17. Working with dangerous and irritating substances and
17.1. General provisions
17.1.1. This chapter should be read in conjunction with Chapter 7 which refers to
publications and codes containing essential information on the handling of dangerous

17.2. Work with unsaturated polyesters
17.2.1. Composite bonding material can contain unsaturated polyesters which may
cause skin irritation which can be difficult to control. Appropriate personal protective
clothing should be worn when using substances which contain unsaturated polyesters.
17.3. Work with adhesives
