The most significant change is, that in most cases the classification criteria of the new regulation have become much more stricter. Usually, mixtures are classified based on the hazards of their ingredients. Regarding water-miscible cooling lubricants, for example, emulsifiers, solubilising agents or biocides are often irritating. According to the former Dangerous Preparations Directive, a mixture consisting of 20% skin irritating ingredients had to be classified itself as skin irritating, now, according to the CLP Regulation, the limit is lowered to 10%.
As a consequence, many cooling lubricant concentrates being hazard-free according to the former directive, might now be classified otherwise, e.g. as skin or eye irritating, but without any changes regarding the real danger.
Especially noticeable is the new appearance of the hazard pictograms: Before, an orange box with a black border standing on the edge, now, a square with a red border standing on one tip (see below). Most of the symbols remain, but the St. Andrew’s cross is replaced by an exclamation mark. There are two completely new pictograms: The gas cylinder and the human silhouette signalising particular health hazards.
By implementing the CLP Regulation, new hazard classes are introduced as well, among them eight new physical hazards such as corrosive to metals and a new health hazard called specific target organ toxicity (STOT).
For hazard classes such as “skin irritation” applies, that it can occur in different states of intensity. This intensity is divided into various categories. The lower the number, the more severe the hazard. In this example, category 1 represents severe skin corrosion (Skin corrosion 1) and category 2 represents skin irritation (Skin irritation 2).
Furthermore, H- and P-statements replace the R- and S-phrases as verbal descriptions of hazards and hazard minimization. Here, there are principally many overlaps, for example: Before: R38 – Irritatin to skin. S24 – Avoid contact with skin. Now: H315 – Causes skin irritation. P262 - Do not get in eyes, on skin, or on clothing.
In addition, there are two new signal words “Warning” and “Danger”, which represent less severe respectively more severe hazards.
