CMS Safety Standards & Regulations 3 — Questions and Answers
Question 1: A machine guarding inspection reveals that a fixed barrier guard has a gap of 1 inch at a distance of 3 inches from the nearest point of operation. According to OSHA Table O-10, is this guard compliant?
- Yes, because the gap is less than 6 inches
- No, because any gap within 3.5 inches requires zero opening (Correct answer)
- Yes, any gap under 2 inches is always acceptable
- No, fixed guards are prohibited within 6 inches of point of operation
Correct answer: No, because any gap within 3.5 inches requires zero opening
OSHA Table O-10 specifies that at distances up to 3.5 inches from the point of operation, the maximum allowable opening is 1/4 inch, so a 1-inch gap is non-compliant.
Question 2: Under EPA's Risk Management Program (RMP) Rule (40 CFR Part 68), what triggers a Program 3 classification for a covered process?
- Any use of a regulated substance regardless of quantity
- The process is in NAICS codes subject to OSHA PSM and is not eligible for Program 1 (Correct answer)
- Annual emissions exceed the facility's Title V permit limits
- The facility employs more than 100 workers
Correct answer: The process is in NAICS codes subject to OSHA PSM and is not eligible for Program 1
Program 3 applies to processes in specified NAICS codes that are also subject to OSHA PSM and do not qualify for the less stringent Program 1 or 2.
Question 3: Which ANSI standard governs the safety requirements for industrial robots and robot systems in manufacturing?
- ANSI B11.0
- ANSI/RIA R15.06 (Correct answer)
- ANSI Z49.1
- ANSI Z87.1
Correct answer: ANSI/RIA R15.06
ANSI/RIA R15.06 is the American National Standard for Industrial Robots and Robot Systems – Safety Requirements.
Question 4: When must a Safety Data Sheet (SDS) be updated under OSHA's Hazard Communication Standard (29 CFR 1910.1200)?
- Every calendar year regardless of changes
- Within 3 months of learning of significant new hazard information (Correct answer)
- Only when the chemical formula is altered
- When requested by any employee at the facility
Correct answer: Within 3 months of learning of significant new hazard information
OSHA's HazCom standard requires SDS updates within three months of a manufacturer or importer becoming aware of significant new hazard information.
Question 5: In confined space entry operations, what is the role of the 'attendant' as defined by OSHA 29 CFR 1910.146?
- Enters the space to monitor air quality
- Remains outside the permit space and monitors entrants and conditions (Correct answer)
- Signs and dates the entry permit
- Provides first aid inside the space
Correct answer: Remains outside the permit space and monitors entrants and conditions
The attendant stays outside the permit-required confined space, monitors conditions and entrants, and initiates rescue if needed.
Question 6: What OSHA regulation establishes requirements for the control of hazardous energy during service and maintenance of machinery and equipment?
- 29 CFR 1910.212
- 29 CFR 1910.147 (Correct answer)
- 29 CFR 1910.303
- 29 CFR 1910.95
Correct answer: 29 CFR 1910.147
29 CFR 1910.147, the Control of Hazardous Energy (Lockout/Tagout) standard, governs procedures for deenergizing equipment during servicing.
Question 7: A facility's incident investigation reveals a 'near miss' event. Under best practice safety management systems, how should near misses be treated?
- Ignored unless an injury actually occurred
- Reported and investigated with the same rigor as actual incidents (Correct answer)
- Reported only if equipment was damaged
- Logged but not formally investigated to save time
Correct answer: Reported and investigated with the same rigor as actual incidents
Best practice SMS treat near misses as leading indicators and investigate them with the same rigor as actual incidents to prevent future harm.
