In daily warehouse and logistics handling scenarios, most operation misjudgments and minor safety risks related to electric forklifts come from inconsistent communication rather than equipment failures. Standardizing the unified language and signal system for all electric forklift operators and on-site coordinators can effectively eliminate information deviation, create a more orderly operation environment, and reduce unnecessary operation delays.

First, it is necessary to formulate clear and unified verbal language specifications for all relevant personnel. All operation instructions should avoid ambiguous, colloquial or customized expressions that may cause misunderstanding, and replace fuzzy descriptions with clear, quantifiable and unified terms. For example, it is not allowed to use vague words such as "move a little forward" to give operation instructions, but use clear descriptions such as "move forward 2 meters at low speed". In the noisy working environment of large warehouses, operators and ground coordinators can use dedicated intercom equipment for communication, every instruction issued must get a clear confirmation reply from the recipient before the corresponding operation is executed. All personnel must not use private slang or temporary created terms in public operation scenarios, and all standardized terms should be printed into a manual for all new employees to learn systematically before taking up their posts.

Second, it is required to unify the non-verbal signal standards for scenarios where visual contact is needed or voice transmission is blocked. All hand signals, light signals and whistle signals used on the operation site must refer to common safety operation norms, and no individual customized signals that have not been notified to all personnel are allowed to be used. The signal personnel who guide the forklift operation at a long distance must wear obvious recognizable identification, and all action instructions must be made within the visible range of the forklift operator. The unified basic signals include: raising the straight arm vertically to indicate lifting the fork, extending the flat arm horizontally to indicate moving the vehicle horizontally, making a fist and circling above the head to indicate immediate emergency stop, waving both hands down repeatedly to indicate lowering the fork. All signals should be kept simple and easy to identify, to avoid the situation that the operator cannot distinguish the action meaning of the signal in the process of high concentration of operation.

Third, establish a regular assessment and dynamic update mechanism for language and signal specifications. The management team should organize a regular 30-minute review training every month for all on-site operators and coordinators, to test their mastery of standardized language and signals, and correct the wrong expression habits found in daily work in time. When new operation scenarios, new handling equipment or new personnel join the site, the management team should publicize and confirm the current unified specification rules in the pre-shift meeting of the day, and collect reasonable feedback from frontline operators to optimize the content of the specification continuously. The implementation of this standardized system does not require excessive additional operation cost, but can effectively reduce the probability of operation collision, material damage and personnel injury, and help the entire logistics handling process run more smoothly and orderly.
