Where frequent cleaning is required, the guard may be constructed of mesh that prevents intrusion of body parts, but allows for hosing. Food production workplaces, that use conveyors in areas where hygiene or food safety is an integral part of the operation, use fixed mesh guarding of conveyor end rollers.
Separation is a simple and effective machinery and equipment risk control and may be achieved by distance, barrier or time. • Distance separation means a person cannot reach the hazard due to distance. • Barrier separation means an effective barrier or guard denies access and controls ejection of parts, products or waste. • Time separation means at the time of access, the machinery and/or equipment is disabled.
High integrity/fail-safe control. All safety control systems should be designed and built to prevent failure or, in the event of failure, de-activate the operation of the machinery and equipment. The extent to which a safety control system should tolerate faults is a function of risk (likelihood and consequence), and is described fully in AS4024.1501 Safety Related Parts of Control Systems, which explains the categories of control required as a function of increasing risk.
Equipments basically serve as tools, essential for the mechanical needs, to repair a machine. They are the most important items that have enabled the ancient humans to climb to the top of the food chain. They are things which help in the acquirement of any desired substance.
