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


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)


Control banding has 3 elementsControl banding has 3 elements

Hazard Risk of exposure Control measures

Called control banding because these are grouped into bands


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)


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


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


Toolkit operationToolkit operation

Five stages:

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

sheet(s)


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



Scale of useScale of use

Determines how much is used/handled

Quantity Solid Liquid

Weight Typically received in

Volume Typically received in

Small Grams Packets or bottles Millilitres Bottles

Medium Kilograms Kegs or drums Litres Drums

Large Tonnes Bulk Cubic metres

Bulk


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
