Question: When Working From A Scaffold Workers Should Keep A Minimum Distance Of?

How far away should you live from a transformer?

200 meters are a good safe distance, which usually ensures values corresponding to the population average.

Depending on the loads served by each line we can record normal levels even 50 meters or less from the cables..

What is the maximum distance the front edge of most scaffolding can be from face of work?

14 inchesExcept as provided in paragraphs (b)(3) (i) and (ii) of this section, the front edge of all platforms shall not be more than 14 inches (36 cm) from the face of the work, unless guardrail systems are erected along the front edge and/or personal fall arrest systems are used in accordance with paragraph (g) of this …

How close can you build next to power lines?

All structures must be located a safe distance from power lines. The distance can range anywhere from 15 to 75 feet, depending on the voltage. Any home or mobile home built or located within this minimum distance will not be connected for service. The owner will have to, at his or her expense, relocate the structure.

Is living near a transformer dangerous?

Transformer substations located close to the living areas could induce high long-term exposures to extremely low frequency magnetic fields of nearby inhabitants. Some of the researches have shown increased risk to childhood leukemia associated with the long term exposure to the elevated levels of magnetic fields.

What is a scaffolding standard?

Basic scaffolding The key elements of the scaffolding are the standard, ledger and transoms. The standards, also called uprights, are the vertical tubes that transfer the entire weight of the structure to the ground where they rest on a square base plate to spread the load.

What is the maximum load for a scaffold?

875 poundsThe type of scaffolding being used is rated as light-duty, or 25 pounds per square foot. Multiply 35 square feet by 25 pounds per square foot and the scaffolding can be loaded with no more than 875 pounds.

What is the minimum safe distance to be maintained from the overhead power lines?

50 feetMinimum clearance distance (feet) *According to 1926.1409, for power lines over 350 to 1,000 kV, the minimum distance is presumed to be 50 feet. Over 1,000 kV, the utility/owner or a registered engineer must establish it.

What is OSHA Standard for scaffold?

The space must not exceed 9½ inches (24.1 cm) when side brackets or odd-shaped structures result in a wider opening between the platform and the uprights. The standard requires employers to protect each employee on a scaffold more than 10 feet (3.1 m) above a lower level from falling to that lower level.

What is the minimum distance workers must maintain between conductive material and overhead power lines up to 50 kV?

The OSHA requirements limit crane operations to a minimum clearance of 10 feet for lines rated at 50 kilovolts (kV) or less and for lines rated over 50 kV use the following formula: In order to use the formula, a contractor must know the exact voltage of a power line to calculate line clearance distance.

Do power lines give off radiation?

except for the huge power lines directly behind it. … Power lines produce low-to mid-frequency magnetic fields (EMFs). These types of EMFs are in the non-ionizing radiation part of the electromagnetic spectrum, and are not known to damage DNA or cells directly, according to the National Cancer Institute.

What are some safety precautions for scaffolding?

Here are some of the best ways to observe proper safety precautions on the job and minimize the risk of scaffolding injuries.Prepare properly. … Ensure adequate training. … Securing the scaffold. … Don’t forget guardrails. … Regular maintenance and inspection. … Use personal protective equipment (PPE)

What is the distance between two electric pole?

They are typically spaced about 125 ft (38 m) apart in urban areas, or about 300 ft (91 m) in rural areas, but distances vary widely based on terrain. Joint-use poles are usually owned by one utility, which leases space on it for other cables.

How high can Scaffolding go?

Scaffold tower can be erected in all shapes and sizes. The standard dimensions are 5 foot and 7 foot long. Reaching 5 foot high all the way up to 30 feet tall.

How close does a scaffold platform need to be to the face of the work wall or building for general construction work?

When the front end of all platforms are less than 14 inches (36 centimeters) from the face of the work; 1926.451(b)(3) When outrigger scaffolds are 3 inches (8 centimeters) or less from the front edge; 1926.451(b)(3)(l) When employees are plastering and lathing 18 inches (46 centimeters) or less from the front edge.

What is a safe distance from power lines?

700 feetThe strongest magnetic fields are usually emitted from high voltage transmission lines — the power lines on the big, tall metal towers. To be sure that you are reducing the exposure levels to 0.5 milligauss (mG) or less, a safety distance of 700 feet may be needed. It could be much less, but sometimes more.

Is it safe to walk under power lines?

Do not go near downed power lines! If you are near lines which have come down, do NOT walk away! … Because the voltage decreases in an outward direction from where the wire contacts the ground, it means the voltage can be higher at one foot, and lower at your other foot if they are separated (by walking).

What height is fall protection on scaffolds required?

10 foot heightEmployers and employees should be familiar with seven key provisions of the revised scaffolding standard: The standard requires fall protection at a 10 foot height above a lower level for employees.

What is the safe distance from 11kV power lines?

1.2 metresAs per the Indian Electricity Act, buildings should maintain a horizontal distance of 1.2 metres from 11kV lines and 4 metres from 66kV lines.

Is safe distance from 400 kV line during the hot line maintenance?

For the 400 kV, 500 MW line under consideration, the flux density of 1.265 mg is reached when x = 77m; this implies that the safe clearance distance is 77m from the line centre on the either side. Thus, the overall safe clearance distance is 154m.
