b Permitted category: Work here (green background, with a diameter in the middle 210mm white circle, black text inside the circle)

c Warning category: Stop high voltage danger (red edge on white background, black text, red arrow)

What are the safety aspects of electrical system work? What are the functions of signboards

Signboards are divided into categories according to their purpose. There are eight categories in four categories: warning category; allowed category; prompt category and prohibited category.

The purpose of the sign is to warn workers not to approach live parts of the equipment, to remind workers to take safety measures at the work site, and to indicate that it is prohibited to close and send power to a certain piece of equipment.

The hanging and removal of signs must be carried out in accordance with relevant regulations.

What are the safety signs for high voltage?

Prohibited signs include: "No closing, someone is working!", "No closing, someone is working on the line!". Permitted signs include: "Work here!" and "From now on!". Warning signs include: "Stop, high voltage is dangerous!", "No climbing, high voltage is dangerous!". The size of the above-mentioned signboards and the color of the background are strictly regulated by the state. If necessary, there should be corresponding warning signs, such as no driving, no passing, no watching fireworks, beware of electric shock, pay attention to falling objects, you must wear a safety helmet, protective gloves, goggles, etc.

What are the pictures of safety signs for electric power engineering construction? Do electrical safety signs have a grounding mark?

Nowadays, the Internet is accessible in all directions, and many things can be found by searching online. , the prices are comparable, you can also see the reviews of other buyers, it is open and transparent, the logistics is now fast, and the price/performance ratio is still very high. ——Huishun Traffic

What safety signs should be installed in low-voltage power distribution rooms?

Stop, high voltage is dangerous. It is forbidden to close the switch, someone is working. It is prohibited to close the switch or have someone working on the line.

"No climbing, dangerous due to high voltage. Work here.

Signs for entry and exit from here

Closing is prohibited, someone is working!

Once closed, power can be sent to the circuit breaker (switch) and isolating switch (knife switch) of the construction equipment for operation On the handle

What are the warning signs for power distribution rooms?

Non-duty electricians are prohibited from operating

High voltage is dangerous or be careful about electricity

What are the common electrical safety techniques

Ground wire has many applications Use soft bare copper wires, choose the working location, erect low-voltage lines on the same pole, and technical measures to ensure safety

1. During a power outage, when working on low-voltage live lines, but not less than 25mm2

⒋Hang signs and install barriers.

⒋Before going up the pole, you should distinguish the phases and hang the "No closing: disconnect switch"

⒉Inspect electricity, construction equipment and power can be sent to the work site as soon as it is closed. Or on the operating handles and neutral lines of switches and knife gates of construction equipment: when working on electrical equipment, work tickets, transfer and termination systems, and organizational measures to ensure safety must be filled in first. Long-sleeved clothes must be worn when working, and tools with insulated handles must be used. Tools: Work on electrical equipment should be carried out only after obtaining permission. Workers are not allowed to cross, and they must wear gloves and safety helmets, followed by conductor ends, metal rulers, brushes with metal objects, bristle bombs and other tools.

⒊Work supervision system.

⒊When low-voltage live conductors are not insulated, there is a sign indicating "someone is working", and organizational and technical measures to prevent accidental contact with live high-voltage parts to ensure safety.

1.

⒍The live part is only allowed to be located in front or on one side of the worker; the order of removing the grounding wire is reversed.

⒋Work interruption: When installing the grounding wire, you must first connect it to the grounding terminal, and stand on a dry insulating material during work: at the work site.

⒌The human body must not come into contact with two threads at the same time.

3. Its cross-section should meet the requirements of short-circuit current, and the distance from the high-voltage line should be checked first:

2. There must be one person at the work site to supervise the work of all workers.

⒉High:

⒈Work ticket system, it is strictly prohibited to use a knife: a qualified electroscope with the same voltage level must be used

⒊Install a ground wire, Maintenance without power outage

⒈Low-voltage live work should be monitored by dedicated personnel.

2. Work permit system

Price of electric power safety warning signs, what materials are commonly used for warning signs in power distribution rooms

There are clear regulations on safety work in the electrical industry Regulation. It stipulates the language expression, the color and size of the characters and base plates of various signboards. It also stipulates the safety signs that should be equipped in the power distribution room.
