Victor Dearman Jr. CIRO, CRST No, it doesn’t involve anything with refrigeration. Same equipment, the same people, and a better layout to improve efficiency. So why would an MOC be required if it doesn’t impact refrigeration/PSM? Well, we have to think a little beyond equipment changes in the refrigeration system for a moment, or procedural changes, etc. that we normally think about. And...

Many workplaces struggle with one of the most critical elements of any attempt to manage safety and health via a safety management system – Incident Investigations. From the struggles of getting personnel to REPORT incidents (including near misses) to management recognizing these reports are GIFTS handed to us! But what normally happens, is we get employees reporting and we lose a lot of credibility...

I like the fact the thieves wore “high vis” clothing to make themselves look “legitimate”. But as the story points out they were getting injured in arc flash events. I support Hi Vis workwear, as it can’t hurt to be more visible in a busy workplace, especially with a lot of mobile equipment around. My issue with high-vis requirements is that far too many think it’s some type of visible...

This is another Top 10 question on flammable liquids safety I get from clients, cold calls, referrals, and friends. Most are familiar with the testing limits for path to ground on bonding/grounding stations of 10/25 ohms. In my previous post tonight I explained where these 10 and 25 ohm limits came from and how they are essential very LARGE SAFETY MARGINS for our systems. When we look at NFPA 77 (2024)...

Theoretically, a resistance to ground of 1,000,000 ohms is considered capable of dissipating a static electrical charge. So why then does my safety program (and NFPA 77) require a resistance to ground of 10 or 25 ohms OR LESS, depending on the metal used in my system? (e.g. end-to-end resistance of a bonding wire should be less than 10 ohms for COPPER and less than 25 ohms for STAINLESS STEEL) Well,...

Volume 2 covers 25 serious chemical incidents in 14 states: Arkansas, Alabama, California, Colorado, Connecticut, Illinois,  Louisiana, Mississippi, Nebraska,  Nevada, New Mexico, Ohio, Oklahoma and Texas.  These serious incidents resulted in 7 fatalities, 23 serious injuries, and approximately $1 billion in property damage.

On January 7, 1983, at approximately 12:15 am EST, a massive explosion, ignited by an overflowing gasoline storage tank at the Texaco storage facility in Newark, NJ, and a nearby incinerator, destroyed three tanks, killing one person and injuring 24, while the blast was felt up to 100 miles away. Cause:The explosion was said to be caused by a human error; specifically, workers failed to monitor a pipeline...

Providence Fire Department Field Notes Date: 26Dec2024 Time: 15:04 Address: 130 Terminal Rd Incident No.: 2024-45273 Investigator: Eric Pedro SUMMARY  On December 26, 2024, at approximately 15:30 hours, Fire Investigators from the Providence Fire Department responded to 130 Terminal Road to conduct a fire scene investigation.  Investigators determined the fire originated in a distribution tank...

Gasoline (UN1203) is a NON-conductive flammable liquid. These liquids, as all liquids, generate static electricity as they flow through hoses, piping, and free fall into tanks and containers. Since the liquid is non-conductive, it can not conduct the static charge to the hose/pipe/container so the charge can be dissipated to the “ground”. Authorities say quick work by staff helped ease...

Nine (9) grain dust explosions in 2024 in the USA caused two (2) injuries and NO fatalities. These numbers are similar to last year’s (nine explosions, 12 injuries, and no fatalities) and on par with the 10-year national average of 8.6 explosions. The explosions occurred in: … HomeRead More »

Many folks will focus on ONLY three (3) criteria for applying this “exception” to OSHA LOTO standard 1910.147. And these (3) criteria are just opening the gates to LOTO Hell. Far too often we find the “exception” has become the rule and LOTO has become the exception. So what are the FIVE (5) criteria we need to meet to SAFELY apply this “exception”: Note: Exception...
