15. protect strategic assets for private enterprise. Automatic shutoff systems are the only real protection for many customers. The natural gas and propane industries use a smell warning system to warn their customers about potential gas problems. However, automatic protection systems secure your facilities without human aid. Layered specifications compensate for these vulnerabilities, adding to the strengths of the existing odorization system.
Human limitations restrict the reliability of existing systems.
Many people cannot or will not learn to smell warning odors. And if they do smell the odor, and correctly identify it, many will not report it. There are NO other odors or processes which will significantly improve the safety of performance of gas systems through odorization. New, layered protection systems are needed to bring deeper protection to those customers who require it. Reliability New automatic shutoff systems for natural gas and propane are very reliable, are certified by the Canadian Gas Association and the American Gas Association, and regulated by ISO 9000 Quality Assurance processes.
