Confined spaces--a case for ventilation.

R P Garrison, D R McFee

    American Industrial Hygiene Association Journal
    |November 1, 1986
    PubMed
    Summary
    This summary is machine-generated.

    Ventilating confined spaces before and during entry can prevent many deaths and injuries. Enhanced guidance and research are needed to improve ventilation strategies and reduce accidents.

    Area of Science:

    • Occupational Safety and Health
    • Environmental Engineering

    Background:

    • Confined space incidents frequently result in fatalities and injuries.
    • Existing safety standards often lack mandatory ventilation requirements and specific guidance.
    • The critical role of ventilation in mitigating atmospheric hazards is underestimated.

    Purpose of the Study:

    • To highlight the necessity of ventilation in confined spaces.
    • To identify the gaps in current standards and guidance regarding confined space ventilation.
    • To advocate for increased research and information dissemination on effective ventilation strategies.

    Main Methods:

    • Review of current standards and guidelines for confined space entry.
    • Analysis of the effectiveness of mechanical versus natural ventilation.

  • Identification of the need for further research and practical examples.

    • Main Results:

    • Mechanical ventilation is a reliable engineering control for adverse atmospheric conditions.
    • Natural ventilation is insufficient as a primary control method.
    • There is a significant lack of specific information on designing and implementing confined space ventilation strategies.

    Conclusions:

    • Ventilation is a preventable measure for many confined space hazards.
    • Current regulations and practices inadequately address confined space ventilation.
    • Further research, policy development, and information sharing are crucial to enhance safety.
