A guard can perform several functions including: • denying bodily access • containing ejected parts, tools, off-cuts or swath • preventing emissions escaping • forming part of a safe working platform. Guarding is commonly used with machinery and equipment to prevent access to: • rotating end drums of belt conveyors • moving augers of auger conveyors • rotating shafts • moving parts that do not require regular adjustment • machine transmissions, such as pulley and belt drives, chain drives, exposed drive gears • any dangerous moving parts, machinery and equipment.
When using fall-arrest systems, specialist assistance may be necessary to select appropriate equipment, provide effective training in use and inspection, and develop an emergency retrieval plan to recover a person suspended in a fall-arrest harness. People suspended by a fall-arrest harness for short periods of time may suffer serious health effects, or may have incurred injury during the fall prior to the fall-arrest device deploying.
Emergency retrieval plans should allow for immediate local response in safely retrieving people to avoid fatalities.
A stable work platform, suited to the nature of the work that allows for good posture relative to the work performed, sure footing, safe environment and fall prevention (if a fall may occur), is a basic requirement. For example, cooling towers on building roofs may have poor access, yet must be attended by a service person at predictable times for water treatment, chemical dosing or monitoring of automated dosing equipment.
