OSHA Silica Standard Pocket Guide

Supervisors Overview What Site Supervisors are responsible for:

• Obtaining a copy of the OSHA Table 1 tool which will allow for ease of safety control instructions for those workers with potential exposures.

• Ensuring that all the tools, equipment, PPE and materials (including water) necessary to implement the ECP is available (and in good working order) prior to allowing work activities to commence.

• Ensuring that all workers (under the supervisor’s direction and control) have received the necessary education and training applicable to perform tasks with potential exposures to respirable crystalline silica.

• Ensuring that workers adhere to the project/task specific ECP, OSHA Table 1 and safety plans, including PPE and personal hygiene practices (i.e. including be clean shaven where the respirator seals to the user’s face where applicable) requirements.

• Coordinating work activities with the Contractors as required, and/or otherwise implementing the controls necessary to protect others.

• If the site conditions or work performed by another contractor causes exposure to your and or your employees, remove from the immediate area.
