2 Skin corrosion/irritation - - - - - -
3 Serious eye damage/eye irritation Category 2A Warning H319: Causes serious eye irritation P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing.
P337+P313: If eye irritation persists: Get medical advice/attention.
P264: Wash ... thoroughly after handling.
P280: Wear protective gloves/protective clothing/eye protection/face protection. 		It is not essential to classified finely the substance which is equivalent to "Category 2" into "Category 2A (irritation)"or "Category 2B (mild irritation)" in the U.N. GHS document 3.3.2.9. However, it is indicated that "40mg of application to a rabbit indicates severe eye irritation" in ACGIH which was considered to be the basis of three-ministry GHS classification. Therefore, it will be appropriate to classify finely from "Category 2" to "Category 2A" for correction.
