A scale starting from 0 to 6 was made for assigning a DOFD, with 0 indicating no noticeable injury and six indicating full usage. 30-nine “beginner” raters carried out an Examination of injury to a wall area, completing sixty six rankings very first without the DOFD process and 2nd, recurring rating While using the new DOFD process. The outcome indicated that the newbie raters have been a lot more trustworthy within their Examination in the DOFD to gypsum wallboard when using the DOFD technique. These effects assistance using standardized processes to reduce the variability in info assortment and interpretation.
You can find also an Interfire Web site that characteristics specialised article content on fire and arson, search engines like google and yahoo for investigate, links to Web sites containing recalls on harmful goods and auto recalls, MSDS sheets, similar education opportunities and even more.
