Be sure to burn the trash in appropriate weather conditions. You will not want to burn trash in windy or humid conditions because it can be a fire hazard. For burning trash safely, it will be wise to wait for a calm day.
Contact the fire department and make them aware of your intentions to burn trash. Seek their advice to determine if prevailing climatic conditions are safe for burning trash. The fire department will not make an unnecessary emergency run to your home if they are aware of your plans ahead of time.
To prevent the flames from spreading, burn the trash in a fire barrel. If that is not possible for some reason, make a fire pit. Remove any flammable materials such as clutter and weeds from the area surrounding the fire pit or the fire barrel in which you are going to burn the trash.
To cope with a hazardous situation that may arise due to the fire burning out of control, keep a bucket full of water and a shovel nearby.
Closely watch the fire as long as it is burning. When the fire dies out, take care of the coals by pouring water on them. Leave the area only after the ashes properly cool down.
