Again Sensitivity is a theme we keep returning to, because in our recent international travels we have both independently noticed there is little appreciation of this phenomenon worldwide. Also, as noted last issue, even our leading lights don t quite get the message, so until we see this clearly spelled out in literature, course syllabus' and store precautions, we are going to continue to harp on it.
Sensitization is different from irritation and toxicity.
Many of these substances have achieved notoriety via RIFM monographs. However it is true to say that in the past many irritants may have been classified and senstizers and mild sensitisers may have been grouped with moderate or severe sensitisers. In addition, anything can become a sensitizer, especially with undiluted or prolonged use. We may see some professional organisations revising these lists soon. Please note also these lists are an expression of hazard potential, as determined by predictive tests.
