Table 1-38.—Effects of Heat and HumidityWhen apparent temperatures are between 90 and 105 degrees, heat cramps, heat exhaustion, andheatstroke are possible after prolonged exposure and physical activity. These become likely whenapparent temperatures are between 105 and 130 degrees. Over 130 degrees, heatstroke is imminent. Youshould note that heatstroke can be fatal if medical care is delayed.GENERAL MAINTENANCEThe general maintenance section provides you with information on cleaning solvents, lubricants,corrosion control, use of the oscilloscope, troubleshooting, classes of overhaul, and types of equipmentmodifications. It also provides information such as material identification, names of organizations thatprovide outside technical assistance, and publications and documents that will assist you in day-to-daymaintenance.Corrosion Control (Cleaning and Lubricating)A corrosive atmosphere can damage unprotected electric and electronic equipment. You should beaware of the harmful effects of moisture and, in particular, salt spray and salt-impregnated air. To preventcorrosion, you should maintain an effective cleaning and lubricating schedule. Standard preventivemaintenance (PMS) procedures provide only minimum protection. Any schedule should include dustingand cleaning, lubrication of moving parts, and the use of approved solvents or wetting agents to removeany dust, dirt, oil film, salt, or other contaminant.Table 1-39 is a list of standard Navy lubricants and solvents and their uses, as specified in MilitaryStandard 454M (MIL-STD-454M).1-122
