OSHA (Occupational Safety and Health Administration) has guidelines and regulations for the use of hand and power tools in the construction industry to prevent injuries. Some key points include:

Employers must provide workers with training on the proper use and maintenance of tools
Tools must be maintained in good condition, and defective tools must be removed from service
Workers must use the appropriate personal protective equipment (PPE) when using tools
Workers must use the correct tool for the job and follow the manufacturer's instructions
Power tools must be equipped with safety features, such as guards and switches, and must be used in accordance with OSHA regulations

Workers must be aware of their surroundings and avoid tripping hazards or other dangers when using tools
Workers must be aware of the hazards associated with working with electrical equipment, such as power tools and extension cords, and must use them properly to prevent electrical shock and other hazards
It's important to note that OSHA's regulations are the minimum safety requirements and employers should strive to go beyond these regulations to ensure a safe work environment.
