Phosphorus vapor exposure in phosphorus using plants

W R King, J E Peterson

    American Industrial Hygiene Association Journal
    |November 1, 1978
    PubMed
    Summary

    Operator exposure to phosphorus was assessed in five plants. Monitoring confirmed no worker phosphorus levels exceeded the 0.1 mg/M3 threshold limit value (TLV), indicating safe working conditions.

    Area of Science:

    • Industrial Hygiene
    • Occupational Health
    • Environmental Monitoring

    Background:

    • Phosphorus handling in industrial settings presents potential occupational health risks.
    • Understanding operator exposure levels is crucial for maintaining workplace safety standards.

    Purpose of the Study:

    • To document and assess operator exposure to phosphorus in five FMC plants.
    • To compare measured exposure levels against established threshold limit values (TLVs).

    Main Methods:

    • Primarily utilized area sampling to measure phosphorus vapors.
    • Supplemented with personal sampling in areas with significant phosphorus vapor detection.
    • Calculated eight-hour time-weighted-average (TWA) exposure levels for operators.

    Main Results:

    • Phosphorus exposure levels were documented across five industrial plants.
    • No monitored worker, including maintenance staff, exceeded the TLV of 0.1 mg/M3.
    • Area measurements were used to estimate operator exposure in phosphorus burning plants.

    Conclusions:

    • Current operational practices effectively control phosphorus exposure below regulatory limits.
    • The study confirms the safety of operators and maintenance workers regarding phosphorus vapor exposure.
    • Findings support the adequacy of existing monitoring protocols for phosphorus handling facilities.
