Machine Guarding, Grinders and Portable Tools questions for the CSP

Question 1

A maintenance crew is evaluating a mobile ladder stand with locking casters. The stand's tallest work surface is 12 feet above the floor and its shortest base dimension is 2.5 feet. No outriggers or counterweights are fitted. Which action does the standard require before employees use it at that height?

1. AReplace the casters with fixed legs, since stands with wheels may not exceed 10 feet
2. BAdd outriggers, counterweights, or comparable means to prevent overturning, because the height exceeds four times the shortest base dimension
3. CNothing further, because the limit is six times the shortest base dimension
4. DNothing further, as long as the casters are locked while the employee is on the stand

Question 2

A maintenance shop supervisor finds a worker using an air nozzle to blow metal chips off a milling machine table. The shop's compressed air line is regulated to 50 p.s.i. at the nozzle. The worker wears safety glasses, and a small deflector shield is positioned near the nozzle. What should the supervisor require?

1. AReduce the air pressure at the nozzle to less than 30 p.s.i. and keep effective chip guarding and personal protective equipment in use
2. BNothing further, because safety glasses and a chip shield make 50 p.s.i. acceptable for cleaning
3. CReduce the air pressure at the nozzle to less than 50 p.s.i. and remove the chip shield so the air can reach the chips
4. DStop using compressed air for cleaning at any pressure, since the standard prohibits it entirely
