Here is a risk assessment in a table format for curtain wall module installation using a mini-crane, considering the crane operates on floors above the installation level:

Task/Hazard	Risk	Preventive Measures	Equipment	Monitoring & Review
Lifting and Placement of Curtain Wall Modules
Unstable crane setup	Crane tipping, module dropping [1]	Ensure proper ground conditions, use outrigger pads, conduct pre-lift inspection [2]	Outrigger pads, level, crane inspection checklist	Regular inspections of setup, daily checks
Overloading crane	Crane failure, module dropping	Adhere to load chart, calculate load weight accurately [3]	Load chart, weighing scales	Continuous monitoring during lifts
Module swinging	Loss of control, impact with structure	Use tag lines, controlled crane movements	Tag lines	Observe module stability during lifting
Working at Heights
Falls from height	Injury or fatality [4]	Use of fall arrest systems, guardrails, safety nets, ensure proper training 1, 3, 7	Harness, lanyard, anchor points, guardrails, safety nets	Regular inspections of fall protection equipment [5]
Dropped objects	Injury to people below	Use tool lanyards, toe boards on platforms, exclusion zones [6]	Tool lanyards, toe boards, barriers, signage	Regular checks of securing methods
Crane Operation
Crane malfunction	Crane failure, module dropping	Regular crane inspections, pre-shift checks, qualified operator 2, 15	Crane inspection logs	Scheduled maintenance, daily checks
Two-blocking	Cable damage, load dropping	Use anti-two block device, train operator [7]	Anti-two block device	Regular checks of device functionality
Environmental Factors
Wind	Loss of control, crane instability	Monitor wind speed, reduce load size, postpone lifts in high winds	Anemometer	Continuous monitoring of weather conditions
Slippery surfaces (ice, rain)	Slips, trips, falls	Clear surfaces, use non-slip footwear, postpone lifts in adverse conditions	Non-slip footwear	Regular checks of walking surfaces
General Safety
Communication breakdown	Miscommunication, accidents	Use clear hand signals, radios, pre-lift meetings [7]	Radios, hand signal charts	Ensure all personnel understand communication protocols
Unguarded swing radius	Struck by crane	Implement swing radius barriers, spotters [3]	Barriers, spotters	Monitor crane movement, enforce barrier use
Emergency response	Delayed response, increased injury	Establish emergency plan, conduct drills, ensure first aid availability	First aid kit, emergency contact list	Regular review and drills of emergency plan

Additional Considerations:

• Fall Protection Plan: Develop a detailed fall protection plan specifying hazards, systems, anchorages, clearance distances, and rescue procedures [4].
• Competent Person: Ensure a competent person supervises the work and monitors safety [8].
• Training: Provide comprehensive training on crane operation, rigging, fall protection, and emergency procedures [8].
• Equipment Inspection: Regularly inspect all equipment, including the crane, rigging, and fall protection gear, before each use [5].
• Weather Monitoring: Continuously monitor weather conditions and halt operations during high winds or adverse weather [9].
• Communication: Establish clear communication protocols between the crane operator, riggers, and installation crew [7].
• Load Chart Adherence: Strictly adhere to the crane's load chart and never exceed its lifting capacity [3].
• Emergency Plan: Develop and communicate a detailed emergency response plan, including rescue procedures [8].
• Housekeeping: Maintain a clean and organized work area to prevent trips and falls [6].
• Personal Protective Equipment (PPE): Ensure all workers wear appropriate PPE, including hard hats, safety glasses, and high-visibility clothing [6].

This table provides a starting point. A comprehensive risk assessment should be conducted on-site, considering the specific conditions and tasks involved.
