Has anyone had to provide advice on exclusion of isocyanate paint/adhesive from any offshore facility. what alternative steps/products have you adopted based on experience? all comments and advice please.

I would be interested to know what reason is being given for the exclusion of isocyanate based products.

Perhaps they are worried if a pre-sensitised individual is exposed to 1part per billion of the isocyanate they could die from anaphalaxis?
Or perhaps they are worried that when it comes to removal of the material (if heating is involved) there will again be potential exposures to isocyanate? even though the material has curred.
Or perhaps they are concerned that there will be additional requiresments for health surveilance (respirometry) if they are to use asthma causing agents if this is not currently required.
Or perhaps they are just looking at this from a control perspective where all reasonable effort should be made in line with the hierarchy of control to replace any harmful substances where possible with less or non-harmful equivalents.

Contact your current supplier of the isocycnate paint & adhesive products and ask that what alternatives they have in their product range . Almost all suppliers have a portfolio of technologies. They can supply the same colours or adhesive properties in different formulations & chemistry technology. Two pack paints are very resilient and once applied have reacted the isocycanate away. Providing the painter is properly trained with suitable ppe, there is no issue.
I'm a Bit more worried about hydrocarbon leaks than isocyconate paint
Heaps of advice on HSE Coshh web site.

Historically I remember that this type of paint is extensively used in the offshore industry, especially on drilling units.
I would suggest you look at both method of application, who may become in contact or potentially affected, system to apply the paint without affecting anyone etc.
If you can ensure good controls are in place then would be very helpful, also discuss with the manufacturer as to good practices and also possible alternatives?

thanks everyone. this relates actually to potential exposure when using the adhesives and paints during maintenance activities. i reckon amount relates to the quantity being used which determines the levels of control being implemented?. thoughts?

I reckon the level of control is dependant upon the hazard / risk, which will be determined by your COSHH assessment.
Your COSHH will take into account the Conc. in the material, quantity being used, area being used in, method of application etc... and determine the correct level of control.
Remember that the legal exposure limits for isocyanate are very small, there will also be issues with atopic or asthmatic individuals not only working with but in the vacinity of this application. Dont forget COSHH covers medical requirements, health surveilance and where necessary exposure monitoring too.

It isn't really the quantity being used that is the key question, more the actual, or potential, exposure. Keep in mind that isocyanates are both respiratory and skin sensitisers and that evidence now exists that skin exposure can lead to respiratory responses.
Exposure will depend upon a number of factors, including bioavailability, i.e. is it in a form where it can be inhaled/absorbed into the skin?
So the risk assessment will be concerned with how it is used and what exposure might occur. Used correctly so that exposure is adequately controlled and the risk can be very low. However, as a basic rule, my experience is that whenever isocyanates are being used, the HSE will expect health surveillance in the form of biological monitoring (i.e. identification from urine samples).
