I was the safety officer for a large construction company. With several first aid kits to keep track of and the soaring costs of supplies I found this particular kit to be perfect for use. Interchangeable, all components fit in the same places, parts and pieces did not fall out when opened. Immediate inventory. A quick and easy reorder tab for the hands to turn in when something is needed. Yep this kit worked perfectly. Now int he oil and gas industry I am seeing this type of kit works for all the same reasons listed earlier.
However, Grainger take note. Make the reordering of parts easier. Right now they are difficult to find on line.
