.10
Ensure workers place any waste material into 6 mil thick plastic bags, seal with fibre
duct tape, and dispose by careful removal to the Suncor Hazardous Waste Yard.
For lead waste generated at Oil Sands, contact Facilities Services (780-743-6555)
to arrange for appropriate transfer of the waste to the Hazardous Waste Yard. For
lead waste disposal at Firebag contact the RNAS Call Center (780-588-3526) to
arrange for appropriate transfer of the waste to the Hazardous Waste Yard, for
Mackay River contact the RNAS Waste Coordinator (780-588-1462), and for Fort
Hills contact the Waste Management Coordinator
(FHWasteManagement@suncor.com).
4.11
Exposed equipment surfaces must be cleaned to ensure removal of all visible material
using a damp cloth or a 2 stage HEPA vacuum. For a project of more than 1 day,
lead containing debris, paint chips and dust must be cleaned up on at least a daily
basis. After removal of all visible material, the final cleaning will be by successive
HEPA vacuuming and wet mopping with trisodium phosphate solution or mopping
and hosing down to the API sewer system.
4.12
Move the sealed 6 mil plastic bags to a prearranged staging zone within the
restricted area for removal, and wipe clean with a damp cloth. The cloth should
then be placed in the bag and the bag should then be sealed.
4.13
Ensure banner-guard tape is removed immediately after clean-up/removal is
complete and the area is safe.
4.14
Ensure that protective clothing visibly contaminated with lead containing material is
HEPA vacuumed before it is removed. Protective clothing must be removed before
leaving the restricted work area. Disposable coveralls should be used for removals
where exposures above 0.05 mg/m3 (OEL) have been established. They will be
discarded with the waste before leaving the work area.
4.15
Remove respirators only after ensuring the respirator is free of gross contamination.
Clean the respirator with soap and water, wipe dry and place in appropriate storage.
4.16
Personal hygiene is important. Wash hands and face before all breaks and at the
end of the day. Showering is preferable if available and is mandatory when
exposures exceed 0.05 mg/m3 (OEL). Any reusable clothing must be laundered
before reuse.

APPENDIX A – Lead Bulk Sampling Procedure of Suspected Lead Containing Paint
This document provides user with the guidelines and requirements for bulk sampling of suspected lead containing
products and personal protective equipment required to perform the work safely. Areas with known
lead-containing paints and products have been confirmed in Plant 31. Suspected lead-containing paints may be
located in older plants and facilities such as in Upgrading 1 and certain plants in Extraction. Any paint potentially
containing lead need to be bulk sampled to confirm if it is more than 1000mg/kg (1000ppm) lead.
1. Pre-Sampling Specifics:
a. Paint Chip Sampling:
i. Paint-chip samples may be collected by any worker, who has reviewed this procedure. Ensure the
required PPE and precautions highlighted in this procedure are used.
ii. Paint-chip samples should contain all layers of paint (not just peeled layers) and must always include
the bottom layer.
iii. Paint from 4 square inches (25 square centimetres) should provide a sufficient quantity for laboratory
analysis. Smaller surface areas may be used, if the laboratory indicates that a smaller sample is
acceptable.
iv. In all cases, the surface area sampled must be recorded. Be as accurate as possible.
b. Number of samples required:
If the area is a uniform layer of paint or colouring without any patches or changes in visible thickness the
following samples are suggested and up to the Industrial Hygienists discretion:
i. If the total surface area is <10square feet, take 1 sample.
ii. If the total surface area is between 10 square feet and 100 square feet, take 3 samples.
iii. If the total surface area is >100 square feet, break the area down into sections less than 100 square
feet and take 3 samples per area.
If the area is non-uniform in paint layer, follow the above sampling strategy for each different patch of
paint encountered.
c.
For non-paint bulk materials, please consult your Industrial Hygienist for a path forward.
2. Records:, The following information for bulk samples must be recorded and provided to the Industrial
Hygienist by persons collecting bulk samples:
a. Who performed the sampling
b. Date &Time
c.
Sample Number
d. Plant # and Floor #
e. Paint condition and colour
f.
Sample location description (and drawing if possible). Use N/W/E/S as much as possible and reference
vessel/equipment numbers when possible.

LMS0019A requirements, yellow flagging is sufficient at a distance of 5 meters from perimeter of work
area.
b. Assess the number of samples to be taken, contact your Industrial Hygienist if required.
c.
Prepare sampling bags/containers with sample numbers, date, time and location of sample. For location
of sample, be as specific as possible.
d. If the paint to be sampled seems friable (i.e. will easily lead to dust generating in the immediate area),
place a drop sheet to collect dust that may fall from the sampling location.
e. Paint Chip sampling:
i. A metal scraper can be used to remove paint chips or paint from the sampling areas in question.
ii. If the sampling area seems friable, water should be sprayed over the area to prevent dust becoming
airborne.
iii. Paint-chip samples should contain all layers of paint (not just peeled layers) and must always include
the bottom layer.
iv. Paint from 4 square inches (25 square centimetres) should provide a sufficient quantity for laboratory
analysis.
v. 4 square inches of paint can be any shape as long as the area is as close to 4 square inches as
possible.
vi. Samples containers must be sealed with tape. Ensure sample numbers and descriptions are not
affected by seal tape and can still be read easily.

Blood lead testing
Results of the initial blood lead testing will be considered the baseline level to which all future blood lead levels
will be compared.
Periodic Medical Assessment
3
A periodic medical assessment will be conducted on workers exposed to lead in excess of 50 µg/m for more than
30 days per year. A blood lead test will be conducted for these workers, the frequency of which will be determined
by the results. The frequency of testing is outlined in Table 1 Blood Lead Levels for Workers, of this Appendix.
Pregnant workers or female workers of childbearing age who are considering becoming pregnant will need to
meet more stringent criteria, as outlined in Table 2: Blood Lead levels for pregnant workers and female workers of
childbearing age.
1. If blood lead levels are below 1.5 micromoles per litre (μmol/L), no further action is required.
2. If blood lead levels exceed 1.5 μmol/L, additional medical testing may be conducted and includes:
•
Occupational history
•
Physical exam and blood pressure evaluation
•
Complete blood count with differential (CBC and Diff.) for hematocrit, hemoglobin and red cell indices.
This testing is completed as lead affects the ability to make red blood cells.
•
Routine urinalysis, blood urea nitrogen and serum creatinine. High levels of lead can affect kidney
function.
•
Peripheral smear morphology is only completed if the blood tests show abnormal results.
3. If blood lead levels are 2.5 μmol/lL or greater, worker must be removed from exposure and monitored until
blood level return to acceptable levels, less than 2.0 μmol/L.
