In the world of pressure vessels (like those governed by ASME Section VIII), the terms “stress relieved during fabrication”, Cold-Formed Heads, and Hot-formed Heads relate to heat, but they are very different techniques used in PV construction. PWHT is about treating the material after it’s been worked, while “hot formed heads” is about shaping the […]
UPDATED 5/2016 Each year more and more states are adopting International Codes. The chart below is a list of all states and US Territories that have adopted these codes, the code edition they adopted, whether the code is enforced state wide or local governments, etc. This listing is up-to-date thru September 2015. Are you complying
The North Dakota Industrial Commission has adopted new conditioning standards to improve the safety of Bakken crude oil for transport. Order No. 25417 sets operating standards for conditioning equipment to properly separate production fluids into gas and liquid. The order includes parameters for temperatures and pressures under which the equipment must operate to ensure that
The maximum allowable quantity per control area is specified in Tables 5003.1.1(1) through 5003.1.1(4) of the IFC. Tables 5003.1.1(1) through 5003.1.1(4) establish the maximum quantities allowed in a control area (see Section 5003.8.2 for design and protection requirements). If the quantity of chemicals used in a building does NOT exceed the maximum allowed per control
Over the years I have posted several articles about hazardous materials being unloaded to the wrong tank. And it seems that each time I do I get several e-mails stating how rare these events are and that I am being an alarmist. So I thought I would post a section of a PHMSA Investigation Report
Propane cylinders must be periodically requalified to be safe for use. Do not use cylinders that have not been requalified because you risk property damage, severe injuries, or death. To see if your cylinder is okay to use, look for these markings:
PHMSA is amending the Hazardous Materials Regulations to maintain alignment with international standards by incorporating various amendments, including changes to proper shipping names, hazard classes, packing groups, special provisions, packaging authorizations, air transport quantity limitations, and vessel stowage requirements. These revisions are necessary to harmonize the Hazardous Materials Regulations with recent changes made to the

In every 24-hour HAZMAT course, we teach, we find that students getting their first official dose of “chemical safety” are shocked to find out that most gases at their facility are NOT white in color. Most have seen dozens of videos over their adult lives showing these large white clouds forming during releases of hazardous
For many HAZMAT students, learning that a HAZMAT shipped as a Non-Flammable Class 2 HAZMAT can actually ignite is a sobering fact of emergency response. But when they find out this HAZMAT is anhydrous ammonia (NH3) there is a level of disbelief. But it was this week 30 years ago (9/17/84) at approximately 4:00 p.m.,
