ensure understanding of latent defects / condition!
recognise when you need competent advice!
• Route map, tables & figures in 5 sections: – defines the terminology, design and management of areas
– explains the principles as part of the safety regime
– good use of diagrams
• Exclusion zones generally comprise of 4 areas: 1. plan area also remember to designate:
2. designed drop area “safe
3. predicted debris area working
4. buffer area spaces”
• Caution notes: not prescriptive, relies heavily on experience!
doesn’t define types of barriers & when needed
plus often poor at defining safe working spaces / routes
13. Safe working spaces & exclusion zones
