WET WEATHER CONDITION PRECAUTIONS
Heavy rain can create real challenges on construction sites. The recent wet weather may be causing poor ground conditions and may have a serious impact on construction sites – causing roll-over hazards, injury, costs, and delayed schedules. Site planning and identifying the right solutions for wet weather are essential in mitigating unsafe working conditions.
Ground conditions can change overnight.
For any outdoor job site, ground conditions should be included in the daily hazard assessment.
- Clearly identify and post project entry signage.
- Ensure there are adequate clearances and overhead wires are marked.
- Prepare safe, hazard free approaches for Cemstone vehicles at your jobsite. Once you request our vehicles(s) to move past the curb line or right of way limits, Cemstone is not liable for any damage.
- Proper drainage systems should be in place to prevent standing water.
- Identify uneven or unstable areas (including freshly moved soil, utility boxes, septic tanks, etc), and then fix, cover, barricade, re-route, or make equipment adjustments accordingly to ensure worker safety.
- Use ground protection mats over muddy, slippery, or uneven areas. Cover or guard all holes at the job site that are trip hazards for workers or tip-over hazards for equipment.
- Remove stones and rubble that are creating uneven ground conditions or create an alternate route for personnel and equipment. Clear tall grass or brush on the job site that could be covering hidden dangers like holes, sharp objects, snakes, or other wildlife.
The ground at a job site can become difficult or even dangerous for many different reasons, including:
• Uncompacted fill when soil or other material is backfilled into a trench without compaction
• Excess water on site from rain, flooding, or operational activities that use water
• Vibration from heavy machinery, equipment, or vehicles on the job site
• Sloping or uneven terrain
• Structural collapse causing hidden dangers and adding stress to the ground
• Nearby excavations may weaken the surrounding ground
• Unguarded holes create trip and tip-over hazards
Open and effective communication channels with suppliers, contractors, and customers can help manage the impact of rainy weather. This includes having clear communication about any changes in schedules or delays that may be caused by weather-related factors. Identify the truck and/or pump route on your jobsite. Have your spotter ready upon our arrival to ensure our employee(s) and your project team members are safe. Cemstone requires spotters for our drivers and operators. Please share the information below with your spotters.
• Driver should not backup without a spotter
• Driver and spotter MUST always maintain visual contact
• If driver loses sight of the spotter, they should STOP IMMEDIATELY
• Driver WILL NOT RESUME BACKING until visual contact with the spotter is reestablished
• Use only ONE Spotter
• Each pour should have a competent designated spotter communicating with the driver
• Spotter should never get between rear of mixer and other object to avoid crushing accidents
• Spotter should continuously check ground conditions to avoid slipping or falling while walking backwards
• Driver should make sure the spotter knows the proper hand and arm signals If a driver does not understand spotter’s signal(s), they must STOP IMMEDIATELY AND
• Explain proper hand signals to spotter
• The spotter and driver must agree on how close the rear of the truck should be from an object.
