Drysuit becomes flooded

In the unlikely event of this occurring (probably caused by a tear, seal failure or zip 

failure etc.), use your buoyancy device to return to the surface.

It may help to keep the leaking area as low in the water as possible - this will help 

keep any remaining air inside the drysuit. Cold water in the drysuit means that it 

should be removed as soon as possible after surfacing.

Be aware that it is normal for the inside of a drysuit to be damp with perspiration, 

and a small amount of water should not be assumed to be because of a leak or 

drysuit failure.

Dropped or lost weight belt

To practise this procedure, do so with consultation and supervision from a suitably 

qualified instructor in a controlled environment – they will guide you through what 

to do.

Do not attempt to drop your weight belt until you are absolutely clear about the 

procedure. You must be thoroughly trained.

Remember, dropping your weight belt can injure other divers and marine life.

Other Important Information

1. Follow all instructions. Improper use of a drysuit can cause loss of buoyancy 

control, including uncontrolled descents and ascents, and a risk of serious injury or 

death.

2. Improper use or misuse of a drysuit can result in exposure to thermal hazards 

and rapid body overheating or cooling, which could result in stroke, seizure, 

hypothermia and death.

3. This manual is 

NOT

 a substitute for proper qualified drysuit instruction and 

is 

NOT

 supplied as such. This manual is supplied as a guideline for drysuit 

maintenance only.

4. Diving in conditions that contain chemical, biological or nuclear contaminants is 

extremely hazardous and should 

NOT 

be attempted without being specially trained 

and equipped. In most cases, the Northern Diver drysuit you have purchased has 

NOT

 been adapted for use in polluted or abnormal conditions and is therefore 

NOT

 

covered under warranty. Some drysuits that we manufacture are suitable for these 

conditions, but prior to use you 

MUST

 seek advice from us to ensure the drysuit 

will fully protect you.

5. Military drysuits – if the drysuit is to be used in conditions where the drysuit 

requires a non-magnetic signature, please carry out adequate checks to confirm 

that the zips and valves fitted to the drysuit comply with the directive relating to 

this use. Non-magnetic inflation and exhaust valves can be identified with this 

symbol - 

To use the non-magnetic symbol for our diving suits and equipment 

we have our products independently tested at QinetiQ, Portland. 

We advise you to ensure your kit has been tested before entering 

any hazardous area.
