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

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

Appearance

BrownCrusty
TDI Clear to pale yellowSharp, pungent

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
Version March 2012

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!
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.)

Degree of Filling for TDI
*) For MDI there is no legal requirement but most producers follow the same rules as for TDI

Version March 2012 12
Main Physical and Chemical Properties (3)
MDI / TDI reacts with water (including air!)
Temperature and 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
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 tohide problems !Seek medical assistance
immediately !
Version March 2012
14
Long term/repeated over- exposure from breathing or skincontact 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 ofeven low MDI/TDI exposure
Sensitisation will prevent working with isocyanates for life
Sensitisation is non-reversible and is a reaction of theimmune system. Not to be confused with irritation
Effect of MDI/TDI on your Health
Version March 2012
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
Version March 2012
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

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 w

Version March 2012 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
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)
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 !!!

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
Version March 2012
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

Near misses & Unsafe conditions
Incidents
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
Version March 2012

Incidents
So THIS is your Challenge:
You are the most importantsafety 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 !)

Emergency ResponseKnow 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
Version March 2012
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
