ROCKET PARACHUTE FLARE is a distress signal that can be suspended from the parachute for a certain period of time after being launched to a certain height in the air, and emits red light with a certain luminous intensity and falls at a slow speed. The marine rocket parachute flare should be installed in a waterproof enclosure. The enclosure should be printed with concise instructions or diagrams that clearly state the use of the rocket parachute flame signal. At the same time, there is a complete set of ignition devices.
The visual signal is the signal that is sent when the ship needs to be rescued. In order to make the ship and the aircraft to the rescue find the ship difficult. Visual signals include rocket parachute flame signals, hand-held flame signals, and floating smoke signals.
The rocket parachute flame signal is emitted by the rocket to an altitude of no less than 300 m. At its apex or near the apex, the rocket will emit a bright red flame with a parachute. The flame can be burned evenly for not less than 40 s, emits light with a light intensity of not less than 30 000 cd, and has a falling speed of no more than 5 m/s. It does not burn the parachute or accessories when burned. This signal is easier to find by rescue boats.
International Maritime Organization (IMO) requirements:
I. the rocket parachute flame signal should meet the following requirements:
1) mounted in a waterproof enclosure;
2) on the enclosure with a brief description or illustration that clearly states the use of the rocket parachute flame signal;
3) with an integrated ignition unit;
4) when used in accordance with the manufacturer's operating instructions, personnel holding The outer casing does not feel uncomfortable.
II. When launching vertically, the rocket should reach a height of not less than 300m. At the apex of its ballistics, or near the apex of its ballistics, the rocket emits a parachute flame, which should have the following characteristics:
1) emit bright red light;
2) the combustion is uniform, the average light intensity is not less than 30,000 cd;
3) has a burning time of not less than 40 s;
4) has a parachute speed of not more than 5 m/s; and
5) does not burn the parachute or the attachment when burning.
TYPES AND USE
There are many types of rocket parachute flare. The main difference is that the launcher is different. More common are the two types of hair and pull. When using, pay attention to the instructions for use and operate according to their requirements.
1. Method of using the rocket-type rocket parachute flame signal
(1) Remove the plastic bag, remove the top cover and the bottom cover, and pay attention to keep the arrow on the outer casing facing upwards;
(2) Put down the hinged lever of the bottom trigger, hold the rocket launcher in one hand, raise the head vertically, and hold the palm of the other hand on the pressure bar;
(3) Push the pressure bar up, and quickly hold the rocket with both hands. When the wind is strong, the wind will be slightly upward, and the rocket will be launched soon.
2. The use of pull-type rocket parachute flame signal:
(1) Remove the top cover and bottom cover, and take care to keep the arrow on the cover facing up.
(2) Pull out the lower end of the parachute rocket signal.
(3) Grasp the cable and pull it down.
(4) Launch the rocket parachute flare.
Special attention should be paid when transmitting rocket signals: Some rocket signals tend to be delayed for a period of time when launching. Try to hold the rocket simplified body with both hands. However, if the rocket has not been launched after 10 s of firing, the rocket signal should be thrown into the water as soon as possible to prevent danger.
