Listing virtually every known product in the field, this volume supplies also names and addresses, trade names and complete catalogs of leading manu facturers.

Rubber as well as neoprene of very good quality prevents the penetration of tetraethyl lead and Ethyl Fluid for a considexable period.

I presented my credentials to Will and informed him that this was an EPA lead inspection to determine compliance with the Clean Water Act and the Consent Decree.

He is to report any out-of-spec samples immediately to the Lead Operator. 2.

vided on the card for such identification data as the serial number, rating, and location All repair work, including repair cost, should be entered on the records The date of each inspection, with a bnef comment on the condition of the motor and the effectiveness of its protective equipment, and a report of maintenance work performed should be recorded on the card Each entry should be signed by the man who makes the inspection Periodic review of motor record cards will reveal unusual conditions, such as too fre quent appearance of certain defects, inade quate maintenance of protective devices, or evidence of misapplication High-voltage equipment In general, high-voltage equipment is more carefully guarded than low-voltage equip ment because of the greater inherent hazard In newer installations of 2300 volts or more, attempts have been made to insulate or armor apparatus so that casual contact with the cur rent-carrying parts is not possible In this type of equipment, the metal clad ding, barners, or other protective coverings may require removal for inspection or repairs Before these coverings are removed, it is im perative that circuit and machines be deener gized and that circuit breakers, disconnecting switches, and controls be checked with the operator or electrician to make sure that the equipment is free from current This rule also applies to older installations with open wiring and many of the currentcarrying parts exposed and uninsulated Un der these conditions, extra care is necessary to maintain more than ample clearance when work is done near energized circuits When cables have been deenergized and dis charged, they should be shorted and grounded at the terminal switches where feedback or induction from other lines is possible Most high-voltage equipment has volt meters, ammeters, power factor meters, and essential indicators m the circuit Thermo couples or other thermometers are sometimes provided These indicators provide for safer operation since the characteristics of the ap paratus can be constantly observed and men need not make separate tests near energized circuits When high-voltage equipment not equipped with built-m indicators must be inspected, the operator or inspector should examine it carefully to see that it has a substantial ground An electrical fault in an ungrounded machine may not be visible during operation, but touching the frame may result in fatal shock A good ground will keep the machine at or near earth potential Power factor improvement capacitors are used in almost every efficiently operated dis tribution system These capacitors usually have an internal discharge resistor to reduce the voltage to 50 volts within one minute after the capacitor is deenergized Neverthe less, each terminal and the case must be grounded by means of a grounding stick whenever work is to be done on or near the capacitor This ground connection must be maintained until the entire job inspection, maintenance, or cleaning of the capacitor-- has been completed Extreme precaution should be taken when insulation resistance of high-voltage equip ment is tested to make sure that the megohmmeter is not connected into a live circuit After it has been determined that the appara tus is completely dead, the free test lead can be attached to an exposed connection by use of a switch hook or other type of insulated hot stick Rubber gloves should be worn m case of hand contact with the hanging leads Contact to test insulation resistance should be made whenever possible with an exposed conductor m the circuit to be tested Punc turing of insulation is not recommended ex cept with the knowledge and permission of the plant electrician, engineering department, or operator Then it should be understood that the place punctured will be immediately taped or reinsulated As assurance of additional safety, especially when the punctured insulation is near metal framework or grounded structures, an insula tion test should be made of the taped portion Rubber gloves should not be used as a sub stitute for safety devices or procedures, but are wom as a supplementary measure Be fore each use they should be checked for punctures, tears, or abrasions For an on-thejob test the cuffs should be rolled up and air forced into the fingers and palms ofthe gloves If there is leakage, the gloves should not be used Leather protectors should be wom over 1003

In the worst case, this would lead to a complete loss of production.
