Introduction

This leafl et describes in bullet-point form the specifi c hazards for personnel and the environment during preparation for thermal spraying and during thermal spraying itself; it also includes a structured breakdown of the necessary and mandatory safety measures. The most important spraying processes - powder-, wire-, highvelocity oxy-fuel fl ame (HVOF)-, arc- and plasma spraying - can largely be covered jointly; any differences between these processes are highlighted under subheadings. Specifi c hazards for cold spraying are described separately. Hazards with rarely used spraying processes are not covered here. The abbreviations used for rules and regulations are explained in Section 14, „References". The Appendix includes checklists that aim to make it easier to comply with environmental protection requirements, especially when planning a spraying facility or when changing to a different spraying process. The checklists can also be used to check the state of the art of an existing spraying device or an applied process, especially as environmental protection is regarded as a continuous process for reducing pollution of the environment.
