BOISE, Idaho -

An Idaho construction company is formally appealing findings that it failed to properly train and protect its employees.
   
The Idaho Statesman reports that the U.S. Occupational Safety and Health Administration found a lack of training by Hard Rock Construction was a factor when two workers died in a Boise trench collapse.
   
Bert Smith Jr. of Caldwell and Ernesto Saucedo of Nampa were killed when the 9- to 11-foot deep trench they were working in collapsed on May 3. A third worker was injured but survived. Local OSHA head Dave Kearns says the third worker is probably permanently disabled.
   
OSHA has issued $77,319 in fines against Hard Rock.
   
The company didn't return a call from The Associated Press on Thursday.
