After the hot air blower comes into contact with chemical substances, targeted treatment measures should be taken according to the nature of the chemical substances. The following are the detailed treatment steps and precautions:
First, cut off the power supply and conduct a preliminary assessment
Cut off the power supply: Immediately stop the operation of the hot air blower and unplug it to prevent electric shock or secondary accidents.
Preliminary assessment: Identify the types of chemical substances in contact, evaluate their corrosiveness, flammability, toxicity and other properties, and take corresponding measures.
Second, chemical substance removal
External cleaning
Wear appropriate personal protective equipment, such as chemical-resistant gloves, goggles, gas masks, etc.
Gently wipe the surface of the hot air blower with a dry cloth or absorbent material to remove any remaining chemical substances. Avoid direct water rinsing, especially when the chemical substances may react violently with water.
For chemical substances that are insoluble in water and volatile, they can be allowed to evaporate naturally in a well-ventilated environment, but it is necessary to ensure that people stay away to prevent the inhalation of harmful gases.
Internal cleaning (if necessary) :
If chemical substances enter the interior of the hot air blower, the equipment must be disassembled by professionals.
Clean the internal parts with an appropriate solvent, but make sure the solvent is compatible with the chemical substances and does not cause more dangerous reactions. For instance, for oily chemical substances, organic solvents can be used for cleaning, but it is necessary to pay attention to the volatility and flammability of the solvents.
After cleaning, dry the internal parts with dry compressed air to ensure there is no residual moisture or chemical substances.
Third, equipment inspection and maintenance
Visual inspection: Check whether the casing of the hot air blower is corroded, deformed or damaged. If necessary, replace it.
Electrical system inspection: Check whether electrical components such as wires, plugs, and switches are damaged to ensure good insulation performance. If there is any damage, it needs to be repaired or replaced by a professional electrician.
Mechanical component inspection: Check whether mechanical components such as fans and motors are operating normally, and whether there is any jamming or abnormal noise. If necessary, lubricate or replace the damaged parts.
Fourth, security testing and resumption of use
Insulation test: Use a megohmmeter to test the insulation resistance of the hot air blower to ensure compliance with safety standards.
Functional test: In a safe environment, conduct no-load operation tests to observe whether the hot air blower is working properly and whether there is any abnormal heating, odor or noise.
Resumption of use: Only after testing and confirming safety can the normal use of the hot air blower be resumed.
Fifth, follow-up processing and record-keeping
Waste disposal: The waste generated during the cleaning process, such as fabrics contaminated with chemical substances and solvents, should be properly disposed of in accordance with relevant environmental protection regulations to prevent environmental pollution.
Accident record: Detailed records of the time, location, types of chemical substances, handling process and results of the accident, etc., to facilitate subsequent analysis and improvement.
