Quick Answer
Yes, using tarps in high winds poses safety concerns, including tarp failure, loss of shelter, and wind-borne debris, which can lead to injury or death.
Tarp Failure Risks
When exposed to high winds, tarps can fail due to the force exerted on them. This risk increases when using a tarp that is undersized for the structure it’s intended to protect. A general rule of thumb is to ensure the tarp is at least 10% larger than the structure it covers to account for wind deflection. For example, a 12x16 foot tarp should be used for a 10x14 foot structure to provide a 10% safety margin.
Securing the Tarp
To minimize the risk of tarp failure, it’s essential to secure it properly. This includes using multiple tie-down points, such as stakes and ropes, to anchor the tarp to the ground. Aim for a maximum of 10 staking points for a standard-sized tarp, spaced evenly apart to distribute the force of the wind. Use a minimum of 3/4 inch diameter stakes and secure the tarp with a minimum of 100 pounds of holding force per stake.
Wind-Resistant Tarp Options
If you’re planning to use a tarp in high winds, consider using a wind-resistant option, such as a reinforced tarp with a waterproof coating. These tarps are designed to withstand higher wind speeds and are often made with heavier-duty materials. Some examples of wind-resistant tarps include those with a wind rating of 50 mph or higher and a waterproof coating that meets or exceeds the standards set by the Waterproofing and Coatings Association. Always follow the manufacturer’s instructions for securing and using these tarps.
