11. TOXICOLOGICAL INFORMATION

Human Data

There is no information on toxicokinetics, metabolism and distribution.

There have been reports of irritation and burns to mucus membranes of the eyes and respiratory tract

upon acute exposure to dusts in excess of the recommended limits.

Chronic exposure to crystalline silica (a naturally occurring contaminant) in the respirable size has been

shown to cause silicosis, a debilitating lung disease. In addition, the International Agency for Research on

Cancer (IARC) classifies crystalline silica inhaled in the form of quartz or cristobalite from occupational

sources as carcinogenic to humans, Group 1. The National Toxicology Program (NTP) classifies

respirable crystalline silica as a substance which may be reasonably anticipated to be a carcinogen.

OSHA does not regulate crystalline silica as a human carcinogen. Industrial hygiene monitoring to date

has not identified any detectable respirable crystalline silica in dust sampling conducted during gypsum

panel installation utilizing recommended procedures.
