1. What are the safety requirements for workers in fireworks production?
New workers must receive safety education and technical training when they enter the factory and change jobs, and they can only take up their posts after obtaining the operation certificate. It is forbidden to wear hard soles, spikes and flammable fiber clothing, and buttons, hairpins, knives and scissors and chains of strip steel products are not allowed to enter dangerous production areas. Personnel engaged in dust operations should have regular health checks. Persons with occupational contraindications shall not be arranged to engage in taboo operations, and persons under the age of 18 and disabled persons shall not be arranged to engage in pharmaceutical ingredients, building drugs and other processes. Personnel under the age of 16 shall not be arranged to engage in any production. It is forbidden to go to work after drinking. When working, you are not allowed to leave your post, and you are not allowed to wear medicine dust's work clothes and enter other workshops.
2, fireworks production should be equipped with what safety protection articles?
The factory should be equipped with protective articles that meet the requirements according to the nature and working conditions of the work, and implement the inspection and use system. Operators engaged in high-dust processes such as pharmacy, charge and pharmacy shall meet the following requirements: (GB 2626-81+0); Wear tight-fitting long-sleeved trousers, overalls, drag hats and cloth socks to minimize the exposed parts of the body, and the clothes are simple and easy to take off; Protective articles must be made of antistatic materials; When doing other jobs, you can't wear special work clothes used to prepare dangerous drugs such as chlorate.
3. Why can't ordinary plastic or rubber tools be used to make fireworks?
Ordinary plastics and rubber tend to accumulate static electricity when rubbing. When the static voltage accumulates to a certain range, it is easy to break through the air and discharge to another object, resulting in discharge sparks. Fireworks and firecrackers are easy to burn or explode when stimulated by electrostatic powder. In production, many enterprises like to use plastic and rubber tools. Both plastics and rubber are prone to generate static electricity after rubbing, but the conductivity of plastics and rubber is poor, and the generated static electricity is easy to accumulate, forming a high electrostatic voltage and easily generating discharge sparks. For example, some technicians like to mix drugs on plastic sheets, which is very dangerous. When the plastic sheet rubs against the drug, it will generate a high electrostatic voltage, which may discharge at any time and ignite the drug. Generally, it can be mixed with kraft paper, because kraft paper is not easy to generate electrostatic accumulation. So neither plastic nor rubber can be used as production tools for fireworks. Conductive plastics and conductive rubber made by special processing have conductivity and are not easy to accumulate static electricity, so they can be used as tools. For example, conductive rubber can be put on the medicine table to reduce the impact on the medicine; Liangzi frame is made of conductive plastic, which is convenient for storing Liangzi, etc.
4. Why can't employees of fireworks enterprises wear chemical fiber clothes to work?
Because the human body is also easy to accumulate static electricity, especially when wearing chemical fiber clothes, the human body will keep rubbing against the clothes, resulting in extremely high static electricity accumulation. When people with high electrostatic voltage come into contact with fireworks and firecrackers, it is easy to produce discharge sparks and cause accidents. In addition, chemical fiber clothes are easy to burn in case of fire and stick to human skin, causing great harm, so employees are forbidden to wear chemical fiber clothes to work.
1, how to pay attention to the preparation stage of raw materials in the manufacture of fireworks and firecrackers?
The raw materials used in the manufacture of fireworks and firecrackers must meet the quality standards of fireworks and firecrackers, and have a product certificate. It can only be used after testing and identification. In the process of preparation and use, substances that increase drug sensitivity shall not be mixed. If the following substances are mixed into fireworks and firecrackers, it will increase the sensitivity of drugs, and special attention should be paid to the production:
(1) Prohibited (or partially prohibited) raw materials such as potassium chlorate and pure magnesium powder;
(2) Hard particles such as sand and iron slag;
(3) moisture;
(4) acidic substances.
In addition, it should be noted that raw materials with a delivery date of more than one year can only be used after re-inspection. Some raw materials will deteriorate if they are left for too long, which will affect the quality and even the safety when they are made into fireworks and firecrackers. If the unsealed aluminum powder is left for a long time, it will be oxidized into alumina in large quantities, thus greatly reducing its performance; Sulfur powder will also be oxidized into sulfur oxide after long-term storage, and sulfur oxide will turn into acid when it meets water, which will increase the sensitivity of drugs when it is made into fireworks and firecrackers.
2. How to pay attention to safety in the crushing and screening of fireworks drugs in the manufacturing process?
Crushing should be carried out in a separate workshop. Mechanical impurities should be screened out before and after crushing. Tools that are easy to generate sparks such as iron and tools that are easy to generate static electricity such as polyamide fibers and plastics should not be used in screening. Tools such as wood, copper and aluminum can be used. When crushing inflammable and explosive articles, it must be carried out under the isolation protection of a safety protective wall. Generally, the raw materials used in black powder can be crushed by a single material, but charcoal and sulfur should be mixed and crushed as much as possible to make the drugs mixed evenly and safely. The raw materials used in fireworks can only be crushed separately by extension. When crushing highly sensitive materials by special plane and machinery, the following matters should be noted:
(1) Check the equipment before crushing and clean the dust carefully;
(2) It must be operated remotely, and it is forbidden to start the machine without leaving the computer room;
(3) When feeding and discharging materials, the machine must be stopped and powered off;
(4) When feeding and discharging materials, stop for 10 minute, and then carry out heat dissipation;
(5) Pay attention to ventilation and heat dissipation to prevent the dust concentration in the air from exceeding the standard.
When wet grinding is used, it is forbidden to overflow the foam of the material. After the crushed materials are packaged, they should be labeled with names immediately.

Multi-ball milling mixed black powder should be carried out in a separate workshop, operated remotely and equipped with explosion-proof facilities. The preparation of highly sensitive drugs such as chlorate in bud must have special workshops and tools, and protective facilities. If workshop tools need to be used for other purposes, they should be cleaned again before use.
