-The thermal instrument mentioned in TCVN 5699-2-45 (IEC 60335-2-45).

Portable power instruments are designed to be used on transportation in addition to compliance with regulations of this standard, and there must be additional requirements of the authority with the authority on the safety of the employer when used.

1.2. Apply objects

This standard applies to:

1.2.1. Organizations, individuals produce, import, circulate, and use hand-in-hand electric instruments (later called the manufacturer, the importer, the seller, and the use of the hand-in-hand device).

1.2.2. State administration agencies and organizations, other individuals are involved.

1.3. Explain the word

In this Regulation, the use of the terms, definitions of the National Standard TCVN 7996-1:2009 (IEC 60745-1:2006) mobile phone instruments powered by engine-Safety-General Demand and TCVN 7996-2 (IEC 60745-2).

2. Technical Regulations

2.1. The object-based electromechanical instruments and the above range must ensure the requirements for safe technical specifications for motor-powered mobile electric instruments at TCVN 7996-1: 2009 (IEC 60745-1: 2006).

2.2. For each type of special hand-hand power, in addition to having to meet the general requirements for safe engineering techniques for mobile phone instruments, the above engine must meet the specific requirements of safe engineering for each type of electrical device. (if any) at TCVN 7996 Part 2 (IEC 60745-2).

2.3. In the case of the TCVN speaking there is a change, the addition is made in accordance with the latest regulations.

3. Regulation of labor safety management during production, import, circulation, and use of hand-in-hand power instruments.

3.1. The regulation ensures safety of hand-in-hand power instruments in manufacturing and imports prior to the introduction of the market.

The manufacturer, importing the handheld electric instrument must make the requirements for quality management as follows:

3.1.1. Applying the quality management system to ensure the quality of the hand-held power instruments, imported in accordance with the standard published standard.

3.1.2. Apply the applicable rules.

The manufacturer, the importer self-publishes the basic properties, the warning information, the standard number applied on hand-in-hand power instruments or by one of the following forms:

-On the packaging tool.

-On the label of the instrument;

-In the document with the instruments.

3.2. Safety assurance regulations for hand-in-market power in the market

3.2.1. Compliance with the corresponding technical standards in the process of hand-holding electrical instruments;

3.2.2. Self-imposed quality control measures in hand-in-hand traffic.

3.3. The regulation ensures safety for hand-in-hand power instruments in use.

3.3.1. Preserve and transport It must be preserved in the dry place and under the terms of the preservation of the hand-in-hand tooling. The place of the building, holding the right hand device, has to be priced, the scaffold to put the machine. A stack of hand-held power tools in a state of no package. When transporting a portable power device, it takes notice of the protection measures to avoid damaging the instruments.

3.3.2. Prepare a handheld device before you work. Each time the hand-held electric device for the user, the hand-to-hand phone user with the user must check the following items:

-Check the compound and the certainty of the grafts, attach, connect the parts of the portable power device.

-Review outside of the apparatus of the machine (source test, wire protection, plug, insulation of the shell, handles, broom lid, etc.).

-Check the circuit.

-No, no, no.

-With the ER I have to check the entire circuit to protect the machine. Unallocated and entering the use of portable power instruments found that although only minor damage, no safety standards or hand instruments were too limited to periodic testing.

3.3.3. Make sure that it's safe to run a handheld device. Only those who have been trained in electrical safety and use of handheld electric instruments, are granted a new safety card to be used. Only hand-armed instruments meet the regulations of this standard. Every handheld device has its own notebook. The person responsible for preserving and repairing the instrument must record the results of periodic examination, maintenance, and repair of the instrument. Keep the workplace neat and well-illuminated while using hand-holding power tools. Not to operate portable electrical instruments in a flammable, explosive environment (an environment with fluid, a flammable gas or an environment containing substances that can damage the details of the device's electrical structure).

In the environment containing drip water, or outdoors during the rain, fog is not operated without a water-proof, anti-water-proof instrument. Not to let the children and the non-remission close to the operation of the portable power device.

3.3.4. Make sure to ensure the safety of electricity. The plug of the portable power device must match the socket. Do not edit the plug in any way. Do not use any plug-in-link plug for the land-connected portable power device. When operating with a Class II handset must use the additional means of personal protection (insulated gloves, insulation, insulation mat, etc.). Do not allow the body to contact the surfaces that have joined the ground. Not using the source wire. Do not use the source wire to carry, drag or pull the plug of the portable power device. Keep the source wire away from the source of heat, oil, sharp edges or moving parts. When operating a portable power device outside the sky, it must be used to use an open source line suitable for outdoor use. If it is required to operate a portable electrical device in the moist area, use the (RCD) protection device to protect the source. It has to be noted to protect the electric cables that power the electric power to avoid being exposed to insulation, avoiding ointage or exposure to hot objects. The resumption of electrical appliances for portable power instruments (such as transmers, variable-frequency devices ...) with the grid and removing them from the grid must be responsible for the person with a charge of charge. A periodic trial for portable power instruments and accompanying device parts (transmable, transmusing devices, protective power-cutting equipment, source wires ...) at least once every six months. Recurring trials include:

-Look outside.

-Electronically Charged electronically electrically electrically electrically electrically charged, electrode becomes less than 2MΩ.

-Check the pulse.

Using a suitable personal protection vehicle when operating handheld devices such as anti-dust masks, anti-skaters, hard hats, auditory protection, eye protection glasses. Pay attention to unintentional handset. Make sure that the cutting mechanism is in the cutting position before linking to the power source for use. Make sure all the keys or repair tools have been removed from the handheld device before allowing it to work. Not too far from using a handheld device. Keeping people in the balance position at all times. If the device is equipped to connect with the vacuum and dust-gathering mechanism, ensure that they are connected and used correctly. With hand-armed instruments with a mass of more than 10kg, it has to be equipped with a mechanism to lift, hang tools when working. No active hand-wielding power is not working. Use the right hand-hand tool for every single job. Do not use portable power tools if the closed mechanism does not turn on and off the source. Cut off the power source before making adjustments, replace accessories, suspend work or store hand-wielding power. Take away the hand-hand power of the children's reach, not to have the untrained people safe with the instruments of hand-carrying equipment. Using only handheld devices, accessories, and details of the instrument for the work that is consistent with the functionality of the instrument and follow the instructions of the manufacturer, taking into account the work conditions and work required. When using a handheld electric device, it has to be noted for both the requirements outlined in the instructions to use the instrument, to keep the instrument carefully, not to be able to be struck, overloaded or affected by dirt, grease, not letting the water drip, rainwater or other liquid. Shooting at the equipment does not protect anti-moisture.

3.3.6. Repair and maintenance Users of hand-controlled electric instruments have to regularly check, maintenance, and statistical work done.
