Tip Over, Fall, Collision, and Electrocution
As a machine operator or jobsite supervisor, you know how important it is to maintain a safe work environment. When working with mobile elevated work platforms (MEWPs), it's crucial to be aware of the risks that can arise. In this article, we'll explore the first four most common hazards associated with MEWPs and how to prevent them. We'll cover potential workplace hazards, including falls, tip-overs, electrocution, and collisions. This will help you keep your workers safe and prevent tragic accidents. So, let's dive in and learn more about the primary dangers of working with aerial lifts.
The first and most important safety rule while operating an aerial lift is to avoid hazardous situations.
We avoid hazardous situations by first identifying them in the safety section of the manufacturers’ model specific operator’s manual for the mobile elevating work platform to be operated and on safety decals located on the machine.
By carefully reviewing this information, you can become familiar with the specific hazards associated with your MEWP and develop strategies to prevent accidents before they occur. Remember, following safety guidelines is not just necessary, but also mandatory to ensure your own safety and the safety of those around you.
Proper training, common sense and planning can help you avoid hazards associated with aerial lift operation. Let’s discuss the four primary hazards associated with aerial lift operation one at a time.
Tip over hazards occur when the machine becomes unstable and falls over due to uneven ground, overload, or improper use. To prevent tip-over accidents, it's important to always operate the machine on flat and stable ground, avoid overloading the platform, and follow proper procedures for set-up and use.
Fall hazards happen when operators or workers fall from the platform due to improper use of safety gear or failure to follow proper safety.
Full body harness fall protection with personal fall arrest and fall restraint lanyards are required on boom lifts, but as safety protocols increase, most companies are calling for aerial lift operators to wear Personal Fall Protection Equipment all types of MEWP including scissor lifts and vertical mast lifts as well. Be sure to check with your employer to make certain you follow job site and governmental agency (OSHA, ANSI) specific requirements.
Collision hazards occur when the platform collides with an object, such as a wall or another vehicle. These include hazards to the aerial lift and surrounding areas as well as personnel collisions that result in injury.
Electrocution hazards are a major concern when operating MEWPs, as they can cause serious injuries and even fatalities. To prevent the risk of electrocution, it is important to understand the safety principles below.
Information regarding the required clearance from all power sources can be found in the operator’s manual and on safety decals attached to the machine.
Be especially aware of working near high voltage overhead power lines. These lines are most often not insulated. The operator or any part of the machine will not have to come in direct contact with a power line to be in extreme danger. High voltage electric current can jump up to 45 feet to seek a ground.
There are other hazards that can be found in the safety section of your MEWP operator’s manual including component damage hazards, explosion and fire hazards, damaged machine hazards, crushing hazards and bodily injury hazards so take the time to read, understand, and remember all hazards when moving and setting up your aerial work platform.
This article is designed to be an overview to help operators recognize and avoid some of the hazards associated with aerial lifts and is not intended to take the place of comprehensive operator training and hands-on familiarization of the specific machine to be operated.
It is important that aerial lift operators receive proper training that includes the requirement for a pre-operation inspection, comprehensive function tests as well as a workplace inspection prior to moving the machine to where work is needed. Re-training is required a minimum of every 3 years or if the operator has been involved in an incident or near miss, assigned to operate a machine with new or significantly different technology or has been observed operating the machine in an unsafe manner.
Remember, following proper safety measures when operating a MEWP can mean the difference between life and death. Take the time to fully understand and implement all safety protocols before getting on any aerial lift. Your safety and the safety of those around you should always be your top priority.
Alexander Equipment offers comprehensive aerial lift operator training that includes scissor lifts, boom lifts, and vertical mast lifts. OSHA mandates only trained and authorized personnel should be permitted to operate an aerial lift.
