What is the weight limit for lifting boxes per employee?

In Belgium, there is no legally mandated absolute weight limit for lifting boxes in the workplace. However, the Codex on Well-Being at Work requires employers to conduct a risk assessment and keep the physical strain on employees as low as possible. As a general guideline, occupational health physicians recommend a maximum weight of 25 kg for men and 15 kg for women for occasional lifting under optimal conditions. In practice, however, the safe limits for handling boxes in the workplace are often lower, depending on posture, frequency, and the specific work situation. This article answers the most frequently asked questions about weight limits for lifting boxes, the relevant legislation, and the practical solutions available.

What is the maximum weight an employee is allowed to lift under the law?

Belgian law does not impose a fixed maximum weight limit for lifting boxes. However, the Codex on Workplace Well-Being requires employers to assess and control manual handling. As a practical guideline, the limits are 25 kg for men and 15 kg for women for occasional lifting under ideal conditions, such as a straight posture and a favorable lifting zone.

Specifically, the law requires a risk analysis based on the NIOSH method or a comparable ergonomic assessment tool. This analysis takes into account the weight of the load, the distance from the body, the lifting angle, the lifting frequency, and the duration of the activity. Based on these factors, the legally acceptable lifting weight per employee may be significantly lower than the general guideline.

Special attention is given to vulnerable groups: stricter standards apply to pregnant employees, young people, and employees with health issues. Employers are legally required to take appropriate measures for them, such as lowering the maximum weight limit or using lifting aids.

How do lifting techniques and work posture affect the safe limit?

Lifting technique and body posture have a major impact on the maximum safe lifting weight. A load lifted close to the body and at waist height places significantly less strain on the spine than the same load lifted far from the body or from a bent-over position. Poor technique can reduce the safe limit by 30 to 60 percent.

The Impact of Lifting Technique

When lifting ergonomically, the worker bends the knees, keeps the back straight, and holds the load as close to the body as possible. This distributes the weight across the leg muscles rather than the back muscles, which significantly reduces the strain on the lumbar vertebrae. A 15-kg load lifted correctly puts less pressure on the spine than a 10-kg load lifted with a bent back and outstretched arms.

The Impact of Work Attitude and the Work Environment

In addition to the lifting technique itself, the working height and the available space also play a role. Lifting from a low position, such as from the floor or a pallet, significantly increases the strain on the back. The same applies to lifting above shoulder height or in a confined space where the worker cannot stand upright. A well-designed workstation that optimizes the lifting zone can, in practice, increase the safe weight that can be handled without increasing the risk.

What are the risks of lifting heavy objects in the workplace?

Lifting heavy loads in the workplace is one of the most common causes of musculoskeletal disorders, particularly back pain and injuries to the lumbar spine. These conditions often develop gradually due to repeated strain and lead to long-term absenteeism, reduced productivity, and higher costs for the employer.

The most common risks associated with exceeding the weight limit for lifting boxes are:

• Acute back injuries: muscle tears, herniated discs, and spinal injuries caused by sudden overexertion
• Chronic Back Pain: Insidious Damage Caused by Daily Strain on the Intervertebral Discs
• Shoulder and neck pain: when lifting above shoulder height or with an asymmetrical posture
• Knee injury: caused by frequently bending down and standing up while carrying heavy loads
• Increased absenteeism: Back problems account for a large portion of long-term absenteeism in the manufacturing sector

In addition to the physical consequences for the employee, these risks also have legal consequences for the employer. If an employer can be shown to have failed to conduct a risk assessment or to have taken appropriate measures, the employer may be held liable in the event of a work-related accident or occupational disease.

When is a job analysis required for lifting activities?

A workstation analysis for lifting activities is required whenever employees regularly handle loads manually. The Codex on Well-Being at Work requires employers to conduct a risk assessment for every workstation where manual handling plays a significant role, regardless of the load’s weight. Even light loads can pose a risk if handled frequently or if the worker’s posture is poor.

In practice, a job analysis is definitely recommended in the following situations:

• Employees regularly lift loads weighing more than 10 kg
• Lifting activities are repeated several times an hour
• There have been complaints from employees about back pain or fatigue
• The work environment does not allow for optimal lifting techniques
• Vulnerable groups work at the workstation in question

The company’s prevention advisor or occupational physician plays a central role in conducting or supervising this analysis. Based on the results, specific measures are recommended, such as adjusting the work height, limiting the frequency of lifting, or using mechanical lifting aids.

What tools reduce the weight employees have to lift?

Mechanical and electrical lifting aids are the most effective way to reduce or completely eliminate the lifting load for employees. By transferring the physical strain to a machine, the risk of injury is drastically reduced, and employees can also be deployed more flexibly. The choice of the right lifting aid depends on the shape, weight, and frequency of the loads to be handled.

The most commonly used tools for lifting boxes and similar loads are:

• Vacuum lifters: ideal for lifting and moving boxes, sheets, and other flat loads without requiring physical effort from the operator
• Mobile lifts: versatile machines that raise loads to the correct working height, thereby optimizing the tilt zone
• Electric tugs: for moving heavy loads horizontally without pushing or pulling
• Ergonomic lift tables: raise pallets or boxes to the correct working height, thereby preventing lifting from a bent-over position

An overview of the products available for manual handling illustrates just how wide the range of ergonomic solutions is today. Making the right choice always starts with a thorough analysis of the specific work situation.
