What are the correct distress channel?

Channel 16, which is set at 156.800 MHz, is for Distress, Urgency and Safety communication. Channel 70, set at 156.525 MHz, if for routine VHF DSC (Digital Selective Calling) watch. GUARD channels are set put above and below Channel 16 to avoid any interference on Channel 16.

121.5 MHz

What do you do if you see a distress signal?

If you See a Visual Distress Signal in the Distance Notify the nearest Coast Guard station or State authority by radio. Channel 9 on CB and Channel 16 on VHF marine radio (156.8 MHz) are recognized distress channels. If you can assist the stricken vessel without endangering yourself, you should.

What call does a distress signal require?

There are three phrases that you might hear on a VHF radio, and they all relate to safety. MAYDAY – distress signal, requires the most urgent response. This signal is only to be used when a person, or boat is threatened by grave or imminent danger, and requires assistance.

Which visual distress signal is acceptable?

Acceptable Combinations of Visual Distress Signals Some acceptable combinations include: Three hand held red flares; One electric distress light, and three hand held orange smoke distress signals; One handheld red flare and two parachute flares; or.

How often should flares be replaced?

three years

What do I do with out of date flares?

You can dispose of out-of-date flares at temporary collection points located at boat ramps along the NSW coast. The collection program begins on Wednesday 4 January 2017. Most flares have a use-by date of 3 years and must be replaced before their expiry date, or penalties apply.

Can you let flares off?

Flares contain explosives, once they are past their expiry date it is essential that out of date flares or Time Expired Pyrotechnics (TEP) are disposed of carefully. It is illegal to dump flares at sea, illegal to dump them on land and illegal to let them off in anything other than an emergency.

Can you put out a flare with water?

Emergency Flare Safe Storage and Handling Procedures Flares should be stored in a cool, dry place away from excessive heat (above 167 degrees F), and away from sparks or flames. Also, do not expose flares to water for periods longer than 10 minutes.

Does magnesium burn underwater?

Water containing large amounts of alkali earth ions is called hard water, and water containing low amounts of these ions is called soft water. In what way and in what form does magnesium react with water? Magnesium fires cannot be extinguished by water. Magnesium continues to burn after oxygen is depleted.

Are Orion flares waterproof?

These flares meet the US Coast Guard requirements, and are waterproof with a built-in protective handle.

How do you make fire underwater?

Simple, it just needs to bring its own oxygen and either burn hot enough to overcome water’s cooling or be somehow insulated from the water. Thermite, once burning, will happily burn under water.

Can there be fire in space?

Fires can’t start in space itself because there is no oxygen – or indeed anything else – in a vacuum. Yet inside the confines of spacecraft, and freed from gravity, flames behave in strange and beautiful ways. They burn at cooler temperatures, in unfamiliar shapes and are powered by unusual chemistry.

Does napalm burn underwater?

Napalm is basically thick oil or jelly mixed with fuel (petrol, gasoline). Versions of Napalm B containing white phosphorus will even burn underwater (if there is trapped oxygen in folds of cloth etc.) so jumping into rivers and lakes won’t help those unfortunate souls attacked with this vile weapon.

Can you burn underwater?

Up to 40% of total UV radiation hits the body even half a metre below the surface of the water, according to SunSmart. Ordinarily, you would have to dive at least 2.5m inshore and 4.5m in offshore coastal waters to avoid harmful UV radiation.

Do UV rays penetrate pool water?

Sun exposure can’t be ignored while swimming, either. Up to 40 percent of UV rays can penetrate shallow water. Don’t forget reflected light. Hiking or skiing in the mountains can also mean more sun exposure because UV radiation increases with altitude.
