Composition comments

All concentrations are in percent by weight unless ingredient is a gas.

Results of an industrial hygiene study found no airborne respirable crystalline silica in the

breathing zones of workers during the normal activities associated with the use of this product.

However, job site air monitoring should be conducted when permissible exposure limits may be

exceeded.

4. First-aid measures

Inhalation

Dust irritates the respiratory system, and may cause coughing and difficulties in breathing. Move

injured person into fresh air and keep person calm under observation. Get medical attention if
