Cautions
Glass fibers are contained within GreenGlass gypsum sheathing and in the glass facers. Handling may cause skin irritation. Cutting and handling may release glass fibers. Do not use a power saw. Avoid inhalation of these fibers as they may cause respiratory irritation or even aggravated medical conditions.
- Skin: If skin contact causes irritation, wash the area with soap and water.
- Eyes: If contact with eyes, flush the eye with clean water for 15 minutes.
- Lungs: Avoid any inhalation of fibers. If unintended inhalation occurs, move to an area of fresh air.
Handling and Hygiene
Care should be used in handling GreenGlass gypsum sheathing to ensure worker comfort and safety. Below are some handling guidelines and safety requirements:
- Avoid breathing dust-glass fibers by using a NIOSH-approved dust mask when cutting or sanding.
- Gloves and loose fitting long sleeved clothing should be worn to avoid contact of the GreenGlass with bare skin.
- Eye protection with side protection should be worn. Use either safety glasses with side shields or goggles.
- Skin should be washed after contact with GreenGlass. Wash exposed skin with soap and water.
- Clothing may entangle glass fibers. Clothing which has glass fibers entangled should be washed separately from other clothing.
