Presentation on theme: "MATERIAL SAFETY DATA SHEET"— Presentation transcript:


2 To get familiar with Material Safety Data Sheets
Session Objectives To get familiar with Material Safety Data Sheets To know how to properly find and use the MSDS

3 MSDS: Material Safety Data Sheet
It requires for each chemical. It requires to operators, officers and chemist review. It must be accessible for everyone in the labs, shop floor, Stores, etc.

4 MSDS Location MSDS are required to be easily accessible by you at all times. Don’t necessarily have to be located in each lab (although it is a good idea) Ask your supervisor where they are located in your area.

Information on Material Safety Data Sheet is organized in 16 Section as follows. Material Identity Composition / Information on Ingredient Physical & Chemical Data Fire and Explosion Hazard Data Stability and Reactivity Health Hazard Data / Toxicological Information First Aid Measures Fire Fighting Measures

Accidental Release Measures Handling & Storage Exposure Control and Personal Protection Environmental / Ecological Information Disposal Consideration Transport Information Regulatory Information 16.Manufacturer / Suppliers Data

7 The MSDS includes following details
Material Identity Name Synonyms Formula UN No. CAS No. ( Chemical Abstracts Service registry No.) - Unique number assigned to a specific chemical by the American Chemical Society and indexed in Chemical Abstracts published by Chemical Abstracts Service in the US. These nos. are used widely for accurate identification of materials and quick retrieval of their chemical and Safety information. Chemical Classification

8 Composition / information on Ingredient
Ingredients Percentage

9 Physical & Chemical Data
Appearance Odour pH Boiling Point Melting Point Physical State Vapour Pressure Vapour Density Specific Gravity

10 Fire and Explosion Data
Flash Point - The lowest temperature at which the vapor above the liquid will ignite if an ignition source is present. Auto Ignition Temperature - The minimum temperature required to initiate or cause self-sustained combustion which is independent of a spark or flame source. Flammability Lower/ Upper Explosive Limit

11 Flammability Limits of flammability--Each flammable gas and liquid (in the form of a vapor) has two limits which define the range of concentrations in mixtures with air that will propagate flame and explode. •• LEL or Lower Explosive limit--The percent by volume concentration below which the mixture is too less to burn. •• UEL or Upper Explosive limit-- The percent by volume concentration above which the mixture is too rich to burn. •• The flammable range consists of all the concentrations between these two limits.

12 Stability and Reactivity
Chemical Stability Chemical Compatibility Hazardous Reaction Products Reactivity

13 Health Hazard Data / Toxicological Information
Routes of entry Effects of exposure TLV ( Threshold Limit Value) -The concentration of an airborne substance to which an average person can be repeatedly exposed without adverse effects for 8 Hrs.. STEL( Short Term Exposure Limit) – It is expressed as airborne concentration of substances average over a period of fifteen minutes. Workers should not be exposed at the STEL concentration continuously for longer than fifteen minutes, or for more than four such periods per working day. One hour gap must be there between two exposures. IDLH ( Immediately Danger to Life/ Health) - Air concentration at this level can cause death very quickly; can be caused by toxic chemicals, insufficient oxygen, or both.

14 Definition: LD50 LD50 (Lethal Dose50) is the amount of a substance that, when administered by a defined route of entry (e.g. oral or dermal) over a specified period of time, is expected to cause the death of 50 per cent of a defined animal population.

15 Definition: LC50 LC50 (Lethal Concentration50) is the amount of a substance in air that, when given by inhalation over a specified period of time, is expected to cause the death in 50 per cent of a defined animal population.

16 First Aid Measures Eyes Skin exposure Inhalation Ingestion

17 Fire Fighting Measures
Extinguishing Media Special Fire Fighting Procedures

18 Accidental Release Procedure
Spill or leak procedures

19 When a Spill Strikes ) Assess the risk Minor Spill, handled by personnel within lab or department. Minor spills should be cleaned-up at the time of the spill. Major Spill, isolate area. Major spills may require special treatment, equipment or emergency assistance.

20 When a Spill Strikes Consult MSDS and other literature sources
Select personal protective equipment (PPE) such as rubber gloves and goggles. Consult MSDS and other literature sources Limit the spill area by blocking, diverting, or confining spill Use absorbents, drain plugs, dikes. Stop the Source if possible. Decontaminate site, personnel, & equipment by removing or neutralizing the hazardous materials

21 Handling & Storage Minimum / Maximum storage temperature Handling
Ventilation Storage

22 Exposure Control and Personal Protection
Ingestion Eye Contact Skin Contact Respiratory Protection Engineering Controls

23 Environmental / Ecological Information
Eco – acute toxicity Environmental fate

24 Disposal Information Provide guidance for disposal, incineration of the material at facility that complies with local state and Federal regulations

25 Transport Information
Proper Shipping Name Hazard class UN No. Special Information Packing group

26 Hazard Classifications
Class 1 – Explosives Class 2 - Gases

27 Hazard Classifications
Class 3 – Flammable Liquids (and Combustible Liquids) Class 4 – Flammable Solids; Spontaneously Combustible Materials; Dangerous When Wet Materials

28 Hazard Classifications
Class 5 – Oxidizers and Organic Peroxides Class 6 – Toxic Materials and Infectious Substances

29 Hazard Classifications
Class 7 – Radioactive Materials Class 8 – Corrosive Materials

30 Hazard Classifications
Class 9 – Miscellaneous Dangerous Goods

31 Packing Groups Packing Group LD 50 Value
Three categories of packaging The Packing Group (PG) is based on the hazard(s) of the product LD 50 Value Packing Group I - Great danger ( <= 5) Packing Group II - Moderate danger (<= 50) Packing Group III - Mild danger (<=200)

32 Regulatory Information
Risk Phrases R1: Explosive when dry R2: Risk of explosion by shock, friction, fire or other sources of ignition R3: Extreme risk of explosion by shock, friction, fire or other sources of ignition R4: Forms very sensitive explosive metallic compounds R5: Heating may cause an explosion R6: Explosive with or without contact with air R7: May cause fire R8: Contact with combustible material may cause fire R9: Explosive when mixed with combustible material R10: Flammable R11: Highly flammable R12: Extremely flammable R14: Reacts violently with water

33 Regulatory Information
Safety Phrases S1 : Keep locked up S2 : Keep out of the reach of children S3: Keep in a cool place S4: Keep away from living quarters S5: Keep contents under ... (appropriate liquid to be specified by the manufacturer) S6: Keep under ... (inert gas to be specified by the manufacturer) S7: Keep container tightly closed S8: Keep container dry S9: Keep container in a well-ventilated place S12: Do not keep the container sealed S13: Keep away from food, drink and animal feedingstuffs S14: Keep away from ... (incompatible materials to be indicated by the manufacturer) S15: Keep away from heat S16: Keep away from sources of ignition - No smoking S17: Keep away from combustible material S18: Handle and open container with care S20: When using do not eat or drink
