GH systems

Although the GHS system is unlikely to come into force in the EU until after 200812, at which point it will be progressively phased-in, the general principles for classification and labelling follow the current EU scheme. Under GHS, each hazard category shown in Table 2.1 can be subdivided in various ways, for instance ... 

In a similar fashion to the classical GH system, gplSO cytokines mediate the assembly of higher-order signaling complexes through distinct epitopes. The sites I and II, originally identified in GH, formed by distinct helical faces of the four-helix bundle are conserved in the gplSO cytokines. In addition, gplSO cytokines also include a third epitope, termed site III,... 

Substances with fl.p. > 55°C should be regarded as combustible if brought to a high temperature. By 2015 the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS) will replace these categories. The GHS system divides flammable liquids into four new categories ... 

The Guide R2.2.1766-03 (2003) that addresses principles and criteria of occupational risk assessment for workers health introduces the weight of evidence criteria (known, presumed, suspected) according to GHS system (UN, 2003). 

In the United States, the OSHA has revised its HCS so as to be in ahgnment with the GHS system. The HCS will be fully implemented in 2016. 

By determining a chemical s hazard class and category, the hazard information that must be provided on the SDS and on the container label is pre-determined by the GHS system. 

Use of precautionary statements, while optional in the GHS system, are mandatory in OSHA s HazCom standard. 

Note Employees must also be trained on the March 26, 2012, changes to the Hazcom standard. These changes incorporate the GHS system of classification and labeling of chemicals. In particular, employees must be trained on the new pictograms, labels, and safety data sheets, by Dec. 1,2013. 

Although not obvious Irom Table 6.2.1.1, it is convenient to separate the first hazard class of acute toxicity from all of the others since it is the only class for which it is fairly easy to find data about the effect of exposures. It is possible to locate LD50 (ingestion) and LC50 (inhalation) values. (See Section 3.2.2.) Somewhat less common, but still available, are LD50 values for dermal exposure. In order that you can examine these kinds of data using the GHS system, we include three separate tables (Tables 6.2.1.2, 6.2.1.3, and 6.2.1.4) for these three modes of exposure regarding acute toxicity. We discuss these tables more below. 

The EU-GHS system which is mandatory for labelling since 2010 [9] contains H(azard)-statements which relate to aquatic environmental dangers ... 

Chairman Rafael Moure-Eraso said that including an unclassified hazards category in the Final Rule substantially improves the ability of the GHS system to provide crucial information to workers and employers about serious hazards that might otherwise not be included in safety data sheets because they do not fit into the current classifica-... 

If the scale is used with the API Rapid GH system to prepare the bacterial inoculum, it is best to make McFarland Scale 1 to 4 in order to compare densities of the inoculum and determine the specific dilutions required. 

On March 26, 2012, OSHA released revisions to the Hazcom requirements. These revisions incorporate the GHS system. The following FAQs are based on the revised requirements.
