Safe installation

During the installation of electronic equipment, as well as tinning and soldering of mounting conductors and terminals of radioelements, measures should be taken to protect workers from burns, electric shock and poisoning.

Burns, poisoning, and especially electric shock can be of a different nature and varying degrees of severity of the consequences they cause: from short-term pain to irreversible changes in the body of the injured person, including even death.

Therefore, when installing P3A, it is necessary to strictly and rigorously observe the following rules for the safe performance of assembly work.

1. Perform work on serviceable equipment, using serviceable tools and devices, and use them only for their intended purpose. The soldering iron rod should not wobble, its handle should not have cracks, the cord should not have insulation faults.

2. Electrical wires supplying power to the workplace must be reliably insulated and protected from mechanical damage. The supply voltage of the local lighting, the electric soldering iron and the tin-bath should be no more than 36 V, the power supply of the insulation firing devices - 6 V. During the breaks between soldering, the soldering iron should be held on a metal or fire-resistant stand.

3. The soldered wire must be held with tweezers. Apply a thin layer of flux to avoid splashing during brazing. Remove excess solder from the soldering iron rod with a specially designed napkin, and do not shake off excess solder from the tip.

4. Using the side cutters, cut off the wire away from you. Make sure that the flying particles do not fall into the surrounding.

5. Work with fiberglass-insulated wires wearing cotton gloves.

6. Places where work is carried out with hazardous substances (fluxes, solders, glass tape, fluoroplastic, compounds, etc.) must be equipped with local exhaust devices, and all soldering and tinning operations must be performed with the exhaust ventilation turned on.

7. Dismantle radio equipment and unsolder wires from contact lugs and electrical connections in protective glasses.

8. Soldering work in blocks, racks, cabinets and other products can be performed when the voltage is completely removed from them.

9. Do not allow moisture to enter the tinning bath; dry all parts well before tinning.

10. In the premises where soldering is performed with solder containing lead, do not allow food, water, storage of personal belongings in order to avoid the ingress of lead into the human body. Store personal clothing in designated places, remove overalls before visiting the cafeteria, buffer, or first-aid post. Wash hands with soap and water before eating and after work.

11. Those who work with epoxy resins, compounds and their hardeners must have special clothing, rubber gloves and safety glasses. If resin, hardener or compound splashes on the skin, wash immediately with warm water and soap.

12. Since gasoline, acetone and other flammable liquids are used during the installation of electronic equipment, fire safety measures must be observed in all production areas:

a) it is forbidden to smoke and use open fire at the workplace,

b) all production operations must be carried out with a small amount of flammable and explosive liquids and in a technological container;

c) the technological container must be metal with threaded plugs and have a shape that excludes its overturning;

r) the container must bear a warning sign “Flammable”.

13. Used flushing fluids should be collected in special containers and should not be discharged into sinks and general sewers.
