Construction safety: introduction

Introduction to Health and Safety in Construction has quickly established itself, in its first two years, as the standard text for students taking the NEBOSH National Certificate in Construction Safety and Health. It is also of great value to those working in the construction industry at all levels, particularly construction site managers and foremen. As it has become a significant work of reference for managers with health and safety responsibilities, it is a matter of prime importance that it should be kept up to date, as far as is possible, with new legislation and recent developments. 

A walk-through safety, health, and environmental review must he completed after construction and before introduction of chemicals to ensure that repairs and additions have heen made as intended. 

The introduction to the code sets forth engineering requirements deemed necessary for the safe design and construction of piping systems. While safety is the basic consideration of the code, this factor alone will not necessarily govern final specifications for any pressure piping system. 

In terms of safety, two issues are regularly debated. First, the issue of nuclear waste and, second, concerns over potential terrorist attacks on nuclear power plants. The first objection may be overcome through the introduction of new types of power plants, such as the pebble-bed modular reactor.This type of reactor uses graphite balls flecked with tiny amounts of uranium, rather than conventional fuel rods. With the fuel encased in graphite and impermeable silicon carbide, the theory is that the waste should be relatively easy to dispose of.The terrorism fears are less easily addressed and may ultimately stall the construction of new plants in countries such as the U.S., where these worries are greatest.

This chapter provides a broad introduction to the state of the art in general causal inference methods with an eye toward safety analysis. In brief, the estimation roadmap begins with the construction of a formal structural causal model of the data that allows the definition of intervention-specific counterfactual outcomes and causal effects defined as functionals of the distributions of these counterfactuals. The establishment of an identifiability result allows the causal parameter to be recast as an esti-mand within a statistical model for the observed data, thus translating the causal question of interest into an exercise in statistical estimation and inference. This exercise is nontrivial in (typically nonparametric) statistical models that are large enough to contain the true data-generating distribution. 

In spite of this Fairbairn [51] complains about the number of weak bridges built as a result of the success of the Britannia and Conway bridges. There were defects not only in the safety factors used but the eroneous system of contractors tendering by weight, led not only to defects in the principle of construction, but the introduction of bad iron and, in many cases, equally bad workmanship. 

The Amarillo Workshop also saw the introduction of the nuclear materials safety boundary [4]. This construct sought to characterize the entire nuclear fuel cycle and define the components in which nuclear materials safety plays a role. The program boundary also identified the specific areas in which exchanges are taking place between DOE and Minatom in order to avoid duplication of existing efforts. 

In this period up to the TMI accident, three other facts influenced nuclear safety technology defence against non-natural external events the preparation of the Rasmussen report, WASH 1400 and the introduction of Quality Assurance (QA) in design, construction and operation of plants. 

Fortunately, an occasional leader has recognized the gravity of the situation and the need to take responsibility for changing this type of culture. The authors of this book not only found support from such individuals but also knew what to do with it. They had two very different experiences, as chronicled in the Introduction, but both authors made impressive changes in the cultures of their institutions. Each has been on the front line, and each has experience in implementing the techniques recommended in this volume. The lessons they learned from their experiences form the core around which this remarkable book is constructed. This book is not the outcome of a theoretical exercise. Its skeleton comes from the Harvard Executive Session on Medical Error and Patient Safety manifesto for leaders, but the knowledge and advice it offers come from practical, frontline experience. 

As this Toolbox Talk is an introduction to construction of electric power transmission and distribution lines and equipment, you may want to discuss your company safety and other rules that apply to these work situations. Include basic safe work practices and procedures and emergency procedures. Discuss possible scenarios where an employee could be exposed. The idea is to help employees recognize and know how to avoid hazards. Have personal protective equipment, electrical protective equipment, and special tools on hand to aid in your talk.
