When we are reading RAGAGEPs for Chlorine Process Design, we will certainly see references to “Wet Chlorine” and “Dry Chlorine,” and it’s one of the top questions I get when people/businesses are new to the chlorine business. In the world of process safety and metallurgy, the distinction between Dry Chlorine and Wet Chlorine is one […]
Since 2003, the International Fire Code has offered an “alternative” to complying with all the special hazard chapters of the “code”; it’s called the Performance-Based Design Alternative (PBDA). This alternative was intended to provide some relief to facilities that are already doing PSM/RMP style activities for their hazardous material(s) and to provide an IMPROVED alternative to
Each employer must address actions that workers will take when there is an unwanted release of highly hazardous chemicals. Employers will need to decide: if they want workers to handle and stop small or minor incidental releases; whether they wish to mobilize the available resources at the plant and have them brought to bear on
NH3 gas is COLORLESS! Check out the SDS or any data source if you think I’m kidding. What we are seeing in that “white smoke” or “cloud” is moisture in the air (i.e., humidity) condensing on the very cold NH3 gas. So the question I often get is: How much NH3 gas is needed to
Recent reports published by the National Academies Press provide conclusions and recommendations for improving acute exposure guideline level (AEGL) documents for several chemicals and chemical classes. AEGLs were developed by the National Advisory Council to provide values with which to assess acute adverse health effects for extremely hazardous substances (EHSs).
I wish all the states made compliance this simple! Well done MI.
Approximately 90 percent of hazardous materials (hazmat) injuries are due to inhalation. In general, although some solids are highly hazardous (upon physical contact with the skin or if ingested into the body), gases and liquids with high vapor pressures pose the most significant risks to responders. These chemicals are more hazardous because they can become
On July 13, 2012, EPA modified the EPCRA Section 312 Emergency and Hazardous Chemical Inventory Forms (Tier I and Tier II) to add new mandatory and optional data elements under the facility identification and contact information sections of both forms. EPA also revised some existing data elements on the chemical reporting section of the forms
Cylinder Colors While the cylinder label is the primary means of identifying the properties of the gas in a cylinder, the colour coding of the cylinder itself, can often time provide a further guide. Cylinder Shoulder – European Standard Color CodingThe color applied to the shoulder, or curved part, at the top of the cylinder,
For nearly 16 years I have seen clips of a “dashcam” video that claims an NH3 transportation accident (w/ nurse tank) claimed the life of an IL State Trooper. The video is on dozens of websites and we even see it used in training courses and almost always the video is depicted as being real
FRA is issuing Safety Advisory 2012–01 to remind shippers and consignees of railroad tank cars containing odorized liquefied petroleum gas (LPG), of the importance of taking actions to ensure that a sufficient level of odorant remains in the LPG throughout the entire transportation cycle. FRA is issuing this notice to raise awareness within the hazardous materials community,
The NIOSH Respirator Selection Logic (RSL) relies entirely on whether the airborne concentration of a contaminant exceeds a defined exposure limit (such as the NIOSH Recommended Exposure Limit [REL] or OSHA Permissible Exposure Limit [PEL]), regardless of what the chemical’s vapor pressure is. However, vapor pressure plays a decisive role in selecting a respirator, particularly
