OSHA Proposes New Silica Exposure Rule
Source: Sensear | 27 September 2013The Occupational Safety and Health Administration (OSHA) in the United States recently released a proposed rule, the Notice of Proposed Rulemaking (NPRM) for Occupational Exposure to Respirable Crystalline Silica.
OSHA proposes reducing the permissible exposure limits for respirable crystalline silica to 50 μg/m3 or below. Among the suggested solutions are wearing respiratory equipment to protect the worker from exposure. OSHA has taken into consideration the difficulty this requirement brings to effective communications within certain industries. An excerpt from the proposed rule states: “Safety problems created by respirators that limit vision and communication must also be considered. In some difficult or dangerous jobs, effective vision or communication is vital. Voice transmission through a respirator can be difficult and fatiguing.”
