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)
slide12

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?
  • 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?
  • 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?
  • 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?
  • 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?
  • 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?
  • 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
Risk phrases - examples
  • R1: Explosive when dry

  • R68: Possible risk of irreversible effects
what do msdss contain15
What do MSDSs contain?
  • Other information (variable)
  • In this case it tells you its immediate application and how to use it
remember
REMEMBER
  • 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.
