Selected Answer: ionizing radiation guards Correct Answer: ionizing radiation guards Question 2 8 out of 8 points In arc welding operations, cables with splices within __________ shall not be used. Selected Answer: 10 feet (3 M) of the holder Correct Answer: 10 feet (3 M) of the holder Question 3 8 out of 8 points In what standard would you find a specific prohibition against modifying the end of a plug-in cord? Selected Answer: 1910.334 Correct Answer: 1910.334 Question 4 8 out of 8 points Whenever welding or cutting is performed in locations where other than a minor fire might develop, which of the following must be done as a precautionary measure? Selected Answer: Fire watchers should be stationed to observe the operation. Correct Answer: Fire watchers should be stationed to observe the operation. Question 5 0 out of 8 points A(n) __________ is a device designed to open and close a circuit by non-automatic means and to open the circuit automatically on a predetermined overcurrent without damage to itself when properly applied within its rating. Selected Answer: ground fault circuit interrupter Correct Answer: circuit breaker Question 6 12 out of 12 points What is a Class I, Division II location? Include an example in your explanation. Include the citation for the OSHA standard where you found the answer to the question. Your response should be at least 75 words in length. Selected Answer: Correct Answer: Response Feedback: A Class I, Division II location is a location where volatile flammable liquids and flammable gases are used and in such circumstances become hazardous in an accident during operating conditions. These locations have piping that have checks, meters, valves, or devices that prevent the introduction of flammable liquids and/or gases which is found in 1910 Subpart S.399 [None] Antonio, A good response. Here is the grading according to the rubric: Content, 7/7; Organization: 3/3, Writing Mechanics: 2/2; Total: 12/12 We need to understand these classifications and how they affect each area in which flammable or hazardous materials are stored. That is the only way to keep our employees safe. Question 7 12 out of 12 points What are the requirements for safe indoor storage of oxygen cylinders used in oxygen-fuel gas welding? Include the citation for the OSHA standard where you found the answer to the question. Your response should be at least 75 words in length. Selected Answer: Correct Oxygen cylinders should be stored away from combustible materials such as oil or grease. If they are stored in outdoor generator houses, they must be stored away from generators by a on combustible rated 1 hour wall. Oxygen cylinders must also be separated from combustible materials by at least 20 feet in accordance to 1910.253(b)(4) “Oxygen Storage”. [None] Answer: Response Feedback: Antonio, Another good response. Here is the grading according to the rubric: Content, 7/7; Organization: 3/3, Writing Mechanics: 2/2; Total: 12/12 This standard clearly needs to be followed at all times. There are some really good examples on the net concerning flammable gases being left in vehicles and having slow leaks. The result is an explosion when the employee enters the vehicle and introduces an ignition source. Question 8 12 out of 12 points List three uses for flexible cords that are not allowed by Subpart S. Include the citation(s) for the OSHA standard(s) where you found the answer to the question. Your response should be at least 75 words in length. Selected Answer: Subpart S CFR 1910.305(g)(1)(iv) lists about 6 regulations as to where flexible cords are not allowed. Flexible cords are not to be substituted for fixed wiring going through holes in the walls, ceilings, or floors. Flexible cords should not be attached to building surfaces, and finally cords cannot run through doorways, windows, or similar openings. Correct [None] Answer: Response Feedback: Antonio, Another good response. Here is the grading according to the rubric: Content, 7/7; Organization: 3/3, Writing Mechanics: 2/2; Total: 12/12 29CFR1910.305(g)(1)(iv) clearly states those examples that cannot be used with flexible cords. You cannot believe the number of times that I have found violations of this nature in buildings. This is also an issue on construction sites. Question 9 12 out of 12 points What is an abrasive wheel ring test? When must a ring test be conducted? Include the citation for the OSHA standard where you found the answer to the question. Your response should be at least 75 words in length. Selected Answer: Correct Answer: Response Feedback: An abrasive ring test is an inspection performed on wheels to check for damage. The wheels are mounted on a spindle to go no faster than the speed marked on the wheel. Wheels are tapped with an object such as a metal handle or wooden mallet, if the sound is cracked then the wheel must be discarded and not used. The test should be performed immediately before mounting according to 1910.215(d)(1). [None] Anotnio, Another good response. Here is the grading according to the rubric: Content, 7/7; Organization: 3/3, Writing Mechanics: 2/2; Total: 12/12 The "ring test" must be used before installing any wheels on the motor. This "ring test" has saved a lot of employees from injury because the wheel was bad but that could not be seen with the human eye. Question 10 12 out of 12 points For offhand grinding machines, what is the maximum permissible opening between the work rest and the abrasive wheel? Include the citation for the OSHA standard where you found the answer to the question. Your response should be at least 75 words in length. Selected Answer: Correct Answer: Response Feedback: To avoid injury or equipment damage, work rests should have no more than an eighth of an inch opening between the work rest and the abrasive wheel. Work rests should be secured tightly and no adjustments should be made when wheel is in motion. 1910.215(a)(4). [None] Antonio, Another good response. Here is the grading according to the rubric: Content, 7/7; Organization: 3/3, Writing Mechanics: 2/2; Total: 12/12 This requirement clearly keeps the employee safe. I have investigated an incident where an employee was grinding a file and it got pushed down between the rest and the wheel. Needless to say the employee's knuckles were pushed up against the wheel and were cut very badly. Of course this only occurred because the rest opening was greater than 1/8 inch.
