Dear Mr. Hays:

Thank you for your letter of May 30, regarding the warning labels of Owens-Corning Fiberglass products under the Occupational Safety and Health Administration's (OSHA) Hazard Communication Standard, 29 CFR 1910.1200. Your letter forwarded for our review a copy of a "new" label intended for use by Owens-Corning for products that contain fiberglass wool. The label you forwarded contains the following hazard warning: "Contains fiberglass wool. Possible cancer hazard. To avoid this possible cancer hazard, minimize breathing fiberglass wool dust." In addition, the warning: "May cause irritation to skin, eyes and respiratory tract" also appears on the label. This specific language serves to provide employees with appropriate hazard warning information for this particular product. The label appears to meet the intent of the HCS and would therefore be in compliance with the requirements of OSHA's Hazard Communication Standard. We might add that OSHA has no enforcement action pending against your company in this matter. We hope this information is helpful to you and appreciate your patience for the delay of this response. Please feel free to contact us again if we can be of further assistance.

Protect your lungs from respiratory hazards with supplied air respirator system like this one from Safety Emporium.

Sincerely,

Patricia K. Clark, Director
Directorate of Compliance Programs
