Industrial Health and Safety Criteria for Abrasive Blast Cleaning Operations.

摘要

The purpose of the study was to assess and/or evaluate the existing standards and safety and health conditions in a broad representative scope of abrasive blast cleaning operations within various U.S. industries. The goal of the assessment was to recommend changes or additions to enhance ventilation,safety,and health criteria and to substantially improve personal protective equipment for abrasive blast cleaning operators and other workers who must work in the pressure blast cleaning area. Within both federal and private industrial facilities,surveys metered noise level exposure to the blast cleaning equipment operator and nearby workers. Ventilation change rates within blast cleaning rooms were monitored and dust counts taken at various radii from point of operation up to 100feet from the operator. General safety and health conditions for operator and nearby workers were evaluated and documented. The present status of personal protective equipment was evaluated with respect to their personal protective effectiveness.
