Stimulating the Dialog,
and Continuous Improvement.
Resulting in Behaviour Change
End 2010, new EU legislation, REACH regulation (EC) 1907/2006 and GHS, in EU CLP regulation (EC) 1272/2008, are affecting the chemical industry bringing the need to refresh and re-address the safe use through
Walk the Talk is focusing on industrial and professional use.

There is a new dimension to the initial industry pro-active safety program „Walk the Talk“
REACH (Registration, Evaluation, Authorisation of Chemicals)
First registrations finalized by December 1st 2010 with the goal to:
Provide a high level of protection to human health and environment
Ensure high safety standards in industry
Have compliance demonstrated....“Safe Use“
Revision 2017 8

9. New regulation on Classification Labelling and Packaging (CLP)
Regulation (EC) No 1272/2008 (CLP Regulation) is the new EU legislation on classification, labelling and packaging of substances (mandatory 1 Dec 2010) and mixtures (mandatory 1 June 2015)
The UN GHS (Globally Harmonised System for Classification and Labelling of Chemicals) has been adopted through the CLP Regulation replacing the provisions of the Dangerous Substances/ Preparations Directives (DSD/DPD) which will be finally repealed by 1 June 2015
Product hazards remain the same,

11. REACH Safety Data Sheets
eSDS (extended Safety Data Sheet)
Reading the eSDS from your supplier is a MUST, because it
contains information on applications and safe handling and
how to be in regulatory compliance for REACH
Revision 2017 11

12. REACH Safety Data Sheets, eSDS
Are you in compliance?
Chapter 16 of the eSDS:
Look for the Exposure Scenario which lists your application/use
Within the Exposure Scenario review:
Process Category and Processes, tasks, activities covered
Products/article characteristics, operational conditions
Risk Management Measures
Revision 2017 12

13. How do I know, that I have a ‘Safe Use’ situation?
 Compare your own operation parameters with the eSDS of your supplier(s)
Use means:
TASK [=Exposure Scenario] x CONDITION IN WHICH TASK TAKES PLACE [Operational Conditions] = POTENTIAL EXPOSURE
The conditions of use “potential exposure in a use”.
They include:
the operational conditions (OC)
the risk management measures, (RMM), like personal protective equipment
concentration in a mixture or an article and the physical state (powder, liquid etc)
Information on the surroundings in which the substance is used
Revision 2017 13

14. You need to comply with REACH
Authorities will review REACH
implementation along the value chain
Check your operational conditions
and whether you are in Compliance:
Demonstrate safe use of your
chemicals in your particular applications.
To obtain Safe Use you need to follow the instructions in the eSDS as outlined in Section 16, within the Exposure Scenarios:

Know who to tell
And don’t panic !
Revision 2017 30 30

31. Emergency procedures: First aid TDI
Force open the eyelids
Flush with lots of water for at least 15 minutes
If in doubt, keep flushing
See eye specialist as soon as possible
Advice not to wear contact lenses, they could complicate treatment in case of emergency.
Immediately remove contaminated clothing and wash with soap & water
An diisocyanate skin decontamination study demonstrated that cleaning very soon after exposure is important, and that a polyglycol-based skin cleanser or corn oil may be more effective than soap and water
Go outside into fresh air
Doctor must be called or patient taken to medical facility
Inform supplier – who can provide supporting information

SLIDE #32
Speaking script for the TDI spillage videos – practice this section to ensure that you are in step with the video. Click on the link to start a video:
For minor spillages use solid or liquid decontaminants which can also be used to clean equipment
Major spillages of more than 2 square metres should always be dealt with by trained personnel using protective clothing and PPE including breathing apparatus
If a spillage occurs first evacuate the area and prevent further leakage or spillage
Prevent the TDI going into drains by bunding the area
Use sold decontaminant, such as sand to contain, absorb and neutralise the TDI
Materials for cleaning up spillages, including clearly labelled decontaminants must be available both inside and outside where TDI is used
Place all waste materials in drums for further decontamination
Wash the affected area with liquid decontaminant
If a spillage is inside a building test the atmosphere for TDI vapour
All waste must be disposed of in accordance with local regulations and never dispose of, even small amounts, of TDI into drains or sewers
Revision 2017 32 32

33. Emergency procedures - Exposure to TDI
In case of emergency: Immediate action is essential!
Always seek medical advice!
Practice First Aid procedures regularly!
A single high exposure to TDI is one possible cause of
sensitisation
Early treatment is important
Remember that symptoms may occur later
ISOPA member companies can provide help to the doctor
in charge.
Revision 2017 33

34. Know where to find the emergency equipment
Where is your eSDS copy ?
Decontaminant solution, see eSDS
Shovels
Brushes and waste container
Absorbent material such as sand
Revision 2017 34 34

35. Dealing with a spillage of TDI
Clear immediate area
Small Spillage – area less than about 2m2
Evacuate, call the emergency services
Put on PPE including respirator
Seal spill area with eg. Sandbags, rubber mats, wood chips/fibers, foam dust.
Cover with fire extinguishing foam or sand to prevent escape of TDI vapours
Large Spillage – area more than about 2m2
Prevent TDI entering drains
Control spill with wet sand absorbent
Put contaminated sand in steel drums (max 2/3 full) and leave open to prevent pressure build up
Treat as TDI waste
All Spillages
Revision 2017 35 35

36. Dealing with a spillage of TDI
Video Clip:

SLIDE #36
Speaking script for the TDI spillage video – practice this section to ensure that you are in step with the video. Click in green area to start video:
Most incidents with isocyanate fall under the category “spillage”
In case of a leaking container or any other spillage, please stop isocyanates from entering drains.
To clean an isocyanate spillage you may use a special absorbent or simple sand. As the vapour pressure curve suggested, spillages can cause critical emissions. Do wear respiratory equipment.
Alternatively you may use foam to cover the spillage. Foam contains moisture. Due to chemical as well as physical properties, the isocyanate vapor pressure will be significantly reduced.
Water or any residual moisture reacts with isocyanate. This reaction may continue in the disposal drums. Therefore drums should only be filled up for ¾. Do not seal the disposal drums, allow internal pressure to be released.
