Definitely yes, because you do not know when your employee will face problem or hazard at work with the experience of first aid he or she will treat himself or herself before it become worse when he or she get to the hospital for proper treatment
It might be hard to train employees who have no training at all in this regards. Getting trained when it comes to using first aid kit could be complicated as many people might panic in such kind of situations in case of emergency. But I still think that this kind of training is important.
