Write a safe work procedure for genset lifting in Hong Kong

A safe work procedure for lifting and hoisting a generator set in Hong Kong should be based on a site-specific risk assessment, a documented lifting plan, competent supervision, verified load data, inspected lifting gear, controlled lifting operations, and strict exclusion of non-essential persons from the fall zone and swing radius. Before work starts, identify hazards such as overhead power lines, nearby structures, poor ground conditions, weather, pinch/crush points, unstable load center of gravity, and public exposure. A hazard assessment should be completed before rigging and moving loads, and personnel must understand their roles and the hazards related to rigging and hoisting before the lift begins. The load route and landing area should be planned so exposure to suspended loads is minimized. [1] [2] [3]

• Prepare a task-specific risk assessment covering load weight, center of gravity, lifting points, crane position, outrigger loads, ground bearing capacity, access/egress, overhead electrical hazards, weather, visibility, nearby traffic/public interface, and emergency arrangements.
• Develop a lifting plan before the job. For routine lifts this may be a standard plan; for heavy, complex, tandem, restricted-space, or high-risk lifts it should be a detailed engineered plan with crane configuration, radius, boom length, rigging arrangement, communication method, exclusion zone, and step-by-step sequence.
• Verify the generator set weight from manufacturer data, nameplate, shipping documents, or certified drawings before selecting the crane and rigging. Include fuel, coolant, batteries, acoustic enclosure, base frame, and any attached accessories or skids in the total lifted weight.
• Confirm the crane capacity from the applicable load chart at the actual operating radius and configuration. The load chart must be available to the operator at the control station.
• Ensure the crane is set on firm, level ground with outriggers/stabilizers fully deployed, supported, blocked, and locked in accordance with manufacturer recommendations.
• Inspect all lifting gear before use, including slings, shackles, hooks, master links, spreader beams, eyebolts, and tag lines. Use only gear with legible safe working load identification and remove defective gear from service.
• Use the genset manufacturer's designated lifting points only. If no certified lifting points are available, do not improvise; obtain manufacturer instructions or engineer approval for the lifting method.
• Rig the load so it is balanced, secured against shifting, and lifted through or in relation to its center of gravity. Use spreaders where needed to avoid side loading, crushing, or damage to the genset frame or enclosure.
• Provide a qualified/competent lifting team: crane operator, lifting supervisor/lift director, qualified rigger, and a trained signalman where the operator does not have a full view or where site conditions require one designated signaler.
• Establish and barricade an exclusion zone covering the load path, landing area, crane swing radius, and fall zone. Only personnel essential for hooking, unhooking, or guiding the load should enter, and nobody should stand directly under a suspended load.
• Use standard hand signals or reliable radio communication. One designated signalman should control the lift, except that any person must be able to give an emergency stop signal.
• Carry out a test lift just clear of the ground to confirm balance, rigging integrity, brake function, crane stability, and clearance before continuing.
• Control load movement with tag lines where needed, provided their use does not create additional hazards.
• Stop the lift if wind, lightning, poor visibility, equipment malfunction, unexpected load shift, communication failure, or unsafe ground conditions arise.
• Land the genset on a prepared, level, load-bearing surface. Keep hands and feet clear of pinch points during landing and de-rigging.
• If installation, maintenance, or connection work exposes workers to electrical or mechanical energy, apply lockout/tagout or equivalent isolation before working on the genset or connected systems.

[2] [5] [2] [1] [1] [3] [6] [1] [13] For crane and rigging operations, the appointed lifting supervisor should brief the team before the lift, confirm the lifting plan, verify that the operator has the correct load chart and configuration, and ensure the rigger has identified the load weight and center of gravity. The crane operator should not lift beyond rated capacity, should keep focused on crane motion, and should stop immediately if signals are unclear or unsafe conditions develop. The rigger should ensure proper attachment to the hook, edge protection where needed, and tag line installation when load control is required. If the operator's view is obstructed, or site-specific concerns exist, a qualified signal person is required. During the lift, no one should travel or work directly under the load, and access to the swing radius and lift zone should be restricted. [2] [2] [12] [3] [2]

For lifting gear inspection and load verification, use only lifting appliances and lifting gear that are suitable, properly maintained, and identifiable. Check slings, chains, hooks, shackles, eyebolts, spreaders, and lifting lugs for deformation, cracks, wear, corrosion, damaged latches, illegible markings, or other defects before use. Defective gear must be removed from service. Verify the genset lifting points are in good condition and use the manufacturer's specified lifting arrangement. Know the exact weight before hoisting and ensure every component in the lifting system is capable of supporting that weight with adequate margin. A trial lift just above ground level is good practice to confirm balance and stability before slewing or traveling the load. [1] [1] [8] [8] [11]

For personnel, competency, permit, and PPE, the Hong Kong lifting operation should be controlled by an appointed competent person/lifting supervisor, with a trained crane operator, qualified rigger, and designated signalman. A permit to work is strongly recommended for non-routine, high-risk, congested, night-time, public-interface, or critical lifts, and should confirm the approved lifting plan, crane certification/inspection status, lifting gear status, ground conditions, exclusion zone, communication method, weather limits, and emergency arrangements. Minimum PPE normally includes safety helmet, high-visibility vest, safety footwear, gloves suitable for rigging, and eye protection; hearing protection should be used where noise exposure is significant. PPE should follow a hazard assessment, workers must be trained in its use and limitations, and damaged PPE should be replaced. [1] [11] [4] [4] [10] [9]

For emergency procedures, stop the lift immediately if there is equipment failure, loss of communication, unstable ground, excessive wind, lightning, unexpected load movement, or any person entering the danger zone. Lower the load to a safe position if possible, isolate the area, and do not resume until the cause has been assessed and corrected by a competent person. The lifting team should know the emergency stop signal, rescue arrangements, first-aid arrangements, and site contact/escalation process. An escape route should always be maintained for workers involved in the lift. [1] [5] [7]

For Hong Kong legal compliance, the operation should comply with the general duties under the Occupational Safety and Health Ordinance and the Factories and Industrial Undertakings Ordinance, together with the Factories and Industrial Undertakings (Lifting Appliances and Lifting Gear) Regulations, the Construction Sites (Safety) Regulations, and any applicable Codes of Practice issued by the Labour Department. In practical terms, this means the employer/contractor should ensure the crane and lifting gear are of good construction, suitable strength, properly maintained, thoroughly examined and tested as required, clearly marked with safe working loads, and used only by trained and competent persons under proper supervision. A lifting plan, risk assessment, exclusion zone, safe signaling system, and documented inspections should be in place. Because your supplied documents are not Hong Kong statutes, they support the operational controls above, but the final procedure on site should be checked against the current Hong Kong legal requirements, including statutory examination intervals, approved forms/certificates, and any requirement for a competent examiner or competent person under Hong Kong law.
