health care II

lesson 1:Facility Electrical Equipment Maintenance

QuestionAnswer
According to CMS requirements, “maintenance shall be performed in accordance with ? .” "Maintenance shall be performed in accordance with the equipment manufacturer's recommendations."
CMS allows health care facilities to develop Alternative Equipment Maintenance Programs that may increase or decrease ? depending on the requirements of the electrical system taken as a whole. CMS allows health care facilities to develop alternative equipment maintenance (AEM) programs that may increase or decrease the intervals between the manufacturer's recommended maintenance periods, depending on the requirements of the electrical system.
Alternative Equipment Maintenance Programs ? . AEM programs must be in writing and must detail not only the rationale for the program but must also provide past data justtifying the adoption of the AEM program. They should be published for maintenance personnel or contractors.
? may be defined as the periodic inspection, repair, and cleaning of connections, contacts, dirt and grime build up, and evidence of overheating and corrosion. Maintenance is defined as the periodic inspection of connections, contacts, dirt and grime build-up, and any evidence of overheating and corrosion.
During maintenance on an essential electrical system, which task is not required by NFPA 110? NFPA 110 doesn't require that maintenance must be scheduled with CMS. It does require that action be taken to prevent overheating, moving parts be must lubricated as per the manufacturer's specifications and connections must be tightened to specifications
NFPA 110 suggests that the essential electrical system be exercised, under load, ? . The system is to be exercised, under load, once a month and the test is to be initiated by and automatic transfer switch, simulating a power outage.
The regular operational testing of the essential electrical system is to be initiated by ? . The regular operational testing of the essential electrical system is to be initiated by an automatic transfer switch.
In the event the health care facility uses stored energy to provide for an element of an essential electrical system, ? provides guidance on the maintenance and operational testing of these systems. NFPA 111: standard on stored electrical Energy emergency and standby power systems chapter 8 provides guidance on the maintenance and operational testing of these systems as well.
Maintenance of which system is not included in NFPA 70B? Hydroelectric turbines . The NFPA 70B has chapters detailing the maintenance of photovoltaic systems, electrical vehicle charging stations, wind power systems and electrical disaster recovery.
? is neither a standard nor a code; therefore, it is not enforceable by an authority having jurisdiction. NFPA 70B. although not a standard or code, and thereore not enforceable by an authority having jurisdiction, when considering maintenance and testing, NFPA 70B is just as important to an Electrical Worker as NFPA 70 is when installing electrical systems.
The InterNational Electrical Testing Association produces four ANSI standards. Which is not a standard produced by NETA? bonding and grounding. NETA produces four ANSI standards: accepance testing, maintenance testing, commissioning specifications, and technician certification.
What should be considered when scheduling maintenance work after hours? Have arrangements been made for feeding the crew, are restroom facilities available , is there drinking water on site, does the job require special skills, equipment, test instruments or PPE
t/f Switchgear panel covers rarely need to be removed during maintenance. false.
When a scope of work has been drafted for a maintenance shutdown, it is important for all technicians involved to ? . does each worker know his or her role on the project?
t/f Maintenance testing is rarely documented as long as the system appears to be functioning correctly. false
What is the first step towards establishing an electrically safe work condition? Determine all possible sources of the electrical supply.
Under what conditions will OSHA allow work to be performed on energized conductors or equipment? OSHA allows work on energized conductors and equipment under two conditions. it is justified when exposed live parts are not deenergized for reasons of increased or additional hazards, or when it is infeasible to turn off the power
A ? demonstrates skills and knowledge about the construction and operation of electrical equipment and can perform work on or near energized equipment and has received safety training to identify and avoid all hazards involved in the work process. qualified person
Unqualified workers are not allowed to work within the ? approach boundary, but can work within the ? approach boundary after proper training and only when accompanied by a qualified worker. Unqualified workers are not allowed to work within the prohibited approach boundary, but can work within the limited approach boundary after proper training and only when accompanied by a qualified worker.
When is an energized electrical work permit required? An energized work permit is required when hot work is performed within the restricted approach boundary, and when energized equipment, conductors, or circuit parts are not exposed but an increased likelihood of injury from arc flash exposure exists
Before starting live work, the technician in charge shall review ? . Before starting each job, the employee in charge shall review hazards associated with the job, work procedures, special precautions, energy source controls, PPE requirements and other information relating to the energized work permit.
? should be consulted for abnormal hot spots, or any area showing overheating. infared thermographic scans taken before the scheduled maintenance session should be consulted for abnormal hot spots or any area showing overheating.
When checking terminations for proper torque, what is the best method to ensure that all terminations have been checked? terminations, fasteners and mounting bolts should be checked for proper torque, and then marked in some manner as having been checked
What should be considered when replacing fuses or circuit breakers during maintenance? should the replacement of fuses or circuit breakers be on the tasklist, be certain the new overcurrent protection device has appropriate rattings for both over-current as well as interrupting ratings consistent with the equipment and the system.
