It is important that a suitable first aid kit for work is chosen and that there is enough there. You can look online for different types of kits, type in business first aid kit, or industrial first aid kit and you can see a lot of examples. Then you just need to choose kits that have enough supplies for how many people working there. For example something for 10 employees or less, 25 employees or less and so on. The kind of kit you would as an employer put in the office where your office workers are, is different to what you would put in the warehouse or in work vehicles.
