license?
A) Installing tempered glass in a storefront
B) Applying window film to existing glass

*Explanation: The CR-65 license authorizes installation of glass, window film,
weatherproofing, caulking, sealants, adhesives, and glass-holding members. Installing
structural steel components requires a different contractor classification (e.g., structural

Explanation: The ROC is responsible for regulating and licensing contractors in Arizona,
ensuring compliance with state laws, handling complaints, and protecting consumers. It
does not enforce federal codes or set international standards.
Question 3
What is the minimum safe distance for operating a scissor lift near an unprotected
edge?
A) 3 feet
B) 6 feet
C) 10 feet
D) 15 feet
Correct Answer: B
*Explanation: OSHA requires that scissor lifts maintain a minimum 6-foot distance from
unprotected edges unless fall protection (guardrails or personal fall arrest system) is in

remains relatively cool, resulting in a product that breaks into small granular pieces?
A) Annealed glass
B) Tempered glass
,C) Laminated glass
D) Insulated glass unit (IGU)
Correct Answer: B
Explanation: Tempered glass undergoes a heating and rapid cooling (quenching) process
that creates compressive stress on the surface. When broken, it shatters into small,
relatively harmless granular pieces.
Question 5
What is the maximum gap allowed between guardrail midrails and the working surface?
A) 19 inches
B) 21 inches
C) 25 inches

measured from the top rail. However, the maximum vertical gap from the working surface
to the midrail is 21 inches.
Question 6
