Call a physician if irritation persists. Skin Contact: Remove contaminated clothing and wash affected area with soap and water. Call a physician if irritation persists. Wash contaminated clothing prior to re-use. Inhalation: Remove person to fresh air. Keep person calm. If not breathing, give artificial respiration. If breathing is difficult give oxygen. Call a physician. Ingestion: If swallowed, DO NOT induce vomiting. Get medical attention immediately. Note to Physicians: None Section 5: Fire-Fighting Measures Flammable Properties: As defined by OSHA, this product is nonflammable. Flash Point: None (TCC) Upper Explosive Limit: None Autoignition Temperature: None Lower Explosive Limit: None Suitable Extinguishing Media: This material will not burn. Use extinguishing media appropriate for the surrounding fire. Products of Combustion: NA Protection of Fire-Fighters: Firefighters should wear self-contained, NIOSH-approved breathing apparatus for protection against suffocation and possible toxic decomposition products. Proper eye and skin protection should be provided. Use water spray to keep fire-exposed containers cool and to knock down vapors which may result from product decomposition. Section 6: Accidental Release Measures Personal Precautions: Use personal protection recommended in Section 8. Environmental Precautions: Take precautions to prevent contamination of ground and surface waters. Do not flush into sewers or storm drains. This product is harmful to aquatic life. Product Name: K&W? Permanent Metallic? Product Number (s): Block Seal Page 3 of 6 Methods for Containment & Clean-up: Dike area to contain spill. Ventilate the area with fresh air. If in confined space or limited air circulation area, clean-up workers should wear appropriate respiratory protection. Recover or absorb spilled material using an absorbent designed for chemical spills. Place used absorbents into proper waste containers. Section 7: Handling and Storage Handling Procedures: Avoid contact with eyes, skin and clothing. Keep container closed when not in use. Properly clean any spilled residue with a wet cloth. Storage Procedures: Store in a cool dry area out of direct sunlight. Store in closed container. Do not store near acids.

Not Established (c) ? ceiling (s) ? skin (v) ? vacated * Exposure values apply to dust or respirable fraction. These values would not apply to the liquid mixture product. These would only apply to this product if it were dried to a powder or residue. Engineering Controls: Area should have ventilation to provide fresh air. Use local exhaust to prevent accumulation of vapors. Use mechanical means if necessary to maintain vapor levels below the exposure guidelines. If working in a confined space, follow applicable OSHA regulations Respiratory Protection: None required for normal work where adequate ventilation is provided. Use a self-contained breathing apparatus in confined spaces and for emergencies. Eye/face Protection: For normal conditions, wear safety glasses. Where there is reasonable probability of liquid contact, wear splash-proof goggles. Skin Protection: Use protective gloves such as nitrile or neoprene. Also , use full protective clothing if there is prolonged or repeated contact of liquid with skin.
