Occupational Lead Poisoning

  • Date: Jan 01 1990
  • Policy Number: 9006

Key Words: Occupational Safety And Health Administration, Lead Exposure, Lead Poisioning

The American Public Health Association,

Noting that in 1978 the Occupational Safety and Health Administration (OSHA) promulgated a comprehensive lead standard, based on the renal, neurologic, hematologic, and reproductive toxicity of lead to both male and female workers;1 and realizing that over 800,000 workers in over 100 different occupations are currently exposed to lead; and

Noting that several state health departments and occupational clinics have recently documented cases of acute and chronic occupational lead toxicity2 despite objectives of the US Public Health Service to eliminate occupational lead poisoning by 1990,3 while the full extent of occupational lead poisoning remains unknown, in part because only seven states require reporting of elevated blood lead levels,2 and most practitioners are inadequately trained about occupational disease;4 and

Recognizing that despite the passage of an OSHA standard, toxicity has been documented at blood lead levels well below current medical removal levels,5 and that the organic lead-using and construction industries are exempt from coverage,1 and required monitoring results are not centrally collected or used for preventive purposes, and employer compliance with the standard is incomplete especially in small-size businesses;6 and

Understanding that many lead-exposed workers are not protected or trained on safe techniques, resulting in poisoning of workers, household residents,7-13 family members,14,15 and environmental contamination; and

Noting that some employers have responded to the reproductive hazards of lead by adopting policies which remove female employees from hazardous areas or require sterilization, rather than eliminating the hazard, and that these exclusionary policies have largely affected women in male-dominated, higher-paying occupations,16 and noting that there have been inconsistent appellate court rulings on whether such policies are sex discriminatory;17,18 and

Noting that minority workers are at increased risk of lead poisoning and may face discrimination and other barriers in exercising their rights to protection;2 and

Noting that research has implicated lead as a cause of chronic neurologic, renal, cardiovascular, and reproductive damage,19,20 but that long-term, low level effects have been inadequately studied;21 therefore:

1. Urges the Federal Government to:
a) Expand the protective provisions of the Lead Standard to construction and organic-lead exposed workers, including specific requirements for abatement work, as has been done in Maryland;22,23
b) Increase emphasis on enforcement of the Lead Standard, and for employer/employee education on lead hazards, legal rights and responsibilities in the language and manner that will reach the target groups;
c) Ban all non-essential uses of lead and promote development and substitution of safe alternatives;
d) Consider revisions in the OSHA Lead Standard to reflect current scientific evidence of toxicity, and require thorough job analysis and control measures where levels are elevated.
2. Urges federal and state governments to provide incentives to small businesses in need of assistance to control lead;
3. Reaffirms its support of a mandatory, uniform, laboratory-based reporting system for occupational disease including lead poisoning,24 to include: reporting of all monitoring results, mandatory industrial hygiene and medical follow-up, and funding for such activities;
4. Reaffirms its support for education and safe lead abatement programs;25
5. Recommends that the National Institute for Occupational Safety and Health sponsor educational programs for health care practitioners to better recognize lead-related illness;
6. Encourages health practitioners to be trained to take occupational/environmental histories and to conduct a baseline blood lead if exposure is established;
7. Recommends funding for lead research on:
a) Techniques for assessing body lead burden;
b) Health effects of low-level exposure particularly on cardiovascular, reproductive, including effects on pregnant women and the fetus, neurologic and renal systems;
c) Control technologies and substitute materials.
8. Urges Congress to take steps to ensure that lead-using industries do not deny workers full employment rights and that no worker is required to submit to sterilization or fertility testing to forego procreation as a condition of employment.
