Controlling the risk of moving object accidents in a construction project involves several key steps, including:

1. Identify potential moving object hazards: The first step is to identify the areas and equipment where moving objects may present a hazard. This may involve reviewing equipment operation manuals, identifying moving machinery, and assessing vehicle traffic patterns.
2. Implement engineering controls: Engineering controls, such as installing barriers, signage, and warning systems, should be used to control the movement of objects. This may involve the use of automatic shut-off switches, backup alarms, and traffic control devices to prevent accidental collisions.
3. Provide personal protective equipment (PPE): Workers should be provided with PPE, such as high visibility clothing and hard hats, to protect against moving object hazards. PPE should be appropriate for the specific hazard and level of exposure.
4. Develop safe work procedures: Safe work procedures should be developed for working around moving objects. This may involve developing procedures for operating machinery and vehicles, as well as procedures for working in close proximity to moving equipment.
5. Provide training: Workers should be trained on the hazards associated with moving objects, how to use PPE, and the safe work procedures that have been developed. Training should be provided to all workers who may be exposed to moving object hazards.
6. Monitor and review: Regular monitoring and review should be conducted to ensure that the controls that have been put in place are effective in controlling moving object hazards.
7. Emergency response plan: An emergency response plan should be developed in case of incidents involving moving objects. Workers should be trained on the plan and it should be regularly reviewed and updated as needed.

Overall, controlling the risk of moving object accidents in a construction project requires a comprehensive approach that includes hazard identification, engineering controls, PPE, safe work procedures, training, monitoring, and emergency planning.
