Layered Protection with Safety Instrumented Systems

Layered Protection with Safety Instrumented Systems

The safety of your facilities depends on many layers of protection working together. Safety instrumented systems often are your last line of defense in protecting your employees and the public.

Burns & McDonnell offers turnkey solutions and experience that will help you meet the latest process safety standards and put safety front and center.

Safety Now and Always

Safety instrumented systems (SIS) in your facilities make good sense at any time, but complying with the Occupational Safety and Health Administration's Process Safety Management Standard makes now the best time.

Using a tolerable risk-based approach, we can help you apply the concepts of SIS to environmental and asset protection. Turnkey SIS solutions from Burns & McDonnell can be installed during regularly scheduled maintenance. A properly designed SIS means safer workers, increased productivity and greater profits.

Beyond compliance, SIS installations monitor your production processes and make automatic corrections should they become unsafe. SIS can benefit many types of facilities, from oil refineries and chemical plants to biofuels plants and pulp and paper mills.

SIS Experience

Burns & McDonnell has delivered SIS solutions for more than a decade. Our in-house resources include all disciplines necessary to design and construct a system that fits your unique needs. Using engineer-procure-construct delivery, we can take your project from conception to acceptance testing and startup, ensuring it delivers the safety and efficiency you need.
