OVERVIEW 3 M Mand ndatory c y cha haracteristics o of a a C Conf nfine ned S Space 1. Be large enough for a worker to enter it. 2. Not be intended for regular continuous entry. 3. Be difficult to enter or exit Even if just your head Permi mit f for C Conf nfine ned S Spaces is in the space…. 1. Not a building or construction Permit 2. Specific to a work site 3. Keep on file at your business and at work site
