4. Task-Specific Hazards and Controls

Hazard	Risk	Control Measures
Fall from height	Serious injury or death	Use fall protection systems such as guardrails, safety nets, or personal fall arrest systems when working 6 feet (1.8 m) or more above lower levels [2]. Ensure proper use of body belts or harnesses, lanyards, and anchorage points [2].
Falling objects	Injury to workers below	Use toeboards to prevent tools and materials from falling [2]. Secure all tools and materials to prevent them from falling. Establish a drop zone and restrict access to the area below.
Structural instability	Collapse of the roof structure	Ensure that any component designed to support a part of the project is completed before adding to the load on that part [1]. Brace free-standing walls or structures adequately to prevent collapse [1]. Consult with an engineer for bracing or shoring design if necessary [1].
Improper scaffold use	Falls, scaffold collapse	Ensure scaffolds are erected and used according to regulations. Use ladder jack scaffolds below 20 feet [3]. Inspect scaffold components before use [4].
