General Safety Handling Consideration

Chemical reagents are classified according to their hazardous nature, such as being flammable, harmful, toxic, irritant, corrosive, hazardous when decomposed during storage or dangerous for the environment. Some reagents bear a combination of such hazards.

Our labels and Materials Safety Data Sheets (MSDSs) are created using the latest available information. In some cases, however, comprehensive data are not available or hazards are yet to be found. Even if there is no definite description of hazard on a reagent’s label, MSDS, or in references, one should not assume that it is safe to handle. This is particularly true in the case of a new reagent which has only been made on a very small scale and therefore whose properties have not been fully investigated.

Hazardous reagents must be handled carefully, taking appropriate measures at all times. To prevent possible accidents, it is important to treat all reagents as potentially hazardous and to follow precautionary procedures:

• - Always read the description on the product label on receipt and check that it is as expected.
• - Use preventive measures to avoid dropping containers or spilling chemicals.
• - Read the description on the label before use, and put any required safety measures into practice. If the description mentions no danger or toxicity, you should still handle the product carefully.
• - Be sure to wear suitable protective equipment and handle with caution.
• - Refer to the MSDS, related regulations, literature, etc., and use safety measures appropriate to the characteristics of the reagent.
• - Ideally, reagents should be used promptly after purchase. The management, storage, and subsequent use of residual quantities must be carefully undertaken as the decomposition of sensitive reagents may produce additional hazards.
• - Our reagents should be handled by qualified personnel. Inexperienced users should be adequately supervised by a specialist.
• - Waste materials and any surplus or old reagents must be treated according to the relevant regulations.

The reagents supplied by TCI, except those with specific descriptions and known bulk pharmaceuticals, are intended to be used for research and development. They are not to be used to produce pharmaceuticals, quasi-drugs, cosmetics, agricultural chemicals, insecticides or food additives. Under no circumstances are they intended for use at home. When improper use is suspected, TCI reserves the right to refuse to supply any product, as is also dictated by law, and takes no responsibility for any improper use.

Our reagents may contain items regulated by local laws. Please contact your local TCI office or distributor, or your local regulatory office, for more details.

When controlled substances are sold or purchased for testing and experimental purposes, details of the buyer’s appropriate licence or qualification, or a predetermined procedure based on the related regulations, may be required.

TCI does not guarantee that a new chemical substance manufactured by using our reagents, or that using our reagents in combination with other products, or using them in certain procedures does not infringe on any patents of Japan or any other countries. It is the buyer’s responsibility to ensure that no patent is infringed.
