Some features in new federal fall-protection rules for homebuilding and roofing:

• Workers more than 6 feet above the ground must be protected by guardrails, safety nets or other acceptable means.

• Employers who consider rules not feasible or worry that they create greater hazards can devise site-specific protection plans that must meet OSHA approval. (Cost is insufficient grounds to consider a rule not feasible.)

• Workers must be trained in avoiding falls and using protection equipment. Documentation of training must be available.

• Employers have the option of their workers operating from scaffolds, ladders or aerial lifts.

• $7,000 maximum penalty for serious violations with reductions for "good faith efforts."
