If your company is planning an expansion, retro-fit, grass roots facilities, or simply modifying a process unit, and the process hazard analysis (PHA) indicates you need a safety instrumented system (SIS) as a protective layer, then you need to comply with ANSI/ISA S84.01. Why? Because in February 1996, the “Application of Safety Instrumented Systems for
Many facilities believe putting a flange together is far easier than paying for a “certified weld” joinment. They see this as a low-risk, cost-saving solution, believing any “maintenance mechanic” can put a flange together. Hence, most LOPC events I have had in my time were due to a flange that was NOT assembled per ASME
This was a new pressure vessel that failed during its hydro test following its fabrication. The vessel’s Post Weld Heat Treatment was not properly conducted, when some parts of it did not reach the required temperature. Coupled with a small hydrogen crack, the failed post weld heat treatment was sufficient to cause catastrophic failure while
First, let’s define what this article is all about. Has your facility ever had a leaking flange? Just a tiny drip of liquid or a small release of gas? What is the most common response to this leaky flange? Someone goes out and tightens the flange bolts to stop the leak. This practice is done
RMPs MUST be updated at least once EVERY five (5) years. Owners and operators responsible for RMP implementation should review the factsheet A Checklist for Submitting your Risk Management Plan (pdf). This factsheet provides a checklist to consider in updating and resubmitting RMPs. Use EPA’s RMP*eSubmit for your resubmissions. For additional information see the RMP*eSubmit Users’
Under the Clean Air Act, Section 112(r), the EPA established a program requiring facilities possessing greater than certain threshold quantities of 140 chemicals to provide risk management plans to the EPA.1 As part of this reporting requirement, facilities are required to determine the worst-case scenario release from a single chemical process, using EPA criteria and guidelines.2 Facilities
It cannot be assumed that workers will naturally begin to report problems, errors, and near misses once a just environment is in place. There are a number of organizational as well as psychological barriers that must be hurdled before a reporting culture can be put in place. The first barrier to overcome is
In older facilities, we see illumination for an exit sign coming from an external source. Section 1013.6 of the IBC regulates the graphics, illumination, and emergency power supply for such signs. Although no particular color is specified for exit signs, it is REQUIRED that the color and design of the signs, the lettering, the arrows,
Three (3) ingredients are vital for driving the safety engine, all of them the province of top management or what the organizational theorist, Mintzberg, has termed the strategic apex of the system. These driving forces are: commitment, competence and cognizance Reason’s three C’s.
Verifying that grounding and bonding systems meet a specific resistance threshold—such as the common 10 ohms target for flammable liquid processes—requires a systematic approach to ensure both accuracy and technician safety. The following procedure outlines the steps for performing a static ground-resistance test using a dedicated ground-resistance tester (Ohmmeter). This procedure applies to the periodic
Take any of the following steps below that may be necessary to guard against stored energy(s) left in the equipment after it has been shut down and isolated from its energy source(s).
