API STD 2220:2011

Contractors perform greatly varied work within the petroleum and petrochemical industries. Some perform construction and turnaround activities or drilling and well servicing; specialty contractors provide skills and services that are not typically found within an owner's work force. Contractors may even provide services that augment the peak loads and skills of owners' work forces, such as in the maintenance and operation of facilities. Since owner sites and contracted work are diverse, this standard may not be applicable to all operations at each company or to all contract work performed in those operations. As such, this publication may not apply to incidental contractors that generally do not affect facility safety, such as those that provide janitorial, laundry and delivery services. This document addresses 'conventional' safety and health. It does not address safety concerns associated with security or terrorism issues.
