Support Continued from page 61 one hand should be done with the utmost care as this creates a very dangerous situation for the climber. Rather make use of a tool belt or hoist the tools and equipment to the work height with a rope. You must at all time during ascending or descending towers use your safety harness and make use of both the safety devices. • Start climbing the access ladder and hook the hip safety catch to the tower. • Climb higher as far as this safety hook allows. • Take the top (shoulder) safety hook and attach it to the tower as high above you as you can reach. • Repeat the process as you are ascending until you reach your workstation. • Attach the top safety catch above your head and the hip safety catch to the structure. • While you are moving one of the two safety catches must be attached to the tower. • When stationary and working both safety catches must be attached to the tower. When descending, the process is reversed: • Climb down so that you can still reach the top safety catch and hook the hip safety catch to the tower. • Unhook the top safety catch and hook it next to the hip safety catch. • Unhook the hip safety catch and repeat the process until on the ground. Reporting of incidents Incidents or near-miss incidents should be reported at all times. The reasons for this are: • It is a legal requirement that the employer investigate incidents and near miss incidents. These investigations are not to blame you or to assign blame but to establish what went wrong so that it can be prevented in future. • Equipment needs to be inspected more thoroughly and cleared as usable before it is used again. (If not properly inspected it may result in the equipment failing the next time.) • Your injuries might on look superficial to you but might progress into more serious injuries. If not reported the Workmen’s Compensation Commissioner might not cover these injuries. • You need to report these incidents as soon as possible after they happen. In the event of an incident Incidents can happen to all of us, and you cannot say it will not happen to me. What should you do? • Stay calm. • Assess your situation. (Hanging from a safety line/hurt/ bleeding) • If you’re hanging from the tower, try to get back on the tower. • Back on the tower, try to hook in your second safety line and stay stationary for a while to calm your nerves. • Decide what to do next, like continuing or descending. Be careful whatever you do. • If your situation is of such a nature that you are severely injured or cannot get back on the tower, call for help and stay calm till help arrives. (Company procedures can be established for this and to engage instances where the person might not be able to call for help.) Zane, this is in fact quite a complex issue. A full safety file should be put in place with risk assessments which have been conducted prior to commencement of work, ladder inspection reports correct scaffold usage, erection and inspection, to name but a few aspects. I hope that this assists you and helps to create some awareness. Thank you for all your questions.
