LAB REPORT CMT 115 EXPERIMENT 1: ELABORATION OF SDS FOR TOLUENE AS CHEMICAL HAZARD IN LABORATORY STUDENT’S NAME : NURUL NABILA BINTI ABU BAKAR STUDENT’S ID : 2020811342 LECTURER’S NAME : DR SYAFIK YAHYA Abstract : This experiment was carried out to classify Toluene by means of the seventeen section in the Material Safety Data Sheet (MSDS). MSDS is a key factor in the safety of the laboratory. Material safety data sheets (MSDSs) provide fundamental information on chemical hazards in the laboratory that form an integral part of everyday business. Material safety data sheets They are a primary resource for the communication of chemical hazards and decisionmaking in the management of risk used by health, safety and environmental professionals. From the study, the Internet, online books or reference books can identify all the features relating to the chemical. Some questions have been answered on the basis of the explanation in conclusion. Introduction : Laboratory safety is of paramount importance. That is exactly why this safety resources have been created, to encourage and promote safe and efficient working practices in any lab. Everyday, people are exposed to a variety of activities or products that could, under certain circumstances, cause harm. There is a potential for harm or injury in nearly every activity we engage in – whether it is when we cross a street, ride in an automobile, or play in a baseball game. This potential for harm can be referred to as “risk”. The terms “risk” and “hazard” may seem to have very similar meaning to most of us, but to a scientist they are actually very different. With respect to chemistry, the terms have very specific meanings: • Hazard refers to the inherent properties of a chemical substance that make it capable of causing harm to a person or the environment. • Exposure describes both the amount of, and the frequency with which, a chemical substance comes into contact with a person, group of people or the environment. • Risk is the possibility of a harm arising from a particular exposure to a chemical substance, under specific conditions. A chemical hazard generally refers to a type of occupational hazard caused by exposure to chemicals in the workplace. The hazard associated with a chemical depends on: • What the specific chemical is • What chemical(s) it is mixed with, if any • The relative proportion of the chemical, if it is in a mixture or solution with other substances and chemicals

• A Material Safety Data Sheet (MSDS) provides basic information on a material or chemical product. A MSDS describes the properties and potential hazards of the material, how to use it safely, and what to do in an emergency. The MSDS is an essential starting point for the development of a complete health and safety program for the material. MSDSs are prepared by the manufacturer or supplier of the material. • They tend to be general in nature, since they provide summarized information which tries to address all reasonably anticipated uses of the material. The information on MSDSs is organized into sections. The specific names and content of these sections can vary from one supplier's MSDS to another, but are often similar to the 16 sections of the ANSI Standard for MSDS preparation, as listed below. If you are using a 9-section MSDS, the types of information may be in a different order and under slightly different headings. Objectives : 1. To classify the MSDS identification of Toluene by using sixteen section. 2. To write down all the sixteen section for Toluene. Apparatus and Chemical : Material Safety Data Sheet Procedures : 1. 2. 3. 4.

Students should watch and understand the video presented by the lab teacher. In internet, online books or references, students can explore Toluene knowledge. Using 16 to identify Toluene's MSDS identification based on SDS identification. Toluene is explained in Table 1 below in MSDS recognition.

Explanation Identifies both the SDS chemical and the recommended applications. It also provides the supplier with important contact data. Includes the hazards of the chemical and relevant warning details related to those hazards. Identifies the ingredient(s) in the substance listed on the SDS, including impurities and stabilizing additives. This section contains information on compounds, mixtures and all chemicals where trade secrets are stated. Describes the initial treatment that untrained responders should be provided to a person who has been exposed to the chemical. Lists the recommendations for battling a chemical fire, including effective fire extinguishing methods, equipment and chemical hazards. Provides guidance on the required response to spills, leaks or releases, including containment and cleaning procedures, to avoid or mitigate damage to humans, assets or the environment. It can also provide guidelines for distinguishing between reactions to large and small spills where the amount of spills has a major effect on the threat.

Other Information

Provide instructions on proper handling practices and conditions for safe storage of chemicals, including incompatibilities. Indicates exposure restrictions, engineering monitors, and personal protective equipment (PPE) steps that can be used to reduce exposure to employees. Identifies the physical and chemical properties of the material or mixture. Describes the dangers of chemical reactivity and the details on chemical stability. This section is broken down into three parts: reactivity, chemical stability, and others. Identifies information on toxicological and health effects or suggests that such details are not available. This includes exposure mechanisms, associated symptoms, acute and chronic effects, and numerical toxicity steps. Provides information to determine the environmental effects of the chemical(s) if it has been released to the atmosphere. Provides recommendations on adequate disposal procedures, recycling or reprocessing and proper handling of the chemical(s) and its containers. This section may also refer to Section 8 (Exposure Controls/Personal Protection) of the SDS in order to limit exposure. Includes guidelines on classification of dangerous chemicals by road, air, rail or sea shipping and transport. Identifies product-specific protection, sanitary and environmental laws that are not elsewhere indicated on the SDS. Specifies the preparation of an SDS or the last recorded revision. The SDS may also show that the previous version has been modified. For a description of the changes, please contact the supplier. Here can also be included other valuable information.

Questions : 1. How do you categorize type of hazards in laboratory ? - Classify the hazards to three different class which is health hazards, physical hazards and environmental hazards. 2. Do we need to update the information in Material Safety Data Sheet (MSDS) ? Give your reason why. - Yes, because it is required to make sure that we run a safe compliant operation. 3. Steven’s hand had exposed to Chemical X and his hand become itchy and suddenly rashes appear on his hand. Which part in MSDS would you suggest for Steven to refer ? - The part in MSDS that Steven should refer is First-Aid.

Conclusion : Material Safety Data Sheet (MSDS) is important because it is a source of knowledge about health and safety. They are a crucial starting point for the development of a comprehensive material health and safety program. References and Appendices : I.
