Sample
The South African Institute of Materials Handling (SAIMH) is a Non-Profit organisation set up with an objective to encourage the transfer of knowledge associated within the fields of Bulk Materials Handling (conveyors, stacker, reclaimers, tipplers, train loading systems, etc.) through a combination of seminars and networking sessions. The SAIMH is made up of professional engineers, each practising their trade in a variety of organisations who volunteer their time to execute the SAIMH’s objective. The main aim is thus to promote the advancement of the art, science, theory and practice of the Bulk Materials Handling principles and techniques.

Rescue at Height Any safety-related incidents when working at height often necessitate self-rescue as the front-line or most rapid-response tactic. In this regard, MSA Africa is introducing its Latchways Personal Rescue Device (PRD), an integrated harness system. This lightweight, unobtrusive rescue device is contained in a small backpack attached to a full-body harness. It has been designed to be used in conjunction with a fall protection system or anchor point. The components of the PRD fit neatly into the backpack, allowing workers to carry out their daily tasks unhindered. The backpack becomes part of the daily Personal Protective
Equipment (PPE) required for those working at height. In the event of a fall, the PRD suspends the worker, who is then lowered to the ground gently in a controlled descent. The device features a 20m spool of Aramid rope, released at a controlled rate via an integral braking mechanism. Unlike competitor rescue kits, the MSA Latchways PRD requires no specialist training, as it is simply worn in conjunction with a standard full-body harness, and is activated by simply pulling the release cord. Its user-friendliness is enhanced by the fact that pre-use checks are minimal.
