Since chloroacetyl chloride can react with water in the skin or eyes to form chloroacetic acid, its toxicity parallels that of the parent acid. Chloroacetyl chloride can be absorbed through the skin in lethal amounts. The oral LD q for rats is between 120 and 250 mg/kg. Inhalation of 4 ppm causes respiratory distress. ATLV of 0.05 ppm is recommended (28,41). 

Avitrol [504-24-5] (4-anHnopyridine) (24), mp 155—158°C, bp 273°C, has repeUent—toxicant properties for birds and is classed as a severe poison and irritant. This secondary bird repeUent can be used as a broadcast bait, causing uncoordinated flight and distress caUs and escape responses in nearby birds (57). A reevaluation shows lack of effectiveness of 1% baits but better control of blackbirds with 3% baits (58). Suspected contamination of drinking water with 4-aminopyridine has been reported in toxicosis of Brahman catde and horses (59). 

Distressing Stains. Interest and charm can be added to furniture by the dehberate infliction of imperfections. These imperfections may be caused by physical distress such as hammers, files, nails, chains, or rocks or caused by finish distress such as "dy specking" or staining to simulate past abuse, such as waterstains caused by the careless placement of a drinking glass. 

Physical distressing is usually a part of the initial finishing procedure and is done in the white wood stage. Finish distressing is normally part of the latter phases of the finishing operation. Like the pad and shade stains, distressing stains are usually appHed over the sealer or between coats of topcoat. 

The principal use of strontium nitrate is in the manufacture of pyrotechnics (qv) as it imparts a characteristic, hrilliant crimson color to a flame. Railroad fusees and distress or rescue signaling devices are the main uses for strontium nitrate. It is also used to make red tracer bullets for the military. 

Pantothenic acid toxicity has not been reported in humans. Massive doses (10 g/d) in humans have produced mild intestinal distress and diarrhea. Acute toxicity was observed in case of mice and rats by using calcium pantothenate at fairly large doses (92). 

Inhalation of vapors of lower chloroformates result in coughing, choking, and respiratory distress, and, with some chloroformates like methyl chloroformate, inhalation can be fatal as a result of the onset of pulmonary edema, which may not appear for several hours after exposure (55). Table 5 gives the acute toxicides of some chloroformates (55—57). 

It is also common to distress the surface for resemblance to antique furniture. For example, spots of black pigment stain can simulate India ink spots dropped from quiH pens, and dark stains carefully appHed into corners simulate dirt accumulated over many years. When this "art work" is completed, a sanding sealer is appHed to immobilize the lower layers of the finish and to provide a surface that can be sanded smooth. Finally a top coat is appHed and poHshed smooth. 

Since the higher thermal conduc tivity material (copper or bronze) is a much better bearing material than the conventional steel backing, it is possible to reduce the babbitt thickness to. 010-030 inch. Embedded thermocouples and RTDs will signal distress in the bearing if properly positioned. Temperature-monitoring systems have been found to be more accurate than axial-position indicators, which tend to have linearity problems at high temperatures. 

Example 1 the English pronunciation of benzene sounds like benzyne in Dutch, consequently a verbal instruction to add benzene to a process in distress could have dire consequences. 

Dye penetrant inspection of the hardware to determine the extent of distress in order to develop material requirements and repair techniques. 

Rpm X number of gear teeth (always present) Gear mesh frequency Record signal for reference Distress noisy and shows increase m GML and harmonics One-half GML—even number of teeth with machining error... 

A method of assuring nearly perfeet tooth eontaet is to mateh-lap the gear teeth after nitriding. Lapping eliminates the break-in period, whieh otherwise takes from 70 to 120 hours. It is during the break-in period, that tooth surfaee distress usually oeeurs. 

A crystal material is excited by the force imposed on it by an internal I v mounted mass. A voltage is produced by the crystal proportional to accel eration. This voltage is then amplified by a charge amplifier type signal conditioner from whence the signal can be transmitted long distance. (1.000 feet is not uncommon) to the monitor/readout unit. It is calibrated in terms of gravitational units (g), which are proportional to force. Force is ttnc of the most reliable indicators of equipment distress.
