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 contain?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 contain?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 skinLarge amounts could be hazardous to

aquatic environment

What do MSDSs contain?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 contain?What do MSDSs contain?Fire fighting measures

The material is non-flammableIf 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 contain?What do MSDSs contain?Measures for spillage or accidental

releaseSpillage

◦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.

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

What do MSDSs contain?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 what sortsort of 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 contain?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 contain?What do MSDSs contain?Stability & reactivityNo 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 contain?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 irritationIngestion – 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 contain?What do MSDSs contain?Ecological informationHow 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 contain?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 contain?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 contain?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”.

REMEMBERREMEMBERMSDS’s are NOTNOT 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 riskControls should be proportional to risk!Not all MSDS’s contain comprehensive.
