Effective machinery and equipment risk controls reflect some or all of the following characteristics: • the hazard is controlled at its source • contact or access to the hazard is prevented • sturdy construction (correct materials with few points of potential failure) • fail-safe (failure of the control system to be effective will result in machinery shut-down) • tamper-proof design (as difficult as possible to bypass) • presents minimum impediment to machinery and equipment operator • easy to inspect and maintain • does not introduce further hazards through the risk control action.
The first step in selecting suitable and effective controls for non-mechanical hazards is to understand the nature of emissions that can be released by machinery and equipment in the workplace, where those emissions collect and the way they may cause harm.
Working at height. Providing people with a suitable work platform for the task being undertaken reduces the risk of injury from falling from machinery and equipment. Often safe access equipment, made available during installation of machinery and/or equipment, is removed after commissioning.
Administrative controls use systems of work to reduce risk by providing a framework of expected behaviours. Examples are rotation of staff to reduce exposure to a hazard, or a documented safe system of work, such as lockout tagout. These types of controls rely on extensive instruction, information, training and supervision.
