“In addition to installing CO detectors, every hotel should establish preventative maintenance schedules to properly maintain and inspect CO emitting equipment and their ventilation systems. They should also provide the necessary training education to their staff and especially their maintenance staff. Hotels should have knowledgeable engineers on staff and contract out maintenance of HVAC systems. Hotel franchisors need to fully understand the risk of CO poisoning and take a proactive stance to protect the guests who are sleeping in their hotels.”
