To analyze the worst-case release scenario required as part of the hazard assessment at 40 CFR Part 68, Subpart B, the worst-case release quantity is identified as the greatest amount held in a single vessel or pipe, taking into account administrative controls that limit the maximum quantity (40 CFR §68.25(b)). Are mechanical controls such as […]
How close must a stationary source be to a weather station in order for that station’s data to be applicable to the stationary source?
The implementing agency will, according to the regulations at 40 CFR §68.220(b), select stationary sources for audits based on any of the following seven (7) criteria:
Competence is defined in ISO 45001:2018, 3.23, as “the ability to apply knowledge and skills to achieve intended results”. Competence enables a person or organization to act effectively in a job or situation. It is acquired through training, education, experience, or a combination of these, as determined by the organization. Workers whose activities affect or
As we have discussed, OSHA does not have a “flammable gas” standard for those flammable gases outside the scope of its Liquefied Petroleum Gas (LPG) standard 1910.110. So in most of my work with flammable gases, I will use 1910.110 or NFPA 58 as my RAGAGEP. I do this as many facilities already have some
It is difficult for engineers to change human nature and therefore, instead of trying to persuade people not to make errors, we should accept people as we find them and try to remove opportunities for error by changing the work situation — that is, the plant or equipment design or the method of working. Alternatively,
I have been surprised at our profession’s lack of basic understanding regarding pressure and vacuum. I think most people of the general public have no idea that we live under 14.7 pounds of pressure per square inch on our bodies. We say this is what it is at SEA LEVEL, which means a lot. As
The incident occurred shortly after 4:30 am on January 23, 2020, when an accidental release of propylene accumulated and exploded inside the building. The CSB found that before the incident, a hose disconnected from its fitting inside a coating booth and released propylene, a flammable hydrocarbon vapor, which accumulated inside the coating building. When employees
If you want to have some fun VALIDATING the Hazard Identification element of your SMS/Safety Process, use some of these cartoons or real images in a fun but eye-opening exercise. Get a group together, show the cartoon/image, and have the group (but individually) identify all the hazards they can recognize in the cartoon/image. Then we
As I rant on about validating and verifying our safety data and defining and quantifying our safety processes, I wanted to share another incident where we learned the hard way. I managed a chemical facility with many corrosives; thus, eyewashes and safety showers were important items in the mitigation layer. And as most of us
Whether it is on leading or lagging data, data validation and verification is a MUST if we want to build a solid SMS. Making decisions on bad (unverified/unvalidated) data leads to bad decisions, or worse – inaction in risks as leadership may believe all is well.
