1 1 |1 | Control banding & International Chemical Control Toolkit

2 2 |2 | 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 & monitoring equipment may be limited

3 3 |3 | Control Banding takes 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)

4 4 |4 | Control banding has 3 elements 1.Hazard 2.Risk of exposure 3.Control measures Called control banding because these are grouped into bands

5 5 |5 | Hazard & risk uses readily available information Hazard – use existing hazard assessment e.g. EU Risk (R) phrases, GHS classification –From safety data sheet, International Chemical Safety Card Risk based on: –Amount of chemical used –Ability to become airborne Volatility (liquids) or likelihood of dust generation (solids)

6 6 |6 | 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

7 7 |7 | International Chemical Control Toolkit Provides simple means for applying the control banding principles Step by step process leading to standard task guidance information Modelled on COSHH Essentials Developed for ILO by team of occupational hygienists assembled by IOHA Further developed by International Technical Group –coordinated by International Programme on Chemical Safety

8 8 |8 | Toolkit leads from hazard to work practice guidance 1.Hazard classification 2.Scale of use 3.Ability to become airborne 4.Finding the control approach 5.Finding the task-specific control guidance sheet(s)

9 9 |9 | 1. Hazard classification Based on R phrase or GHS classification 6 hazard groups: (A-E inhalation, S – skin contact) Reference table allows hazard group to be assigned to the chemical

11 11 | 2. Scale of use Consider amount of chemical used in a batch or day

12 12 | 3. Ability to become airborne Solids –Low: pellets –Medium: crystalline solid –High: fine powders Liquids – based on boiling point –Low: BP>150° C –Medium: BP 50 – 150° C –High: BP >50° C Process temperature

13 13 | 4. Select control approach High dustiness / volatility Medium dustiness Medium volatility Low dustiness / volatility Amount used Hazard Group A 1111Small 2111Medium 2211Large Hazard Group B 1111Small 2221Medium 3321Large

14 14 | 5. Find task-specific control guidance sheet Task control sheetTask description Control approach 1 100General principles 101Sack, bottle & drum storage 102Bulk storage 103Removing waste from air cleaning unit

15 15 | Special cases Additional guidance sheets for chemicals that: –are absorbed by, or harmful to, skin –Require respiratory protection Special guidance sheets for pesticides – don't use step by step process
