If my bonding/grounding system’s resistance to ground needs to be <10/25 ohms, then why is ESD footwear allowed a resistance of 1,000,000 ohms?

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 […]

If 1 meg-ohm is adequate resistance to ground, then why do we test to 10 or 25 ohms?

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

The CSB releases Volume 2 of its Incident Reports

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. Link to Volume 2: http://www.idevmail.net/link.aspx?l=1&d=86&mid=421120&m=2672 The reports give the public important information about

1983 Newark 1.8 Million Gasoline Storage Tank Explosion

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

Static electricity from flowing gasoline?

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

Hazard ID is fundamental to any SMS and an ALJ who gets it

Sometimes a lawyer or set of lawyers can surprise us… This is a quote from a recent OSHRC ALJ decision, regarding the employer’s responsibility to conduct inspections of the workplace to identify and correct hazards: “As an employer, Respondent is obligated to provide safe working conditions and ensure safe work practices. Implicit in that obligation

LOTO Safety Myth #1

I have written dozens of articles around these “safety myths”, but Jonathan Zimmerman and I were not selected to present this at ASSP several years ago so I thought I would share it as a series here. These are topics that I still get challenged on in 2024/2025 and often I am unable to convince

[My] Safety Thought of the Week… Culture of Safety

The recent news from Boeing’s CEO regarding their cultural challenges reminded me of a discussion I had with one of my favorite plant managers, Dale Fannin, in 1996. It was an uncomfortable discussion, as I had my a_s handed to me, regarding all my “cheerleading” rather than being a safety leader. Dale, as were two

When will the ammonia refrigeration industry finally embrace LOTO? (Part II)

Victor Dearman Jr. CIRO, CRST One of the challenges to my post was “What if the flagging tape was to indicate that the valve was in an abnormal position?” This was followed up with a challenge as to whether or not anything forbids such a method. Operating procedures should be designed to meet the requirements
