Plate 18 Structure of the NF-kB p50 homodimer bound to a 10 base pair kB- responsive DNA site. The structure of the DNA-binding p50 subunit of NF-kB complexed with DNA is an example how /3-sheets make specific contacts with the DNA. The p50 NF-kB subunit dimerizes. Both halves are folded as a /3-sandwich. The dimer wraps around the major groove of the unfolded DNA double helix, and the /3-sheets make the specific contacts. The N-termlnal part of NF-kB p50 is similar to the core domain of the tumour suppressor, p53 (see Chapter 15). (The ribbon structure was constructed with permission of the authors and Nature from data in ref. 23 of Chapter 9 see also ref. 24 of Chapter 9.)... 

When individuals come in contact with contaminated soil during ranching, dust storms, or proximity to construction sites or archaeo-logic excavations, arthroconidia are inhaled into the respiratory tree, where they transform into spherules, which reproduce by cleavage of the cytoplasm to produce endospores. The endospores are released when the spherules reach maturity. Similar to histoplasmosis, an acute inflammatory response in the tissue leads to infiltration of mononuclear cells, ultimately resulting in granuloma formation. ... 

Density and Moisture Tester (MC-l). A 50 mCi mixture of Americium-241 and Beryllium is located within the base of the MC-l (about 200 times more than is used in the M43A1 Chemical Agent Detector). Neutron emission occurs when an alpha particle emitter such as Americium-241 is mixed with Beryllium (Be) powder in a tightly compressed pellet. The MC-l also has a 10 mCi Cesium-137 source located in a probe tip used to determine the density of the soil at a construction site. This source is classified as a special form source and is double-encapsulated in stainless steel. TACOM is the NRC license holder for the MC-l and is responsible for item management. 

Within Saudi Arabia, there also is a strained relationship with Western oil workers and their families. While Saudi people work for Saudi Aramco, the state-run oil monopoly. Westerners are responsible for the bulk of the managerial and design work. "As one energy expert affiliated with another state oil firm in the developing world put it Think of the expatriates as the architects at a construction site. They do not do all the work by any stretch of the imagination, but should they leave, the remaining construction workers lack the vision and expertise to care [sic] the project to fruition," explained Zeihan (2004). 

But these different constructions of safety are also readily able to demonstrate that there are distinct and different understandings of safety to be found within the site environment. Indeed both can be enacted by the workforce at the same time - such is the nature of our social world and therefore the realities of our construction sites. Safety is either its own entity, separate from the individual in both action and responsibility, or it becomes an inherent part of social interaction, bound up with people and practice in terms of their own actions and responsibilities. And people often draw on either or both of these two different constructs within their interactions, even shifting between them within a single conversation safety becomes an entity in some contexts, yet inherent within practice in others. 

These contrasting constructions of safety serve to illustrate the complexities of safety itself, and also indicate the very personal nature of the associations and interpretations that ultimately inform interactions and responses to safety within the construction site context. Although it could be suggested that safety management... 

The different levels of management found within the construction site context, and the different ways in which they implement and construct safety on sites create what can be termed a hierarchy of safety. Through the relationships that develop between the violators of the safety rules and those tasked with their enforcement at various levels of management, further considerations of how the responsibility for, and ownership of, safety works in practice can be explored. 

One measure of competition is response time or speed of response. Blackburn [6] and Stalk [86] describe firms that compete on delivery speed. One example is Atlas Door, an industrial door company that coordinated its supply chain to offer custom door delivery (for reactors or furnaces) within two weeks, when the industry standard was over four months. Atlas performed at this level by coordinating order quotation and scheduling production, excess capacity, and tools, synchronizing all components so that a complete kit was delivered to the construction site. Atlas s market share increased rapidly to 80% of the industry volume within five years, with a 15% price premium. 

Probably, the first instances of wider practical commercial use of fuel cell power plants will take place in connection with heavier transport equipment used within cities and near cities—buses and tmcks supplying merchandise to the local trade and materials to construction sites. This heavy transport equipment is responsible for large part of air pollution in big eities. They can be readily equipped with compressed hydrogen tanks. Creating an infrastrueture for hydrogen distribution and refueling is easier within a city than all over the eountry. 

The health and safety regulations make the main contractor responsible for the health, safety and welfare of all workers on the construction site. The main contractor must put in place a health and safety policy for each construction site and provide guardrails, working platforms, lighting, toilets, hand-washing facilities, first aid and site accommodation. There is also a duty to wear head protection on-site, including electricians. 

The contractor - the main contractor takes on the responsibility of the whole project for the client. The main contractor may take on a subcontractor to carry out some part of the whole project. On a large construction site the electrical contractor is usually the subcontractor. 

The Health and Safety Regulations make reference to workers having a duty of care for the health and safety of themselves and others in the workplace. The Electricity at Work Regulations identify one responsible person on-site as the duty holder . This recognizes the responsibility of an electrician to take on the control of electrical safety for the whole construction site. 

CDM are the initial letters of the Construction (Design and Management) Regulations 1994, which place responsibilities for safety on construction sites on everyone involved, from the designer and the client to principal and sub-contractors. 

Where sound levels exceed the PNEs, you must also implement a hearing conservation program. An effective program monitors employee exposure, administers annual audiograms, trains workers, and maintains proper recordkeeping. You should keep records on the noise created by different machines and operations at your construction site. Measurements should be taken with a sound level meter, at slow response, measured on the A-scale. 

The creating employer is the employer whose activities actually create a hazardous condition, while the correcting employer is the employer that has the responsibility for correcting the hazardous condition. An exposing employer is any employer whose workers are exposed to the hazardous condition. Depending upon the situation, any employer at a construction site could fall into one or more of these classifications and could be issued a citation by OSHA. 

Part 1 - The RRFSO applies to all non-domestic premises including construction sites other than those listed in Article 6. The main duty holder is the responsible person in relation to the premises, defined in Article 3. The duties on the responsible person are extended to any person who has, to any extent, control of the premises to the extent of their control (Article 5). 

The HSC believe that single-point overall responsibility for the management of health and safety on the construction site is crucial. We therefore propose to... 

The Fire Safety Order 2005 covers all premises which should include construction sites. At the time of going to press there was some confusion about whether the fire sections of the CHSW would be retained in the revised CDM Regulations. It is assumed that they will be reworked to avoid some overlapping of responsibilities between the HSE and Local Fire and Rescue Authorities. The sections cover the following issues. 

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. 

Nuclear installations, construction sites and ships xmder construction and repair where enforcement is the responsibility of the HSE. 

Section 4 applies to persons in charge of premises where people work and who are not their employees. They must ensure that the premises, any plant (including the fixed electrical installation) and the means of ingress and egress are safely maintained. An obvious example of the application of this duty is a construction site where the main contractor is the person in charge and in control of the site and who is responsible, therefore, for ensuring that the site is safe for the subcontractors labour forces.
