When using protective gloves, you must analyze the workpiece, equipment and operating conditions, and then choose the appropriate material made of gloves that are easy to operate in order to play a protective role. But for the work that needs to be fine-tuned. Wearing protective gloves is not easy to operate, especially for the use of drilling machines, milling machines and conveyors and have the danger of pinching and squeezing the parts of the operator, if the use of gloves, there is a risk of being entangled in the machinery or clamped. Therefore, personnel engaged in these operations, strictly prohibit the use of protective gloves.
The following types of protective gloves are commonly used on electric construction sites:
(1) labor protection gloves. With the function of protecting hands and arms, operators generally use these gloves when working.
(2) insulated gloves for electrified work. To choose the appropriate gloves according to the voltage, check the surface for cracks, sticky, brittle and other defects, such as abnormal prohibit the use.
(3) Acid and alkali resistant gloves. Mainly used for gloves worn in contact with acids and alkalis.
(4) rubber oil-resistant gloves. Mainly used for contact with mineral oil, vegetable oil and fat clusters of all kinds of soluble operations when wearing gloves.
(5) welder's gloves. Electricity, fire welding work when wearing protective gloves, should check the leather or canvas surface with or without stiffness, thin file, holes and other defects, such as defects, are not allowed to use. Gloves should have enough length, the wrist can not be exposed to the outside.
The following types of protective gloves are commonly used in food processing, chemical and medical industries:
(1) Latex gloves. Latex gloves are suitable for automotive manufacturing, battery manufacturing; fiberglass industry, aircraft assembly; aerospace field; environmental cleaning and cleaning. Latex gloves are abrasion and puncture resistant; resistant to acid and alkali, grease, fuel and many solvents, etc.
(2) Nitrile gloves. Mainly used in food processing, electronic components production, chemical and other factory protection, in hospitals, scientific research and other industries are also widely used. Nitrile gloves do not contain protein, no allergic reaction to human skin; non-toxic, harmless; strong and durable, high elasticity, high strength, good adhesion. It can effectively protect against organic solvents. Due to its excellent performance is gradually replacing the use of latex gloves. The helmet worn by workers on the construction site of electric power construction is mainly to protect the head from injury. It can protect the head from injury or reduce the degree of head injury in the following situations.
(1) when a flying or falling object strikes the head;
(2) when an operator falls from a height of 2m or more;
(3) when there is a possibility of electrocution to the head;
(4) when walking or working on a low part of the site and there is a possibility that the head may collide with a sharp, hard object.
Safety helmets should be worn in accordance with standards and used in accordance with regulations. If worn and used incorrectly, it will not play an adequate protective role. Generally, the following matters should be noted:
(1) Before wearing the helmet, you should adjust the adjusting band at the back of the cap according to your own head type to a suitable position, and then fasten the elastic band inside the cap securely. Cushion liner tightness adjusted by the band, the top of the person's head and the top of the cap in the body of the space of the vertical distance is generally between 25 to 50mm, at least not less than 32mm as good. This will ensure that when the impact is suffered, the cap body has enough space for buffering, usually also conducive to the ventilation between the head and the cap body.
(2) Do not wear the helmet askew, and do not wear the brim at the back of the head. Otherwise, it will reduce the protective effect of the helmet for impact.
(3) The lower tie of the helmet must be fastened under the jaw and fastened securely, with a moderate degree of elasticity. This is so that the helmet is not blown off by gusts of wind, or touched by other obstacles, or dislodged as a result of the head swinging back and forth.
(4) the top of the helmet body in addition to the cap liner installed inside the cap body, some also open a small hole ventilation. But do not use in order to breathe and casually re-open the hole. Because this will reduce the strength of the cap body.
(5) As the helmet in the process of use, will be gradually damaged. So we should regularly check, check there is no cracking, concave, cracks and wear and tear, etc., found anomalies to be replaced immediately, not allowed to continue to use. Any heavy impact, cracked helmet, regardless of the phenomenon of damage, should be scrapped.
(6) It is strictly prohibited to use the helmet which only has the jaw band connected with the cap shell, that is, the helmet without cushion layer inside the cap.
(7) Construction workers shall not take off the helmet and set it aside or use it as a cushion during on-site operations.
(8) As most of the helmets are made of high-density low-pressure polyethylene plastic, they have the nature of hardening and molting. So it is not easy to be exposed to the sun for a long time.
(9) the new helmet, first check whether the labor department allows the production of proof and product certification, and then see whether the damage, uneven thickness, cushioning layer and adjust the belt and elastic band is complete and effective. Those that do not meet the specified requirements are immediately exchanged.
(10) in the field of indoor work should also wear a helmet, especially in the indoor electrified operation, more carefully wear a helmet, because the helmet can not only prevent collision, but also can play a role in insulation.
(11) Usually use the helmet should be kept neat, can not touch the fire, do not arbitrarily paint, not allowed to sit as a stool to prevent loss. If lost or damaged, must be immediately reissued or replaced. No helmet is allowed to enter the construction site. V-type helmet W-type helmet On the construction site of electric power construction, there are a lot of high place operations and overlapping cross operations. In order to prevent the operator from falling at a certain height and position, the operator must wear a safety belt when ascending and working at a high place. The use and maintenance of safety belts have the following requirements:
(1)The role of safety belts must be emphasized in thought. Countless examples prove that the seat belt is a life-saving belt. But there are a few people feel the trouble of wearing a seat belt, walking up and down inconvenient, especially some small jobs, temporary jobs, that "there is a time to tie the seat belt are done". I do not know, the accident occurred in a moment, so the work at height must be required to fasten the seat belt according to regulations.
(2) before the use of safety belts should be checked before the deterioration of the rope, card ring whether there are cracks, card spring bounce is good.
(3) high place of work such as the safety belt is not fixed hanging place, should use the appropriate strength of the wire rope or take other methods. Prohibit the safety belt hanging in the mobile or with pointed tax pike angle or not solid objects.
(4) high hanging low use. Will hang the safety belt in the high place, the person below the work is called high hanging low use. This is a relatively safe and reasonable scientific method of hanging. It can make the actual impact distance is reduced when a fall occurs. The opposite is low hanging high use. That is, the safety belt hangs in the low place, and people work on it. This is a very unsafe method of hanging, because when the fall occurs, the actual impact of the distance will increase, the person and the rope are subjected to a larger impact load. So the safety belt must be high hanging low use, eliminate low hanging high use.
(5) the safety belt should be chained to a solid component or object, to prevent swinging or collision, the rope can not be used in knots, hooks should be hung on the connecting ring.
(6) The protective sleeve of the safety belt rope should be kept intact to prevent the rope from being worn out. If the protective sleeve is found to be damaged or detached, a new sleeve must be added before use.
(7) The safety belt is strictly prohibited unauthorized long use. If the use of 3m and above long rope must be added buffer, the components shall not be arbitrarily removed.
(8) safety belt in the use of each part to check whether intact. Safety belt after use, pay attention to maintenance and storage. The sewing part and the hook part of the seat belt should be checked frequently, and the twisted thread must be checked in detail for cracks and mutilations, etc.
(9) The safety belt should be properly stored when it is not in use, and should not be exposed to high temperature, open fire, strong acid, strong alkali or sharp objects, and should not be stored in a damp warehouse for safekeeping.
(10) safety belts should be sampling test after two years of use, frequent use should be frequently checked the appearance of the discovery of anomalies must be replaced immediately. Regular or sample test used safety belts, not allowed to continue to use.

Welders' overalls are generally white, and there is no restriction on the color of overalls for other types of work. Protective clothing has the following categories: (1) full-body protective overalls; (2) anti-virus overalls; (3) acid-resistant overalls; (4) fire-resistant overalls; (5) heat-insulating overalls; (6) air-cooled overalls; (7) water-cooled overalls; (8) anti-radiation overalls; (9) labor-protective raincoats; and (10) general overalls. RINBA DEFENDER respirator built-in airtight protective clothing GTA external airtight protective clothing RINBA PATROL respirator external airtight protective clothing on the construction site on the operator's protective clothing requirements are:
(1) the operator must wear overalls when working;
(2) operation of the rotating machinery, the cuffs must be tied;;
(3) the operation of the rotating machinery, the cuffs must be tightened. ;
(3) personnel engaged in special operations must wear special operational protective clothing;
(4) welder's overalls should be made of white canvas. The particles and debris of substances, sparks and heat flow, dazzling light and smoke can cause damage to the eyes. This makes it necessary to select and use protective eyewear according to the object of protection at the time. 4015 Chemical protection goggles SG-001/002/003 Goggles 3M1621 Chemical protection goggles (1) There are three kinds of anti-strike goggles:
① Hard glass sheet goggles; ② Gel-bonded glass glazing goggles (cracked when shattered by shocks and blows and not splashed); ③ Wire mesh goggles. They can prevent metal fragments or chips, sand dust, stone chips, concrete chips and other splashes on the eyes of the blow. Metal cutting operations, concrete chiseling operations, portable sander operations, etc. are suitable for wearing these plain goggles.
(2) anti-ultraviolet and glare with anti-ultraviolet goggles and radiation shield. Welding work with anti-radiation line mask should be made of non-conductive materials, observation windows, filters, protection sheet size match, no gaps. The color of the goggles is a mixture of colors, blue, green, gray is good.
(3) anti-hazardous liquid goggles simple mainly used to prevent acid, alkali and other liquids and other dangerous injections and chemicals caused by eye injury. General lenses made of ordinary glass, frame made of non-metallic corrosion-resistant materials.
(4) in the glass of the lens to add a certain amount of metal lead surface made of lead glass piece of goggles, mainly to prevent X-rays on the eye injury.
(5) anti-dust, smoke and a variety of slightly toxic or irritating weak toxic gases protective goggles must be sealed, cover the edge of no ventilation holes, and face contact is tight, the frame should be acid-resistant, alkali-resistant. There are more types of protective shoes, such as leather safety shoes, anti-static rubber-soled shoes, rubber-surfaced anti-smash safety shoes, insulated leather shoes, low-voltage insulated rubber shoes, acid- and alkali-resistant leather shoes, acid- and alkali-resistant rubber boots, acid- and alkali-resistant plastic molded boots, high-temperature protective shoes, puncture-resistant shoes, and welding protective shoes. They should be used according to the different choices of workplaces and contents. Power construction construction site on the commonly used insulated boots (shoes), welding protective shoes, acid and alkali resistant rubber boots and leather safety shoes.
The requirements for insulating shoes are:
(1) must be used in the specified voltage range;
(2) insulating shoes (boots) rubber part is not broken, and every six months for a preventive test;
(3) in the immersion of water, oil, acid, alkali and other conditions shall not be used as an auxiliary safety equipment.
