ITMC Safety Compliance & Technical Documentation 2 — Questions and Answers
Question 1: A maintenance technician is about to service a pneumatic system. What is the correct order of energy isolation steps under OSHA's Lockout/Tagout standard?
- Notify affected employees, shut down equipment, isolate energy, release/restrain stored energy, apply lockout devices (Correct answer)
- Apply lockout devices, shut down equipment, notify affected employees, isolate energy, release stored energy
- Isolate energy, shut down equipment, apply lockout devices, notify affected employees, release stored energy
- Release stored energy, apply lockout devices, shut down equipment, isolate energy, notify affected employees
Correct answer: Notify affected employees, shut down equipment, isolate energy, release/restrain stored energy, apply lockout devices
OSHA 29 CFR 1910.147 requires notification, shutdown, isolation, stored energy release, and then lockout device application in that sequence.
Question 2: Which document type provides step-by-step procedures for safely performing a specific maintenance task on industrial equipment?
- Material Safety Data Sheet (MSDS)
- Standard Operating Procedure (SOP) (Correct answer)
- Bill of Materials (BOM)
- Failure Mode and Effects Analysis (FMEA)
Correct answer: Standard Operating Procedure (SOP)
A Standard Operating Procedure (SOP) provides detailed, step-by-step instructions for performing tasks safely and consistently.
Question 3: Under NFPA 70E, what is the purpose of an Energized Electrical Work Permit?
- To authorize overtime pay for hazardous electrical work
- To document justification and safety measures when working on energized electrical equipment (Correct answer)
- To certify that a technician is licensed for high-voltage work
- To record the results of insulation resistance testing
Correct answer: To document justification and safety measures when working on energized electrical equipment
An Energized Electrical Work Permit documents why de-energizing is infeasible and ensures proper PPE and safety measures are in place.
Question 4: A Safety Data Sheet (SDS) Section 8 provides information primarily about:
- First aid measures and emergency response
- Exposure controls and personal protective equipment requirements (Correct answer)
- Physical and chemical properties of the substance
- Accidental release measures and spill cleanup
Correct answer: Exposure controls and personal protective equipment requirements
SDS Section 8 (Exposure Controls/Personal Protection) details occupational exposure limits and required PPE for handling the chemical.
Question 5: When a maintenance technician discovers an undocumented modification to a machine's electrical schematic, what is the most appropriate immediate action?
- Continue working and document the modification after completing the task
- Stop work, tag the machine out of service, and report the discrepancy to supervision (Correct answer)
- Update the schematic yourself to reflect the modification and proceed
- Ignore the modification if the machine appears to function correctly
Correct answer: Stop work, tag the machine out of service, and report the discrepancy to supervision
Undocumented modifications create unknown hazards; stopping work and reporting ensures safety and triggers proper documentation review.
Question 6: Which OSHA standard specifically governs the control of hazardous energy (lockout/tagout) for general industry?
- 29 CFR 1910.132
- 29 CFR 1910.147 (Correct answer)
- 29 CFR 1910.303
- 29 CFR 1926.417
Correct answer: 29 CFR 1910.147
29 CFR 1910.147 is OSHA's Control of Hazardous Energy standard, commonly known as the Lockout/Tagout (LOTO) standard.
Question 7: In technical documentation, a 'redline' drawing refers to:
- A drawing printed on red paper for hazardous area identification
- A drawing marked up by hand to show actual as-built conditions versus the original design (Correct answer)
- A drawing that indicates fire suppression system layouts
- A drawing flagged for immediate disposal due to obsolescence
Correct answer: A drawing marked up by hand to show actual as-built conditions versus the original design
A redline drawing shows handwritten or marked corrections reflecting actual field conditions that differ from the original design documents.
