BLR’s Safety Training Presentations

Lead Safety29 CFR 1910.1025,

29 CFR 1915.1025, 29 CFR 1926.62


Goals

Lead exposures, health hazards, and exposure limits

Controlling lead exposure, medical surveillance, and air monitoring

Quiz


Uses of Lead in Industry

Building construction materials Plumbing Paint Other uses


Workplace Lead Exposure

Demolition or construction work on lead painted surfaces

Smelter operations Construction—plumbing, welding, painting Lead recovery operations Firing ranges


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


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


Short-Term Lead Exposure

Lead is a poison Health effects depend

on how much lead is absorbed

Seizures, coma, and death


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


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


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


Goals



Quiz


Control Lead Exposure

Restrict access Post warning signs Install ventilation systems Implement job rotation Practice proper housekeeping and hygiene


Ventilation

Mechanical system used with enclosures

Local portable system Shrouded power tools Measurements taken

every three months


Respirators

Use as a last resort Voluntary use

is permitted Change cartridges

at any time Remove properly to prevent contamination


Respirators and The Construction Standard

Assumes lead levels for various tasks

Half-mask, air purifying or cartridge

Powered air-purifying Supplied-air respirator


Other PPE

Coveralls Gloves Hats Shoe covers Face shields

or goggles


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


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


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


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


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


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


Goals
