Beware of Robot – WW34 Safety Sign

WW34 Beware of Robot is a workplace warning sign used to alert employees, contractors and visitors that robotic machinery may be operating in the area.

Industrial robots can move automatically, rapidly or through programmed movements. Depending on the equipment and work area, people may be exposed to hazards such as unexpected movement, impact, crushing, trapping or contact with moving robotic components.

A clearly visible WW34 sign provides an early warning before people enter or approach an area where robotic equipment is operating.

What Does the WW34 Safety Sign Mean?

WW34 means Beware of Robot. It warns people that robotic machinery may be present or operating in the area.

The sign is particularly useful around industrial robot cells, automated production lines, robotic welding equipment, palletising systems and other automated machinery.

WW34 is a warning sign and should be supported by appropriate machine guarding, restricted access, safety procedures and other controls based on the equipment and workplace risk assessment.

Why Are Robot Warning Signs Important?

Industrial robots can perform programmed movements that may not always be obvious to someone approaching the work area. A robot may move, rotate, extend an arm or operate associated equipment as part of an automated process.

WW34 provides a visible warning that automated robotic equipment is present and that people should follow the site's access and machinery safety procedures.

Warning signage does not replace physical guarding, safety interlocks, emergency stops, isolation procedures, training or supervision where these controls are required.

Where Are WW34 Robot Safety Signs Used?

WW34 signs can be used in workplaces containing robotic or automated machinery, including:

• Factories and manufacturing plants
• Automotive production facilities
• Robotic welding areas
• Automated assembly lines
• Packaging facilities
• Palletising areas
• Warehouses with robotic systems
• Material-handling facilities
• Engineering workshops
• Industrial processing plants
• Research and testing facilities
• Automated production cells

WW34 in Manufacturing Plants

Manufacturing facilities commonly use robots for assembly, welding, painting, handling, packing and other production activities.

WW34 can be installed at entrances to robotic cells and other locations where employees, contractors or visitors may approach the automated equipment.

WW34 for Robotic Welding

Robotic welding systems can combine robot movement with welding equipment, hot materials, sparks, fumes and other workplace hazards.

WW34 warns about the robotic machinery. Additional welding, heat, fire, PPE or other hazard signage should be used where those hazards are also present.

WW34 for Robotic Assembly Lines

Automated assembly lines may contain several robots operating together with conveyors, sensors, tooling and other machinery.

WW34 can help identify the robotic work zone before people enter the area.

Where access is restricted, appropriate barriers, gates, interlocks and access-control procedures should also be used.

WW34 for Robotic Palletising and Packaging

Robotic palletisers and packaging systems may move materials automatically and can have defined operating zones around the robot and associated equipment.

WW34 can be positioned at suitable access points to warn people before they approach the automated system.

WW34 and Robot Cells

A robot cell is a defined working area containing a robot and often other equipment such as conveyors, fixtures, tooling and sensors.

WW34 can be displayed around the perimeter or access points of the robot cell to communicate the presence of robotic machinery.

Where entry is controlled, the warning sign should work together with the cell's physical safeguarding and access-control system.

WW34 and Automated Machinery

Robotic systems are often integrated with other automated machinery. A robot may interact with conveyors, presses, cutting equipment, welding systems or material-handling equipment.

The safety controls should therefore consider the complete automated system rather than the robot alone.

WW34 and Unexpected Robot Movement

Robot movement may be initiated automatically as part of a programmed sequence or production process.

People should not enter a robotic operating zone unless they are authorised and are following the applicable access and isolation procedures.

The specific controls depend on the robot, programming system, guarding, task and workplace risk assessment.

WW34 and Machine Guarding

Physical guarding is an important safety control around many industrial robot applications.

Guarding can help prevent people from entering dangerous areas while the robot or associated machinery is operating.

WW34 should not be used as a replacement for guards, barriers or other protective devices required for the machinery.

WW34 and Safety Interlocks

Some robotic systems use interlocked gates or other safety devices that stop or prevent operation when an access point is opened.

These systems should be maintained and tested according to the manufacturer's instructions and the site's machinery safety procedures.

WW34 and Robot Maintenance

Maintenance work can require people to enter areas that are normally protected from access while the robot is operating.

Before maintenance, repair, cleaning or adjustment, workers should follow the site's isolation, lockout and safe-work procedures applicable to the equipment.

Where machinery could move or become energised unexpectedly, appropriate measures should be taken to prevent people from being injured.

WW34 and Contractors

Contractors may be unfamiliar with a factory's automated systems and may not know where robotic work cells are located.

A visible WW34 sign provides a simple warning before contractors approach the machinery and can support site induction and access-control procedures.

WW34 and Visitors

Visitors may not have received detailed training on the operation of industrial robots.

WW34 can alert visitors that automated machinery is present and that they should remain outside restricted areas unless accompanied or authorised.

Where Should a WW34 Sign Be Placed?

WW34 should be positioned where people can see the warning before entering or approaching the robotic machinery area.

Suitable locations may include:

• Robot-cell entrances
• Factory production areas
• Automated assembly lines
• Robotic welding cells
• Packaging and palletising areas
• Maintenance access points
• Gates and barriers around robotic equipment
• Pedestrian approaches to automated machinery

The sign should remain clearly visible and should not be hidden by machinery, guarding, doors, stock or other structures.

WW34 and Restricted Access

Some robotic machinery areas may only be accessible to trained, authorised or otherwise suitably controlled personnel.

WW34 can be displayed together with No Unauthorised Entry, Restricted Area or Authorised Personnel Only signs where applicable.

WW34 and Emergency Stops

Robotic systems may have emergency-stop devices that allow machinery to be stopped during an emergency.

Emergency-stop arrangements should be clearly identified and maintained according to the equipment's safety design and workplace procedures.

The warning sign itself should not be confused with an emergency-stop instruction or emergency-control device.

WW34 and PPE

WW34 is a warning sign and does not by itself specify which personal protective equipment must be worn.

Depending on the robotic process, workers may require eye protection, hearing protection, safety footwear, gloves, protective clothing or other PPE.

Where specific PPE is mandatory, the appropriate mandatory PPE safety sign should be displayed separately.

WW34 for Industrial Automation

Industrial automation can combine robots with sensors, programmable controls, conveyors, machinery and automated material-handling systems.

WW34 can form part of the hazard communication system around automated work cells where robotic equipment is present.

WW34 for Warehouses

Modern warehouses may use automated robotic systems for picking, transporting, sorting or palletising goods.

WW34 can help identify areas where robotic equipment operates and where pedestrian access may be controlled.

WW34 in Engineering Workshops

Engineering and fabrication facilities may use robotic welding, cutting, handling or other automated systems.

WW34 can be displayed around these work areas to warn employees and visitors about robotic machinery.

WW34 and Other Machinery Hazards

A robotic system may contain several hazards in addition to robot movement.

Depending on the equipment, additional signs may be needed for moving machinery, hot surfaces, electrical hazards, welding, fire, noise, chemicals or restricted access.

The selected signage should match the actual hazards identified at the workplace.

Indoor and Outdoor WW34 Safety Signs

WW34 can be used for both indoor and outdoor robotic machinery applications.

Indoor applications include factories, automated production plants, workshops, warehouses and laboratories. Outdoor applications may include automated industrial yards, manufacturing compounds and specialised material-handling areas.

For outdoor installations, the sign material should be selected according to exposure to sunlight, rain, wind, dust and temperature changes.

WW34 Safety Sign Materials

WW34 signs can be manufactured in materials suitable for the installation environment and mounting surface, including:

• Aluminium
• PVC or suitable plastic
• Coated metal
• Self-adhesive vinyl for suitable surfaces

The appropriate material depends on the location, mounting method and environmental conditions.

WW34 Sign Size and Visibility

The appropriate WW34 sign size depends on viewing distance, the layout of the robotic area and surrounding conditions.

The sign should be positioned within the normal line of sight and remain visible before people reach the robot operating area.

Custom Robot Warning Signs

Businesses may require additional wording such as Robot in Operation, Automated Machinery, No Unauthorised Entry or other site-specific instructions.

Signs4SA can assist with custom WW34 robot warning signs in different sizes and materials for factories, warehouses, workshops, manufacturing facilities and industrial sites.

WW34 and South African Workplace Safety

WW34 is identified as the Beware of Robot safety sign in the South African WW warning-sign series.

The Department of Employment and Labour is the relevant regulator for occupational health and safety in South African workplaces. The Driven Machinery Regulations, 2015 provide requirements for machinery used in workplaces, including precautions for people working on or near moving machinery and measures intended to prevent accidental starting. ([gov.za](https://www.gov.za/documents/notices/occupational-health-and-safety-act-regulations-driven-machinery-24-jun-2015))

The South African Government published draft General Machinery Regulations in 2025 as a proposed replacement for the older General Machinery Regulations. Because the draft was issued for public comment, the requirements applicable to a specific robotic installation should be checked against the regulations and standards in force at the time. ([labour.gov.za](https://www.labour.gov.za/Media-Desk/Media-Alerts/Pages/Department-of-Employment-and-Labour-invites-public-comments-on-the-repeal-of-the-General-Machinery-Regulations.aspx))

The correct warning sign, guarding, access controls, isolation procedures, training, PPE and other safety measures should be determined according to the robotic system, workplace risk assessment and applicable South African requirements.

WW34 vs Other Machinery Warning Signs

Different signs communicate different hazards:

• WW17: Warning of Moving Machinery
• WW20: Beware of Fork-Lifts
• WW30: Beware of Magnetic Crane
• WW34: Beware of Robot

WW34 should be used where the specific hazard involves robotic machinery.
