Danger labels

When transporting dangerous chemical substances the carrier has to affix at the rear of the vehicle and/or substance packaging plates and labels, a danger label and/or a substance number.The risk number contains at least two figures the first being the main risk, the second the secondary risk. 0 indicates the absence of a secondary risk. If the main risk number is divided into two, this indicates an aggravated risk. The numbers that are of interest here are ... 

Lastly, always follow the label. Any material sold as a crop protection chemical in the United States must be registered with the Environment Protection Agency (EPA) and labeled. The label must be followed. Failure to do so is illegal and can be dangerous. Labels list time and rate of application and the vegetables and pests on which the product can be used. They also contain other information, such as safety precautions. Always read the label and use the chemical only where and how it is permitted. It is possible to cause severe environmental or bodily injury if agricrrltural chemicals are misused. In no case does the Agricultirral Extension Service recommend the use of any plant protection substance in a marmer inconsistent with its label. 

Part III of Annex A is a listing of appendices. The most relevant of these are A. 5, general packing requirements, A.6, general conditions for the use of intermediate bulk containers (IBCs), both of which are based on the UN recommendations, and Appendix A.9, labelling requirements. The diamond shaped danger labels specified in Appendix A.9 are applied to both the package and the transport vehicle. These labels provide an instant indication of the classification of material carried and therefore an indication of the risk. All the labels used in ADR are displayed in Plate 1 (see Colour Section).

High-powered lasers or laser systems which can be hazardous to the eye from intrabeam viewing, specular reflections, or diffuse reflections. They may also be hazardous to the skin or flammable materials, causing a fire. These lasers carry a DANGER label. Strict controls are required, including use of protective eyewear and door interlocks. 

The two most important pieces of chemical control legislation enacted affecting the dye and pigment industries are the United States Toxic Substance Control Act (TSCA) and EEC s Classification, Packaging, and Labeling of Dangerous Substances and its amendments. Table 2 is a comparison of TSCA and the 6th Amendment of the EEC classifications. 

Technical Enzymes. When an enzyme is used for a technical appHcation, ie, industrial but nonfood and nonfeed, its regulatory status is determined by its properties as a naturally occurring substance. These properties determine the classification and consequent labeling in accordance with existing schemes for chemicals. It should be noted that enzymes are not Hsted as dangerous chemicals. 

Substances or preparations requiring to be labelled with the risk phrase R45 (may cause cancer) or R49 (may cause cancer by inhalation) under CHIPS are listed in Table 5.16 after the 5th edition of the Approved Supply List (Information approved for the classification and labelling of substances and preparations dangerous for supply). This list excludes certain coal and oil-based substances which attract the phrase R45 only when they contain a certain percentage of a marker substance (e.g. benzene). 

Substanees hazardous to health inelude substanees labelled as dangerous (i.e. very toxie, toxie, harmful, irritant or eoiTosive) under any other statutory requirements, agrieultural pestieides and other ehemieals used on farms, and substanees with oeeupational exposure limits. They inelude harmful miero-organisms and substantial quantities of dust. Indeed any material, mixture or eompound used at work, or arising from work aetivities, whieh ean harm people s health is apparently eovered. 

A list of danger categories is given in Table 14.2. Note that chemicals may possess several hazards, e.g. nitric acid is classed as both an oxidizer and a conosive. If a chemical is not in one of these categories it is not generally considered to be dangerous. If the hazards of a new chemical have not been established it should be labelled Caution - substance not yet fully tested . Mixtures can be classified either from results from tests on the preparation, or by calculation to predict the healtli effects of the product based on the properties of individual components and tlieu concentration in the mixture. Preparations need to be classified for both physico-chemical and health effects but, to date, not for environmental effects.
