1. Introduction

1.1 Customs officers often have to deal with chemicals while inspecting/examining import/export consignment of chemicals or taking samples for testing etc. They are also required to handle chemicals while stock taking in manufacturing premises or godowns. Sometimes the officers also have to supervise transport and storage of chemicals especially those seized by the officers. They need to be extremely careful while dealing with chemicals. Slight mistake in dealing with or handling chemicals may pose risk to their life as well as life of others. In this regard, it is important for Customs officer to know about Material Safety Data Sheets (MSDSs) accompanying these chemicals. The information contained in MSDSs is vital for the safety of individuals as well as the environment. Such knowledge will not only enable them to do their job efficiently, but will ensure their own safety.

1.2 The use of chemicals to enhance and improve life is a widespread practice worldwide. While on one side, there are benefits of using these chemicals, on other side, there is also potential for adverse effects to people or the environment. To ensure enhanced protection of human health and the environment, there is need that all stake holders such as workers, consumer, transport workers, emergency responders, public in general are effectively communicated the various hazards associated with the Chemical.

1.3 The various hazards associated with chemicals may be broadly put into three categories-

(i) Physical hazards such as explosive, inflammable solid/liquid/gas, self-reactivity; oxidizing liquid/solid; pyrophoric liquids/solids etc.

(ii) Health Hazards such as acute toxicity-oral or dermal; skin corrosion/ irritation; serious eye damage/eye irritation; respiratory/skin sensitization; specific target organ toxicity; germ cell mutagenicity; carcinogenicity, reproductive toxicity, aspiration hazard, poisonous, infectious, radioactive etc.

(iii) Environmental Hazards such as very toxic/toxic/harmful to aquatic life; adverse impact on ozone layer etc.

1.4 Communication of various hazards to various stake holders dealing with these chemicals at place of manufacture, workplace, storage, transportation, port/airports, warehouses etc. is an important part of strategy to protect people and environment. Requirement of labeling and safety Data Sheets (SDS) forms important elements of effective Chemical Hazard Communication System.

1.5 While basic details of Safety Data Sheets have been explained in this e-book, the details about classification of hazards, requirement for labeling of chemicals or requirement for safe transportation of hazardous chemicals are available in e‑book on Globally Harmonized System of classification and Labeling of Chemicals (GHS).

2. What are Material Safety Data Sheets (MSDSs) and who prepares them?

2.1 Material Safety Data Sheets (MSDSs) are documents prepared by the manufactures/ suppliers of the chemicals and contain information on physical and chemical properties of the material, potential hazards of the material and how to work safely with these materials. They also contain information on usages, storage, handling and emergency procedures related to the hazards of the materials. In fact, they provide a single reference for all information about hazardous substances.

2.2 MSDSs provide information on chemicals, chemical compounds and chemical mixtures and are primarily intended for use by the personnel working with hazardous chemical substances.

2.3 MSDSs need to be updated every three years, but if any significant new information becomes available about the material, then it should be incorporated into MSDS even before lapse of three years.

2.4 The revised (Material) Safety Data Sheets (SDS) contains Sixteen (16) Sections, however, different countries provide for 9 to 16 sections and their format varies from country to country. As per purple book on GHS, the information in the SDS should normally be presented using the following 16 headings in the order given below:

(1) Identification

(2) Hazard (s) identification

(3) Composition/ information on ingredients

(4) First-aid measures

(5) Fire-fighting measures

(6) Accidental release measures

(7) Handling and Storage

(8) Exposure controls/personal protection

(9) Physical and Chemical Properties

(10) Stability and reactivity

(11) Toxicological information

(12) Ecological information

(13) Disposal Considerations

(14) Transport information

(15) Regulatory information

(16) Other information

3. Legal requirements on the Form and Content of MSDSs.

3.1 Annexure 4 of the revised Purple Book of United Nation’s Globally Harmonized System of Classification and Labelling of Chemicals (UN GHS) provides for the content and format of Safety Data Sheets. Since it is not a binding regulation of the UN, countries are required to promulgate their own regulations.

3.2 United States of America: In the US, MSDSs are mandated by the Occupational Safety and Health Administration (OSHA) through Hazard Communication Regulation. MSDSs are reviewed by US Chemical Safety and Hazard Investigation Board.

3.3 Canada: In Canada, the requirement of MSDS is mandated by Hazardous Product Act, Part II and the Controlled Products Regulations under program known as Workplace Hazardous Materials Information System (WHMIS).

3.4 Europe: In Europe, MSDS are mandated by EU legislation introduced by Regulation (EC) No 1272/2008 (CLP) via an updated Annexure II of REACH.

3.5 India: In India, MSDS contain 9 Sections listed under Schedule 9 of “The Manufacture, Storage and Import of Hazardous Chemicals Rule, 1989”.

These numbers generally range between 0000 and 3500 and are ideally preceded by the letters “UN” (for example, “UN1 008”) to avoid confusion with other number codes.

5. Shipping Name: Name indicted against the specific U.N. No.

6. Codes/Label/Class: The classification of goods by the type of goods involved. The hazards transport of goods is sub-divided to show the primary hazard of the substance, which determines the Class into which the substance is assigned, and, where appropriate, the subsidiary risks. The classifications identified are those adopted by the United Nations Committee of Experts on the Transport of Dangerous Goods and on the Globally Harmonised System of Classification and Labeling of Chemicals, and are as follows:

Class 1: Explosives: Substances which may explode under the effect of flame heat, heat or photochemical conditions, or which are more sensitive to shocks or friction than dinitrobenzene. A substance which is not itself an explosive but which can form an explosive atmosphere of gas, vapour or dust is not generally included in Class 1.

Class 2: Gases – compressed, liquefied, dissolved under pressure or deeply refrigerated. Some gases are flammable; others non-flammable.

Class 3: Inflammable (flammable) liquids: These are liquids or mixture of liquids, or liquids containing solids in solution or suspension having flash point of not more than 60.5 degree C (closed-cup), or not more than 65.6 degree C (open-cup).

Class 4: (i). Inflammable solids

(ii) Substances liable to spontaneous combustion

(iii) Substances which, in contact with water, emit flammable gases.

(ii). Organic peroxides

Class 6: (i). Poisonous (toxic) substances

(ii). Infectious substances

Class 7:  Radioactive substances

Class 8:  Corrosive substances

Class 9:  Miscellaneous dangerous substances not covered by other classes.

7. Hazchem Code : Emergency Action codes (EACs) , also known as Hazchem, are for the use of the emergency services in conjunction with Emergency Action Code Cards. EACs indicate to the emergency services actions that may be necessary, during the first few minutes of an incident involving dangerous goods, should the officer in charge of the incident deem it necessary to take immediate actions. The code uses one of the numerals 1, 2, 3 or 4 followed by one or two letters.

8. Hazardous Waste I.D. No. : Hazardous Waste Identification number as indicated under categories of Wastes in the Schedule of the Hazardous Wastes (Management and Handling) Rules 1989.

9. TDG Flammability : Transport of Dangerous Goods Flammability. This term is used in Canada and is based on Classifications of Dangerous Goods by the U.N. Committee of experts on Transport of Dangerous Goods. The Classes indicated are 2 (flammable), 3, 4 and 5.

10. LD50 (Oral) :Lethal Dose Fifty (Oral) – a calculated orally ingested dose of a material which is expected to cause the death of 50% of an entire defined experimental animal population. Generally animals are rat, mouse or rabbit.

11. LC50 : Lethal Concentration Fifty – a calculated concentration of a material in air, exposure to which for a specified length of time, hours (H), month (M), or week (W), is expected to cause the death of 50% of entire defined experimental animal population.

12. Permissible Exposure Limit : Permissible Levels of certain Chemical Substances in Work Environment as laid down in the Second Schedule of the Factories Act.

13. Threshold Limit Value – Short-Term Exposure Limits: The parts of vapor (gas per million parts of contaminated air by volume at 25o C (77o F) and one atmosphere pressure is given. The limits are given in milligrams per cubic meter maximum permissible average exposures for the time periods specified.

14. ppm : Parts per million parts of air.

15. mg/m3 : Milligram per cubic metre.

16. NFPA Hazard Signals : National Fire Protection Associations USA Hazard Signal – A simple, readily recognizable and easily understood markings (alerting signals) which give at a glance a general idea of the inherent hazards of the material and the order of severity of these hazards as they relate to fire prevention, exposure and control. The system identifies the hazards of a material in terms of three categories – Health, Flammability and Reactivity, and indicates the order of severity in each of these categories. Another category (special) is reserved for additional information when such may be of value to the fire fighter.

17. Chemical Classification (Hazardous): The chemicals hazard classification as per the Corrosive Reactive Explosive Flammable Toxic (CREFT) Classification.

18. ACGIH : The American Conference of Governmental Industrial Hygienists, Inc., ACGIH, is an organization open to all practitioners in industrial hygiene, occupational health, environmental health, or safety. Their web site is http://www.acgih.org/.

19. Asphyxiant: An asphyxiant is a substance that can cause unconsciousness or death by suffocation (asphyxiation). Asphyxiants which have no other health effects and are sometimes referred to as simple asphyxiants. Asphyxiants work by displacing so much oxygen from the ambient atmosphere that the hemoglobin in the blood can not pick up enough oxygen from the lungs to fully oxygenate the tissues. As a result, the victim slowly suffocates.

20. Flammable limits : Flammable limits apply generally to vapours and are defined as the concentration range in which a flammable substance can produce a fire or explosion when an ignition source (such as a spark or open flame) is present. The concentration is generally expressed as percent fuel by volume.

a. Above the upper flammable limit (UFL) the mixture of substance and air is too rich in fuel (deficient in 51oxygen) to burn. This is sometimes called the upper explosive limit (UEL).

b. Below the lower flammable limit (LFL) the mixture of substance and air lacks sufficient fuel (substance) to burn. This is sometimes called the lower explosive limit (LEL). Any concentration between these limits can ignite or explode — use extreme caution! Being above the upper limit is not particularly safe, either. If a confined space is above the upper flammable limit and is then ventilated or opened to an air source, the vapor will be diluted and the concentration can drop into the flammable limit range.

21. Flash Point : This is defined as the lowest temperature at which vapors above a volatile combustible substance will ignite in air when exposed to a flame. Depending on the test method used, the values given are either Tag closed cup (C.C.) (ASTM D56) or Cleveland open cup (O.C.) (ASTM D93). The values, along with those in 6.2 and 6.7 below, give an indication of the relative flammability of the chemical. In general, the open cup value is about 1 0o to 1 5o F higher than the closed cup value.
