While my knowledge base doesn't contain specific documentation on bolt installation and tightening procedures, including torque specifications and regulatory compliance, I can provide general safety guidance based on industry best practices.

Potential safety hazards during bolt installation and tightening include:

• Crushed hands and arms, severed fingers and limbs, lacerations and abrasions can occur if safeguards are not in place when using machinery.
• Struck-by hazards: During bolt tightening, workers may be struck by tools or materials.
• Caught-in or -between hazards: Workers can be caught in pinch points or shear points by moving parts of machinery.
• Eye injuries: Flying chips or scrap material can strike the head, particularly the eyes or face, during bolt installation or tightening.
• Slips, trips, and falls: Poor housekeeping around the work area can lead to slips, trips, and falls.
• Electrical hazards: Power tools can present electrical hazards if not properly maintained or used near power lines.

General safety guidelines to mitigate these hazards:

• Use appropriate PPE: Wear safety glasses or face shields, gloves, and head protection.
• Maintain tools properly: Keep tools sharp and clean for best performance.
• Ensure proper machine guarding: Guards must not create potential hazards and must be attached to the machine where possible.
• Practice good housekeeping: Keep floors, walkways, and stairs in good repair and free of slip or trip hazards.
• Provide adequate lighting: Maintain adequate lighting in all work areas.
• Inspect scaffolding daily: All scaffolding should be inspected daily by a competent person.
• Maintain a safe distance from power lines: Stay at least 10 feet away from overhead power lines and use non-conductive ladders when working near power lines.
