Like most of the beautiful things in life, horses are beautiful and lovely creatures. To deal with them you would need to take some precautions. There are no instances of horses intentionally hurting someone or another animal, but like it's rightly said accidents do take place. They say prevention is better than cure!! Like wise it is a good idea to know how to avoid such situations even before they could occur.
Slip and falls are a common way to get hurt inside the barn so always put all equipment away and remember to keep objects that do not belong where a horse can get them out of his reach so the both of you can have a safe time inside the barn.
Cleaning the barn is an essential part of safety for both you and your horse, this should be done on a daily basis along with wearing the correct outfit for working inside a barn, one of most important is footwear, never wear open shoes.
Getting kicked by a horse is no fun so whenever your working around the horse it is important to be aware of the space between the two of you and if you have to work in the area to the rear of the animal you should stay very close to the horse so you can prevent the horse from being able to really kick you.
Do not allow the animal to get into the barn by itself. Always lead your horse to the barn. It is a good idea to train your horse for this so that it becomes safe for other people or animals present at the time the horse starts kicking in the barn. While taking the horse into the barn try using a lead rope for this purpose rather then using a halter. Using a lead rope will give you more control. While doing so, keep in mind not to hook your fingers through the halter straps or rings. There are chances of your fingers getting caught and injured if the horse tries to pull away.
Most of time people get hurt around horses it is because the horse was spooked and was attempting to get away from whatever spooked it, so always remember when handling your horse or even just watching a horse to take basic safety precautions.
Always keep your animals separate. Avoid placing them alone in a closed place. This is simply because animals need not necessarily get along well with each other. They could get restless and this could make the situation hazardous for you and the other animals.
Safety is of critical importance for the both of you so try to memorize the safety advice given here and use it all the time, this way you will have a safe and enjoyable time with your horse.
