Safety first and fire / Alarm + Extinguisher
Shit happen's , sometimes it happen's to me sometimes to you .
I have a safe pass for working on building sites , this is a day course to educate construction worker's .
The truth of the matter is you are you'r own safety officer .
So let's talk about safety , all input welcome
Like rule # 1 in growing = don't tell any one and get caught !!

RULE # 1 Get a smoke alarm , and check it regulary , change the batteries if needed . Quality brand batt's are best . Make sure it work's , check it work's .
Or use a smoke/heat detector on a circuit . This eliminates any batteries and also allows you to link all alarms in the house for quicker warning .

RULE # 2 get a powder fire extingisher , powder is safe to use on an electrical fire , they come in a range of sizes . From hendheld one litre to six litre automatic etc etc .

RULE # 3 have a plan as like i say shit happen's , how will you tackle a fire in this situation ?
The grow and all you'r euipment is irrelevent over your and others safety , fire's KILL where is your nearest safe exit ...
Class C is important to us unless you can kill the electrical supply , then you can use water . C02 work's also but can reignite .

Class A extinguishers are for ordinary combustible materials such as paper, wood, cardboard, and most plastics. The numerical rating on these types of extinguishers indicates the amount of water it holds and the amount of fire it can extinguish.

Class B fires involve flammable or combustible liquids such as petrol/gasoline, kerosene, grease and oil. The numerical rating for class B extinguishers indicates the approximate number of square feet of fire it can extinguish.

Class C fires involve electrical equipment, such as appliances, wiring, circuit breakers and outlets. Never use water to extinguish class C fires - the risk of electrical shock is far too great! Class C extinguishers do not have a numerical rating. The C classification means the extinguishing agent is non-conductive.

Class D fire extinguishers are commonly found in a chemical laboratory. They are for fires that involve combustible metals, such as magnesium, titanium, potassium and sodium. These types of extinguishers also have no numerical rating, nor are they given a multi-purpose rating - they are designed for class D fires only.

Dry chemical extinguishers come in a variety of types and are suitable for a combination of class A, B and C fires. These are filled with foam or powder and pressurized with nitrogen.
BC - This is the regular type of dry chemical extinguisher. It is filled with sodium bicarbonate or potassium bicarbonate. The BC variety leaves a mildly corrosive residue which must be cleaned immediately to prevent any damage to materials.
ABC - This is the multipurpose dry chemical extinguisher. The ABC type is filled with monoammonium phosphate, a yellow powder that leaves a sticky residue that may be damaging to electrical appliances such as a computer

Dry chemical extinguishers have an advantage over CO2 extinguishers since they leave a non-flammable substance on the extinguished material, reducing the likelihood of re-ignition.

Carbon Dioxide (CO2) extinguishers are used for class B and C fires. CO2 extinguishers contain carbon dioxide, a non-flammable gas, and are highly pressurized. The pressure is so great that it is not uncommon for bits of dry ice to shoot out the nozzle. They don't work very well on class A fires because they may not be able to displace enough oxygen to put the fire out, causing it to re-ignite.
CO2 extinguishers have an advantage over dry chemical extinguishers since they don't leave a harmful residue - a good choice for an electrical fire on a computer or other favorite electronic device such as a stereo or TV .
Automatic Dry Powder Extinguisher 6kg
^ dry powder fire extinguisher designed to be fully automatic. The unit is a stored pressure type with a mixture of dry powder and nitrogen, as the fire reaches the temperature specified on the glass bulb it shatters allowing the dry powder to be released under pressure over a wide area.

•Fully refillable
•Complete with roof mounting bracket
•Activation Temp is 68 ºC = 154.4 ºF
automatic powder extinguisher
Play safe everyone }

Electrical & safety

How do I convert watts to amps and amps to watts?

The formula for converting Watts to Amps is : Watts = Amps * Volts

The formula for converting Amps to Watts is : Amps = Watts / Volts

SAFTEY WARNING : Only use 80% of the circuit breaker capacity!

Common Conversions North American and other 110 volt countries

Lights :
1000W / 110V = 9.1A
600W / 110V = 5.4A
400W / 110V = 3.6A
250W / 110V = 2.3A

Circuits :
10A * 110V = 1100W and 80% safe usage is 880W
15A * 110V = 1650W and 80% safe usage is 1320W
25A * 110V = 2750W and 80% safe usage is 2200W
30A * 110V = 3300W and 80% safe usage is 2640W

Common Conversions British Commonwealth and other 240 volt countries

Lights :
1000W / 240V = 4.1A
600W / 240V = 2.5A
400W / 240V = 1.7A
250W / 240V = 1.1A

Circuits :
10A * 240V = 2400W and 80% safe usage is 1920W
15A * 240V = 3600W and 80% safe usage is 2880W
25A * 240V = 6000W and 80% safe usage is 4800W
30A * 240V = 7200W and 80% safe usage is 5760W

Remember that a circuit services more than one power outlet.
A two outlet wall plug will use only one circuit.
There will be more outlets on 240V systems per circuit than there will be in 110V systems.

Fire Escape Plan
Fire can be very frightening, but don't worry, I'm going to help you make your own
Fire Escape Plan.
If a fire starts in your home you will be scared, but try very hard to stay calm.

Having a Fire Escape Plan, so you know what to do if there is a fire,
could save your life.
Fire Plan part 1

If you are woken up by the sound of your smoke alarm or by the sound of what you think is a fire, remember:


Stay calm. Wake all the members of your family.
Make your way out together, through the nearest exit.
Do not open any doors other than the ones you need to escape through.
If a door feels hot DO NOT open it.
When everyone is safely outside call the Fire Service .
DO NOT GO BACK TO THE HOUSE for any reason until the Fire Service tell you it is safe to return.
If the fire is blocking your way or you cannot use the stairs for any reason, you must use the second part of your Fire Escape Plan.

Fire Plan part 2

In fires there is sometimes a lot of smoke. This can kill you. If you have to go through a smoke - filled hallway or room, get down on your hands and knees and crawl under it.

Get all the family into a room from where it would be safest to drop from a window, onto a flat roof or into the garden.
ALWAYS pass children down first. Never leave children until last.
Remember - never jump!
Lower yourself to arms length and then drop.
When everyone is out safely, find a telephone and dial 999.
If you are trapped by smoke and cannot escape through a window, use part three of your Fire Escape Plan.
Fire Plan part 3

If you are trapped in a room by smoke or fire, you need to try to stop smoke getting into the room.

Close the door.
Block any gaps into the room. Use towels, blankets or spare clothes.
If there is a telephone in the room dial 999.
If there is no telephone, go to the window and shout for help.
Once you know you have been heard and help is on the way, stay near to the floor by the window. Smoke and heat rise so you are safer near to the ground.
If your windows are double glazed, use a heavy object and hit the window in a bottom corner. Make any jagged edges safe with a towel or blanket.

How to Put Out an Electrical Fire
Many people think they are prepared for a fire, but there are different kinds of fires and not all of them can be treated the same way. Just because you have a fire extinguisher in your home, doesn't mean you can use it to combat any fire. Electrical fires are one type of fire that must be attacked in a precise way in order to put out the flames quickly and safely.
Shut off the main breakers to the house, know where your fuse box is if possible
First priority is to remove the source of the electricity or the fire will continue to form.
After disconnecting the electrical source, you can use water , that's what the fire brigade/service will use also .
If you cant disconect the electrical supply use a dry powder extinguisher CO2 extinguisher, or Sand
General rule: If a fire has taken hold, (spread to other areas or structures or the smoke is at head height), all occupants of that building must be evacuated. Note to all: Do not fight a fire not worth fighting, evacuate the building, personal safety comes first.
Turn off all power to the fire, usually done by turning off the main power. This step alone is usually enough to stop most fires in the initial stages.
Use a safety blanket to smother the fire (Remember: If you do not turn off the power supply, electric shock is likely to occur.). Not only is this very effective in the early stages but does not damage surrounding area or objects.
#4 if you isolate/switch off the electrical supply
Use water (more than two liters at a time) to extinguish the fire, throw the water at the base or seat of the fire. This is also very effective.(Remember: If you do not turn off the main power supply, electric shock is likely to occur).
The safest and the best way to extinguish a electrical fire is to use a fire extinguisher. Follow the instructions on it for more information. Note: During the initial stages of fire, once the fire is put out the surfaces that it has touched or burned are very hot and are likely to catch fire. You must have enough extinguishing material for at least 7 extinguishing attempts. E.G. 6Kg dry powder fire extinguisher. (Remember: If you do not turn of the mains power supply, electric shock is likely to occur.)
General rule: Aim the extinguisher nozzle at the base or seat of a fire for most effective extinguishing of fire.
A torch beside the fuse/breaker box is a good idea .
Play safe everyone

Good advice on here! I would add use trip switches and power breakers too, a must imo.

Thank's kindly ..
Next to the breaker or fuse box or bedside .
Safety first everyone play safe .
If you cannot isolate the electrical supply and need to feel you'r way because of smoke use the back of you'r hand as electrical shock will contract muscles making you grab onto .
All input welcome .
Respect .
