Hydraulic lifting platforms are often used in dangerous places. Therefore, special training is required for the staff. The staff has mastered a lot of techniques. However, due to the frequent operation of the hydraulic lifting platform, it is very boring. Therefore, the staff sometimes operates negligence and causes accidents. So we should master some operating techniques to avoid unnecessary accidents.
Hydraulic lifting platform safe operation skills
1. The staff is forbidden to leave the post and to wipe, lubricate or repair the hydraulic lifting platform during the work of the hydraulic lifting platform. When the work is completed, the staff should cut off the power and lock the control panel to leave the post and fill in the good post. recording.
2. When the mobile hydraulic lifting platform fails or fails to work properly, it shall immediately notify the maintenance personnel to repair it. If it is found to be dangerous or may cause a personal mechanical accident, it shall be immediately disabled, cut off the main power supply of the engine room, and report to the management department. It can be used after it is repaired and checked in detail.
3. The staff shall be responsible for supervising the distribution of the items transported by the hydraulic lifting platform on the countertop as evenly as possible to prevent partial loading and prohibiting overloaded operation. The hydraulic lifting platform is not allowed to carry and transport dangerous articles such as flammable and explosive materials, and it is forbidden to climb or shake people when they are raised.
4. Before the work, the staff shall shut down the active doors at the two ends of the fence and start the operation after it is locked. It is forbidden to work under the condition that the protective fence is open. When the hydraulic lifting platform travels, the emergency stop switch can be used to stop the hydraulic lifting platform in case of special circumstances. However, in normal operation, the use of the emergency stop switch is prohibited.
5. Before the daily work, the staff must carefully check whether the electrical system, hydraulic system and mechanical system of the hydraulic lifting platform are normal, and test the hydraulic lifting platform several times without loading and unloading to check whether there is any fault or abnormal phenomenon. It is important to note whether there is a significant abnormality in the accuracy of the landing station of the hydraulic lifting platform.
6, the use of units should arrange for someone to operate the lifting hydraulic lifting platform and work out the details of the lifting hydraulic lifting platform and safety precautions on their own units, and hang in a clear position, the operation staff must go through the statutory management training assessment, obtain qualifications for employment The license can be operated after the hydraulic lifting platform.
All in all, we must maintain a rigorous approach to the operation of the hydraulic lifting platform, the most professional technology, responsible for others responsible for their own.
Epichlorohydrin, 3-Chloro-1, 2 - epoxypropene, chloropropylene oxide ,ECH .
Molecular Formula: CH2OCHCH2Cl, C3H5OCl
Properties: It is a volatile, unstable colorless liquid with irritating odor similar to chloroform and ether. Molecular weight is 92.85, density, 1.1806g/cm3, boiling point, 116.11°C, freezing point, -57.2°C, refractive index (nd20), 1.4382, flash point (open cup), 40.6°C, and ignition point, 415°C. It is slightly soluble in water, miscible with many organic solvents, and able to generate azeotrope with a variety of organic liquids.
Main Applications:
Epichlorohydrin is an important organic industrial chemical and a chlorine-consuming product in fine chemicals, mainly for producing epoxy resin, synthetic glycerin, epichlorohydrin rubber, nitroglycerine explosives, glass fiber reinforced plastics, and electrical insulation products, which are widely used in the chemical industry, light industry, transportation, medicine, electronics and other fields. It also can be used as solvent for cellulose ester, resin, and cellulose ether, and the raw material of plasticizer, stabilizer, surfactant, and chloroprene rubber.
Toxicity and Protection: It is highly toxic, absorbed through the skin, and irritating to skin and mucous membranes. In higher concentrations, it has the function of narcotism. When poisoning occurs, there will be eye irritation, conjunctivitis, rhinitis, lacrimation, cough, fatigue, gastrointestinal disorders, nausea and other symptoms. Serious poisoning may lead to anesthesia or even lung, liver or kidney damages. Lethal concentration of human beings is 20ppm. Lethal dose of rat is 5090mg/kg. The maximum allowable concentration in air is 5ppm (18mg/m3). Production equipment needs to be closed, air, circulating, and the operator, wear protective equipment. In addition, due to intense auto polymerization, epichlorohydrin can not be heated in the fire in case of container burst. As for reaction as reagent, it is appropriate to be diluted with inert solvent and slowly added.
Packaging, Storage and Transport:
As ferric chloride or stannic chloride can promote auto polymerization, epichlorohydrin should be stored in dry, clean iron barrel, 200kg each, and kept in a cool, ventilated, and dry place, away from fire and heat. Store and transport in accordance with the provisions of flammable toxic substances.
