Uses of Lead in Industry
Building construction materials Plumbing Paint Other uses
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Workplace Lead Exposure
Demolition or construction work on lead painted surfaces
Smelter operations Construction—plumbing, welding, painting Lead recovery operations Firing ranges
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Risks of Construction Exposure
Demolition or salvage Removal or encapsulation Renovation, repair, or alteration of structures Installation of lead products Lead emergency cleanup Transportation, disposal, storage, or
containment

How Lead Enters the Body
Dust or fumes Inhalation Ingestion Skin contact
not hazardous
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Operations Generating Dust and Fumes
Abrasive blasting Flame torch cutting,
welding, heat guns Sanding, scraping,
grinding Maintaining
lead equipment
Symptoms of Lead Exposure
Report these symptoms of exposure immediately:
–Loss of appetite–Metallic taste in mouth
–Anxiety–Stomach cramps–Pale skin–Tiredness
–Headache–Nervous irritability–Muscle and joint pain–Tremors–Numbness–Dizziness
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Short-Term Lead Exposure
Lead is a poison Health effects depend
on how much lead is absorbed
Seizures, coma, and death
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Long-Term Lead Exposure
Lead builds up in the body over time
Anemia Damage to
nervous system Damage to kidneys
and other organs Damage to reproductive system
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Permissible Exposure Limit
50 ug/m3 over an 8-hour period Restricted area Signs posted Respirators required Plans to reduce exposure Written compliance program Showers, changing rooms, and lunchrooms
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Action Level
30 µg/m3 over an 8-hour period Reduce lead levels Provide medical exam before starting job Provide blood tests Monitor the air Inform employees of lead hazards Provide access to medical records

Quiz
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Control Lead Exposure
Restrict access Post warning signs Install ventilation systems Implement job rotation Practice proper housekeeping and hygiene
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Ventilation
Mechanical system used with enclosures
Local portable system Shrouded power tools Measurements taken
every three months
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Respirators
Use as a last resort Voluntary use
is permitted Change cartridges
at any time Remove properly to prevent contamination
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Respirators and The Construction Standard
Assumes lead levels for various tasks
Half-mask, air purifying or cartridge
Powered air-purifying Supplied-air respirator
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Other PPE
Coveralls Gloves Hats Shoe covers Face shields
or goggles
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
PPE Cleaning and Disposal
Remove dust with a vacuum Do not remove lead by blowing or shaking Dispose of contaminated clothing properly Label disposal and laundry containers Dispose of contaminated wash water properly
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Housekeeping and Hygiene
Keep surfaces free of lead Remove lead dust with a HEPA vacuum Keep food, beverages, or tobacco out of
high lead areas Wash before eating, smoking, or applying
cosmetics Don’t wear lead-contaminated clothing home Store work clothes separate from personal
clothes
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Medical Surveillance
Employers must provide a medical exam for employees when:
–First assigned to work near lead–Exposed to the action level for more than 30 days a year
–Symptoms are reported–High lead levels are present in blood–Employees request medical advice
Employees must be informed of blood test results
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Removal from Lead Exposure
Employees must be removed from lead exposure when:
–Blood levels are above 50 µg–Lead exposures cannot be brought below action level
–Employee has increased risk of health impairment Employees removed because of lead exposure:
–Must retain pay, seniority, and benefits–May return to job once blood levels are reduced–May be given drug therapy to reduce blood lead levels
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Air Monitoring
Required if there are indications of lead Performed every 3 months if above the PEL Performed every 6 months if above the
action level Required if there are changes in the
workplace Results provided to employees
Worker Protection Plan
Hazard determination Engineering and
work practice controls Signs Respiratory protection Protective clothing
and equipment
Housekeeping Hygiene facilities
and practices Medical surveillance Training
11006130/0303 Copyright ©2003 Business and Legal Reports, Inc.
Emergencies
Sweep spills into sealed containers
Do not allow lead to enter environment
For inhalation, get fresh air and medical attention
For ingestion, rinse mouth, induce vomiting, get medical attention
