Having the correct supplies can make a big difference in an emergency, so you should always keep a selection of essential first-aid materials at home and in your car. Store the items in a first-aid box or in a similar type of airtight container in a dry place. The box should be easily accessible in an emergency but kept away from other medicines and out of reach of children. Ideally, the box should be small and light enough for you to carry easily. Check and replenish the first-aid kit regularly so that the contents are kept up to date.
