Planning safe working at height using mobile elevating work platforms

When it comes to working at height safely, mobile elevating work platforms, also called EWPs and MEWPs, can be a real game-changer. But here’s the thing – you can’t just jump in and start using one without proper EWP training and planning, and working at height training. Let’s talk about how to set yourself up for success when using MEWPs.

Firstly, you’ve got to identify the hazards and assess the risks. Take a good look around and think about what could go wrong, such as falls from the platform, the MEWP tipping over, hitting overhead obstacles, or crushing someone against a fixed structure. You’ve also got to consider falling objects, weather conditions, ground stability, and how close you are to power lines. Once you’ve spotted the hazards, figure out how likely they are to happen and how bad it could be if they did. Then, come up with ways to eliminate, isolate, or minimize those risks.

Choosing the right MEWP is not one-size-fits-all. You need to think about the working height and outreach you need, how much weight it can safely carry, and what kind of ground you’ll be working on. If you’re working indoors, an electric MEWP (often called a slab scissor lift) might be your best bet, but for outdoor work, you might need a diesel-powered boom lift or rough-terrain scissor lift. Always check the manufacturer’s specs to make sure you’re making the right choice.

Before you even bring the MEWP on-site, you need to do a thorough site assessment. Figure out how you’re going to get the MEWP to where it needs to be, and make sure the ground can support its weight. Look out for slopes, uneven ground, overhead power lines, and underground services, and don’t forget to plan how you’re going to cordon off the work area.

Weather can be a real wildcard, so keep an eye on the forecast. Strong winds are a no-go, and you definitely don’t want to be up there during a thunderstorm. Rain, snow, or ice can make things slippery and affect visibility, so take that into account too.

If you’re working near vehicles or other mobile plant, you’ll need a solid traffic management plan. Use barriers and signs to keep the work area separate, and consider using spotters or traffic controllers if needed. Make sure the MEWP is always visible to drivers and coordinate its movements with other site activities.

Now, let’s talk about the operators. They need to be properly trained and competent. In New Zealand, we’ve got specific NZQA unit standards for this. Unit standards are optional, but recommended; you can do training that meets or exceeds the unit standards, and then you do a refresher every three years. Operators need to understand the MEWP they’re using, know the emergency procedures, and be physically and mentally fit for the job.

Even though MEWPs have guardrails, you still need additional fall protection. Operators should wear a full body harness with a short lanyard, especially on boom-type MEWPs. And always have a rescue plan in place, just in case.

Setting up exclusion zones around the MEWP is important too. Barricade off the full reach of the MEWP plus a bit extra, and use cones, barriers, and warning signs to keep people out.

Emergency planning is crucial. Make sure everyone knows how to call for help, how to lower the MEWP in an emergency, and how to rescue someone who’s fallen. Practice these procedures regularly.

Before each use, do a thorough inspection of the MEWP. Check all the safety devices and controls, look at the structural elements, hydraulics, and electrical systems, and test the emergency lowering system. Keep a logbook of these inspections.

Develop detailed procedures for working safely on the MEWP. This includes how to get on and off safely, maintaining three points of contact when moving, keeping the gate closed, not overreaching or climbing on the guardrails, and avoiding overloading.

Supervision is key. Keep an eye on things, make sure everyone’s following the procedures, and don’t be afraid to stop work if something doesn’t look right.

Lastly, keep all your documentation on site. This includes your hazard assessments, control plans, the MEWP manual, inspection records, operator certificates, and emergency procedures.

Remember, planning is everything when it comes to using MEWPs safely. By taking the time to assess the risks, choose the right equipment, train your operators, and put solid control measures in place, you can manage the risks effectively. Always check the current New Zealand regulations and best practice guidelines when you’re planning your MEWP operations. Stay safe out there!
