12


Employee Responsibilities

Consult the company Industrial Hygienist during pre-job planning.

Wear the appropriate PPE for the exposure level including respiratory protection.

Follow safe work practices when performing job tasks involving lead exposure.

Follow proper decontamination and waste disposal procedures.

13


Characteristics of Lead

A soft, bluish-gray, heavy metal

Occurs naturally as an element

Has excellent anti-rust properties

Used in the steel galvanizing process

Used in batteries, solder, paints

Released into the air by work activities involving materials containing lead

14


Terms and Exposure Limits

LeadMetallic lead, all inorganic lead compounds, and organic lead soaps

µg/m3 Micrograms of lead per cubic meter of air

Action level*Employee exposure w/out respirators to an airborne concentration of 30 micrograms (µg/m3) of lead calculated as an 8 hr. TWA

PELPermissible Exposure Limit (50 µg/m3 for lead during 8 hr. TWA; 33 ug/m3 for a 12 hr. TWA

TWATime-weighted average; an exposure limit over a given period of time

Normal air 0.1 to 2.0 µg/m3 OSHA 29 CFR 1926.62(c)(1-3)

OSHA 29 CFR 1926.62(j)1

15



Lead Hazards

16


Hazard Assessment

What are the lead exposure hazards at your location?

What specific work activities may involve the use of lead or lead-containing products?

Who will be involved in the work and how can exposure be eliminated or reduced through hazard controls?

17


Exposure Sources

Fumes: welding with lead; cutting or burning metals or materials containing lead

Dust: sanding, grinding, scraping of lead-based painted surfaces

Mists: spray-painting with lead-based paints

18


Routes of Entry

Inhalation — breathing air with lead-containing dust, particles, or fumes

Ingestion — eating, smoking, chewing tobacco, or applying cosmetics with lead dust on your hands

Small amounts of lead can be eliminated from the body, but what cannot be eliminated will be stored in the organs.

19


Symptoms of Lead Poisoning

Fatigue, dizziness, irritability

Constipation/diarrhea

Stomach aches

Vomiting

Confusion/memory problems

Muscle and joint pains

“Wrist drop”

OSHA 29 CFR 1926.62, Appendix C, II

20


Acute Health Effects

Anemia

Gastrointestinal symptoms

Fetal damage in pregnant women

Large doses can result in:

Seizures

Coma

Death


21


Chronic Health Effects

Brain disorders

Nervous system damage

Gastro-intestinal problems

Reproductive problems

Circulatory system

Kidney damage


22



Control Measures

23


Engineering Controls

Mechanical ventilation

Product elimination or substitution

OSHA 29 CFR 1926.62(e)(3)BP ASH, page 22

24


Administrative Controls

Reduce exposure time through job rotation

Regulated areas

Authorized personnel only

Post warning signs

Check labels

OSHA 29 CFR 1926.62 (e)(4)

25


Personal Protective Equipment

Coveralls or other full body work clothing

Gloves, hats, shoes or disposable shoe covers

Eye protection (face shields, vented goggles)

Hearing protection appropriate to the task

OSHA 29 CFR 1926.62 (g)

26


Respiratory Protection

Respirators must be used when:installing or implementing engineering or work clothing

an employee’s exposure to lead exceeds the PEL

engineering and work-practice controls cannot reduce the exposure to or below the PEL

when the employee requests a respirator.

check your company’s written respiratory program

OSHA 29 CFR 1926.62 (g)

27



Safe Work Practices

28


Good Housekeeping

A rigorous housekeeping program is required to minimize lead exposure.

Keep surfaces free of lead accumulation and clean up spills immediately.

Vacuum with HEPA equipment to minimize dispersal of lead into the workplace.

Do not use compressed air to clean surfaces with suspected lead contamination.

OSHA 29 CFR 1926.62(h)(1-5)

29


Good Housekeeping

Shoveling, dry or wet sweeping, and brushing may be used only where vacuuming or other equally effective methods have been tried and found not to be effective.

All lead debris should be wetted and double-bagged.

Bags and containers should be appropriately labeled as lead-containing wastes.

Tools must be cleaned before taking them out of the work area.

OSHA 29 CFR 1926.62(h)(1-5)

30


Hygiene Facilities and Practices

Consuming food and beverages, smoking, or applying cosmetics will not be allowed in work areas where lead may be present.

Lunchroom and break facilities will be as free from lead contamination as practicable.

OSHA 29 CFR 1926.62(i)(1-5)

31



Employees shall wash their face and hands prior to eating, drinking, smoking, or applying cosmetics.

Surface lead dust must be removed from protective clothing by vacuuming, downdraft booth, or other cleaning method before entering lunchroom facilities or eating areas.

OSHA 29 CFR 1926.62(i)(1-5)

32



Clean change areas will be provided for employees who have potential exposure to lead.

Change areas will be equipped with separate storage facilities for protective equipment storage and street clothes to prevent cross-contamination.

OSHA 29 CFR 1926.62(i)(1-5)

33


Contaminated Reusable PPE

Employees will not be allowed to leave wearing any protective clothing or equipment used during the work day.

They may be expected to shower and change into clean clothes at the end of the work shift.

All employees will follow company decontamination procedures.

OSHA 29 CFR 1926.62(g)(2)(v)

34


Contaminated Reusable PPE

Contaminated reusable PPE must be placed in containers labeled as follows:

CAUTIONClothing contaminated with lead.

Do not remove dust by blowing or shaking.

Dispose of lead-contaminated wash water in accordance with applicable local, state, or federal regulations.

Most PPE used in lead contaminated areas will be disposable.

OSHA 29 CFR 1926.62(g)(2)(v)

35


Site Specific Operations

Know your roles and responsibilities.

Know the site-specific operations at your facility.

Conduct a hazard assessment prior to start of work to determine if lead exposure is a concern.
