Interpretation and use of MSDS<\/h3>\n\n\n\n

Formula (Chemical): it is a symbolic representation of chemical entity or relationship between elements, molecules and atoms.<\/p>\n\n\n\n

Synonyms: indicates alternate name of material.<\/p>\n\n\n\n

Trade name: commercial name of product.<\/p>\n\n\n\n

Chemical classification: general classification of organic or in organic.<\/p>\n\n\n\n

CAS No: it is a Chemical Abstract Service number<\/p>\n\n\n\n

  to provide a single unique identifier with naming the chemicals e.g CAS for acetic acid is 64-19-7<\/p>\n\n\n\n

UN No: it is United Nations four digit number assigned to potentially hazardous materials. This numbers are internationally recognized and used by emergency response personnel to identify material during transport emergencies.UN No: it is United Nations four digit number assigned to potentially hazardous materials. This numbers are internationally recognized and used by emergency response personnel to identify material during transport emergencies.<\/p>\n\n\n\n

EMERGENCY INFORMATION PANEL<\/h3>\n\n\n\n

\u2022 Under the amended Factories Act & Rules made therein by states, every motor vehicle carrying hazardous substances should comply with certain regulations. One of them is painting of HAZCHEM panel on tanker body in specific dimensions & at specified locations.<\/p>\n\n\n\n

\u2022 The vehicle carrying hazardous chemical should have \u2018Emergency Information Panel\u2019 on both sides and on back. In addition, relevant UN Hazard class label\u00a0 has to be displayed on the front part of the vehicle.<\/p>\n\n\n\n

\u2022 The Emergency Information Panel provides information in the event of an emergency. It indicates the correct technical name of the substance being transported. Its UN number, Hazchem code and UN Hazard class label. The panel also provides telephone number for contact incase of an emergency, and for special advice.<\/p>\n\n\n\n

\u2022 Each term in the emergency information panel is explained as shown below<\/p>\n\n\n\n

1. Left side top of rectangular panel shows correct technical name of the chemical.<\/p>\n\n\n\n

2. Below technical name, UN number, Hazchem & emergency telephone number are listed one below the other respectively.<\/p>\n\n\n\n

3. On right side top of the panel, a class label alongwith subsidiary risk label (if any) is shown. 4. At right bottom, related class label, specialist advice is indicated.<\/p>\n\n\n\n

HAZCHEM CODE<\/strong><\/h3>\n\n\n\n

One has to fall back on three aspects to derive the code.<\/p>\n\n\n\n

1. Fire or spillage \u2013 select 1 to 4 as indicated in the table.<\/p>\n\n\n\n

2. Select either \u2018DILUTE\u2019 or \u2018CONTAIN\u2019 aspect and accordingly decide respiratory protection.<\/p>\n\n\n\n

3. Last aspect is on \u2018EVACUATION\u2019.<\/p>\n\n\n\n

\u2022 ADR No: it is an Agreement concerning carriage of Dangerous goods by Road.<\/p>\n\n\n\n

\u2022 This European agreement was arrived at Geneva by 19 European countries for the safety of international transport by road.<\/p>\n\n\n\n

\u2022 It deals with the classification of hazardous substance, their packaging, loading and unloading, transportation and its equipment<\/p>\n\n\n\n

\u2022 It gives hazard identification numbers like UN hazard class number.<\/p>\n\n\n\n

\u2022 Specific gravity: it is the ratio of density of material to the density of water. Lighter material will float and heavier will sink.<\/p>\n\n\n\n

\u2022 It is useful for spill and fire control.<\/p>\n\n\n\n

\u2022 Vapor density: It is the vapor weight per unit volume. In MSDS, it is given ratio of density of a gas or vapor to the density of air.<\/p>\n\n\n\n

\u2022 Boiling point: it is the temperature at which material changes from liquid to gas.<\/p>\n\n\n\n

\u2022 Melting point: it is the temperature at which a solid material melts and becomes a liquid. This information is useful for storage and handling purpose.<\/p>\n\n\n\n

\u2022 Freezing point: it is the temperature at which a liquid material freezes and becomes solid.<\/p>\n\n\n\n

\u2022 Vapor pressure: it is the pressure upon atmosphere of vapor of material at a fixed temperature. Higher vapor pressure indicates higher concentration and therefore higher hazard to fire or inhalation.<\/p>\n\n\n\n

\u2022 Solubility: ability of a material to dissolve in water or another liquid.<\/p>\n\n\n\n

\u2022 Flash point: it is the lowest temperature at which a material gives off enough vapor near its surface to form a flammable air vapor mixture so that it can be ignited if spark is available.<\/p>\n\n\n\n

TDG Flammability:<\/strong><\/p>\n\n\n\n

Transport of Dangerous Goods classifies the materials according to their flammability as under;<\/p>\n\n\n\n

\u2022 2.1 flammable gas<\/p>\n\n\n\n

\u2022 3\u00a0\u00a0 flammbale liquid<\/p>\n\n\n\n

\u20224.1 flammbale solid<\/p>\n\n\n\n

\u2022 4.2 spontaneous combustible material<\/p>\n\n\n\n

\u2022 4.3 material which gives off a flammble gas on contact with water.<\/p>\n\n\n\n

Chemical Hazard Information<\/h2>\n\n\n\n

\u2022 Chemical labels: National Fire Prevention Association (NFPA) Fire Rating<\/p>\n\n\n\n

\u2022 Material Safety Data Sheets (MSDS)<\/p>\n\n\n\n

Safety and Risk Phrases:<\/h2>\n\n\n\n

\u2022 Regulation 9 of Chemical Hazards Information and Packaging gives requirements for the labeling of substance and preparation dangerous for supply.<\/p>\n\n\n\n

\u2022 It includes name and address of supplier, information of substance, symbols and safety and risk phrases.<\/p>\n\n\n\n

\u2022 These phrases are represented by number and their specific meaning indicating type of hazard in brief.<\/p>\n\n\n\n
