WARNING

Personnel performing operations, procedures, and practices which are included or implied in this technical manual shall

observe the following warnings. Disregard of these warnings and precautionary information can cause serious injury or loss

of life.

BATTERY ELECTROLYTE

Battery electrolyte is harmful to the skin and clothing. If potassium hydroxide is spilled on clothing or other material, wash

immediately with clean water. If spilled on personnel, immediately ?ush the affected area with clean water. Continue

washing until medical assistance arrives. Neutralize any spilled electrolyte by thoroughly ?ushing contacted area with water.

CARBON MONOXIDE

When smoke, suspected carbon monoxide fumes, or symptoms of anoxia exist, the crew should immediately ventilate the

cockpit.

ELECTROMAGNETIC INTERFERENCE (EMI)

No electrical/electronic devices of any sort, other than those described in this manual or appropriate airworthiness release

and approved by USAAMCOM AMSRD-AMR-AE-U, are to be operated by crewmembers or passengers during operation

of this helicopter.

FIRE EXTINGUISHER

Exposure to high concentrations of extinguishing agent or decomposition products should be avoided. The liquid should not

be allowed to come into contact with the skin, as it may cause frost bite or low temperature burns.

HANDLING FUEL AND OIL

Turbine fuels and lubricating oils contain additives which are poisonous and readily absorbed through the skin. Do not allow them to remain on skin longer than necessary.

HIGH VOLTAGE

All ground handling personnel shall be informed of high voltage hazards when making external cargo hookups.

NOISE

Sound pressure levels in this helicopter during some operating conditions exceed the Surgeon General¡¯s hearing conservation criteria, as de?ned in DA PAM 40-501. Hearing protection devices, such as the aviator helmet or ear plugs are required

to be worn by all personnel in and around the helicopter during its operation. When window guns are ?ring, when ?ights

exceed 100 minutes during any 24 hour period, or when speeds are above 120 knots, helmet and ear plugs shall be worn by

all crewmembers.

WEAPONS AND AMMUNITION

Observe all standard safety precautions governing the handling of weapons and live ammunition. When not in use, point all

weapons in a direction offering the least exposure to personnel and property in case of accidental ?ring. Do not walk in

front of weapons. SAFE the machinegun before servicing. To avoid potentially dangerous situations, follow all procedural

warnings in text.

ELECTROMAGNETIC RADIATION

Do not stand within six feet of Aircraft Survivability Equipment (ASE), ALQ-156, ALQ-162, and ALQ-144 transmit

antennas when the ASE equipment is on. High frequency electromagnetic radiation can cause internal burns without causing

any sensation of heat. The HF radio transmits high power electromagnetic radiation. Serious injury or death can occur if

you touch the HF antenna while it is transmitting. Do not grasp, or lean against the antenna when power is applied to the

helicopter.

ALQ-144

Do not continuously look at the ALQ-144 infrared countermeasure transmitter during operation, or for a period of over 1

minute from a distance of less than 3 feet. Skin exposure to countermeasure radiation for longer than 10 seconds at a

distance less than 4 inches shall be avoided.

IR COUNTERMEASURES MUNITIONS

Advanced IR countermeasures munitions (AIRCMM) M-211 and M-212 ?ares should not be loaded in the M-130 general

purpose dispenser as countermeasures against IR missile threat environment. Advanced IR countermeasures munitions

(AIRCMM) M-211 and M-212 ?ares will provide inadequate IR countermeasures capability and will signi?cantly increase

aircrew vulnerability.

AIR WARRIOR

If performing a combat mission with an Air Warrior ballistic upgrade plate (BUP), the seat belt buckle must be positioned

below the BUP to prevent potential aft cyclic restriction.

When performing a combat mission or overwater mission, aviator worn gear can restrict head and torso movement. Users

should conduct ground familiarity drills (blind switch/control identi?cation) and crew coordination exercises before ?ight

since ?eld of regard can be restricted by aviator worn mission equipment. The user must strictly adhere to proper crew

coordination procedures during switch identi?cation.

Prior to ?ight, the user must perform control sweeps to ensure there are no ?ight control interference problems with aviator

worn gear. If a restriction is found, the interfering gear must be adjusted/moved to eliminate the restriction.
