Indoor air quality and human health are of continuously growing importance. Indoor air quality may be affected by many factors excluding, but not limited to, more loosely sealed buildings, the use of air purifiers and other pollutant sources (for example, room air fresheners), the use of various chemicals for pesticide management and cleaning, and finally, the use of synthetic building materials and furnishings. In recent years, people have become more aware of potential health and comfort problems that may be associated with poor indoor air quality. It is partly due to the move to more tightly sealed buildings, the implementation of energy conservation programs, and the growing use of laser printers, photocopiers, and other sources of indoor air contamination. Greater general awareness of environmental issues may also play a part. Most IAQ complaints from building occupants are related to a respiratory headache, irritation, odours, or fatigue. These concerns may be associated with chemical vapours, dust generated in the work environment, contaminants associated with fungal growth (mould), materials infiltrating from outside sources (such as pollen or engine exhaust), or other factors such as elevated carbon dioxide levels. This handbook aims to turn the attention to these subjects and to promote methods and technologies to reduce poor indoor air quality and to distribute outdoor air throughout the building, remove contaminants and odours, and control the indoor temperature and humidity. The information in this guide will help to maintain good indoor air quality in a building, prevent indoor air quality problems, and correct issues that may arise. It will also help to understand the indoor air quality requirements. The structure of this text allows for flexibility in course content and design. It may be used equally well either as a textbook for students or a handbook for environmental consultants, mechanical engineers, building occupants, labour unions and suppliers. Furthermore, this text may be useful data for either the undergraduate or the graduate level.

This book is a guidebook for the health and safety of workers and will help to prevent workplace accidents. It covers five sections of work environments with dangerous hazards and high health risk. Every chapter has been expanded to include knowledge and skills to promote and maintain safety and health in a work environment, and these chapters analyse the duties of employers and employees. Risk factors in relation to safety in specific workplaces and issues concerning contamination prevention and control are investigated, and hazards and risks when workers are using equipment or handling hazardous materials and waste are examined. This book includes multiple points of interest for businesses and industries with potentially harmful work environments: Welding works Municipalitys waste collection Working in modern workshops Working on sea vessels Working on offshore wind farms Hazards in welding environments are analyzed and steps to minimizing health and safety risks in welding operations are put forward. Concerning municipality waste collection, this book gives an overview of waste, waste management processes, and research concerning health hazards, illnesses and injuries. As machine tools pose multiple hazards, this book studies requirements for a safe workshop, along with the equipment requirements and their possible hazards, inspection and service procedures. Accidents at sea are still a common occurrence, but significant progress has been made in recent decades and all involved stakeholders enact accident avoidance and mitigation measures in accordance with current norms and legislation. This additional effort was made to present the duties and responsibilities from seafarers up to ship owner and the best practices proposed to conduct successful sea operations without damage or loss. Finally, this guidance presents risks and hazards on health, safety and environmental parameters that inform about the procedures and standards that are applied in the offshore wind industry.
