Note: When considering the suitability of distance guarding, consider the safe access requirements of maintenance people who gain access by ladder, scaffold or elevated work platform.
A tool generally is any physical item that can be used to achieve a goal, especially if the item is not consumed in the process. Informally, it also describes a procedure or process with a specific purpose.
Lower order machinery and equipment risk controls, such as personal protective equipment (PPE), can prevent injuries, but are generally not as effective as higher order controls, as they rely more on worker behaviour, maintenance programs and supervision.
Where access is not anticipated, a fixed guard can be permanently applied by a bonding agent, welding, or secured with one-way screws. If access is generally not required, a permanently fixed barrier is the preferred option.
