20 cards
- Who leads the job briefing, and when?
- The employee in charge, with the employees involved, before they start each job.
- What five subjects must a job briefing cover at least?
- Hazards of the job, work procedures, special precautions, energy-source controls and PPE requirements.
- If the day's work is repetitive and similar, how many briefings are needed?
- At least one, before the start of the first job of each day or shift.
- When must extra job briefings be held during the work?
- When significant changes that might affect worker safety occur.
- When is a more extensive briefing required?
- When the work is complicated or particularly hazardous, or the worker cannot be expected to recognize and avoid the hazards.
- Does an employee working alone need a job briefing?
- No, but the tasks must be planned as if a briefing were required.
- What information must the employer give the employee in charge before a job?
- All available information on existing conditions, such as nominal voltages and the condition of poles.
- What controls must an aerial lift for live-line barehand work have?
- Dual controls: upper ones within easy reach of the worker in the bucket and lower ones near the boom base that can override.
- When may the ground-level lift controls be operated with a worker in the lift?
- Only in case of emergency.
- What must workers check before raising an aerial lift into the work position?
- That all controls, ground level and bucket, are in proper working condition.
- How is the daily boom-current test done for barehand work?
- The bucket touches an energized source of the working voltage for at least 3 minutes; leakage may not exceed 1 microampere per kilovolt.
- What fall protection must a worker in an aerial lift use?
- A travel restraint system or a personal fall arrest system.
- What is an enclosed space under 1910.269?
- A space such as a manhole, vault, tunnel or shaft with limited entry and exit, built for periodic entry and normally free of hazardous air.
- What must entrants and attendants of an enclosed space be trained in?
- The hazards of enclosed-space entry, entry procedures and rescue procedures.
- What must be checked before removing a manhole cover?
- Pressure or temperature differences and whether the space might hold a hazardous atmosphere.
- What must protect the opening once a cover is removed?
- A railing, temporary cover or other barrier, set up promptly.
- Which air test comes first before entering an enclosed space?
- Oxygen deficiency, with a direct-reading meter; flammable gases are tested after that.
- What accuracy must enclosed-space test instruments keep?
- They must stay calibrated, with a minimum accuracy of plus or minus 10 percent.
- In OSHA's electric power glossary, what is an attendant?
- An employee assigned to stay just outside the entrance of an enclosed space to help those inside as needed.
- What is step potential?
- The voltage between the feet of a person standing near an energized grounded object.
