 Qualified Person – a person who, by possession of a recognized degree or certificate of
professional standing, or who, by extensive knowledge, training, and experience, has successfully
demonstrated the ability to solve or resolve problems relating to the subject matter and work.

within the rated load limit, or uniform loads less than 65% of rated load for not more than 15% of

5.2 Inspection Classification
5.2.1 Initial Inspection – prior to initial use, all new, altered, or modified hoists shall be inspected by a
designated person to ensure compliance with the applicable provisions of this manual.
5.2.2 Inspection Classification – the inspection procedure for hoists in regular service is divided into two
general classifications based upon the intervals at which inspection should be performed. The intervals
in turn are dependent upon the nature of the critical components of the hoist and the degree of their
exposure to wear, deterioration, or malfunction. The two general classifications are herein designated
as FREQUENT and PERIODIC, with respective intervals between inspections as defined below.
5.2.3 FREQUENT Inspection – visual examinations by the operator or other designated personnel with
intervals per the following criteria:
 Normal service – monthly
 Heavy service – weekly to monthly
 Severe service – daily to weekly
 Special or infrequent service – as recommended by a qualified person before and after each
occurrence.
5.2.4 PERIODIC Inspection – visual inspection by a designated person with intervals per the following
criteria:
 Normal service – yearly
 Heavy service – semiannually
 Severe service – quarterly
 Special or infrequent service – as recommended by a qualified person before the first such
occurrence and as directed by the qualified person for any subsequent occurrences.
