Class F Fly Ash

SECTION 2: Hazards identification

WARNING Irritant: Causes eye, skin and inhalation irritation Toxic – Harmful by inhalation. Eye Protection Respiratory (Contains crystalline silica) Protection Use proper engineering controls, work practicies, and personal protective equipment to prevent Gloves Boots exposure to wet or dry product READ SDS FOR DETAILS Emergency Overview: Ash is a solid, grey/black or brown/tan, odorless powder which may contain solidified messes. It is not combustible or explosive. A single, short-term exposure to the dry powder presents little or no hazard.

Potential health effects

Eye Contact: Airborne dust may cause immediate or delayed irritation or inflammation. Eye contact with large amounts of dry powder or with wet ash can cause moderate eye irritation. Eye exposures require immediate first aid to prevent significant damage to the eye. Skin Contact: Ash may cause dry skin, discomfort, and irritation. Inhalation (acute): Breathing dust may cause nose, throat, or lung irritation, including choking, depending on the degree of exposure. Ash may contain trace amounts of ammonia or ammonia bisulfate. Contact with water or moisture can cause the ammonia to be released from ash into the air. Inhalation of ammonia can cause coughing and irritation or burns to the nose, throat and lungs. These effects depend on the concentration of ammonia inhaled. Inhalation (chronic): Risk of injury depends on duration and level of exposure. SDS Class F Fly Ash Cranesville Block Co. 1 Silicosis: This product contains crystalline silica. Prolonged or repeated inhalation or respirable crystalline silica from this product can cause silicosis, a seriously disabling and fatal lung disease. See Note to Physicians in Section 4 for further information. Carcinogenicity: Ash is not listed as a carcinogen by IARC or NTP; however, ash contains trace amounts of crystalline silica which is classified by IARC and NTP as known human carcinogen. Autoimmune Disease: Some studies show that exposure to respirable crystalline silica (without silicosis) or that the disease silicosis may be associated with he increased incidence of several autoimmune disorders such as scleroderma (thickening of the skin), systemic lupus erythematosus, rheumatoid arthritis and diseases affecting the kidneys. Tuberculosis: Silicosis increases the effect of tuberculosis. Renal Disease: Some studies show an increased incidence of chronic kidney disease and end- stage renal disease in workers exposed to respirable crystalline silica. Ingestion: Do not ingest ash. Although ingestion of small quantities of ash is not known to be harmful, large quantities can cause distress to the digestive tract.

Medical Conditions Generally Aggravated by Exposure

Individuals with lung disease (e.g. bronchitis, emphysema, COPD, pulmonary disease) can be aggravated by exposure.
