CAS Registry No.: 7664-93-9Other Names: Battery acid, sulphuric acidMain Uses: Manufacture of fertilizers and other chemicals; petroleum refining; battery component.Appearance: Clear colourless oily liquid. Yellow to dark brown in colour when impure.Odour: Odourless

Specific Hazards Arising from the Chemical: Contact with water causes violent frothing and spattering. Reacts with metals to produce highly flammable hydrogen gas. Closed containers may rupture violently when heated releasing contents. In a fire, the following hazardous materials may be generated: corrosive sulfur oxides.

Engineering Controls: Use a local exhaust ventilation and enclosure, if necessary, to control amount in the air. Use stringent control measures such as process enclosure to prevent product release into the workplace. Use a corrosion-resistant exhaust ventilation system separate from other ventilation systems.

Storage: Store in an area that is: cool, dry, out of direct sunlight and away from heat and ignition sources, separate from incompatible materials. Avoid bulk storage indoors. Regularly inspect for physical changes or signs of crystallization, damage or leaks.

Please note that this classification was retrieved from the CNESST site on February 22, 2023and was established by CNESST personnel to the best of their knowledge based on data obtained from scientific literature and it incorporates the criteria contained in the Hazardous Products Regulations (SOR/2015-17). It does not replace the supplier’s classification which can be found on its Safety Data Sheet.

Up to 15 mg/m3: (APF = 25) Any supplied-air respirator operated in a continuous-flow mode*; or Any powered, air-purifying respirator with acid gas cartridge(s) in combination with a high-efficiency particulate filter*.(APF = 50) Any chemical cartridge respirator with a full facepiece and acid gas cartridge(s) in combination with an N100, R100, or P100 filter; or Any air-purifying, full-facepiece respirator (gas mask) with a chin-style, front- or back-mounted acid gas canister having an N100, R100, or P100 filter; or Any self-contained breathing apparatus with a full facepiece; or Any supplied-air respirator with a full facepiece.

Recommendations apply only to National Institute for Occupational Safety and Health (NIOSH) approved respirators. Refer to the NIOSH Pocket Guide to Chemical Hazards for more information.

Exposure Guideline Comments: TLV® = Threshold Limit Value. TWA = Time-Weighted Average. T = Thoracic particulate matter. Sulfuric acid itself has not been evaluated for carcinogenicity. (M) ACGIH has evaluated strong inorganic mists containing sulfuric acid. This classification is A2 - Suspected human carcinogen.

Guide signs inform, advise and direct road users about the route they are following and are used in permanent traffic management scenarios. They give instructions and distances to destinations, identify points of geographical or historical interest, cyclist information and tourist facilities and/or attractions.

Skin Contact: Avoid direct contact. Wear chemical protective clothing if necessary. Quickly take off contaminated clothing, shoes and leather goods (e.g. watchbands, belts). Quickly and gently blot or brush away excess chemical. Immediately flush with gently flowing water for at least 30 minutes. DO NOT INTERRUPT FLUSHING. If it can be done safely, continue flushing during transport to hospital. Get medical attention as soon as possible. Treatment is urgently required. Transport to a hospital. Double bag, seal, label and leave contaminated clothing, shoes, and leather goods at the scene for safe disposal.

NOTE: In many (but not all) Canadian jurisdictions, the exposure limits are similar to the ACGIH® TLVs®. Since legislation varies by jurisdiction, contact your local jurisdiction for exact details. A list is available in the OSH Answers on Canadian Governmental Occupational Health & Safety Departments.

Emergency Overview: Clear colourless oily liquid. Odourless. Will not burn. VERY TOXIC. Fatal if inhaled. Can form very hazardous decomposition products. Highly Reactive. Incompatible with many common chemicals. Reacts violently with water. CORROSIVE. Causes severe skin burns and eye damage. Strong inorganic acid mists containing sulfuric acid are carcinogenic.

This category includes our most popular guide road signs, however we can also produce all other signage listed in the Australian Standard. In addition, if you require a design that is not in our catalogue, we can also manufacture customised road signs on request. Please contact our friendly team to discuss your requirements.

Handling: Avoid generating vapours or mists. Immediately report leaks, spills, or failures of the safety equipment (e.g., ventilation system). Prevent unintentional contact with incompatible chemicals. Never add water to a corrosive. Always add corrosives slowly to COLD water. If the product is transferred to another container, ensure the new container is suitable for the product. Never reuse empty containers, even if they appear to be clean.

Guide signs are manufactured in metal or aluminium in various sizes as dictated by the Australian Standard. Guide signs feature either text or symbolic pictograms, or in some instances a combination of both.

According to the Commission des normes, de l'équité, de la santé et de la sécurité du travail (CNESST), sulfuric acid can be classified as:

Eye Contact: Avoid direct contact. Wear chemical protective gloves if necessary. Quickly and gently blot or brush chemical off the face. Immediately flush the contaminated eye(s) with gently flowing water for at least 30 minutes, occasionally lifting the upper and lower eyelids. If a contact lens is present, DO NOT delay flushing or attempt to remove the lens. Neutral solution may be used as soon as it is available. DO NOT INTERRUPT FLUSHING. If necessary, continue flushing during transport to hospital. Take care not to rinse contaminated water into the unaffected eye or onto the face. Get medical attention as soon as possible. Treatment is urgently required. Transport to a hospital.

Skin Protection: Wear chemical protective clothing e.g. gloves, aprons, boots. Suitable materials (sulfuric acid 30-70%) include:  butyl rubber, natural rubber, neoprene rubber, polyvinyl chloride (PVC), Viton®, Viton®/butyl rubber, AlphaTec® (02-100, 4000, EVO, VPS), Kemblok®,  Silver Shield® - PE/EVAL/PE, Saranex®™, Chemprotex® 300, ChemMAX® 3, Tychem®  6000.

This 40km speed sign is Class 1 retroreflective and designed and manufactured to meet the relevant Australian Standards.

First Aid Comments: Some of the first aid procedures recommended here require advanced first aid training. All first aid procedures should be periodically reviewed by a medical professional familiar with the chemical and its conditions of use in the workplace.

Personal Precautions: Evacuate the area immediately. Isolate the hazard area. Keep out unnecessary and unprotected personnel. Do not touch damaged containers or spilled product unless wearing appropriate protective equipment. Remove or isolate incompatible materials as well as other hazardous materials.

Inhalation: Take precautions to ensure your own safety before attempting rescue (e.g. wear appropriate protective equipment). Move victim to fresh air. Keep at rest in a position comfortable for breathing. If breathing is difficult, trained personnel should administer emergency oxygen. If breathing has stopped, trained personnel should begin artificial respiration (AR). DO NOT allow victim to move about unnecessarily. Symptoms of pulmonary edema may be delayed. Get medical attention as soon as possible. Treatment is urgently required. Transport to a hospital.

Methods for Containment and Clean-up: Small spills or leaks: contain and soak up spill with absorbent that does not react with spilled product. Place used absorbent into suitable, covered, labelled containers for disposal. Large spills or leaks: contain and soak up spill with absorbent that does not react with spilled product. Dike spilled product to prevent runoff. Remove or recover liquid using pumps or vacuum equipment. Place used absorbent into suitable, covered, labelled containers for disposal. Store recovered product in suitable containers that are: corrosion-resistant. Contaminated absorbent poses the same hazard as the spilled product.
