Hazards of Operating Electric Forklifts in Narrow Aisles

The great benefit of having a narrow aisle storage system is that it grants more storage rooms for goods and materials to be stacked.
But it is not without a disadvantage – it requires an electric forklift such as a reach truck or order picker to be driven in much tighter aisle width.

And there are hazards associated with operating an electric forklift in narrow aisles. You would not want to get into an accident because safety has to come first so it would be necessary to know more about these risks.

Here are the major and minor hazards of forklift operation in narrow aisles:

Collision Risk

Operating electric forklifts in narrow aisles significantly increases the likelihood of collisions. The tight spaces leave little room for error, making it easier for forklifts to bump into shelving units, collide with other forklifts coming from the opposite direction, or even accidentally strike pedestrians working in the area. These risks are exacerbated by limited visibility around corners and at intersections within the aisles. To mitigate these risks, implementing comprehensive training programs that emphasize spatial awareness and installing additional safety equipment like mirrors at corners can help reduce the incidence of collisions.

Load Stability

The challenge of maintaining load stability becomes more pronounced in confined areas. Narrow aisles restrict the forklift's maneuverability, making it harder to navigate turns and place loads safely without tipping. The risk is higher when lifting loads to greater heights, where even slight miscalculations can lead to instability and potential accidents. Employing forklifts equipped with stability-enhancing features and ensuring operators are trained in load management techniques specific to narrow aisles are critical steps in addressing these challenges.

Battery Hazards

Electric forklifts rely on large batteries that pose unique risks, including electrical hazards and the potential for chemical spills. In the confined spaces of narrow aisles, the consequences of battery issues, such as a short circuit or a leak, can be more severe, affecting not only the operator but also nearby workers and merchandise. Regular battery maintenance and inspections are essential to prevent such incidents. Additionally, ensuring that forklift operators and maintenance personnel are trained in handling battery-related emergencies can reduce the risk of accidents.

Ergonomic Challenges

The operation of forklifts in restricted spaces can lead to increased physical strain on operators. The need for constant vigilance, precise control, and frequent maneuvering in tight spaces can contribute to fatigue, stress, and musculoskeletal problems. To combat these ergonomic challenges, it's important to design work shifts that allow for regular breaks, provide seats with adequate support and adjustability, and offer training on proper posture and techniques for minimizing strain. Additionally, considering ergonomic design in the selection of forklifts can help reduce operator fatigue and the associated risks of accidents.

Untrained Forklift Operators Pose a Serious Risk

One cannot drive an electric forklift if he used to operate one type of machine, let’s say an LPG-powered truck. Specific training for electric forklifts must be given to the worker that addresses the specifics of its unique operation.

If the address is not familiar with an electric forklift, he needs to be certified first on that. The training can be completed in less than a day. You can contact the nearest training provider in your area for the arrangement of training.

Maneuvering of the truck Also Poses Risk

It is true whether you have a standard-size or narrower aisle. Maneuvering is a risky undertaking for operators to do. Since a forklift is not being driven just like a vehicle does, the back end of the machine veers wide during a turn, and anyone nearby could be hit by the truck during maneuvering.

Or with just a momentary loss of focus of the operator, he could knock the shelves and bring down the entire racking system. I know you’ve seen the video already. If not yet, see the video here.

Speedy Driving in the Narrow Aisle is Dangerous

Just like speeding on the highway with your car, speed either kills or causes damage. The same thing could happen in a forklift when driven in a narrow aisle. Although you may say that it is slow-moving with the weight and momentum as it moves, it could cause serious harm to other people if they get run over or damage other vehicles when plowing into those things.

Pay attention to the surroundings, and never ever drive the truck at high speed. The narrow aisle should be given due respect.

The Load Being Carried Also Poses a Serious Hazard

First, it creates a blind spot for the operator. When working in proximity to pedestrians, it is far more helpful to use a spotter to guide through the way and caution incoming foot traffic of the passing-by forklift.

Forklift operators can manage blind spots if they cannot be avoided, slow down or drive in reverse for better visibility, or always have a buddy to help you through the narrow aisles.

The other thing that could help you in blind spots is by installing safety mirrors in the workplace. Safety mirrors are a good addition to every workplace as it add more visibility in key locations. You may recommend this to your supervisor if you think you’re having problems with blind spots.

The second reason is that if the load is off-balanced when being lifted or carried, it can become unstable. Such a situation is worse when making a turn or when the load is raised to the highest position.

The arrangement of the pallet, weight and size of the load affects the stability. To know more about the capacity the truck can carry, see its data plate.

The Pedestrian Themselves Pose Hazard

It is no surprise that people and other workers can post hazards in such areas. Machines and people don’t mix, it is always the machine that wins. But pedestrian traffic is part of everyday life in the warehouse. It is impossible not to get near the forklift.

Good thing, technology has something to offer to reduce hazards and the likelihood of accidents. Nowadays, sensors can be fitted to the forklift so that it activates the traffic lights installed in the area, cautioning pedestrians that the truck is approaching in their direction.

Debris and Garbage (Poor Housekeeping) Also Poses a Danger

Well, we all know we need to keep the workplace neat and clean at all times. It is important to conduct regular housekeeping so that tools, chemicals, and garbage don’t litter in the workplace.

One such example is that poor housekeeping posts hazard when oil flows in the narrow aisle floor surface, when the truck passes, the tire may lose grip, and you know what will happen.

Poor housekeeping is an unsafe condition that must be addressed immediately.

Other Dangers of Operating Electric Forklifts in Narrow Aisles

Operating electric forklifts in narrow aisles presents several hazards that can cause accidents, injuries, and damage to equipment and inventory. The following are some of the hazards associated with operating electric forklifts in narrow aisles:

• Tip-over risks due to narrow clearance: The narrow width of aisles can increase the risk of electric forklifts tipping over. This can be caused by uneven floors, sudden turns, or overloading the forklifts beyond their capacity.
  
  
• Collision risks with other forklifts or fixed structures: The narrow width of the aisles can also increase the risk of collisions with other forklifts, pallet racks, and other fixed structures. This can cause damage to equipment and inventory and increase the risk of injury to operators.
  
  
• Reduced visibility due to narrow aisle width: Narrow aisles can reduce visibility for operators, making it difficult to see other forklifts, obstacles, and pedestrians. This can increase the risk of accidents and injuries.
  
  
• Overhead obstructions such as low-hanging lights, pipes or shelves: Narrow aisles can also create a risk of overhead obstructions that can cause accidents and injuries to operators. This can be caused by low-hanging lights, pipes, or shelves that are not properly secured.
  
  
• Electric shocks due to close proximity to power sources: Narrow aisles can also increase the risk of electric shocks for forklift operators. This is because the forklifts are often operating in close proximity to power sources such as electrical panels and outlets.

Operating electric forklifts in narrow aisles requires careful planning and implementation of safety measures to reduce the risks of accidents, injuries, and damage to equipment and inventory. Businesses should ensure that operators are properly trained and equipped with the tools and equipment they need to operate safely in narrow aisles.

Hazards Analysis and Risk Assessment Can Be Done to Ensure Safety

Hazard analysis and risk assessment are useful tools for eliminating hazards in the workplace. These are straightforward methods that you or the safety officer can use to measure risks or hazards before starting work.

The purpose of doing this is to identify dangerous conditions that could cause harm, evaluate the risks associated with those hazards, and determine if they can be reduced or eliminated.

If you think a risk analysis would be beneficial in your workplace, you can request it from the safety officer or have a professional conduct it for you.

Conduct Toolbox Talk to Forklift Operators Regularly

Another smart strategy to lower the risk and hazards of operating an electric forklift in narrow aisles and tight spaces is to conduct a toolbox talk.

We used to hold meetings in the morning before every shift. Each week, we had a scheduled list of topics, ranging from basic and simple issues to the more serious ones.

We conduct toolbox talks as if we're casually chatting with the workers. We avoid using technical jargon that might confuse them. A toolbox talk is effective for conveying information to the workers, making them more aware of safety.

If I were in your position, I would recommend implementing this practice in your workplace if it isn't already in place. It only takes about 5-10 minutes and has a significant benefit: reducing accidents.
