Why is Communication Important in Crane Operations?
Effective communication is fundamental to safe crane operations, particularly where the crane operator cannot maintain a clear view of the lifting procedure. Where signalling is required, a competent signaller communicates agreed manoeuvring instructions to the crane operator, helping the lifting operation to be carried out in accordance with the planned system of work.
The Health and Safety (Safety Signs and Signals) Regulations 1996 require employers to use safety signs and signals where risks cannot be adequately controlled by other means. Where visual signalling forms part of the selected control measures, recognised hand signals can be used to direct crane manoeuvres.
BS 7121-1 provides recognised guidance for crane operations, including hand signalling. HSE guidance also recognises the hand-signal code set out in Schedule 1 of the Safety Signs and Signals Regulations.
The Risks of Miscommunication On Site
Miscommunication between a crane operator and signaller can pose a significant risk to people and high-value assets on site. Key risks include:
- Dropped loads: Incorrect instructions may cause a load to be lowered, released or moved unexpectedly, which could result in serious injury or fatality, as well as damage to the load or surrounding property.
- People being hit by the crane or its load: Miscommunication can cause the crane or suspended load to move unexpectedly, potentially resulting in the crane or load striking workers, vehicles or members of the public.
- Crushing and trapping: Personnel may become trapped between the load and another object if the crane moves in the wrong direction or at the wrong time, putting them at risk of injury or requiring an emergency stop.
- Load swing: Poorly coordinated movements can contribute to unexpected or excessive load swing, increasing the risk of the load striking people, structures or other equipment.
- Collisions: The crane’s boom, jib or load may collide with buildings, scaffolding, plant, vehicles, other cranes or overhead services, causing damage to the crane or the surroundings.
- Project delays: Lifting operations may need to stop while communication issues are resolved or while unclear signals are confirmed, causing programme delays and increased costs.
How Effective Communication Helps Health & Safety
Effective communication is an important safety control during lifting operations. By providing clear, recognised instructions, hand signals reduce the risk of misunderstandings and contribute to well-controlled operations. This is particularly beneficial in lifts where the operator cannot see the entirety of the load and lifting area.
The signaller monitors the manoeuvre from a suitable position and communicates the agreed instructions to the crane operator while supporting the defined safety arrangements around the movement.
Designated hand signals convey an immediate message to the crane operator. This is particularly important in emergency situations. The recognised emergency-stop signal provides an immediate visual instruction to stop movement where danger is identified.
Crane Hand Signals Overview
The Health and Safety (Safety Signs and Signals) Regulations 1996 set out a recognised code of hand signals that can be used for hazardous manoeuvres. Where this signalling code is selected, the signals should be understood and used consistently by those involved. Examples of how these hand signals are used include:
- When the crane operator has a restricted view of the site or load
- As part of routine lifting operations
- In situations where verbal communication isn’t suitable
- In combination with radio communication
- To communicate the need for an emergency stop by any worker on-site
Who is Responsible for Giving Hand Signals?
A designated competent signaller is responsible for communicating agreed manoeuvring instructions to the crane operator. Where one person also undertakes slinging duties, they must be competent for the responsibilities assigned to them.
The Safety Signs and Signals Regulations state that the signaller must be able to monitor all manoeuvres visually without putting themselves at risk. If one signaller cannot monitor all the required manoeuvres safely, additional signallers may be used. In those circumstances, the communication arrangements should clearly establish who is directing the operator at each stage.
The only exception to signalling responsibility is emergency stop signals. The crane operator should immediately cease operations if this signal is communicated by anyone on site.
Under LOLER, every lifting operation needs to be properly planned by a competent person, appropriately supervised and carried out in a safe manner. Competent signalling arrangements can form part of the safe system of work but do not replace the separate LOLER requirements for proper planning, appropriate supervision and safe execution.
Common Crane Hand Signals
Schedule 1 of the Health and Safety (Safety Signs and Signals) Regulations 1996 includes the following recognised hand signals:
| Start | Both arms are extended horizontally with the palms facing forwards. |
| Stop | The right arm points upwards with the palm facing forwards. |
| Right to the Signaller | The right arm is extended approximately horizontally with the palm facing downwards and slowly makes small movements to the right. |
| Left to the Signaller | The left arm is extended approximately horizontally with the palm facing downwards and slowly makes small movements to the left. |
| Emergency Stop | Both arms point upwards with the palms facing forwards. |
| End of Operation | Both hands are clasped at chest height. |
| Raise | The right arm points upwards with the palm facing forwards and slowly makes a circle. |
| Lower | The right arm points downwards with the palm facing inwards and slowly makes a circle. |
| Move Forwards | Both arms are bent with the palms facing upwards, and the forearms make slow movements towards the body. |
| Move Backwards | Both arms are bent with the palms facing downwards, and the forearms make slow movements away from the body. |
| Vertical Distance | The hands indicate the relevant distance. |
| Horizontal Distance | The hands indicate the relevant distance. |
| Slow | All movements are made slower. |
| Quick | All movements are made faster. |
Best Practices for Crane Hand Signals Safety
Maintain Clear Visibility
Where hand signals are being used, the crane operator must be able to recognise the signaller clearly, while the signaller must be able to monitor the manoeuvres visually from a position that does not place them at risk. The signaller should be able to see the surrounding work area, the crane and load from a safe vantage point. If this isn’t possible, alternative communications and additional signallers may be required.
Use a Designated Signaller
A dedicated signaller provides a crane operator with one point of reference for communication, ensuring they receive consistent and clear instructions throughout the lift. Emergency stop instructions are the one exception to this rule. Where additional signallers are required, the arrangements should make clear which signaller is providing instructions to the operator.
Confirm Signals Before Lifting
The communication method and signals used during the lift should be confirmed as part of the lift planning stage. The crane operator and signaller should understand the agreed signalling code and communication arrangements for the planned lifting operation.
Avoid Improvised Gestures
Improvised gestures can cause confusion and result in unexpected movement of the crane, which increases risk. Use the agreed recognised signalling code consistently. Where additional signals are genuinely required, they should be defined and understood in advance rather than improvised during the manoeuvre.
Wear Appropriate High-Visibility PPE
The signaller should be readily identifiable to the operator using suitable distinctive items. High-visibility clothing may be required where lighting, weather or site conditions affect visibility, while items such as reflective armbands or signalling bats can provide additional identification where suitable.
Training
Anyone responsible for giving or receiving lifting instructions should be competent in the agreed communication method, with signallers trained in the correct use of the signalling code selected for the operation. The HSE L64 guidance advises that individuals using hand signals should complete training on their use. New employees who have previously worked using a different recognised signalling system should receive retraining where necessary.
Alternatives or Additions to Hand Signals
There is a range of alternatives or additions that crane operators and signallers can use for clear communication. These include:
- Voice communication: Direct or transmitted verbal instructions can be used where the agreed messages can be heard and understood reliably
- Two-way radios: Used where hand signals cannot be seen clearly, such as during blind lifts
- Additional signallers: Where one signaller cannot monitor all required manoeuvres safely, further competent signallers can support the agreed communication arrangement
Creating Safer Communication in Crane Operations
Clear, planned communication can help reduce on-site risk and support the protection of workers and valuable assets. Some of the steps you can take to improve safety through communication include the following:
- Selecting the communication method during lift planning
- Recording the agreed arrangements in the lift procedure or method statement where required
- Confirming the communication arrangements during the pre-lift briefing
- Providing suitable initial and refresher training
- Reviewing communication arrangements when site conditions or the lifting operation change
- Ensuring the signaller can be clearly identified
