2. Presentation structure
What is Control Banding
The International Chemical Control Kit
GHS and Control Banding

3. Control banding addresses a problem
Many chemical hazards in the workplace
Employers need guidance on how to protect workers
OELs established for relatively few chemicals
Availability of technical expertise and monitoring equipment may be limited
Pavan Baichoo, SafeWork, ILO Geneva
20/04/2017

4. Control banding takes a pragmatic approach
Occupational risk assessment and risk management instrument
Developed by occupational hygienists and toxicologists
Uses readily available information about chemicals and the workplace, to rank hazard and assess risk
Can be used without on-site technical experts and expensive exposure measurements
Suitable for small and medium sized enterprises (SMEs)
Pavan Baichoo, SafeWork, ILO Geneva
20/04/2017

5. Control banding has 3 elements
Hazard
Risk of exposure
Control measures
Called control banding because these are grouped into bands
Pavan Baichoo, SafeWork, ILO Geneva
20/04/2017

6. Hazard & risk uses available information
To categorise hazard – use existing hazard assessment e.g. EU Risk (R) phrases, GHS classification
Risk based on:
Amount of chemical used
Likelihood that will become airborne
Volatility (liquids) or likelihood of dust generation (solids)
Pavan Baichoo, SafeWork, ILO Geneva
20/04/2017

7. Limited number of control measures
Employ good industrial hygiene practice
Engineering control e.g. local exhaust ventilation
Enclose the process
Seek the advice of a specialist

8. International Chemical Control Toolkit
Scheme for Workplace Chemicals Control Kit designed for SMEs in developing countries
Work undertaken by experts from ILO, IOHA, USA, South Africa, HSE
Provides simple means for applying the hazard and risk information to identify the control measure
Generic risk assessment based on GHS and task guidance sheets
Aim is to provide simple and practical means to prevent/reduce risks of chemicals
Pavan Baichoo, SafeWork, ILO Geneva
20/04/2017

9. Pavan Baichoo, SafeWork, ILO Geneva
Scope
Many substances used at work contain chemicals
Guidance should be provided to ensure safe handling
Does not cover process generated dusts and fumes
Based on the HSE’s COSHH Essentials kit

10. Pavan Baichoo, SafeWork, ILO Geneva
Toolkit operation
Five stages:
Hazard classification
Scale of use
Ability to become airborne
Finding the control approach
Finding the task-specific control guidance sheet(s)
Pavan Baichoo, SafeWork, ILO Geneva
20/04/2017

11. Hazard classification
Determination of hazards presented by the chemicals (based on R phrases or GHS)
6 hazard groups (A-E inhalation, S contact)
Simple 3-step reference table allows hazard group to be assigned to the chemical
Hazard groups determined for common solvents
Set of guidance sheets for pesticides

Weight
Typically received in
Volume
Small
Grams
Packets or bottles

14. Ability to become airborne
Physical form of chemical affects how likely it is to get into the air
Solids
Low: pellets
Medium: crystalline solid
High: powder
Liquids
Low: BP > 150°C
Medium: BP 50 – 150
High: BP < 50
Process temperature

15. Selection of control approach
Stages 1-3 enable the choice of control approach to be made using table
4 control approaches possible: general ventilation, engineering controls, containment and Special
Table overleaf allows for easy identification
Pavan Baichoo, SafeWork, ILO Geneva
20/04/2017

16. Control approach selection
Amount used
Low dustiness or volatility
Medium volatility
Medium dustiness
High dustiness or volatility
Hazard group A
Small 1
Medium 2
Large
Hazard group B 3
Hazard group C 4
Hazard group D
Hazard group E
For all hazard group E, substances, choose control approach 4
