Prevent or control exposure to the hazardous substances to as low a level as is reasonably practicable. What this means to you. Hazard sensitiser. A chemical that can cause an allergic reaction in the airways following CLP –

A chemical substance will be classified as a skin sensitizer if there is reliable human evidence or positive results from an appropriate animal test. A respiratory sensitiser is a substance which, when it is breathed in, can lead to occupational asthma, which is an allergic reaction in the lungs.

Substances can be classified as skin sensitisers if there is evidence from experimental tests or in humans that the substance can lead to sensitisation by skin contact. From information in the Classification and Labelling Inventory, there are over 14 000 substances on the EU market with some indication of a skin sensitising concern.

CONSIDERATIONS 3. The purpose of the harmonised criteria for classification of respiratory and skin sensitisers is Definition - What does Sensitizer mean? Sensitizers are chemical substances that can cause sensitization in the lungs (respiratory sensitizers) or to the skin (skin sensitizers) after exposure. Once individuals are sensitized, they can have severe reactions to further exposure, even if the exposure quantity is below the regulated occupational exposure limits. Medical definition of sensitizer: one that sensitizes: as.

The agents at risk of being skin sensitisers should be known and the exposure amount assessed. Some chemical skin sensitisers are classified and listed in EU regulations. They are labelled (1) with R-phrases R 43 “May cause Skin sensitizer means a chemical that will lead to an allergic response following skin contact. (See Appendix A to 29 CFR 1910.1200, section A.4.)

Introduction. Identification or categorization of sensitizing chemicals to skin is an important process in chemical risk assessment. Current classifications of skin sensitizers have mostly been achieved using the mouse local lymph node assay (LLNA) and guinea pig tests, including the Buehler test or guinea pig maximization test (GPMT) (Kimber et al., 1995, Kimber and Weisenberger, 1989 What does PTNSR mean? PTNSR as abbreviation means "Packaging and Transport of Nuclear Substances Regulations".

The authors suggested that the probable determinants of sensitization are the N(CH 3) 2 or the N(C 2 H 5) 2 moieties in the para position of the benzene ring structure and that cross-reactivity is limited to substances with amino groups substituted with at least two alkyl groups (see Figure 1).

A respiratory sensitiser is a substance which, when it is breathed in, can lead to occupational asthma, which is an allergic reaction in the lungs. Once a person has developed asthma (or has been 'sensitised'), any further exposure to the substance can produce the same reaction. You may not develop asthma immediately after working with a substance. sensitiser. In the process with HDDA it became evident that the view on how ECHA’s general approach document should be interpreted varies between member states. It also became clear that for skin sensitisers it may be difficult to provide substance-specific evidence in humans for some of the ELoC factors presented in the document.
