22、 a substance via the oral route (ingestion). E1302DISCUSSIONResults of acute oral toxicity tests are used to develop warning statements on labels as may be required by OSHA Hazard Communication Standard29 CFR 1910.1200 or Federal Hazardous SubstancesAct. These are also used to establish a dosage reg

E2169, E2275DISCUSSIONBioresistant, or recalcitrant, chemicals are not readily metabolized by microorganisms.biostatic, adjable to prevent existing microbia

32、l contaminants from growing or proliferating, but unable to kill them. E2169,E2275DISCUSSIONBiostatic additives may be registered antimicrobial pesticides or unregistered chemicals with other performance properties. The difference betweenbiocidal and biostatic performance may be attributed to dose,

33、chemistry or both.boring, venlarging a hole that already has been drilled.DISCUSSIONGenerally boring is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning.breathing zone, nthat location in the atmosphere at which persons br

34、eath. D1356DISCUSSIONThe workers breathing zone consists of a hemisphere 300-mm radius in front of the face and measured from a line bisecting the ears. D7049broaching, van operation in which a cutter progressively enlarges a slot or hole or shapes a workpiece exterior.DISCUSSIONLow teeth start the

35、cut, intermediate teeth remove the majority of the material and high teeth finish the task. Broaching can be a one-step operation,as opposed to milling and slotting, which require repeated passes. Typically, however, broaching also involves multiple passes.bubbler, na sampling device consisting of a

36、 gas dispenser immersed in an absorbing liquid. D1356coining, va closed-die squeezing operation in which all surfaces of the work are restrained (coined).E2523 133DISCUSSIONCoining often imparts a pattern or shape onto the workpiece. Coining also refers to a press-brake bending operation in which th

37、e punch bottoms againstthe workpiece and the die. It also refers to a process similar to bottoming although greater force is applied. Coining alters the radius, and bottomingsets the bend open but does not affect shape.collector, na device for removing and retaining contaminants from air or other ga

38、ses. D1356contaminant, nsubstances contained in in-use metalworking fluids that are not part of the received fluid, such as abrasiveparticles, tramp oils, cleaners, dirt, metal fines and shavings, dissolved metal and hard water salts, bacteria, fungi andmicrobiological decay products, and waste. E14

In more severe cases, fissures (deep cracks) and ulcers (open sores) may develop. The condition is usually reversible whenexposure to the causative agent ceases. More
