Health and Safety
A study showed that there were no increases in risk of onset cancer for users or workers for the production of rock wool. The International Agency for Research on Cancer (IARC), has updated the previous Monograph and classification of 1987, concerning the health effects of various MMMF (Man-Made Mineral Fibers), excluding them from Group 2B (possibly carcinogenic).
Another important safety consideration when handling insulation is dust control. These recommended work practices will help you to use the products in a way that minimises transient itching of the skin.
How to reduce dust
1. Store the material to protect against damage, including humidity.
2. Unpack the material at the application site.
3. Cut the insulation on a flat surface. Use a sharp knife with serrated edge. Don’t use a saw. Unless you need to cut hard roof boards.
4. Open a door or open a window to ensure good ventilation.
5. Organize your workplace in a manner that makes mounting and fixing easy.
6. Cover open ventilation ducts to reduce particulate in the ducts.
7. In confined spaces with poor ventilation use protective goggles and a dust mask. Gloves and loose fitting, longsleeved, longlegged work clothes advised.
8. Keep your workplace clean. Prevent whirling dust. Use a vacuum cleaner, not a broom.
9. Don’t rub. Wash in cold water. Change clothes and wash on completing work.
