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

2 Version March 2012 2 Driver Training MDI / TDI Company [name] Location [place] Date 12/06/2014 Trainer [name]

3 Version March 2012 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 ensuring proper 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 Version March 2012 4 European ISO cyanate P roducers A ssociation See website www.isopa.org Member companies: Introduction ISOPA olyol

5 Version March 2012 5

6 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 Version March 2012 7 Appearance LiquidReacted MDIClear to brown Slightly musty Brown Crusty TDIClear to pale yellow Sharp, pungent White Foamy

8 Version March 2012 8 Maximum Allowable Concentration (MAC) MAC: 5.0 – 10.0 ppb Odour threshold: 0.2 – 0.4 ppm Therefore: When you smell it, its above the limit ! No used PPE in the cabin

9 Version March 2012 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 Version March 2012 10 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.) Main Physical and Chemical Properties (2)

11 Version March 2012 TDI / MDI* 20% 80% ±95% OK NOT OK OK NOT OK 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. Degree of Filling for TDI *) For MDI there is no legal requirement but most producers follow the same rules as for TDI 11

12 Version March 2012 12 Main Physical and Chemical Properties (3) MDI / TDI reacts with water (including air!) Temperature and pressure (CO 2 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 customers installation Silica gel filter malfunction

13 Version March 2012 Effect of MDI/TDI on your Health 13 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 Version March 2012 14 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 Effect of MDI/TDI on your Health

15 Version March 2012 15 Product Hazards: TDI Very toxic by inhalation Irritating to eyes, respiratory system and skin Risk of sensitisation by inhalation and skin contact Warning: This effect can be delayed for as long as 24 hours after exposure! Sensitisation means build up of irreversible allergic reactions

16 Version March 2012 16 Product Hazards: MDI Harmful by inhalation Irritating to eyes, respiratory system and skin Risk of sensitisation by inhalation and skin contact Warning: This effect can be delayed for as long as 24 hours after exposure! Sensitisation means build up of irreversible allergic reactions

17 Version March 2012 17 Classification and Placarding ProductTransportUse MDINot regulated but still harmful TDIADR / RID / IMDG UN 2078 Class 6.1 Packing Group II Marking and Labelling: ADR tunnel category : (D/E) 60 2078

18 Version March 2012 18 Hard hat Goggles Liquid-tight gloves Safety shoes / boots Overall Eyewash bottle Personal Protective Equipment – MDI As a minimum... Butyl rubber Neoprene Nitrile rubber

19 Version March 2012 19 Hard hat Full face mask (with appropriate filter) Liquid-tight gloves Safety shoes / boots Full chemical suit Eyewash bottle As a minimum... Filter use max. 8 hours Discard 24h after opening Personal Protective Equipment – TDI Butyl rubber Neoprene Nitrile rubber

20 Version March 2012 20 Health Effects – Contact Lenses 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. You should not use contact lenses when handling isocyanates You should not use contact lenses when handling isocyanates

21 Version March 2012 21 Personal Health (1) Use an appropriate cartridge / canister (min. AP 2 ) for maximum 8 hours and throw it out 24 hours after the seal has been broken

22 Version March 2012 22 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 ! Personal Health (2)

23 Version March 2012 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)

45 Version March 2012 45 Near Misses & Unsafe Conditions Iceberg Theory Near misses & Unsafe conditions Incidents

46 Version March 2012 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 Version March 2012 47 Incidents So THIS is your Challenge: You are the most important safety factor Statistics indicate: More than 80% of all incidents are related to human behaviour Most incidents and accidents occur during loading & unloading (OR you will be the most important risk factor ! )

48 Version March 2012 Emergency Response Know First Aid for MDI /TDI 48 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 Version March 2012 Emergency Procedures Exposure 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
