Plan, prepare, prevent and protect
Excavated trenches pose a serious risk to the health and safety of all your workers. So if you're in charge of a worksite, always plan ahead before any excavation work commences. Don't let an ordinary day end in disaster. Plan, prepare, prevent and protect. Make sure you understand the risks and use the controls.

Safe work method statements (SWMS)
Safe work method statements are an important part of preparing for any high risk construction work (HRCW). Hear from our inspector, Brian Chamberlain on why these documents are so vital.

Hazards
- Hazard 1Lifting pushing pulling and handling materials
- Arrange for bulky materials to be delivered to the final work location or use mechanical load shifting devices (eg cranes, material hoists, forklifts, hand trucks) to move materials around site.
- If moving bins around site, consider using powered bin lifters.
- Provide lifting points or handles for heavy or awkward loads.
- Order materials in smaller sizes (eg cement bags of 20kg instead of 40kg).
- Provide appropriate personal protective equipment (eg hard hats, gloves that absorb impact energy, protection from sharp edges that is puncture resistant, hearing protection, respiratory protection, suitable eyewear).
- Ensure employees wear appropriate personal protective clothing (eg long pants, boots).
- Cover sharp edges of metal sheeting and strips.
- 8 per cent of the injuries were to a persons shoulder.
- 17 per cent of the injuries were to a persons back.
- 13 per cent of the injuries were to a persons hand/fingers.
- 8 per cent of the injuries were to a persons leg.
- Hazard 2Noise
- Ensure employees are not exposed to noise that exceeds the exposure standard.
- Arrange for a noise assessment if employees are exposed to excessive noise (eg workers have to raise their voices to communicate over a distance of one metre) and there is uncertainty as to whether employees exposure may have exceeded the noise exposure standard.
- Eliminate or minimise the source of noise (eg enclose or isolate noisy machinery, reduce vibration, use barriers to absorb and screens to block the direct path of sound, use silencers on air exhausts, exhaust pneumatics out of the area, buy the quietest tools / machinery available).
- Place warning signs in areas of excessive and continual noise (eg where employees exposure is likely to exceed the exposure standard).
- Warn other workers nearby that you will be undertaking noisy work and advise them to move away or wear hearing protection.
- Provide hearing equipment, ensure it is worn at all times, and provide employees with audiometric testing. Employers should provide a choice of different types of hearing protection appropriate to the noise level in the workplace.
- Hazard 3Slips trips and falls
- Provide appropriate height access equipment and use the highest level of falls protection (eg guard-railing, scaffolds, physical barriers or elevated work platforms) as is reasonably practicable.
- Ensure all working areas and access ways are clean, level, well-lit and in good condition.
- Remove unwanted material and construction waste regularly from site so it does not accumulate.
- Ensure construction materials, power leads, tools and equipment are positioned and secured to avoid creating tripping hazards.
- Fit rebar ends with protective caps.
- Ensure employees wear appropriate safety boots (eg that fit well and are in good repair).
- 8 per cent of the injuries were to a persons shoulder.
- 17 per cent of the injuries were to a persons back.
- 13 per cent of the injuries were to a persons hand/fingers.
- 8 per cent of the injuries were to a persons arm.
- 10 per cent of the injuries were to a persons knee.
- 8 per cent of the injuries were to a persons leg.
- Hazard 4Using hand tools
- Provide appropriate mechanical aids and equipment (eg power tools that are lightweight, low vibration, noise restricted and fitted with clutches and safety guards, ergonomically designed) and ensure they are used properly and maintained in accordance with manufacturer specifications. Minimise the use of manual tools (eg knee kicker).
- Ensure exposed nails are knocked in.
- Train employees, especially young workers, in the selection and use of hand tools and how to safely use them (eg avoid working in front of face and always work away from the body).
- Ensure employees are not exposed to repetitive work for long periods (eg by using job rotation, work variation) or work that requires a significant amount of high force.
- Provide appropriate personal protective equipment (eg hard hats, gloves that absorb impact energy, protection from sharp edges that is puncture resistant, hearing protection, respiratory protection, suitable eyewear).
- Ensure employees wear appropriate personal protective clothing (eg long pants, boots).
- 13 per cent of the injuries were to a persons hand/fingers.
- 8 per cent of the injuries were to a persons arm.
- Hazard 5Working at ground or floor level
- Provide appropriate mechanical aids and equipment (eg tables, benches or stands that bring work to waist height, tools with extension handles, carpet stretchers) and ensure they are used properly and maintained in accordance with manufacturer specifications.
- Ensure employees are not exposed to repetitive work for long periods (eg by using job rotation, work variation).
- 10 per cent of the injuries were to a persons knee.
- 8 per cent of the injuries were to a persons leg.
