Eye Contact: If in eyes: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Skin Contact: Rinse skin with water/shower. Ingestion: If swallowed: Rinse mouth. 4(b) Most Important Symptoms/Effects, Acute and Delayed (Chronic): Acute effects: Inhalation: Excessive exposure to high concentrations of dust may cause irritation to the mucous membranes of the upper respiratory tract. Page 1 of 9 Steelmaking Slags Code No.: 9934 Rev. 05/25/2015 Section 4 – First-aid Measures (continued) Eye: Excessive exposure to high concentrations of dust may cause irritation to the eyes. Skin: Skin contact with dusts may cause irritation or dermatitis. Ingestion: Ingestion of dust may cause nausea and/or vomiting. Chronic Effects: Individuals with chronic respiratory disorders (i.e., asthma, chronic bronchitis, emphysema, etc.) may be adversely affected by any airborne particulate matter exposure. Persons with pre-existing skin disorders may be more susceptible to dermatitis. 4(c) Immediate Medical Attention and Special Treatment: Treat symptomatically. Section 5 – Fire-fighting Measures 5(a) Suitable (and Unsuitable) Extinguishing Media: Use extinguishers appropriate for surrounding materials. 5(b) Specific Hazards Arising from the Chemical: Not applicable for solid product. 5(c) Special Protective Equipment and Precautions for Fire-fighters: Self-contained NIOSH approved respiratory protection and full protective clothing should be worn when fumes and/or smoke from fire are present. Heat and flames cause emittance of acrid smoke and fumes. Do not release runoff from fire control methods to sewers or waterways. Firefighters should wear full face-piece self-contained breathing apparatus and chemical protective clothing with thermal protection. Direct water stream will scatter and spread flames and, therefore, should not be used. Section 6 - Accidental Release Measures 6(a) Personal Precautions, Protective Equipment and Emergency Procedures: For spills involving finely divided particles, clean-up personnel should be protected against contact with eyes and skin. If material is in a dry state, avoid inhalation of dust. Personnel should be protected against contact with eyes and skin. Fine, dry material should be removed by vacuuming or wet sweeping methods to prevent spreading of dust. Avoid using compressed air. Do not release into sewers or waterways. 6(b) Methods and Materials for Containment and Clean Up: Collect material in appropriate, labeled containers for recovery or disposal in accordance with Federal, Provincial/State, and Local regulations. Follow applicable OSHA regulations (29 CFR 1910.120) and all other pertinent Provincial/State and Federal requirements. Section 7 - Handling and Storage 7(a) Precautions for safe handling: Avoid contact with skin and eyes. Avoid inhalation of dust. Avoid dust generation during handling. Do not shake, dry sweep or blow dust. Launder contaminated clothing before re-use.. 7(b) Conditions for safe storage, including any incompatibilities: Keep in a cool and well ventilated area. Protect stored material from getting wet. Store away from incompatibles.. Section 8 - Exposure Controls / Personal Protection 8(a) Occupational Exposure Limits (OELs): The following exposure limits are offered as reference, for an experience industrial hygienist to review.

OSHA PELs (Permissible Exposure Limits) are 8-hour TWA (time-weighted average) concentrations unless otherwise noted. A (“C”) designation denotes a ceiling limit, which should not be exceeded during any part of the working exposure unless otherwise noted. An Action level (AL) is used by OSHA and NIOSH to express a health or physical hazard. They indicate the level of a harmful or toxic substance/activity, which requires medical surveillance, increased industrial hygiene monitoring, or biological monitoring. Action Levels are generally set at one half of the PEL but the actual level may vary from standard to standard. The intent is to identify a level at which the vast majority of randomly sampled exposures will be below the PEL. 2. Threshold Limit Values (TLV) established by the American Conference of Governmental Industrial Hygienists (ACGIH) are 8-hour TWA concentrations unless otherwise noted. ACGIH TLVs are for guideline purposes only and as such are not legal, regulatory limits for compliance purposes. A Short Term Exposure Limit (STEL) is defined as the maximum concentration to which workers can be exposed for a short period of time (15 minutes) for only four times throughout the day with at least one hour between exposures. 3. The National Institute for Occupational Safety and Health Recommended Exposure Limits (NIOSH-REL) - Compendium of Policy and Statements. NIOSH, Cincinnati, OH (1992). NIOSH is the federal agency designated to conduct research relative to occupational safety and health. As is the case with ACGIH TLVs, NIOSH RELs are for guideline purposes only and as such are not legal, regulatory limits for compliance purposes. 4. Ontario Ministry of Labour. Employers are required under section 4 of Regulation 833, Control of Exposure to Biological or Chemical Agents (the “Regulation”), to limit the exposure of workers to specified hazardous biological or chemical agents in accordance with the values set out in the “Ontario Table” (which is Table 1 in the Regulation) or, if the agent is not listed in the Ontario Table, the ACGIH Table that is incorporated by reference in the Regulation.. 5. Inhalable fraction. The concentration of inhalable particulate for the application of this TLV is to be determined from the fraction passing a size-selector with the characteristics defined in the ACGIH 2013 TLVs ® and BEIs ® (Biological Exposure Indices) Appendix D, paragraph A.
