Solvents safety regulations

Color Properties Required. Colorants must be chosen to permit formulation of a coating that can meet performance requirements such as exterior durability and resistance to solvents, chemicals, and heat. Health and safety regulations may also affect colorant choice. [Pg.345]

PRESSURE SYSTEM Defined in the Pressure System Safety Regulations 2000 as a system containing one or more pressure vessels of rigid construction, any associated pipework and protective devices the pipework with its protective devices to which a transportable gas container is, or is intended to be, connected or a pipeline and its protective devices which contains or is liable to contain a relevant fluid, but does not include a transportable gas container. Here relevant fluid is steam any fluid or mixture of fluids which is at a pressure of >0.5 bar above atmospheric pressure, and which fluid or a mixture of fluids is a gas, or a liquid which would have a vapour pressure of >0.5 bar above atmospheric pressure when in equilibrium with its vapour at either tlie actual temperature of the liquid or 17.5°C or a gas dissolved under pressure in a solvent contained in a porous substance at ambient temperamre and which could be released from the solvent with the application of heat. [Pg.17]

Solvents. Solvents affect adhesive viscosity, bond strength development, open time, cost, and ultimate strength. Blends of three solvents (aromatic, aliphatic, oxygenates, e.g. ketones, esters) are generally added, and in their selection environmental and safety regulations must be considered. A graphical method has been proposed to predict the most adequate solvent blends for solvent-borne CR... [Pg.664]

The correct disposal of chemicals, reagents and solvents is a matter of good laboratoiy practice and should comply with national and/or environmental and/or health safety regulations. [Pg.105]

All students undertaking syntheses as part of their laboratory studies should be fully conversant with the safety data for each chemical used, each compound prepared and the correct method of disposal for all solvents, solutions and residues. The information in Appendix 2 is intended to be a guide in this respect local safety regulations must always take precedence. Students should also follow standard operating procedures for any techniques described and discuss all the details of the experiments with a suitably qualified and experienced supervisor before starting an unfamiliar procedure. [Pg.186]

In addition to selecting an efficient solvent, manufacturers must now contend with environmental and safety regulations imposed by federal, state, and county jurisdictions. Solvents must meet volatile organic compounds (VOC) limits and, of course, there are also toxicity and flammability hazards that have to be addressed. [Pg.158]

One major automobile manufacturer was concerned about the use of urethane coatings with regard to solvent safety and emissions regulations. The cost and size of the complex coating supply and solvent evaporation equipment were other issues. Also, a 2 hr oven time limited the type of board it could coat and presented a severe handicap to short-run production and just-in-time delivery systems. [Pg.782]

The basic principles are the same for the preparation of both the cellulose acetate dope and the cellulose triacetate dope with the exception of the particular solvent mixture used for each. The flake, the solvent mixture, and a filtering aid are added to a heavy-duty mixer. The solution is prepared in a fully enclosed system to minimize solvent losses and also to meet strict exposure levels regarding the workers. In the case of cellulose acetate, the main solvent is acetone, which is highly flammable. Therefore, the vapor-air ratio must be maintained at a level that meets safety regulations. Strict fire codes are maintained in the dope-preparation department as well as in the fiber-spinning department. [Pg.786]

While white spirit has a flash point of about 40 C the loss of the heaviest components such as undecane (59 C) and decane (45 C) is certain to mean that the recovered solvent will have a lower one, possibly less than 32 C at which safety regulations may be applicable. [Pg.371]

The concentration of these solvents is controlled by international safety regulations, which allow limits in the range of a few ppm. [Pg.295]

A brief summary of the environmental and safety regulations are given in this chapter in an effort to inform the reader about these regulations, and the responsibility to know the regulations and to follow correctly their recommendations. The concerns for environmentally acceptable practices are in part the result of the establishment of the United States Environmental Protection Agency (EPA) in 1970. The Environmental Protection Agency administers several laws of particular concern to solvent producers and solvent users. These laws include the Clean Air Act (CAA) the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund) the Resource Conservation and Recovery Act (RCRA) the Toxic Substances... [Pg.4]

Open fluid bed units are not capable of mamtainmg environmental protection demands when materials to be dried are moistened by organic solvents. Fluidized bed units are therefore equipped with closed duct systems as well as solvent recovery systems (Scheme 13.2). Due to safety regulations (solvent vapour and dust explosion) the entire apparatus needs to be filled with inert gas prior to process... [Pg.251]

The choice of extraction solvent in the preparation of the ingredients for foodstuffs is thus limited by the safety regulations described above. [Pg.37]

The safety of workers is the task of OSHA, which was established to set minimum standards such as solvent vapor exposures to protect workers health and safety. In large companies there will be persons who will have the responsibility of knowing all the details of the environmental and safety regulations. An overview of the environmental and safety regulations is given in this chapter in an effort to inform the reader. It is the reader s responsibility to know the regulations and to correctly follow their recommendations. [Pg.124]

Chemical and solvent contact can also inhibit the performance of both adhesives and sealants. While a mild solution of detergent may not affect performance, using the same undiluted may cause failure within hours of contact. Testing for the effects of chemical and solvent contact is relatively straightforward, but should only be carried out under local health and safety regulations most manufacturers will hold this information. [Pg.155]

There is now much pressure from environmental and health and safety regulators to reduce or eliminate the use of solvents in adhesives, and the industry is responding by developing water-based systems to replace them. However, a fundamental problem is the low rate at which water evaporates because of its high heat of evaporation, which is about five times greater than for common solvents. [Pg.417]
