EH&S evaluates workplaces for possible airborne hazards and recommends ways to reduce these hazards when found. When appropriate, EH&S will fit campus workers with respirators and provide annual training on their proper use. This program is administered in cooperation with University Health Services. UHS evaluates a person's ability to safely wear a respirator prior to a respirator being issued. For more information contact EH&S at ehs@berkeley.edu.
