Blasting Best Practices Channeling the power of explosives is an impressive ability, and industries like mining and construction rely on controlled blasts for many purposes. They guide the force of blasts in a productive way through deliberate planning and secure practices.

Nearly 6.5 million people work at more than 250,000 construction sites across the country each day, according to Occupational Safety and Health Administration (OSHA). While most of these workers go home without serious injury, the fatal injury rate in the construction industry is, unfortunately, higher than the national average for all other industries. Construction workers are …

2nd Edition - Best Practices Guide for Close Proximity Blasting Operations – June 18, 2019 4 | P a g e E Edition 4 Purpose This Best Practices Guide for Close Proximity Blasting Operations has been developed utilizing the knowledge and experience of a wide variety of blasting and industry related professionals throughout North America.

should be hand-tool cleaned. Blast cleaning should be in accordance with SSPC-SP10-"Near White Blast Cleaning", a copy of which is included as 393.456 (26) thru (31). "Accessible surfaces" should be considered to mean those surfaces which would be accessible for blast cleaning in the erected structure, using conventional rigging.

BMP 1.0 Blasting & Surface Preparation 1 PURPOSE: The purpose of this BMP is to minimize the contribution of pollutants to the environment caused by blasting and surface preparation operations. Surface preparation includes such activities as buffing, dry abrasives blasting…

The bounds of the blast area were not adequately determined for this blast. In a coal mine blast, flyrock traveled 900 feet and landed beyond the permit boundary causing a fatal injury [MSHA, 1990a]. During a construction blasting operation near Marlboro, NY, flyrock was showered on passing motorists on Route 9 W about 180 feet from the blast pit.

Importance of Following Best Practices in Construction Among all economy, the construction industry is the largest and the important sector in the company that employs over 7% of the workforce. The national investment valued from the construction industry is $300 billion. A study by BERL shows that a 10% efficiency gain in this sector results ...

The purpose of this work group is to document common-sense best practices in the form of a white paper for use by Operators, Material Suppliers, Applicators and Contractors (corrosion control personnel, design engineers, project managers, purchasers, and construction engineers and managers).

Measuring water pressure pulses is a unique challenge when blasting underwater. Detecht consultants have been involved in several pier demolition and underwater rock blasting projects. They are experienced with the special challenges that come with marine monitoring and have published on best practices for underwater instrumentation.

Blasting contractors should lay out the drill pattern based on a surveyed profile of the face. At a minimum, a profile survey should be done after drilling and before loading so that the proper explosive load can be determined for each blast hole based on the survey and drill log. A best practice would be to profile both before and after drilling.

The research effort led to the development of five distinct solution elements: 1) business case process, 2) execution plan differences, 3) critical success factors, 4) standardization strategy, and 5) modularization maximization enablers. For successful modularization to occur the message is clear: Substantial owner involvement must occur early.

Blasting is often the most cost-effective way to get large amounts of substrate cleaned quickly. Of course, to ensure blasting remains cost-effective, you should follow a few best practices. 1. Measure PSI at the Nozzle. Air pressure should be at least 100 PSI at the nozzle. Maintaining 110 PSI or even higher is better.
