NAR Safety Grant - Welding Blankets for Fire Prevention:


From the Grant Application:

5. Brief description of the safety problem that you are trying to solve:

                Occasionally we have small fires due to the dry grass on our field. We quickly put out these fires with a water sprayer and several people stomping on the flames but we would like to stop these fires from forming at all. We cannot rake back a dirt area because we cannot disturb our owner’s grass field. As an idea, we could blanket a large enough area around the launch pads with fire protection shields such as a welding blanket/shield to prevent the sparks from hitting the grass. These welding shields range in size from 3’x4’ to 6’x9’. They could also be made to a custom size. Their temperature protection range goes from 1000F to 1800F. See –

http://steelguardsafety.com/welding-blankets.htm

                For this grant we would purchase several different types and document the results. If this is successful this might be a new method of controlling fires at the source. This particularly would be good for sparky type motors since these welding blankets are made for that type of spark.  

6. Describe any matching resources your section can provide (funds, building sessions for assembling equipment, and components of a safety system):

                We would provide the resources to test the welding blankets and document the results.
