3France (Risk Potential Hierarchy) Chemicals are assigned to categories based on:hazard classification and labelling (I–V),frequency of use (I–IV), andquantity used (I–V).Quantity and frequency of use scores are combined to create a classification by potential exposure (I–V, based on expert opinion).The scores for hazard and potential exposure are combined to give an overall product score and priority classifications (A=elevated, B=middle, and C=weak)French only.
4The Netherlands (Stoffenmanager) Web-based tool for SMEs for working safely with chemical substancesGives qualitative risk score; allows employer to select various control measures based on score (similar to COSHH Essentials)Can provide expert analysis using its quantitative exposure assessment score (requires expert user)The program does both inhalation and skin risk assessmentsAccessible in English
5Norway (KjemiRisk)https://chemirisk.ohs.noChemicals are grouped into one of five health hazard categories based on R- and S-phrasesDeveloped for Norwegian (offshore) oil industryKjemiRisk application the asks user:about common tasks & handling of the chemicalits physical stateduration and frequency of usepotential for exposurethe appropriateness of controls in placeIn hands of hygienist can be an expert analysis toolIf used buy others provides rough qualitative (Red, Orange and Green risk ranking)English accessible
6Belgium (Regetox and SOBANE) Regetox uses the French Risk Potential Hierarchy approach to first rank hazards and then uses the COSHH Essential model to develop recommended controls for highest risk exposures (Available in French and Dutch)SOBANE uses a screening approach to identify main problems and solve simple ones immediately, then observation process is used to solve more complex ones with the help of experts (Available in French and Dutch)
7Singapore (SQRA) and Korea (KCT) Both are recently developed systems similar to COSHH Essentials and are based on the International Chemical Control Toolkit (ILO)The Korean tool is only open to members while the Singapore SQRA is paper based tool and can be found at:
8Germany (Chemical Management Guide) Two part chemical management scheme:Module 1 – Identifying Hot SpotsModule 2 – Making a Comprehensive InventoryPaper based and available in EnglishUses ILO and COSHH Essentials classification process to rank hazards into control bands in Module 2
9Control Banding Models Summary All attempt to provide a qualitative assessment of risk with the aim of getting employers to take action now rather than waiting until they get monitoring resultsMost use processes similar to COSHH Essentials to group chemicals into similar control bands based on R-phrasesSome can be used for quantitative risk assessment with the addition of more data by expertsAll are quite conservative in assigning control bands and in the recommendation of controlsValidation exercises have shown that the models recommend controls that are equal to or greater than those recommended by hygienists in 85 to 90% of cases.
10Control Banding Models Summary Problems have occurred mostly in the adequacy of controls that were implemented. In some cases, particularly those involved with LEV use for dusts, controls failed to bring exposure down below OELs (i.e. hygiene monitoring is still required to validate effectiveness of controls)All models have problems dealing with complex exposure situations. They tend to default frequently to calling in an expert.North American adoption has been slow because of the lack of R-phrases on MSDS.
11Control Banding Models Summary Where they have been implemented user acceptance has been quite high (80%) and most (>50%) have implemented controls as a result of using the models.Models all show great promise in motivating non-experts to take action on control of chemicals.
16Module 1 – Step 1 Fact finding & Identification of possible “hot spots” Draw a ground plan of the company and use it on a site walk through to identify areas where:waste, loss, contamination or expiry of a substancepotential hazards created in the way that chemicals are stored, mixed, transported and usedLook for strong chemical smells, spills, dust clouds, spoiled or expired chemicals, places where workers complain about health effects or created makeshift controls
18Module 1 - Step 2: Analysis of effects related to costs, hazards and environmental impacts
19Module 1 - Step 3: Analysis of causes – Why are chemicals being wasted, why do risks exist?
20Module 1 - Step 4: Development of measures Minimise the number of workers exposedMinimise the duration and intensity of exposureReduce the quantity of chemical agentsAppropriate hygiene measuresProvide suitable equipment and establish safe maintenance proceduresDesign and organisation of processes, layouts and workplacesSuitable safe work proceduresChemical emergency procedures
22Create a system of continuous improvement: Module 1 - Step 6: Evaluation and integration into the company structureCreate a system of continuous improvement:evaluate the actions undertaken to determine if the set objectives were achievedcommunicate and reward resultsmonitor results to ensure that improvements are maintainedestablish new targets and areas for action in order to make further improvements in the company’s operations.
24Module 2 - Step 1: Fact finding/inventory of chemicals
25Module 2 - Step 2: Risk and cost assessment Obtaining R and S – Phrases:Take them from a GHS compliant MSDS orIf not available you can find them for most commonly used chemicals on International Chemical Safety Cards:
35Module 2 - Step 3: Analysis of causes Firstly, identify the most costly and most hazardous chemical substances as well as the most dangerous situations occurring in your company.Then ask:Is too much of the substance kept at once in stock?How are substances spilled and wasted in the production process?Are there different forms of this substance (e.g. granular or liquid instead of fine powder) on the market which are less hazardous?
36Module 2 - Step 4: Development of measures Do the simple things first:Minimise the number of workers exposedMinimise the duration and intensity of exposureReduce the quantity of chemical agentsAppropriate hygiene measures
37Module 2 - Step 4: Development of measures Compare existing controls against those recommended by your analysisDetermine how your workplace can be modified to implement the recommended controlsBring in specialists to develop specific recommendations for substances that require Control Approach 4 or Special Control Measures for skin.
38Module 2 - Step 4: Development of measures Require eye protection if there is any danger from splashing chemicals or flying particles or if MSDS has the R phrases R 36, R 41, R 34 and/or R 35Require RPE if recommended controls are Control Band 2, 3 or 4 and the control is not available.
39Module 2 - Step 5: Action/Implementation of measures
40Create a system of continuous improvement: Module 2 - Step 6: Evaluation and integration into the company structureCreate a system of continuous improvement:Evaluate the actions undertaken to determine if the set objectives were achievedUse list of chemical substances to consider how your entire operating context and production process could be improvedFind cheaper and safer alternatives
