1. Driver Product & Safety Training MDI / TDI Bulk Liquid Transportation Revision March 2012

2. Driver Training MDI / TDI Company [name] Location [place] Date 04/01/2020 Trainer [name]

3. Background • MDI / TDI can be handled safely and are in widespread use across the world. • This programme helps in the safe transport of these chemicals by ensuringproper training of drivers • The training package is a joint effort of ISOPA and the carriers based on practical experience. • Drivers who successfully complete the driver training are issued with a MDI / TDI Driver Training Card

4. Introduction ISOPA • European ISOcyanateProducers Association • See website www.isopa.org • Member companies: olyol

6. Applications Polyurethanes are used in many products and articles: • Car seats, Steering wheels • Sports shoes • Sofas, Chairs and Mattresses • Fibre board (MDF) • Expansion joints & Gasket seals • Insulation foam (refrigerators, tanks, buildings) • Coatings, Paints • ...and many more

7. Appearance

8. Maximum Allowable Concentration (MAC) MAC : 5.0 – 10.0 ppb Odour threshold : 0.2 – 0.4 ppm Therefore: • When you smell it, it’s above the limit ! • No used PPE in the cabin

9. Main Physical and Chemical Properties (1) • Vapour pressure: Dangers of MDI and TDI are of the same magnitude but… vapour pressure of TDI is much higher (20x), therefore the RISKS of TDI are much bigger • Vapour density = 6× Air density i.e. the vapours are heavier than air!

10. Main Physical and Chemical Properties (2) • Density range 1.20 – 1.29(For TDI filling degree conform ADR  see next slide) • Important temperatures: • Crystallization starts at ± 15°C (product temp.) • Melting when reheated to ± 45°C (product temp.)

11. Degree of Filling for TDI ADR 4.3.2.2 Degree of filling 4.3.2.2.4 “Where shells are not divided by partitions or surge plates into sections of not more than 7,500 litres capacity, they shall be filled to not less than 80% or not more than 20% of their capacity”. NOT OK ±95% OK TDI / MDI* 80% NOT OK 20% OK *) For MDI there is no legal requirement but most producers follow the same rules as for TDI 11

12. Main Physical and Chemical Properties (3) MDI / TDI reacts with water (including air!) • Temperatureand pressure (CO2 release) goes up significantly in transit without external heating • Possible water sources can be: • Tank cleaning operations • Opening manlids • for: sampling, discharge etc. • by: customs, customers, drivers etc. • Non-dried air from customer’s installation • Silica gel filter malfunction

13. Effect of MDI/TDI on your Health Short term / one-off exposure above safe level • Irritates mouth, throat, lungs • Tight chest, coughing • Difficulty in breathing • Eyes watering • Itching, red skin (immediately or delayed) • May be hot or burn Symptoms can occur up to 24hrs after exposure Do not try to hide problems ! Seek medical assistance immediately !

14. Effect of MDI/TDI on your Health Long term/repeated over- exposure from breathing or skin contact leads to risk of sensitisation Symptoms such as occasional breathing difficulties similar to asthma, hay fever, sneezing When sensitised, potentially severe asthma in the case of even low MDI/TDI exposure Sensitisation will prevent working with isocyanates for life Sensitisation is non-reversible and is a reaction of the immune system. Not to be confused with irritation

15. Product Hazards: TDI • Very toxic by inhalation • Irritating to eyes, respiratory system and skin • Risk of sensitisation by inhalation andskin contact • Warning: • This effect can be delayed for as long as 24 hours after exposure! • Sensitisation means build up of irreversible allergic reactions

16. Product Hazards: MDI • Harmful by inhalation • Irritating to eyes, respiratory system and skin • Risk of sensitisation by inhalation andskin contact • Warning: • This effect can be delayed for as long as 24 hours after exposure! • Sensitisation means build up of irreversible allergic reactions

17. 60 2078 Classification and Placarding

18. Personal Protective Equipment– MDI As a minimum... • Hard hat • Goggles • Liquid-tight gloves • Safety shoes / boots • Overall • Eyewash bottle • Butyl rubber • Neoprene • Nitrile rubber

19. Personal Protective Equipment – TDI Filter use max. 8 hours Discard 24h after opening As a minimum... • Hard hat • Full face mask(with appropriate filter) • Liquid-tight gloves • Safety shoes / boots • Full chemical suit • Eyewash bottle • Butyl rubber • Neoprene • Nitrile rubber

20. Health Effects – Contact Lenses You should not use contact lenseswhen handling isocyanates When eye contamination you will not be able to remove the lenses as they will stick to the eye surface due to reaction between the lenses and the eye and water layer between them.

21. Personal Health (1) • Use an appropriate cartridge / canister(min. AP2) for maximum 8 hours and throw it out 24 hours after the seal has been broken

22. Personal Health(2) • Wash hands (& face) before eating, drinking, smoking or going to the toilet • Keep contaminated PPE out of the cabin • A quantity of vapour equal to the size of a one Eurocent coin is enough to increase the concentration in the average cabin well above the MAC value • Imagine working / sleeping in this atmosphere for 8 hours !

23. Product Quality Control • Certificate of Analysis (CoA) • Samples (Not recommended) • CoA is strongly preferred to a sample • Drivers should not take samples ! • Never take a sample in your cab !!!Not even for 1 minute !!! • Temperature(Customer specific)

24. Site Safety Make yourself familiar with the site emergency policy and location of following items: • Signs & Alarms • Wind direction indicator • Emergency stop button • Emergency shower • Assembly point • Waste bin (for used gaskets, gloves, etc.) • Decontamination & Absorption material

25. Spill Handling (by Emergency Services) Always wear PPE !! • Drivers should observe from a safe distance and remain available to provide information • Emergency services should: 1. Cover sewer system 2. Absorb the spill 3. Neutralise 4. Wait (30–60 minutes after reaction has finished) 5. Remove spill after reaction has finished. 6. Put residues in designated chemicals waste bin 7. Apply decontamination fluid

26. Loading: Key Items • PPE must be worn • Tank equipment • 3-Minutes check before & after loading

27. Text under construction Fall protection (1) 27

28. Text under construction Fall protection (2) 28

29. Tank Equipment • Manlid must be kept closed! (moisture prevention) • Ensure customs letter (if applicable) is present • Do not mix-up the vapour return and liquid line !!! • Tank depressurised? • Cleaned tanks must be dry ! • Capacity (keep filling degree in mind!)

30. 3-Minutes Check before Loading Equipment • Tanker exterior clean? • Spillage tray clean? • Tanker correctly labelled and placarded? • All valves closed? • Manlid closed and bolts tightened? • Check temperature

32. Transport • Hours / Speed • Check temperature (and pressure) • Reporting unsafe conditions / incidents • Parking

33. Opening of Tanks in Transit by Customs Officials • Tanks should not be opened whilst in transit because of the dangers to human health • ISOPA issued a letter to Customs Officials explaining thereasons why • Letter is available in 14 languages i.e. CZ - DE - EN - ES - FR - HU - IT - LV - PL - RO - RU - SK - TUR - UA • Letter can be downloaded from the ISOPA website http://www.isopa.org/isopa/index.php?page=logistics-ehs 33

34. Security en Route What to do & not to do: • Do not leave the vehicle unlocked • Do not disclose information about product carried, customer, route or destination • Park preferably on secure parking areas

35. Heating All methods: • Maximum product contact temperature = 60°C • Do-not-open-the-manlid Steam: • Only external steam coils • Maximum 1.7 bar(= ~ 115 °C)

36. Unloading: Key Points (1) • Follow site regulations • Behaviour  You are the supplier’s representative • Know the operational responsibilities between operator and driver as described in the CEFIC / ECTA Behaviour Based Safety Guidelines • Report unsafe conditions at customers (including near misses)

37. Unloading: Key Points (2) • Storage tank capacity • communication driver / operator • PPE must be worn • Observe connections, pressure during unloading • Samples(Report back if you have to take a sample) • Unloading methods(Details on next slides)

38. Discharge Methods (1)Customer liquid pump and vapour return Preferred option! (with hoses provided by customer, if possible)

39. Discharge Methods (2)Customer nitrogen or dry air

40. Discharge Methods (3a)Vehicle compressor with silica gel

41. Discharge Methods (3b)Vehicle compressor without silica gel

42. SpillageTray Lay-out (example) Liquid line and vapour return line should be properly identified

43. 3-Minutes Check after Discharge (1) Equipment • Disconnected? • Free of spillages including spillage tray? • Safety handrail down? • Valves closed and blind-flanged, manlids closed? • Spillage tray covers closed? • Only slight overpressure (max 0.1 bar)? • Depressurise at the customer if possible, or inform planner Documentation(1) • Handed to the customer? • Transport documentation signed?

44. 3-Minutes Check after Discharge (2) Documentation (2) • Customer needs: • Copy of transport document signed by driver & customer • Certificate of Analysis • Driver keeps: • Copy of transport document signed by driver & customer For TDI:Obtain or make transport document reading: Empty tank container*), last load: UN 2078 Toluene Diisocyanate, 6.1, II (D/E) *)or: tank vehicle; demountable tank; portable tank

45. Near Misses & Unsafe Conditions Iceberg Theory Incidents Near misses & Unsafe conditions

46. Near misses and unsafe conditions Reporting examples Active near miss reporting will reduce / avoid serious incidents: • Road traffic incidents • Equipment failures • Incorrect human behaviour • Overflows • Overpressure • Spills • Unexpected temperature rise (check regularly!) • Unsafe working conditions (missing safety shower etc.) • Unsecure routing

47. Incidents • Statistics indicate: • More than 80% of all incidents are related to human behaviour • Most incidents and accidents occur during loading & unloading So THIS is your Challenge: You are the most important safety factor (OR you will be the most important risk factor !)

48. Emergency ResponseKnow First Aid for MDI /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 • Immediately remove contaminated clothing • Immediately wash, wash, wash with soap & water • Go outside into fresh air • Doctor must be called or patient taken to medical facility • Inform supplier – who can provide supporting information

49. Emergency ProceduresExposure to MDI / TDI • A single high exposure to MDI / TDI is one possible cause of sensitisation • Early treatment is important • Remember that symptoms may occur later • Help is available for the doctor from ISOPA member companies • Speed is essential • Practice First Aid procedures • Seek medical advice 49
