Five safety precautions for crusher production line

In the design and manufacturing process of crusher equipment, many measures have been taken to avoid harm to health and safety. However, there are many potential hazards in the actual production process. In order to avoid these hazards, our manufacturer recommends that you carefully read and strictly abide by the recommendations in this technical article, and follow the basic safety operating regulations of the crusher and the country’s Relevant safety regulations, regular maintenance and safety training for relevant operators, hang eye-catching warning signs in hazardous areas in the crusher production line workshop, use appropriate protective equipment and tools during production operations, in addition, owners and management Personnel must perform their duties, formulate and abide by effective safety operating procedures and rules and regulations.
 Next, let’s talk about the safety precautions for the basic operation of the crusher. The following basic safety precautions are just a guide. The purpose is to make all personnel aware of the dangers and potential dangers surrounding the equipment and work area. During the actual use of the equipment, due to differences in operating conditions and uses, there may be hazards and potential hazards not covered by this safety precaution. All judgments and corrections must be made on the spot. The company’s technicians have summarized the following points to pay attention to when operating the crusher according to the scene:
1. Personal safety
Among all the factors of production, personal safety is the most important, so we put it first.
(1). Be familiar with all warning, attention and explanation signs in the production line, as well as all warning signs and instructions on the equipment and surrounding areas;
(2). Once an accident occurs, report to the superior immediately. If anyone is injured, call the emergency number as soon as possible to contact the local hospital doctor or medical staff for treatment;

(4) After drinking alcohol, taking sedatives or drugs that may reduce and affect your vigilance and judgment ability, it is absolutely not allowed to operate or work on the equipment;
(5). When performing fault inspections on the equipment, escalators, handrails and other safety protection devices should be used, and safety belts should be used if necessary;
(6). Always pay attention to the danger of hair and loose clothes being caught in moving parts or control parts;
(7) In accordance with the operating regulations, in an environment where flying debris, debris or dust may enter the eyes, goggles should be worn. To ensure safety, goggles should always be worn to protect the eyes;
(8). Wear gloves to protect your hands to prevent possible cuts, abrasions, burns or solvent erosion, etc.;
(9). According to the work needs of the operating environment, or in accordance with local or national regulations, safety shoes and helmets should be worn in the work area;
(10). Before entering the work area, avoid carrying objects that are easy to fall, such as mobile phones, bracelets, watches, rings, necklaces and other wearing parts;
(11). Wear protective earmuffs in areas with loud noises;
(12). When painting or contacting chemicals, solvents and other substances harmful to health, breathing equipment or gas masks should be worn. Remember, long-term exposure to silica dust may cause silicosis;
(13) Do not rely solely on brute force during work, but use lifting and handling equipment. When lifting heavy objects, use leg strength instead of waist strength;
(14). The person in charge of the site conducts personal safety training for all employees from time to time, always reminds employees of their safety awareness, and keeps training records for later corrections and rectifications.
 2. Work area safety
(1) When the equipment is in operation, it is absolutely forbidden to correct the position of the bulk material in the crushing cavity or remove it from it to avoid accidents;
(2). Keep the working area clean and free of debris, and avoid stones or other materials from accumulating on channels, platforms, ladders and under conveyors;
(3) Non-workers are not allowed to enter or stay in the work area;
(4). On the surface of the equipment touched by hands and feet, always keep it clean, dry and without oil or grease;
(5) In order to ensure the normal operation and safety of the equipment in the work area, the equipment shall be regularly overhauled and routinely inspected, and the hidden dangers of the equipment in the work area shall be found, and records shall be made;
(6). Keep handrails, guardrails, ladders and platforms clean, dry and free of oil or grease. Store unused parts and tools in designated fixed locations;
(7). Store the safety equipment in the designated location, and confirm that all personnel in the work area know its storage location and the correct method of use,
(8). Do not stand under heavy objects that are being hoisted and suspended. When lifting equipment, use safety hooks or hooks with safety locks, and use fences if necessary;
(9). Understand the load-bearing limit of the ground in and around the work area and the available clear space in order to use appropriate lifting equipment;
(10). There shall be no obstructive objects in and around the work area in the work area;
(11). Hang eye-catching warning signs in dangerous areas in the production line or workshop, and use appropriate protective equipment and tools during production operations.
 3. The safety of crusher equipment
When inspecting the crusher, the following steps must be followed:
(1). All inspection and maintenance work must be carried out by trained and qualified personnel, and the maintenance instructions of the equipment shall be followed;
(2). Before implementing any inspection or maintenance, the safety interlock system must be used to disconnect the power supply of the crusher. If the operation of auxiliary equipment (such as vibrating feeder, belt conveyor, etc.) is also checked or maintained;
(3). Before starting the crusher, the equipment must be fully inspected, including: whether the equipment fixed connecting bolts and springs are loosened, whether the roller skating system has the phenomenon of lack of oil leakage and failure, whether there are materials in the crushing cavity, and broken The wear of the machine liner, etc.;
(4). During the operation of the crusher, it is necessary to pay attention to uniform feeding to avoid excessive or non-crushed materials from entering the crushing cavity;
(5). Potential hazards are formed during the working process of the crusher, these auxiliary equipment must be turned off and the power supply must be disconnected;
(6). When the staff are on duty, carefully record the detailed problems encountered during overproduction, and do a good job of handover.
 4. Production line equipment safety
(1) When conditions permit, the equipment should not be installed in the open field. A rain-proof and sun-proof shed should be built for the equipment to improve the performance and service life of the equipment;
(2). Do not modify, smear or remove warning signs without authorization, and establish a corresponding equipment registration system;
(3) The movable equipment should be placed on a firm and flat ground, and all supports and fixing devices should be confirmed to be firmly in place. The equipment should be supported and fixed according to the steps recommended by the equipment manufacturer;
(4) Before transferring the equipment, check whether there are any loose parts to prevent it from falling during transportation and ensure the safe transportation of the equipment;
