This product maycontain small amounts of Hydrogen sulphide which may accumulate inconfined spaces. Inhalation of Hydrogen sulphide may cause loss ofsense of smell, major irritation of the respiratory tract, headache, nausea,vomiting, dizziness, and fluid buildup in the lungs (pulmonary edema),which can be fatal. At 300 ppm unconsciousness may occur after 20minutes. From 300 to 500 ppm, death can occur within 1 to 4 hours ofcontinuous exposure. At 500 ppm the respiratory system is paralyzed, thevictim collapses almost instantaneously, and death can occur afterexposure of only 30 to 60 minutes. Above 500 ppm Hydrogen sulphidemay cause immediate loss of consciousness; death is rapid, and possiblyimmediate. Inhalation of Sulphur dioxide at concentrations ofapproximately 6 ppm will result in eye, nose and throat irritation. Severeoverexposure may result in death from systemic acidosis, pulmonaryedema or from respiratory arrest. Prolonged or repeated inhalation ofsulphur dioxide may cause impaired lung function, bronchitis, cough andfatigue.Eye Contact:If in eyes: Rinse cautiously with water for at least 20 minutes. Removecontact lenses, if present and easy to do. Continue rinsing. Call a poisoncenter or doctor if you feel unwell.Acute and delayed symptoms and effects: May cause eye irritation.Signs/symptoms may include redness, swelling, pain, tearing, and blurredor hazy vision.Skin Contact:If on skin: Wash with plenty of soap and water. If skin irritation occurs: Getmedical advice/attention. Take off contaminated clothing and wash itbefore reuse.Acute and delayed symptoms and effects: Causes skin irritation.Signs/symptoms may include localized redness, swelling, and itching.Ingestion:If swallowed: Call a poison center or doctor if you feel unwell. If vomitingoccurs naturally, have victim lean forward to reduce the risk of aspiration.Do NOT induce vomiting unless directed to do so by medical personnel.Never give anything by mouth to an unconscious person.Page 2 of 11Deerfoot Consulting Inc.

Signs/symptoms may include abdominal pain, stomach upset,nausea, vomiting and diarrhea. Sulphur may be converted into Hydrogensulphide in the intestine.General Advice:In case of accident or if you feel unwell, seek medical advice immediately(show the label or SDS where possible).Note to Physicians:Symptoms may not appear immediately. For inhalation of HydrogenSulphide, consider oxygen.Section 5: FIRE-FIGHTING MEASURESFLAMMABILITY AND EXPLOSION INFORMATIONCombusts slowly in air with pale flame which may be hard to see, especially in low humidityatmospheres. Flammable solid in powder form. May form combustible dust concentrations in air.Avoid contact with hot exhaust pipes and spark sources of ignition e.g. steel tracked vehicles.Does not meet criteria for classification as Class 4.1 Flammable Solids under IMOT/TDGRegulations. When heated, this material may evolve toxic and flammable Hydrogen sulphide.Sensitivity to Mechanical Impact:Sensitivity to Static Discharge:MEANS OF EXTINCTIONSuitable Extinguishing Media:This material is not sensitive to mechanical impact.In the form of dust, this material is sensitive to staticdischarge and may form explosive mixtures with air. Thismaterial is sensitive to static discharge at temperatures at orabove the flash point.Small Fire: Dry chemical, CO2, sand, earth, water spray orregular foam. Flood with water. Apply extinguishing mediacarefully to avoid creating airborne dust.Large Fire: Water spray, fog or regular foam. Movecontainers from fire area if you can do it without risk.Unsuitable Extinguishing Media:Not available.Products of Combustion:Oxides of sulphur.Protection of Firefighters:Fire may produce irritating and/or toxic gases. Contact maycause burns to skin and eyes. Runoff from fire control maycause pollution. Hydrogen sulphide is heavier than air andmay collect in low lying areas and confined spaces. Wearpositive pressure self-contained breathing apparatus (SCBA).Structural firefighters' protective clothing will only providelimited protection. Avoid generating dust; fine dust dispersedin air in sufficient concentrations, and in the presence of anignition source is a potential dust explosion hazard.Section 6: ACCIDENTAL RELEASE MEASURESEmergency Procedures:Keep unauthorized personnel away. Stay upwind. Keep out of lowareas. Ventilate closed spaces before entering. ELIMINATE allignition sources (no smoking, flares, sparks or flames inimmediate area).Page 3 of 11Deerfoot Consulting Inc.

Sulphur, SolidSAFETY DATA SHEET / MATERIAL SAFETY DATA SHEETDate of Preparation: December 8, 2014Personal Precautions:Do not touch or walk through spilled material. Use personalprotection recommended in Section 8. Keep away from heat,sparks and flame. Keep container closed (and grounded). Preventdust accumulation (to minimize explosion hazard). Don full-face,positive pressure, self-contained breathing apparatus.Environmental Precautions:Prevent entry into waterways, sewers, basements or confinedareas.Methods for Containment:Do not flush to sewer or allow to enter waterways.Methods for Clean-Up:Use explosion-proof equipment. Dust can be a fire or explosionhazard. Sweep up and shovel into suitable containers for disposal.Cleaning methods (e.g. compressed air) which can generatepotentially combustible dust clouds should not be used.Other Information:See Section 13 for disposal considerations.Section 7: HANDLING AND STORAGEHandling:Minimize dust generation and accumulation. Airborne dusts are potentially explosive. Do notswallow. Keep away from heat, sparks, open flames, and hot surfaces. – No smoking. Washthoroughly after handling. See Section 8 for information on Personal Protective Equipment.Storage:Routine housekeeping should be instituted to ensure that dusts do not accumulate on surfaces.Store away from incompatible materials.
