Ignore it if it doesn't affect the visible work
Charge double the standard rate without notice
Fix it and add to the final bill

OSHA's silica standard requires at minimum an N95 for silica exposure at action levels, with higher protection (APF 10 or higher) required above the PEL.

Contractor's license copy
Subcontractor agreement only

There is no difference for tax purposes
Employees have taxes withheld and employers pay payroll taxes; independent contractors are responsible for their own taxes (Correct answer)
Independent contractors must be licensed
Independent contractors receive benefits

Correct answer: Employees have taxes withheld and employers pay payroll taxes; independent contractors are responsible for their own taxes

Employers withhold income tax and pay FICA for employees, while independent contractors receive 1099s and pay self-employment taxes themselves—misclassification carries serious penalties.

Gloves only
Steel-toed boots only
Hard hat only
Safety glasses or face shield, hearing protection, and a dust respirator (Correct answer)

Angle grinding on masonry creates flying debris, loud noise, and silica dust, requiring eye/face protection, hearing protection, and respiratory protection.

5 working days
30 working days
