Process Safety Life-cycle Capabilities

Industrial environments pose unique risks to the safety and wellbeing of employees and the surrounding community and environment. Safety Instrumented Systems (SIS) play an essential role in providing a protective layer around industrial process systems. Its purpose is to identify a specific hazard when pre-determined set points are breached and take the process back to a “safe-state.”

Hargrove provides the full range of SIS design and implementation services. From building new systems, studying legacy systems, and recommending the most impactful safety changes, our Team can help ensure your facility meets regulatory requirements and adheres to the latest industry best practices.

Hargrove performs hazard and operability studies (HAZOP) and layers of protection analyses (LOPA), participates in design reviews, calculates probability of failure on demand (PFD), performs criticality analyses, and tests on new systems. We help our clients design, install, and maintain “failsafe” control systems for the full Safety Instrumented Function (SIF) – logic, actuators, sensors, and other control equipment independent of your basic process control system to ensure SIS functionality is not compromised.

Our Team is experienced in a variety of SIS platforms:

  • HIMA
  • Schneider Triconex
  • Emerson DeltaV SIS
  • Rockwell AADvance and GuardLogix
  • Honeywell Safety Manager
  • Honeywell Fail Safe Controller (FSC)
  • Yokogawa ProSafe, Siemens Step7 Safety
  • Siemens (Moore) QUADLOG

Safety Compliance

The General Duty Clause section 5(a)(1) of the Occupational Safety and Health Administration (OSHA) act requires all employers to provide a workplace free from recognized hazards that cause or are likely to cause death or serious injury. This general statement of responsibility is imperative for OSHA compliance yet new and changing safety standards leave how to satisfy the specific requirements ambiguous, especially for the industrial process industries.

Establishing a Process Safety Management (PSM) program for compliance requires qualified experts in OSHA recognized international safety standards including IEC 61508, IEC 61511 / ISA 84, and IEC 62061. Beyond instituting a PSM program, maintaining and testing safety systems and practices should be an ongoing process to ensure that the safety processes and systems function as intended over their operational life.
