1/28

(Control of Substances Hazardous to HealthRegulations,2004)


2/28

Substances & mixtures classifiedas dangerous under CHIP (Chemicals (Hazard Information andPackaging for Supply) Regulations2008 )

Substances with WELs(Workplace exposure limits)

Biological agents

Some dusts, especially in highconcentrations

Other substances of comparablehazard


3/28

Lead and Asbestos (separateregulations)

Substances only hazardous due to: Radio-activity Simple asphyxiants High pressure or extremes of

temperature

Biological agents not connected withwork

Eg Swine flu or catching a cold from acolleague

Labels are a good guide!


4/28

Eliminate or reducerisks from hazardoussubstances

This is achieved by:Risk assessmentControl measuresMonitoring health &exposure if necessaryInformation, trainingand supervision


5/28

Take reasonable care ofour own safety and notendanger othersCooperate with ouremployerMake full and proper useof control measure

Just reiterating our dutiesunder HSAW


6/28

Identify the hazardoussubstance(s) eg

Chemicals Biological materials Mixtures

Proprietary products Reaction products and

intermediates


7/28

New International Hazard Symbols

Danger Flammable Oxidiser


8/28


Explosive Corrosive Compressed orliquefied gas


9/28


Aquatic Warning Sensitiser, carcinogen,Toxicity mutagen or teratogen


10/28

OTHER SYMBOLS YOU MIGHT SEEWHAT DO THEY MEAN


11/28

FLAMMABLE EXPLOSIVE

HARMFUL TO THEENVIRONMENT

IRRITANT /HARMFUL

TOXIC

HIGHLYFLAMMABLE

CORROSIVE

OXIDISING BIOLOGICAL

AGENT

VERY TOXIC


12/28

Use available data eg.

Data sheets & labels

Workplace exposure limits(WELs) see Safety Servicesweb site

On-line databases

Previous experience &publications

(Especially for novel products)


13/28


14/28

InhalationSkin or eye

contaminationIngestionInjection


15/28

Factors to Consider: Toxicity Form (gas, spray, dust,

liquid, solid)

Solubility Amount (weight &/or

volume) Nature of the operation Length of exposure Number of people

involved

OR


16/28

Control exposure inproportion to riskby using thehierarchy ofcontrols.

Personal protectiveequipment shouldbe a last resort asthe prime means ofcontrol ?


17/28

Replace substancewith a saferalternative

Eg use a lowerhazard disinfectantrather than bleach

(irritant) if it will dothe job adequately


18/28

Use the material in asafer form eg:

Use water-based paint

instead of solvent-based paint

Buy hazardousmaterials in pre-weighed sachets ratherthan having to measure& make-up from bulkquantities


19/28

Control theoperation eg Isolate the work Control at source

Fume cupboardLocal exhaustventilation

Reduce the number

of workers Reduce the frequency


20/28

Personal protectiveequipment as a lastresort: Protects only the

worker & not othersin the room

Training &maintenancerequired

Often not verycomfortable


21/28

Good laboratorytechniques is vitaleg. Labelling Correct substance

storage Warning signs where

appropriate Cleanliness & tidiness Correct waste disposal


22/28

Must be kept in goodrepair & working properly

Regular simple checks onairflowLEV & fume cupboardsmust have engineeringchecks every 14 monthsRecords kept for 5 years


23/28

Measure concentrations where assessmentconcludes that: There is a serious risk if controls fail Exposure limits may be exceeded Control measures may not be working properly Employees are involved in certain specific work in

Schedule 5 (unlikely in the University apart frompossibly use of vinyl chloride monomer)

Records must be kept for 5 years


24/28

Only required if:

Significant exposure of Schedule 6processes (apart from vinyl chlorideuse, these are all manufacturing

processes) Likelihood of exposure to substances

linked to specific diseases but only if:There is a reasonable likelihood that thiswill occurIt is actually possible to detect the diseaseor effect

Records to be kept for 40 years

Safe waste disposalEmergencyprocedures Spillage Fire First aid


26/28

InformationInstructionTrainingSupervision

This will includethe proceduresthemselves andwhat to do in anemergency


27/28

Are the control measuresadequate?

Are they working correctly?

Is everyone aware of how touse them?

Have you the necessaryequipment to deal with anemergency or malfunction?


28/28

If you are working in a Science, Medicine orEngineering department, you should now findout the specific forms and methods used inyour department for CoSHH assessments.

If you are working mainly with proprietaryproducts (cleaning materials, lubricants,

household chemicals etc), you may find ituseful to complete the presentation onexamining data sheets
