Manufacturing importance

Precise coatrol of the course, speed, and extent of the reaction is essential for successful manufacture. Important factors are mole ratio of reactants catalyst (pH of reaction mixture) and reaction time and temperature. Amino resias are usually made by a batch process. The formaldehyde and other reactants are charged to a kettie, the pH adjusted, and the charge heated. Often the pH of the formaldehyde is adjusted before a dding the other reactants. Aqueous formaldehyde is most convenient to handle and lowest ia cost. 

Represents manufacturers, importers and distributors of chemicals, petrochemicals, resins, adhesives, sealants and plastic products in Australia and New Zealand. 

While MSDS s arc not required to be physically attached to a shipment, they must accompany or precede Oic shipment. When tlie manufacturer/supplicr fails to send an MSDS with a sliipmcnt labeled as a liazardous chemical, the employer must obtain one from Oie chemical manufacturer, importer, or distributor as soon as possible. Similarly, if the MSDS is incomplete or unclear, the employer should contact the manufacturer or importer to get clarification or obtain missing information. 

Section 6 of the Act has been amended by the Consumer Protection Act 1987 and now imposes specific duties on manufacturers, importers, designers and suppliers to ensure that articles and substance supplied for use at work are safe and without risk to health.

Counterfeit products, products of dubious quality and faulty information — especially exaggerated claims of efficacy — are often found to be widespread in the informal sector. Unlicensed manufacturers, importers, wholesalers, retailers and even persons engaged in the pharmaceutical business pose difficult challenges to dmg regulation. The DRA should not allow the informal sector to remain a loophole in regulation. Monitoring of pharmaceutical activities should cover the informal as well as the formal sector. 

Spedficalions regarding pharmaceutical premises, personnel and procedures must be followed by pharmaceutical manufacturers, distributors and retailers if they wish to obtain and retain their licence to operate. By means of these licences, dmg regulatory authorities control the activities of pharmaceutical manufacturers, importers and distributors and companies engaged in dmg promotion and advertising. 

The first three objectives relate to pharmaceutical products, and the fourth to pharmaceutical usage although, in most countries, promoting rational use of dmgs is not part of regulatory activities. In order to achieve the four objectives, the various pharmaceutical activities— manufacturing, importation, exportation, distribution... 

In almost all countries, dmg laws require that establishments engaged in the manufacturing, importation, distribution or sale of pharmaceuticals should be licensed and regularly inspected. 

If the purpose of dmg regulation is to promote public health and protect the public from harmful and dubious dmgs, it should cover all products for which medicinal claims are made and all activities associated with the manufacture, importation, distribution, dispensing and promotion of dmgs. 

Users of electrical and electronic appliances must bring worn-out appliances back to the manufacturers, importers, or dealers or to specialized disposal firms. 

Manufacturers, importers, and dealers of electrical and electronic appliances are obliged to take back worn-out appliances. 

Many laboratory syntheses of important structural types of compounds are too long or complex to work well in manufacturing. Chemists working in the process area are thus often engaged in inventing new approaches that use the most modern reactions, in order to develop compact synthetic schemes with small numbers of acceptable steps. The modern reactions that make this possible are being invented by chemists involved in basic discovery and creation, usually in universities. The pressure on industrial process chemists to develop practical schemes for manufacturing important products means that they do not normally have the time for the basic research that can lead to new chemical reactions. 

According to the Emergency Planning and Community Right-to-Know Act (EPCRA) of 1986, 42 U.S.C. Section 11023, industries are required to submit chemical release and off-site transfer information to the EPA. Section 313 of Title III of EPCRA requires owners and operators of certain facilities that manufacture, import, process, or otherwise use the chemicals on this list to report annually their release... 

The core of the new EU scheme to control chemicals is REACH Registration, Evaluation and Authorisation of Chemicals (32, 93). REACH will place a duty on companies that manufacture, import and use chemicals in the EU to assess the risks arising from their use, which will often require safety testing, and manage any risks identified.

If the manufacturer, importer or user of a chemical of very high concern can demonstrate that no viable alternative is available, that there is need forthe chemical (with a transparent socio/economic assessment) and that all steps are taken to minimise exposure, and therefore risks, from continued use of the substance, then a time-limited authorisation may be granted. Atime-limited authorisation will both ease costs of a phaseout and encourage development of alternatives.

According to the German word Akteure, actors in an innovation system means manufactures, importers and users of chemicals (actors in the supply chain, economic actors) as well as authorities, science, public interest groups and other participants outside the supply chain (cf Figure 1). 

The scope of data sets to be submitted for registration depends on the marketing volume of the substance. If new substances are to be marketed in a quantity > 1 t/a., test results have to be presented in accordance with a legal catalogue of basic data . In the case of larger quantities additional tests must be presented, in the case of smaller quantities more simplified data sets are sufficient . On the basis of the substance data sets those uses must be evaluated, which are intended by or known to the manufacturer/importer.
