The General Duty Clause section 5(a)(1) of the OSHA act requires that all employers provide employees with a workplace that is free from recognized hazards that are causing or 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.
Implementing and maintaining a PSM program for compliance requires expertise in OSHA recognized international safety standards including IEC 61508, IEC 61511 / ISA 84, and IEC 62061.
The Role of Safety Instrumented Systems in Industrial Facilities
Industrial environments pose many 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."
Whether working on upgrading an industrial facility or building a new greenfield facility, designing, installing and maintaining “failsafe” control systems and instrumentation is of the utmost importance. Establishing a Process Safety Management (PSM) program requires qualified experts in industrial safety systems and regulatory compliance. 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 its operational life.
Hargrove’s Safety Culture protects and promotes the wellbeing of each person who works with us and each person touched by our work. Hargrove’s SIS Specialists and Process Hazard Analysis (PHA) facilitators are seasoned and highly-trained, having completed the industry’s most rigorous and comprehensive Functional Safety Training Program to earn certification as TÜV Rheinland Functional Safety (FS) Engineers.
Our Team has many years of experience in the practical application of industry standards; we design and implement safety systems in the process industries daily (refining, petrochemicals, chemicals, oil and gas, and manufacturing). With senior members of our Team participating members of safety standard committees, we have a thorough understanding of industry standards and stay abreast of the ever-evolving regulatory requirements. Our Certified Functional Safety Engineers have developed a meticulous methodology for process safety, adhering to IEC 61508 / 61511, ANSI/ISA-61511-2018, and the entire Safety Lifecycle.
From building new systems, studying legacy systems, and recommending the most impactful safety changes, our team works with you to meet your safety needs. The Team at Hargrove includes:
- Process design engineers
- Electrical and instrumentation engineers
- Electrical and instrumentation designers
- Control system engineers
