Thanks Chris for the very detailed response.
It goes without saying health surveillance is based around findings.
In future I will be more careful with my wording as my comment was more to answer her question that it should be done and at minimum it should at least annually and of course dependent upon risk etc. etc.
Have fun on your hols.

Subject: Re: [OCC-HEALTH] skin health surveiliance
I have to disagree with Janet. I would certainly not consider an annual paper screen as being adequate. Given the nature of the exposures the cumulative sub-clinical damage that causes irritant contact dermatitis could result in the appearance of this condition at any time. The sub-clinical damage cannot be detected by visual or paper screening. The sub-clinical damage also predisposes to allergic contact dermatitis. It can be detected by skin hydration measurement.
"Nevertheless, changes in stratum corneum hydration measured by electrical methods can be predictive of the irritation potential of topically applied compounds. Indeed, subclinical irritant dermatitis can be detected by early changes (reduction) in stratum corneum hydration." - From: The Potential Use of Non-Invasive Methods in the Safety Assessment of Cosmetic Products - Report and Recommendations - ECVAM Workshop 36. (European Centre for the Validation of Alternative Methods)
The methods used and frequency of surveillance needs to be adjusted to the particular workplace situation and potential for skin damage as determined during the risk assessment for each task. I usually recommend an initial screening, then, based on the results, a decision as to frequency can be made. Eventually, depending upon results, it may be possible to extend the interval for specific workplaces and tasks.
