Design Work Regulations

The furnace combustion system contained two air/fuel-type burners firing at 14 x 106 Btu/h (4.1 MW), with air preheated to 500°F (260°C). The existing control system was designed to regulate firing rates to control the roof and bath temperature at desired set point. This system could meter the rate down below 5 x 106 Btu/h (1.5 MW) when the roof or bath temperature was attained. The EZ-Fire controls were incorporated into the existing furnace controls enabling the systems to work... 

Codes and standards provide a foundation for most of the design work. Generally, they summarize the knowledge and experience of hundreds of highly experienced engineers and other specialists. Not to use such experience would be foolish (and probably in violation of rules and regulations in many locations). 

This manual explains applicable laws and regulations, solid waste disposal alternatives, site selection considerations, design criteria, construction methods, and operating practices for sanitary landfills. Only disposal of non-hazardous solid waste at Army installations is addressed. The information described herein is applicable to feasibility studies as well as design work. 

Risk assessment is an essential part of complying with these Regulations and must be done (under the Management of Health and Safety at Work Regulations) to determine a safe system of work. The risk assessment needs to follow a hierarchy of controls to comply. This should start with the measures, both in design and procedures, that can be adopted... 

Apart from the above exceptions, the CDM Regulations apply to all design work carried out for construction purposes (including demolition and dismantling). 

So far as the electrical subcontractor is concerned, if the installation is designed to comply with the requirements of the Electricity at Work Regulations 1989 and in such a manner as to minimise the risks entailed in its construction and subsequent maintenance, it will be likely to be in compliance with the CDM Regulations. It is important, however, that the contractor cooperates fully with the other CDM duty holders and that he employs staff who are competent both in terms of the Electricity at Work... 

The Memorandum of Guidance to the Electricity at Work Regulations refers to the Standard and notes that installations that are designed in conformity with it are likely to achieve compliance with the Electricity at Work Regulations 1989. The HSE s electrical inspectors will generally use BS 7671 as a main guide when checking the safety of electrical distribution systems. 

Section 1 - General Requirements - is about the safety demands of Chapter 13 and some of the relevant legislation. It cites, however, only the Electricity at Work Regulations and the CDM Regulations. Attention is drawn to the responsibilities for safety of the designer, erector, maintainer and user.
