According to the American Petroleum Institute, a turnaround is a planned, periodic shutdown (total or partial) of a refinery process unit or plant to perform maintenance, overhaul and repair operations and to inspect, test and replace process materials and equipment. With a turnaround comes an often increased workforce requiring gas detection to keep them safe from gas hazards including oxygen deficiency, combustible gases (typically displayed as LEL), carbon monoxide, hydrogen sulfide, sulfur dioxide and VOCs.
To meet this need, companies are faced with making a decision: should they buy or rent portable gas detection equipment?
