TM 1-1500-204-23-6PRECAUTIONARY DATAPersonnel performing instructions involving operations, procedures, and practices which areincluded or implied in this technical manual shall observe the following instructions. Disregardof these warnings and precautionary information can cause serious injury, death, or an abortedmission.WARNINGS, CAUTIONS, and NOTES are means of attracting attention to essential or criticalinformation in a manual. Definitions are outlined as follows.WARNING: An operating or maintenance procedure, practice, condition, statement, etc , whichif not strictly observed, could result in injury to or death of personnel.CAUTION: An operating or maintenance procedure, practice, condition, statement, etc., which,if not strictly observed, could result in damage to, or destruction of, equipment or loss ofmission effectiveness or long term health hazards to personnel.NOTE: An essential operating or maintenance procedure, condition, or statement, which mustbe highlightedWARNINGELECTRICAL TESTSElectrical power up to 500 volts is used in testing the equipment. Exercise extreme caution during these tests.ELECTRICAL EQUIPMENTAll switches and electrical equipment shall be of the enclosed explosion-proof type All metal apparatus shall be groundedto avoid the danger of igniting test fluid fumes or creating electrical shock.USING SOLVENTS/PAINTSStandard precautions such as fire prevention and adequate ventilation shall be exercised when using solvents orapplying primer and coating.Wear gloves or gauntlets when handling solvents as solvents may cause skin disorders.Cements and solvents used to repair liferafts are flammable and shall be treated as such. Never smoke or permit anytype of open flame near when using cements or solvents.Dichloromethane (methylene chloride) vapor is heavier than air; adequate ventilation shall be provided for workingpersonnel. Dlchloromethane (methylene chloride) is toxic when vapors are inhaled over an extended period of time.Acrylic monomer and polymer base adhesive, MIL-A-8576, Type II, contains a volatile liquid which may prove toxic whenvapors are inhaled over extended periods. Use only with adequate ventilation.Observe fire precautions when using aliphatlc naphtha, Federal Specification TT-N-95.a
TM 1-1500-204-23-6HANDLING PLASTICSWear gloves to protect hands while handling hot plastic Boiling water shall not be used for heating acrylate base plastics.Provide adequate ventilation when working with Furane Plastics, Epocast H-991-A, Furane hardener 941, or equivalentsas these materials are toxic.LUBRICATING OILLubricating oil, 1 MIL-L-7808 or MIL-L-23699, contains an additive which is poisonous and absorbed readily through theskin. Do not allow oil to remain on skin any longer than necessary.FUELWhen servicing aircraft or support equipment, clean up spilled fuel with cotton mops or cotton rags. Wash off any fuel onhands, body or clothing.HANDLING ACIDWear protective clothing when mixing acid with water. Always pour acid into water, never water into acid.MAGNESIUM ALLOY FIREDo not use water or any standard liquid or foam-type fire extinguishers on a magnesium alloy fire, as they may cause anexplosion. Use dry sand or talcum powder, Federal Specification U-T-30.REMOVING CORROSIONTake precautions to prevent possible dust explosions when removing corrosion from steel alloys. Use goggles or faceshield when removing paint or corrosion with a wire brush or by the grinding method.TIRES AND WHEELSIf it is necessary to approach a wheel with a hot brake, do so either from directly in front or directly behind the aircraft.Use extreme caution when prying out foreign material imbedded in tire tread.Do not use air bottles or booster pumps not designed for tire inflationOXYGEN SYSTEMDo not allow petroleum base products to come in contact with oxygen system components, as an explosion or fire mayresult.Do not use masking tape to seal openings in oxygen regulators. Masking tape constitutes a safety hazard when used oneither serviceable or repairable oxygen equipment.Do not use drycleaning solvent, Federal Specification P-D-680, near oxygen storage or transfer systems; the combinationof these two will form a highly explosive mixture.b
TM 1-1500-204-23-6FIRE EXTINGUISHERSHalon type fire extinguishers, Monobromotrifluoromethane (CF3BR) and Bromochloromethane (CB) are odorless gasses.When used in confined areas, available oxygen for breathing may be depleted. Use supplied breathing air when usingthese gasses in enclosed spacesHYDRAULIC FLUIDTo avoid contamination, do not use previously opened cans of hydraulic fluid. Cans of hydraulic fluid can not beresealed. Immediately transfer unused hydraulic fluid to an approved airtight, pressure venting, stainless steel storagereservoir, an approved hydraulic servicing unit or a hydraulic test stand containing the same type hydraulic fluid.When opening can, clean top and use a clean, sharp, unplated intrument to prevent contamination. Can openersattached to the aircraft must be cleaned before using.NOISE HAZARDNoise levels reached during ground runup of Army aircraft are of a level that may cause permanent hearing loss.Maintenance personnel shall wear adequate hearing protection when working on aircraft with engines in operationCOMPRESSED AIRCompressed air shall not be used for cleaning purposes except if reduced to less than 30 psi and then only with effectivechip-guarding and personal protective equipment.ENGINE OIL - TURBINETo avoid contamination, do not use previously opened cans of engine oil. A new sealed can of fluid must be opened andused. When opening can, clean top and use a clean sharp, unplated instrument to prevent contamination.MERCURYA very small amount of mercury may produce hazardous vapors. Refer to TM 385-4, Safety Precautions forMaintenance of Electrical/Electronic Equipment, for safety precautions to use when handling mercury and for methodsthat are used to clean up mercury spillage.PROPER USE OF PLATED TOOLSUse only chrome plated steel or unplated steel tools for disassembly or reassembly procedures described in this manual.Use of cadmium or zinc plated tools is not permitted since these platings are prone to chipping and flaking. Should thesechips or flakes become embedded in aircraft parts galvanic corrosion will result. Should these chips or flakes enter fuelor oil wetted components they may eventually clog the filter or produce intergranular attack of nickel or titanium basealloys at elevated temperature. All tools regardless of type plating should be serviceable and free of chipping.Change 3c/(d blank)
