2To get familiar with Material Safety Data Sheets Session ObjectivesTo get familiar with MaterialSafety Data SheetsTo know how to properly findand use the MSDS
3MSDS: 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.
4MSDS LocationMSDS 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.
5MATERIAL SAFETY DATA SHEET Information on Material Safety Data Sheet is organized in 16 Section as follows.Material IdentityComposition / Information on IngredientPhysical & Chemical DataFire and Explosion Hazard DataStability and ReactivityHealth Hazard Data / Toxicological InformationFirst Aid MeasuresFire Fighting Measures

7The MSDS includes following details Material IdentityNameSynonymsFormulaUN 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

10Fire 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.FlammabilityLower/ Upper Explosive Limit
11FlammabilityLimits 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 volumeconcentration below which the mixture is too less to burn.•• UEL or Upper Explosive limit-- The percent by volumeconcentration above which the mixture is too rich to burn.•• The flammable range consists of all the concentrations between these two limits.

13Health Hazard Data / Toxicological Information Routes of entryEffects of exposureTLV ( 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.
14Definition: LD50LD50 (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.
15Definition: LC50LC50 (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.

18Accidental Release Procedure Spill or leak procedures
19When a Spill Strikes) Assess the riskMinor 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 spillsmay require special treatment, equipment or emergency assistance.
20When 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 sourcesLimit the spill area by blocking, diverting, or confining spillUse absorbents, drain plugs, dikes.Stop the Source if possible.Decontaminate site, personnel, & equipment by removing or neutralizing the hazardous materials
