Organizations like OSHA have made the construction industry a much safer environment for it’s workers. Still, workplace injury accidents occur.
The first step in building a structure is digging a trench to lay the foundation. This is done by excavation teams who are in charge of digging the right size trench. These excavation teams are usually trained and taught how to evaluate and dig trenches. They are also trained on precautionary and protective measures to reduce the risk of injury caused due to trench failures and collapses.
The Occupational Safety and Health Administration (OSHA), is a federal regulating body that has laid down certain rules, regulations and guidelines that construction workers should follow. In this article, we will discuss some of these safety measures that can reduce the risks of injury at construction sites.
Proper Training and Education
Trench excavators should have proper training and knowledge about soils, the types, weight and moisture content of different soil, water content and water tables, weather changes and their effects on soil, effects of vibrations caused by vehicles and effect of adjoining structures.
Inspection and Testing of Soil
Soil testing is an important stage in trench building that can determine the safety and stability of the soil that will be worked on. Soil is classified as rock, type ‘A’ that is clay or sandy clay, Type ‘B’ – gravel, Type ‘C’ – silt and sandy loam and farmers dirt. Soil tests like the Plasticity test, the Pocket Penetrometer test or the Shear Vane test can be conducted to measure the safety and stability of the soil that will be worked on.
Preventing Trench Cave-Ins and Collapses
Trench cave-ins and collapses can be prevented. OSHA has laid down certain guidelines for excavators to follow to avoid excavation related injuries. Workers should be well trained in the sloping and benching methods that can stabilize the otherwise weak walls of a trench. On sites where shoring and benching are not possible, they can use shielding methods where metal or timber shields or sheet piling can be done.
These methods can be used depending upon the height of the trench. According to OSHA, trenches that are more than four feet high require exits created within 25 feet of the workers working space. They also make it necessary for every trench site to have a copy of the maintenance inspection records, manufacturer’s details, technical information about the site and manuals for any machinery that is used at the work site.
Every construction company tries its best to ensure that proper safety standards and OSHA guidelines are followed at their work sites. Sometimes, in spite of taking precautionary measures and providing training to employers, trench collapses can lead to accidents causing injury to workers. Such accidents can cause severe injuries or even prove to be fatal.
These are the times when the construction company, along with OSHA, should attempt to evaluate the reason for trench failure. Inspection records, training given to workers, soil evaluations and other precautionary measures taken, like shoring or shielding methods implemented, should be re-evaluated to determine the causes of trench failure. Such quick actions can ensure better safety of the workers at construction sites.
