What is Control Banding The International Chemical Control Kit GHS and Control Banding

Control banding addresses a Control banding addresses a problemproblem 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
21/04/23Pavan Baichoo, SafeWork, ILO Geneva
Control banding takes a pragmatic approachControl 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)
21/04/23Pavan Baichoo, SafeWork, ILO Geneva
Control banding has 3 elementsControl banding has 3 elements
Hazard Risk of exposure Control measures
Called control banding because these are grouped into bands
21/04/23Pavan Baichoo, SafeWork, ILO Geneva
Hazard & risk uses available Hazard & risk uses available informationinformation 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)
21/04/23Pavan Baichoo, SafeWork, ILO Geneva
Limited number of control Limited number of control measuresmeasures Employ good industrial hygiene practice Engineering control e.g. local exhaust
ventilation Enclose the process Seek the advice of a specialist

International Chemical Control ToolkitInternational 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
21/04/23Pavan Baichoo, SafeWork, ILO Geneva
ScopeScope
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

Five stages:
Hazard classification Scale of use Ability to become airborne Finding the control approach Finding the task-specific control guidance

Hazard classificationHazard 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

Ability to become airborneAbility 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

Selection of control approachSelection 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
