When can you work on live electrical equipment?
When is it safe to work on live electrical equipment? It is never absolutely safe to work on live electrical equipment. There are few circumstances where it is necessary to work live, and this must only be done after it has been determined that it is unreasonable for the work to be done dead.
When working on live circuits the electrician should?
Get someone to watch you: stay in constant communication and ask them to pull you away from the circuit with a non-conductive tool (broomstick) if you stop talking or get shocked. Go slow, you have just reduced your margin for accidents to approximately zero. Use gloves 100% of the time. Cap off live wires immediately.
When should energized electrical work be considered?
An Energized Electrical Work Assessment must be completed for all work on or near exposed electrical conductors greater than 50 volts, with the exception of diagnotic testing as described above, where an electrically safe work condition cannot be established.
Under what conditions do employers authorize work on energized circuits and components of 50 volts or higher?
ANSWER: According to OSHA’s 29 CFR 1910.333(a)(1), working on live parts that operate above 50 volts is allowable ONLY when the employer “can demonstrate that de-energizing introduces additional or increased hazards or is infeasible due to equipment design or operational limitations.”
What prevents energizing circuits when others are near or working on them?
Overhead Lines Such protective measures, such as guarding, isolating or insulating, shall prevent the qualified person performing the work from contacting the lines with any part of their body or indirectly through conductive material, tools, or equipment.
What are the two main electrical hazards a qualified electrical worker looks out for?
OSHA defines qualified workers as those specially trained to work on live electrical equipment. Qualified workers must protect themselves against all electrical hazards including shock, arc flash, burns and explosions. Training is key.
What are examples of electrical hazards?
What are Examples of Electrical Hazards?
- Contact with live wires resulting in electric shock and burns,
- Fires due to faulty wiring,
- Exposed electrical parts,
- Ignition of fires or explosions due to electrical contact with potentially flammable or explosive materials,
- Inadequate wiring,
Which of the following is considered an electrical hazard?
Electrical hazards expose workers to the following: Burns: Three types; electrical, arc flash, or thermal contact. Electrocution: Electrocution is fatal; it means to kill with electricity. Shock: A response to electric current passing through the body.
Who needs electrical safety training?
NFPA 70E training should include not only “qualified persons” who work directly with electrical equipment, but also “unqualified persons,” such as maintenance or janitorial staff who work near a hazard. Outside contractors and others who may visit the facility should also be considered.
Who is electrical qualified person?
OSHA requires that only a “Qualified Person” may work on or around exposed energized equipment and defines that a “Qualified Person” as is “one who has received training in and has demonstrated skills and knowledge in the construction and operation of electric equipment and installations and the hazards involved.”
What makes an electrician qualified?
To qualify as an electrician, you need an industry-recognised Level 3 qualification, such as: Level 3 NVQ diploma in Electrotechnical Services (Electrical Maintenance) Level 3 NVQ diploma in Installing Electrotechnical Systems & Equipment (Buildings, Structure and the Environment)
Who is the most qualified person to conduct the JSA?
The most important person in JSA process is the Supervisor, who is in constant contact with employees and should be familiar with the hazards in their Department. Supervisors are in a better position to recognize and correct unsafe acts and conditions as they occur.
How often should a JSA be completed?
How often should you conduct a JHA/JSA? According to American Society of Safety Engineers President Thomas Cecich, some employers review them each year. And Dankert points out that they don’t last forever and should be reviewed every one or two years.
Is Swms same as JSA?
To summarise the difference between a JSA and SWMS, a SWMS is specific to the construction industry and is required for all high-risk construction work while a JSA is a one or two page form which outlines the hazards associated with a particular job or task.
Is a JSA required by OSHA?
OSHA requires a written certification that the hazard assessment has been performed. Use a job hazard analysis (JHA) or job safety analysis (JSA) approach that identifies potential physical, chemical, biological or other hazards for each work task.
How many job steps are typical in a JSA?
four steps
What are the 7 types of hazard?
The six main categories of hazards are:

- Ergonomic.
- Psychosocial.

What are the 4 methods of fall protection?
There are four generally accepted categories of fall protection: fall elimination, fall prevention, fall arrest and administrative controls.
What is the best fall protection control?
In order of best to worst, these solutions are: Hazard Elimination, Passive Fall Protection, Fall Restraint, Fall Arrest, and Administrative Controls.
- Hazard Elimination. The preferred solution to all fall hazards is elimination.
- Passive Fall Protection.
- Fall Restraint Systems.
- Fall Arrest Systems.
- Administrative Controls.
What is passive fall protection?
A “passive” fall protection system refers to a system that is non-dynamic, stationary, and does not move or adapt or change when in or out of use. They do not require the use of Personal Protective Equipment or active participation from the worker. Typical passive solutions include Guardrails or Netting Systems.

Are patient falls preventable?
No specific intervention can prevent all falls from occurring; therefore, it’s important to tailor falls prevention tactics to each patient’s risk profile. Identifying risk factors for each patient is key for recognizing those who may fall.
