Background
Lead has long industrial history Roman Empire
Lead has regulatory history in USA Lead-Based Paint Poisoning Prevention Act of
1971 Leaded automobile gasoline reduction in 1973;
final complete phase-out in 1996 New Jersey has a long industrial history that
has changed greatly over the last decade.

Methodology Utilized Chemical Handling Survey validated in 2003 – 2004 and
reported by Lefkowitz et al. Questions in five broad descriptive categories.
basic facility information; operational characteristics; material handling; lead usage; engineering and personal exposure control measures descriptions.
Survey mailed to 104 companies in ABLES registry. 45 companies responded, 43% response rate.
Conducted on-site visits for 16 of the survey respondents, which is 35% of sample
Survey responses from companies with employees in Adult Blood Registry ≥25 μg/dL were analyzed.

Methodology
Survey responses were reviewed by Industrial Hygienist and judgment was made regarding potential for inhalation and incidental ingestion among reported job titles.
Survey responses were tabulated and described in simple histograms.
OSHA Integrated Management and Inspection System (IMIS) was searched to determine inspection and regulatory compliance history of survey respondents.

OSHA Inspection History of Survey Respondents
Utilized OSHA IMIS database matched on name or address; partial matches
acceptable Survey respondents
53% (n=24) have never been inspected by OSHA 29% (n=13)have been cited for violating an OSHA
standard 18% (n=8) have been cited by OSHA specifically for
violations of the lead standard

Conclusions
Lead usage & lead exposure is still widespread. Many companies with employees that have elevated
blood lead values (≥25 ug/dL) do not utilize basic hygiene practices.
The OSHA lead standard would be strengthened if blood lead screening was used in conjunction with air sampling to determine which provisions of the standard are required for full compliance.
The OSHA referral process for State based surveillance programs for lead (ABLES) are crucial for effective targeting of OSHA inspections.
