A4.3.11.14.2 It is necessary to consider whether the concentration of each ingredient is sufficient to contribute to the overall health effects of the mixture. The information on toxic effects should be presented for each ingredient, except

At standard temperature and pressure, oxyhydrogen can burn when it is between about 4 and 95 hydrogen by volume.

Information to support negative test results should be provided (e.g. carcinogenicity studies in the rat have shown no significant increase in the incidence of cancer ).

(b) if it is unlikely that these effects will occur at the concentrations present. For example, when a mild irritant is diluted in a non irritating solution, there comes a point where the overall mixture would be unlikely to cause irritation

(c) remove contaminated clothing and protective equipment before entering eating areas .

Provide information on the dose, concentration or conditions of exposure that may cause adverse health effects. Where appropriate, doses should be linked to symptoms and effects, including the period of exposure likely to cause harm.

If data for any of these hazards are not available, they should still be listed on the SDS with a statement that data are not available.

When either of the gases are mixed in excess of this ratio, or when mixed with an inert gas like nitrogen, the heat must spread throughout a greater quantity of matter and the temperature will be lower.

(a) maintain air concentrations below occupational exposure standards , using engineering controls if necessary

I like to think of this as the Atari Pong of this blended reality play.

A4.3.11.3 The health effects included in the SDS should be consistent with those described in the studies used for the classification of the substance or mixture.

A scrambled egg is mush tasty mush but it's mush.

(c) Predicting the interactions between ingredients is extremely difficult, and where information on interactions is not available, assumptions should not be made and instead the health effects of each ingredient should be listed separately.

A4.3.11.4 General statements such as Toxic with no supporting data or Safe if properly used are not acceptable as they may be misleading and do not provide a description of health effects. Phrases such as not applicable , not relevant , or leaving blank spaces in the health effects section can lead to confusion and misunderstanding and should not be used.

3.10.1.6.3 The classification criteria refer to kinematic viscosity. The following provides the conversion between dynamic and kinematic viscosity

The toxicological data should describe the mixture. If that information is not available, the classification under GHS and the toxicological properties of the hazardous ingredients should be provided.

In effect, it indicates the ease or difficulty of using distillation to separate the more volatile components from the less volatile components in a mixture.

So we've been exploring a lot of ideas in telepresence and mixed reality to literally allow kids to project their ideas into this space where other kids can interact with them and build upon them.

A4.3.11.6 Also provide information on the relevant negative data (See A4.2.2.3).

For health effects where information is not available, this should be clearly stated. Health effects should be described accurately and relevant distinctions made. For example, allergic contact dermatitis and irritant contact dermatitis should be distinguished from each other.

Causes damage to organs (or state all organs affected, if known) (state route of exposure if it is conclusively proven that no other routes of exposure cause the hazard) .

A popular food item, the breakfast burrito, draws from all three, having a soft flour tortilla wrapped around bacon and scrambled eggs or other hot, cooked fillings.

So we've been exploring a lot of ideas in telepresence and mixed reality to literally allow kids to project their ideas into this space where other kids can interact with them and build upon them.

3.10.3.2.1 Where the mixture itself has not been tested to determine its aspiration toxicity, but there are sufficient data on the individual ingredients and similar tested mixtures to adequately characterize the hazard of the mixture, these data can be used in accordance with the following bridging principles.

A2.24 b) Under Hazard category , replace Special category with Additional category for effects on or via lactation and, under Criteria , add the following sentence after the current text or, mixtures containing 0.1 or 0.3 of such a substance (see notes 1 and 2 of Table 3.7.1, Chapter 3.7). .

A4.3.12.1 Provide information to evaluate the environmental impact of the substance or mixture if it were released to the environment. This information can assist in handling spills, and evaluating waste treatment practices and should clearly indicate species, media, units, test duration and test conditions. Where information is not available this should be stated. Provide also a short summary of the data given under A4.3.12.3 to A4.3.12.7.

Information on toxicity can be provided using data from tests performed on aquatic and or terrestrial organisms. This should include relevant available data on both acute and chronic aquatic toxicity for fish, crustaceans, algae and other aquatic plants. In addition, toxicity data on other organisms (including soil micro and macro organisms) such as birds, bees and plants, should be included when available.

A4.3.12.2 Some ecotoxicological properties are substance specific, i.e. bioaccumulation, persistence and degradability. The information should therefore be given, where available and appropriate, for each substance of the mixture.

Bioaccumulation is the potential for the substance or certain constituents of a mixture to accumulate in biota and, possibly, pass through the food chain. Test results relevant to assess the bioaccumulative potential should be given. This should include reference to the octanol water partition coefficient (Kow) and bioconcentration factor (BCF), if available.
