Material Safety Data Sheets

MSDS – what you need to know

about them


Preparation
Preparation:

  • Before you go any further, it would be helpful to download:

    • Data sheet (click here) – to view the data sheet you will need to be in slide show, press F5

    • This product, used as an example, is a commercial cleaning product containing some hazardous chemicals


What do msdss contain
What do MSDSs contain?

  • Identification of the product

  • Teepol Aluminium Cleaner

    • - sales unit and stock code

    • - address and contact details for the supplier


What do msdss contain1
What do MSDSs contain?

  • Composition/ information on ingredients. (Exact formulations & details of non-hazardous components not required – protects from rival manufacturers)

  • CAS & EINECS are identifications codes

  • Risk phrases (from CHIP data- see later)

  • Alcohol Ethoxylate <1%

  • Phosphoric acid 15 – 30%

  • Benzotriazole <1%

  • Formaldehyde <1%


What do msdss contain2
What do MSDSs contain?

  • Hazards identified (i.e. those known about when the product is used in the way the manufacturer intends)

  • Irritating to eye and skin

  • Large amounts could be hazardous to aquatic environment


What do msdss contain3
What do MSDSs contain?

  • First aid measures

    • Eyes - irrigate with water 10-15 minutes

    • Skin – remove gloves and wash

    • Ingestions – plenty of water to drink

      • (This is incorrect - should be small sips!!)

    • Inhalation- remove to fresh air

  • Always check out first aid information with your Departmental First Aider or Safety Services


What do msdss contain4
What do MSDSs contain?

  • Fire fighting measures

  • The material is non-flammable

  • If involved in a fire anyway, it may produce hydrogen chloride (an acid gas)

  • Breathing apparatus is relevant to the Fire Service – not us!


What do msdss contain5
What do MSDSs contain?

  • Measures for spillage or accidental release

  • Spillage

    • contain with sand or earth

    • Beware of slipping hazard

    • Do not allow to go down the drains (report any significant leakage down the drains to the water authorities – take advice)

  • You will need to ensure that your department stocks appropriate materials to deal with these incidents.


What do msdss contain6
What do MSDSs contain?

  • Handling and storage

  • Store away from food

  • Tightly closed containers

  • Away from children

  • At temperatures between 5oC & 30oC

  • Shelf life 1 year

  • In this case, largely “common sense” information but for some products it could be more critical


What do msdss contain7
What do MSDSs contain?

  • Exposure controls &/or personal protective equipment (PPE)

    • These are standard safety signs denoting the need to wear gloves, face shield and protective clothing.

    • NB It does not tell you whatsortof gloves are appropriate. You would need to find this out by consulting a gloves manufacturer regarding the hazardous materials in the product – see the “Guidance” section of Safety Services website


What do msdss contain8
What do MSDSs contain?

  • Physical & Chemical Properties

    • Appearance – what it looks like

    • pH – acidity/alkalinity of the product – a pH of <1 denotes significant acidity

    • Flash point – it is not flammable

    • Density (>1 means it is more dense than water)


In terms of hazard, both high pHs (strong alkali) and low pHs (strong acid) are nasty. For substances with pHs around 7 acidity & alkalinity are not generally a problem.


What do msdss contain9
What do MSDSs contain? pHs (strong acid) are nasty. For substances with pHs around 7 acidity & alkalinity are not generally a problem.

  • Stability & reactivity

  • No stability concerns – it won’t “go off”

  • Avoid contact with strong oxidisers, chlorine & chlorine products – nasty gases possible

  • Contact with some alloys may produce hydrogen – explosion potential because of low pH! (but not in normal use)


What do msdss contain10
What do MSDSs contain? pHs (strong acid) are nasty. For substances with pHs around 7 acidity & alkalinity are not generally a problem.

  • Toxicological information (what nasty things will it do to you?)

  • Irritating to organic tissue (skin & eyes)

  • Inhalation of aerosol may cause irritation

  • Ingestion – irritation to mouth & digestive tract (it’s a strong acid)

  • Eye contact – may cause severe irritation (acid again!)

  • Skin contact – irritation!

  • Connected with first aid information here, but in some circumstances, may give details of longer term medical problems, where appropriate


What do msdss contain11
What do MSDSs contain? pHs (strong acid) are nasty. For substances with pHs around 7 acidity & alkalinity are not generally a problem.

  • Ecological information

  • How environmentally friendly is it?

    • Biodegrades – does not remain in soil etc

    • Don’t release into surface waters

      eg detergents can cause unsightly rivers and may

      affect waterproofing of water birds


What do msdss contain12
What do MSDSs contain? pHs (strong acid) are nasty. For substances with pHs around 7 acidity & alkalinity are not generally a problem.

  • Disposal considerations

    • Use suitable PPE (see previous information)

    • Rinse out containers

    • Don’t allow to enter drains

    • Dispose of according to local regulations

    • Do not mix with other waste

  • This is not as formidable as it

    sounds – a bit of advice from Safety Services or Estates will help


What do msdss contain13
What do MSDSs contain? pHs (strong acid) are nasty. For substances with pHs around 7 acidity & alkalinity are not generally a problem.

  • Transport information

    • None

    • Where substances need special consideration for transport, it will be detailed here – usually only applicable to larger quantities


What do msdss contain14
What do MSDSs contain? pHs (strong acid) are nasty. For substances with pHs around 7 acidity & alkalinity are not generally a problem.

  • Regulatory information

    • Irritant to eyes and skin

    • Keep away from children

    • First aid information

    • These are “risk phrases” associated with the CHIP regulations – simple advice phrases

    • There may also be symbols – as here , indicating “irritant”.


Risk phrases examples

What do msdss contain15
What do MSDSs contain? pHs (strong acid) are nasty. For substances with pHs around 7 acidity & alkalinity are not generally a problem.

  • Other information (variable)

  • In this case it tells you its immediate application and how to use it


Remember
REMEMBER pHs (strong acid) are nasty. For substances with pHs around 7 acidity & alkalinity are not generally a problem.

  • MSDS’s are NOT Risk Assessments!

  • They make no distinction between a gram and a tonne of a substance.

  • When using substances you must carry out a risk assessment but use the information in MDSD’s to help you.

  • Controls should be proportional to risk!

  • Not all MSDS’s contain comprehensive. information, although they should have!

  • If in doubt, always consult an expert.
