62. This signal is designed primarily for distress signaling, and is similar in purpose to the Grenade, Smoke, White (HC), AN-M8, which it will replace in life-raft kits. The Distress Smoke Hand Signal Mk 1 Mod 0 contains a pyrotechnic mixture which, when ignited, pro-duces a volume of orange smoke for a period of 18 seconds, pplus or minus three se-conds. The signal itself is encased in metal cylindrical body, 3 7/8 inches in lenght and 1 5/8 inches in diameter. Its weight is 0.37 pounds. One end of the cylinder is closed by a soldered cap and pull ring, which is of proper size to allow insertion of the index finger when the singal is to be fired. The signal is so constructed that it can be held comfor-tably and safely in the bare hand during the burning period. Being watertight, it is not adversely affected by moisture. See Fig. 30.

Operation

63. Distress Smoke Hand Signal Mk 1 Mod 0 is ignited as follows:

(a) Tear off sealing tape from around end of cylinder and remove the paper cap.

(b) Bring pull ring down over the rim of the can and press down, using the ring as a lever to break the seal.

(c) Point cylinder away from face and give a quick pull on the pull ring, which will come away from the can, thereby igniting the smoke mixture. Immediate emission of smoke will result. The signal should be held at arm's length at an angle of about 30 degrees from the horizontal, to prevent possibility of hot drippings or discharge falling on the hand.

Packing and Stowage

64. The Distress Smoke Hand Signal Mk 1 Mod 0 should be stowed in a cool, dry place, and in nos case at a temperature higher than 100 degrees Fahrenheit. It may be stowed with other pyrotechnic ammunition. It is packed 100 per wood shipping case. Gross weight packed is 50 pounds. Corrugated dividers serve as a means of segregation within the case.

(a) This signal is now available in limited quantity for issue from naval ammunition depots, and it is believed that ample stocks for essential uses will be available prior to 1 February 1945. This item will not be placed on pyrotechnic allowance lists until adequate supplies are available, and until reports from the field indicate quantities desired. All available stocks are being made available immdediately to the Commanders in Chief, Atlantic and Pacific Fleets.
