1 BUTANOL PETRONAS Disclaimer: The purpose of this Global Product Strategy (GPS) Safety Summary is to provide interested stakeholders an overview of the above specified chemical substance. This product summary contains general information on the potential hazards, exposure scenarios, safe handling and risk management and it is not intended to provide guidelines to manage incidents or emergencies by response professionals. Detailed health and safety information is included on the respective Safety Data Sheet (SDS). The content of this document is based on the information available as of the date of preparation of the. Any intended purpose, either implicit or explicit, which may be related to the information provided is not under any warranty. PETRONAS assumes no obligation or liability whatsoever resulting from use of or reliance on the information given.

2 GENERAL STATEMENT (CAS No ) is a clear liquid at room temperature with an alcohol-like odour. It is partly soluble in water, but mixes easily with most of the common organic solvents. is a flammable liquid. The substance should be kept away from sources of ignition including static discharge and the contact of with oxidizing materials should be avoided. Synonyms for include butyl alcohol, 1-butanol, n-butanol and propylcarbinol. USES AND APPLICATIONS is mostly used as an industrial intermediate to make other chemicals, as a solvent in chemical and industrial process, and as an ingredient in formulated products such as cosmetics. Some of the applications of include: As a solvent in curable lacquers and cross linked finishes As a swelling agent in textiles As a fuel additive and component of brake fluid in automotive As a floatation agent PHYSICAL AND CHEMICAL PROPERTIES OF BUTANOL Properties Structural formula Value Physical state Melting point/freezing point Clear liquid -89 C Boiling point 118 C Odour Water solubility Alcohol-like 7.45 g/l (25 C) PETRONAS CHEMICALS GROUP BERHAD 1

3 HUMAN HEALTH SAFETY OF BUTANOL Effect Assessment Result Short term exposure Acute toxicity Classified: Harmful if swallowed May cause drowsiness or dizziness Irritation/corrosion Classified: Causes skin irritation, causes serious eye damage and may cause respiratory irritation Long-term or repeated exposure Sensitization Mutagenicity Carcinogenicity Toxicity for reproduction No data available for repeated exposure No data available to consider as skin sensitizer No data available to consider as mutagen No data available to consider as carcinogen No data available to consider as reproductive toxicant ENVIRONMENTAL SAFETY OF BUTANOL Effect Assessment Aquatic toxicity Persistence and bio-accumulation Result Not classified as toxic to aquatic organisms Not classified as persistent or bio-accumulative EXPOSURE POTENTIAL Workplace exposure Production of is conducted in a closed and automated system. Potential exposure may occur during product sampling, product testing, operation of valves, pumps and during plant shut down or turn around. Each PETRONAS manufacturing facility has training programs for employees, appropriate work processes and safety equipment in place to control the exposure to. PETRONAS CHEMICALS GROUP BERHAD 2

4 is stored in closed containers and tanks, while the transfer of is carried out in closed pipelines and vessels. Exposure during transfer to tankers is controlled by automated filling equipment. Workplace exposure is managed by using appropriate personal protective equipment (PPE). Thus workers are unlikely to be exposed to as a result of engineering controls, PPE and relevant training programs. Consumer exposure PETRONAS Chemicals Group Berhad (PCGB) does not sell for direct consumer use, but they may be used in formulations which are used by consumers. Consumer exposure to will depend on a number of factors including the frequency, duration of use and concentration of in consumer products. In this case, product information label should always be read prior to use and use instructions should be followed carefully. Environmental exposure production or the use of in products could result in the release of this material to the environment through various waste streams. There are potential exposure through environmental release and accidental spill throughout the lifecycle of. The primary route for entering the environment is the release to the atmosphere when is used as a solvent. If is released to soil, it is expected to have high mobility. Therefore it will not retain in the soil to cause any of the effect associated with. If it is released to surface water, is readily biodegradable by microorganisms and will not persist in the environment. It also does not accumulate in the food chain. Furthermore, toxicity of towards aquatic organisms is very low. RISK MANAGEMENT RECOMMENDATION Note: Please refer to SDS for a comprehensive safety and first aid measures. This summary describes safety recommendations focusing on professional use. It does not replace the recommendations given in Safety Data Sheet (SDS), which should be diligently followed by industrial users. PETRONAS CHEMICALS GROUP BERHAD 3

5 Measures for protecting workers from being exposed to are as follows: Selection of specific items for protection such as face shield, boots, and apron or full-body suit will depend on the task to be carried out. Examples of preferred glove barrier materials include nitrile/butadiene rubber. Atmospheric levels should be maintained below the exposure guideline. If ventilation is not adequate, a respirator with an organic vapour cartridge should be used. Safety glasses or goggles should be worn during operations in which might affect the eyes e.g., through splashes of solution. is flammable, ignition sources such as heated substances, sparks, and open flames should not be brought close to it. With regards to personal safety, operators are advised not to eat, drink, or smoke where chemicals are handled, processed, or stored. If the substance gets into eyes, rinse immediately and thoroughly with tap water and seek medical attention. For specific advice please consult the corresponding SDS. Measures for protecting the environment from being exposed to are as follows: All effluent releases must be directed to the (municipal) waste water treatment plant prior to discharge. Appropriately treat wastewater and regularly maintain and inspect the drainage treatment facility. For leaks contain the leakage and control the spread of the contamination. Use dry absorbents to soak up the spill. Dispose the collected leakage in compliance with local regulations. Prevent the spill from entering soil, sewers, waterways and groundwater. For small spills, dilute with water or absorb with noncombustible materials such as sand. Collect waste with a shovel and place it in a suitable and properly labelled container. Note: The hazard statements and symbols presented here refer to the hazard properties of butanol and are meant to provide a brief overview of the hazard classification and labelling. It is not intended to be comprehensive or to replace information found in the SDS. The hazard classification and labelling is based on UN Globally Harmonized System of Classification and Labelling of Chemicals and as adopted by the Industry Code of Practice on Chemicals Classification and Hazard Communication, Department of Occupational Safety and Health, Malaysia.
