Trench Warning from OSHA

Monday, October 10, 2011

Two workers are killed every month in trench collapses. Unprotected trenches are among the deadliest hazards in the construction industry and the loss of life is devastating.Since 2003, more than 200 workers have died in trench cave-ins and hundreds more have been seriously injured. OSHA has three new guidance products to educate employers and workers about the hazards in trenching operations.

The new products include a fact sheet, QuickCard and a poster that warns, “An Unprotected Trench is an Early Grave.”

The three documents may be ordered in English- and Spanish-language versions from the Publications page of OSHA’s web site. See the news release for more information.

Trench Collapse Fatality: Las Vegas, NM

Friday, June 03, 2011

What does getting struck by a pickup traveling 45 mph and being in the path of a trench wall collapse have in common? The outcome is typically not going to be positive…

A six cubic yard section of trench wall that collapses into an 8 foot deep trench has the weight and speed of a full size pickup traveling 45 mph.

These forces are the reason why a proactive and compliant trench safety program is paramount to your safety as a worker or as a rescuer!

Unfortunately, there was another tragic incident last week in Las Vegas, New Mexico, in which two workers were killed following a trench cave-in. Dirt buried 49-year-old Frank Romero and 32-year-old Gene Hern. The men were installing sewer and water lines in the 8 to 10 foot deep trench. City spokesperson Dave Romero says other workers frantically tried to dig the men out but didn’t make it to them in time. Hern and Romero were pronounced dead on the scene by medical officials.

This serves as another reminder of how important it is to be trained in the proper precautions and dangers of trenches and excavations. Once it happens, it’s too late, there’s no time to prepare. As a first responder, be aware when this type work is going on in your district or response area – don’t take chances, know how to protect yourself. And, if you’re involved with the project from the beginning, preplan each job with the utmost precaution.

According to OSHA, excavation and trenching are among the most hazardous construction operations. This type work presents serious hazards to all workers involved. Cave-ins pose the greatest risk and are much more likely than other excavation-related accidents to result in worker fatalities. Other potential hazards include falls, falling loads, hazardous atmospheres, and incidents involving mobile equipment. The regulation that covers requirements for excavation and trenching operations is OSHA 1926.650.

What’s the difference between an excavation and a trench?
OSHA defines an excavation as any man-made cut, cavity, trench, or depression in the earth’s surface formed by earth removal. This can include excavations for anything from cellars to highways. A trench is defined as a narrow underground excavation that is deeper than it is wide, and no wider than 15 feet (4.5 meters).

Why is it important to preplan the excavation work?
No matter how many trenching, shoring, and back-filling jobs you have done in the past, it is important to approach each new job with the utmost care and preparation. Many on-the-job accidents result directly from inadequate initial planning. Waiting until after the work has started to correct mistakes in shoring or sloping slows down the operation, adds to the cost, and increases the possibility of a cave-in or other excavation failure.

A big part of being safe, is being prepared. Knowing as much as possible about the job or work site and the materials or equipment needed is a best practice. Here are a few things OSHA recommends you consider about the site.

        1. Traffic
        2. Proximity and physical conditions of nearby structures
        3. Soil
        4. Surface and ground water
        5. Location of the water table
        6. Overhead and underground utilities
        7. Weather  conditions

OSHA Excavation and Trenching Standard applies to all open excavations made in the earth’s surface, including trenches. Strict compliance with all sections of the standard will greatly reduce the risk of cave-ins as well as other excavation-related accidents. See the resource below to learn more.

In the Trenches with Santa Fe Fire Dept

Tuesday, October 19, 2010

We received this great email and photo from Jan M. Snyder, Battalion Chief for the City of Santa Fe Fire Department. Thanks for the feedback, Chief!

“I want to thank you for all your help and coordination this year with all the City of Santa Fe Fire Department has done with ROCO. Last week’s Technical Trench class was a huge hit, the guys loved it and Tim, Rich, and Brent were great. The quality of the ROCO programs and instructors has never failed us and we look forward to further training opportunities in the future.”

OSHA Sites Company Following Trench Death

Friday, August 13, 2010

Driving around your town, how many times have you seen workers in a trench working totally unprotected?  As an emergency responder, are you aware of the imminent dangers around these trenches and do you know how to protect yourself should you respond to one of these incidents?

Trenches can collapse without warning entrapping and surrounding a victim in seconds – making it impossible to breath. Most trench cave-ins occur in good weather, and it has been  reported that up to 70% of fatalities occur in trenches less than 12 ft deep and less than 6 ft wide. Failed trenches have a 100% chance of secondary collapse…it’s just a matter of time.

Just a few things to think about…
  • 1 cubic yard of dirt moving 6 ft will reach an impact force equal to 45mph.
  • 2-feet of soil on a person’s chest will create 700-1,000 lbs of pressure.
  • 18-inches of soil covering a body exerts up to 1,800 to 3,000 lbs of pressure.
Here’s a recent fatality that occurred when workers were installing storm drains in Alamo, Texas.

OSHA has cited M&G Equipment Group Ltd., doing business as M Construction, with two alleged willful and six alleged serious violations following the death of an employee in March 2010 who was working in a trench installing a storm drainage system. “A company’s failure to protect its workers from cave-ins is simply unacceptable,” said Michael Rivera, OSHA’s area director in Corpus Christi, Texas. “If OSHA’s standards regarding proper trench sloping, shoring and shielding were followed, it is possible this tragedy could have been avoided.”

Serious citations were issued for failure to provide workers with safe egress when working in a trench, keep excavated soil a safe distance from a trench, use a properly designed trench shield, and ensure workers are trained on excavation hazards. A serious citation is issued when there is substantial probability that death or serious physical harm could result from a hazard about which the employer knew or should have known.

Proposed penalties total $53,550. OSHA standards mandate that all excavations 5 feet or deeper be protected against collapse. Detailed information on trenching and excavation hazards is available on OSHA’s Web site.

Field Work Essential in Trench and Structural Collapse Rescue

Tuesday, May 25, 2010

Extensive field exercises are considered necessary to develop the knowledge and skills necessary to conduct basic trench rescue operations. An overview of OSHA regulations for Excavations/Trenching should always include: shoring systems; hazard recognition and control methods; soil classification and mechanics; types of collapses; and patient care considerations.
