3. Hazard Identification

Emergency Overview: Clear, colourless to dark brown, odourless, dense, oily liquid. Will not burn. Can decompose at high temperatures forming toxic gases, such as sulphur oxides. Contact with combustible materials may cause fire. Highly reactive. Contact with many organic and inorganic chemicals may cause fire or explosion. Contact with metals liberates flammable hydrogen gas. Reacts violently with water. VERY TOXIC. May be fatal if inhaled or swallowed. CORROSIVE to the eyes, skin and respiratory tract. May cause blindness and permanent scarring. Causes lung injury -- effects may be delayed. Strong inorganic acid mists containing sulphuric acid are CARCINOGENIC. Risk of cancer depends on duration and level of exposure to the sulphuric acid mist. Do not get in eyes, on skin or on clothing. Do not Ingest. Do not breathe mist. Keep container closed. Use only with adequate ventilation. Wash thoroughly after handling.

Routes of Entry:

Inhalation: Sulphuric acid is not very volatile, and therefore workplace exposures are primarily to mists or aerosols. Sulphuric acid is corrosive and can cause severe irritation or corrosive damage if inhaled. The degree and severity of respiratory effects are influenced by factors such as the physical state and particle size of the aerosol, deposition site, concentration and humidity. Sulphuric acid can cause severe lung damage with a life-threatening accumulation of fluid (pulmonary edema).

Skin Contact: Sulphuric acid is corrosive and can cause severe irritation and burns, which may result in permanent scarring. Extensive acid burns can result in death. The severity of injury depends on the concentration of the Sulphuric acid solution and the duration of exposure. High mist or aerosol concentrations may cause redness, irritation and burns to the skin if contact is prolonged.

Eye Contact: Sulphuric acid is corrosive and can cause severe irritation (redness, swelling and pain) and permanent damage, including blindness. The severity of injury depends on the concentration of the Sulphuric acid solution and the duration of exposure. Sulphuric acid mists and aerosols are expected to be irritating.

Ingestion: Sulphuric acid is corrosive and will cause burns to the mouth, throat, esophagus and stomach if ingested. Symptoms may include difficulty swallowing, intense thirst, nausea, vomiting, diarrhea, and in severe cases, collapse and death. Small amounts of acid which may enter the lungs during ingestion or vomiting (aspiration) can cause serious lung injury and death.

Symptoms of Exposure: Skin irritation may be aggravated in individuals with existing skin lesions. Breathing of vapours may aggravate acute or chronic asthma and chronic pulmonary disease such as emphysema and bronchitis.

Page 2 4. First Aid Measures

Skin: Avoid direct contact. Immediately flush skin with running water for a minimum of 20 minutes. Start flushing while removing contaminated clothing. If irritation persists, repeat flushing. Obtain medical attention IMMEDIATELY. Do not transport victim unless the recommended flushing period is completed or flushing can be continued during transport. While the patient is being transported to a medical facility, apply compresses of iced water. If medical treatment must be delayed, immerse the effected area in iced water. Do not apply ointments unless directed by a physician. If immersion is not practical, compresses of iced water can be applied. Avoid freezing tissues. Discard heavily contaminated clothing arid shoes In a manner that limits further exposure. Otherwise, wash clothing separately before re-use.

Eyes: Avoid direct contact.Immediately flush eyes with running water for a minimum of 20 minutes. Hold eye lids open during flushing. If irritation persists, repeat flushing. Obtain medical attention IMMEDIATELY. Do not transport victim until the recommended flushing period is completed unless flushing can be continued during transport.

Inhalation: Avoid direct contact. Move victim to fresh air. Give artificial respiration ONLY if breathing has stopped. Do not use mouth-to-mouth method. If victim has ingested or inhaled the substance: give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Give Cardiopulmonary Resuscitation (CPR) if there is no pulse AND no breathing. Obtain medical attention IMMEDIATELY.

Ingestion: DO NOT INDUCE VOMITING. If victim Is alert and not convulsing, rinse mouth and give 1/2 to I glass of water to dilute material. If spontaneous vomiting occurs, have victim lean forward with head down to avoid breathing in of vomitus, rinse mouth and administer more water. IMMEDIATELY contact local poison control centre. Vomiting may need to be Induced but should be directed by a physician or a poison control centre. IMMEDIATELY transport victim to an emergency facility.

5. Fire-Fighting Measures

Conditions Of Flammability: Not combustible

Means To Extinguish: Sulfuric acid is not combustible. Use extinguishing agents suitable for the surrounding fire. Use water only to keep non-leaking, fire-exposed containers cool. If water is used, care should be taken, since it can generate heat and cause spattering if applied directly to sulfuric acid.

Hazardous Combustion Products : Toxic gases and vapours (e.g. sulphur dioxide, sulphur trioxide and acid mists) may be released when sulphuric acid decomposes.

Flash Point & Method: Not combustible Upper Flammability Limit: Not combustible Lower Flammability Limit: Not combustible Auto-Ignition Temperature: Not combustible Mechanical Impact Sensitivity : Not sensitive Static Discharge Sensitivity : Not sensitive

Page 3 6. Accidental Release Measures

Leak Or Spill Procedures : Small Spill and Leak: Cover with DRY earth, sand or other non-combustible absorbent material, which does not react with spilled chemical. Use clean tools to collect material and place it into loosely covered and labelled plastic containers for later disposal. Flush area with water.

Large Spill and Leak: Restrict access to area until completion of clean up. Ensure trained personnel conduct clean up. Ventilate area. Use appropriate Personal Protection Equipment. Prevent liquid from entering sewers or waterways. Stop or reduce teak only if safe to do so. Dike with inert material (sand, earth, etc.). Consider in situ neutralization with lime or soda ashand disposal. Place recovered materials into suitable corrosion resistant labelled containers. Ensure adequate decontamination of tools and equipment following clean up. Comply with Federal, Provincial/State and local regulations on reporting releases. Note: Contaminated absorbent material may pose the same hazards as the spilled product.

Waste Control Procedures : Will require to be transferred to a hazardous waste site. Consult appropriate Federal, State/Provincial and local regulatory authorities to determine disposal procedures.

7. Handling Storage

Handling Procedures And Equipment : Do not ingest. Do not breathe mist. Keep container closed. Use only with adequate ventilation. Wash thoroughly after handling. Use EXTREME care when diluting with water. Always add acid to water. CAUTION: Hydrogen, a highly flammable gas, can accumulate to explosive concentrations inside drums, or inside most types of metal containers or tanks upon storage. Carbon steel storage tanks must be vented,

Storage: If stored in non-reactive container keep container tightly closed. Metal and, specifically, carbon steel, storage tanks must be vented due to hydrogen release as noted above.

Page 4 8. Exposures Controls / Personal Protection

Protective Equipment: If engineering controls and work practices are not effective in controlling exposure to this material, then wear suitable personal protective equipment including approved respiratory protection. Have appropriate equipment available for use in emergencies such as spills or fire. If respiratory protection is required, institute a complete respiratory protection program including selection, fit testing, training, maintenance and inspection.

Respiratory Protection Guidelines : NIOSH RECOMMENDATIONS FOR Sulphuric acid CONCENTRATIONS IN AIR (22): 3 Up to 15 mg/m : SAR operated in a continuous-flow mode; or powered air-purifying respirator with acid gas cartridge(s) and a high-efficiency particulate filter. Full-facepiece chemical cartridge respirator with acid gas cartridge(s) and a high-efficiency particulate filter; or gas mask with acid gas canister and high-efficiency particulate filter; or full-facepiece SCBA; or full-facepiece SAR.

EMERGENCY OR PLANNED ENTRY INTO UNKNOWN CONCENTRATIONS OR IDLH CONDITIONS: Positive pressure, full-facepiece SCBA; or positive pressure, full-facepiece SAR with an auxiliary positive pressure SCBA.

ESCAPE: Gas mask with acid gas canister and high-efficiency particulate filter; or escape-type SCBA.

NOTE: Substance causes eye irritation or damage; eye protection needed. 3 NOTE: The IDLH concentration for Sulphuric acid is 15 mg/m . NOTE: The purpose of establishing an IDLH value is to ensure that the worker can escape from a given contaminated environment in the event of failure of the most protective respiratory protection equipment. In the event of failure of respiratory protection equipment every effort should be made to exit immediately.

The respirator use limitations specified by the approving agency and the manufacturer must be observed. Air-purifying respirators do not protect against oxygen-deficient atmospheres. Recommendations apply only to NIOSH approved respirators.

ABBREVIATIONS: SAR = supplied-air respirator; SCBA = self-contained breathing apparatus; IDLH = immediately dangerous to life or health.

Eye/Face Protection: Chemical safety goggles. A face shield may also be necessary when handling Sulphuric acid in an open system.

Skin Protection: Chemical protective gloves, coveralls, boots, and/or other resistant protective clothing. A chemical protective full-body encapsulating suit and respiratory protection may be required in some operations. Have a safety shower/eye-wash fountain readily available in the immediate work area.

Engineering Controls: Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapours below their respective occupational exposure limits. Ensure that eyewash stations and safety showers are proximate to the work-station location.

Reactivity Conditions: The product is stable. Will react violently with alkalis. The concentrated acid oxidizes, dehydrates, or sulfonates most organic compounds.

Incompatible Substances : Reactive with reducing agents, organic materials, alkalis, moisture, metals. Sulfuric acid reacts vigorously, violently or explosively with many organic and inorganic chemicals including water, acrylonitrile, alkali solutions, carbides, chlorates, fulminates, nitrates, perchlorates, permanganates, picrates, powdered metals, metal acetylides or carbides, epichlorohydrin, aniline, ethylenediamine, alcohols with strong hydrogen peroxide, chlorosulfonic acid, cyclopentadiene, hydrofluoric acid, nitromethane, 4-nitrotoluene, phosphorus (III) oxide, potassium, sodium, ethylene glycol, isoprene, styrene. Acetaldehyde and allyl chloride may polymerize violently in the presence of sulfuric acid. Hazardous gases, such as hydrogen cyanide, hydrogen sulfide and acetylene, are evolved on contact with chemicals such as cyanides, sulfides and carbides.

Page 6 Corrosivity to Metals: Sulfuric acid (10-100%) is corrosive to aluminum alloys at room temperature. The maximum attack occurs at 80% concentration. The rate of attack of less than 10% sulfuric acid is very low. The conventional austenitic grades of stainless steels, the 300 series, show good resistance in very dilute or highly concentrated sulfuric acid. Sulfuric acid in the intermediate concentration is more corrosive. Conventional ferritic grades, such as the 400 series are attacked by sulfuric acid. Sulfuric acid is corrosive to some austenitic stainless steels (e.g. type 304 (10-80%), 310 and 312 (10-85%), 316 and 321(10-80%). It also attacks type 17-4PH (50-100%) stainless steel. It is also corrosive to types 1010 and 1020 carbon steel (concentration 2-100%), cast iron (7-100%), 3% nickel cast iron, nickel (70-100%), nickel-base-alloys Inconel (60-100%) and Monel (70-100%), copper (all concentrations), and copper alloys, bronze (10-100%), silicon bronze (70-100%), aluminum bronze (65-100%), copper nickel 90-10 (5-100%), copper nickel 70-30 (80-100%), brass (10-100%), naval brass (70-100%), admiralty brass (10-100%), unalloyed titanium (all concentrations except very dilute solutions) and zirconium (65-100%).
