NIOSH Investigation Reveals No Long-Term Effects from Fiberglass at Steel Mill

August 1, 2013- NIOSH investigators have determined that fiberglass fibers at a steel mill are unlikely to cause long-term health issues, including respiratory disease, because the fibers’ large size and shape make them difficult to inhale into the lungs.

NIOSH investigators recently performed a health-hazard evaluation in response to employee concerns about skin irritation and potential respiratory problems from exposure to fiberglass fibers shedding from workers' cut-resistant sleeves. NIOSH staff found that while the fibers may cause temporary skin and upper respiratory irritation, no long-term issues are likely.

Other employees working in masonry reported numbness or pain in their hands and wrists from wearing the cut-resistant sleeves with thick gloves. NIOSH staff made recommendations, including:

• Provide employees who have concerns with alternative sleeves that offer the appropriate level of protection
• Provide masonry employees with thinner gloves with better grip and longer cuffs to reduce hand and wrist pain and numbness
• Train employees in proper care, useful life, and disposal of cut-resistant sleeves

During confidential interviews with employees, NIOSH also found that many were afraid to report occupational illnesses and injuries because they felt it would lead to disciplinary action. Investigators reported a “widespread” lack of trust in management among employees and suggested that an external consultant may help improve the workplace safety climate.

NIOSH also recommended that the steel mill use a labor-management health and safety committee to address such issues.
