Monoethan olamine and monoisopropan olamine may be moderately toxic by absorption through the skin. The other amines are low in toxicity by this route and are not likely to be absorbed in acutely toxic amounts. In the event of skin contact, clothing and shoes should be removed promptly, and the skin thoroughly washed with water. Contaminated clothing should be thoroughly cleaned before reuse shoes and leather products should be discarded. 

In case of physical contact with sulfuric acid, immediately flush eyes or skin with plenty of water for at least 15 min while removing contaminated clothing and shoes. Call a physician. Wash clothing before reuse and destroy contaminated shoes. 

Ethylene dibromide is a suspected human carcinogen and worker exposure by all routes should be carefiiUy controUed to levels as low as reasonably achievable (67). Ethylene dibromide causes severe blistering of the skin if contact is prolonged. Eye contact with the Hquid will cause pain, irritation, and temporary impairment of vision. Recommended safety equipment includes safety goggles, a NIOSH approved canister-type gas mask for organic vapors, neoprene gloves, and neoprene overshoes. In case of contact with ethylene dibromide, contaminated clothing and shoes should be removed and eyes or skin washed with plenty of water for at least 15 minutes. Contaminated clothes should be washed before reuse and contaminated shoes should be discarded. 

The crystallization of wax from lubricating oil fractions makes better oil. This is done by adding a solvent (often a mixture of benzene and methyl ethyl ketone) to the oil at a temperature of about -5 F. The benzene keeps the oil in solution and maintains fluidity at low temperature the methyl ethyl ketone acts to precipitate the wax. Rotary filters deposit the wax crystals on a sp woven cloth stretched over a perforated cylindrical drum. A vacuum in the drum draws the oil through the perforations. The wax crystals are removed from the cloth by metal scrapers and ol vent-washed to remove oil followed by solvent distillation to remove oil for reuse. 

Cleanse tools, equipment, and clothing that have been exposed to hazardous materials before storing or reusing them. 

William Henry Perkin, an 18-year-old working in the back room and outdoor shed of his London home, had discovered in black coal tar a beautiful purple dye that would change the world. For the first time in history, color could be democratized. William Henry Perkin and his purple, later known as mauve, rescued the poor and middle classes from their age-old austerity of hues. Natural dyes were expensive and, before Perkin s synthetic mauve, millions of poor people lived their lives in untreated drab and dingy fibers. Even for the middle class, pieces of brilliantly dyed cloth were treasures to be reused from garment to garment and from year to year. It was the schoolboy William Henry Perkin and his successors who would give the world the ample abundance of tints that only the rich had previously enjoyed. 

Skin Contact Wash skin at once to remove cyanide while removing all contaminated clothing including shoes do not delay Skin absorption can take place from cyanide dust, solutions, or hydrogen cyanide vapor. Absorption is slower than with inhalation, often measured in minutes rather than seconds (AC or HCN is absorbed much faster than metal cyanides from solutions such as sodium, potassium or copper cyanide solutions). After going though decontamination on the victim(s), watch him or her for at least one to two hours, if possible, since absorbed cyanide can continue to work into the blood stream. As a final note, wash clothing before reuse, and destroy contaminated shoes. 

PVA/acrylamide blend membranes prepared on cheese cloth support by y-irradiation induced free radical polymerization can be used for urease entrapment. The enzyme urease is entrapped in the membrane during polymerization process and using glutaraldehyde as cross-linking agent. The main advantage of this blend to this process is that it can be reused a number of times without significant loss of urease activity [292],...
