Safe Operation

1. General requirements for labor protection

Work on galvanic baths should be started only after passing the briefing at the workplace and mastering the safe methods and techniques for its implementation. All workers in the electroplating shop must observe the following safety rules:

• perform only assigned work;
• work on serviceable equipment, using serviceable tools and devices;
• use the tool only for its intended purpose;
• about all malfunctions and the danger to others that arose during operation (lack of fences, uninsulated electrical wires and current-carrying parts of equipment, tools, etc.) immediately inform the master;
• do not lift weights in excess of the permissible norm (20 kg for women and 50 kg for men);
• in case of illness or even a minor injury, stop work, inform the master and contact the first-aid post;
• do not store personal belongings in the working room, do not eat and drink, do not smoke.

2. Labor protection requirements before starting work:

• put on work clothes (gown, apron, sleeves, rubber boots and gloves, goggles) depending on the nature of the work performed;
• carefully inspect the workplace and put it in order: remove all unnecessary items; arrange the tools, fixtures, materials and parts necessary for work in a convenient and safe manner, adhering to the principle: what is taken with the left hand should be on the left, and what with the right should be on the right; prepare personal protective equipment and check their serviceability;
• check that the floor near the workplace is clean, dry, not cluttered, and that the movable grate is in good working order;
• turn on ventilation.

3. Labor protection requirements during work:

• keep the workplace clean and tidy;
• promptly clean it from spilled electrolyte and other contaminants;
• do not clutter up aisles and driveways, carefully fold materials and products so that they do not fall apart;
• monitor the serviceability of the equipment, prevent leakage of electrolytes;
• fill the baths with electrolytes only when the supply and exhaust ventilation is turned on under the supervision of the master;
• when preparing an electrolyte, add acid to cold water and in no case vice versa, as this can lead to the release of acid from the vessel; pour the acid into the water in a thin stream, stirring the solution thoroughly all the time (it is not allowed to add acid to heated water);
• when preparing mixtures of acids, the latter should be poured with sulfuric acid;
• spilled acids and alkalis should be immediately neutralized and cleaned up: concentrated acids are abundantly diluted with water, covered with chalk until completely neutralized, then the resulting salt is swept away and removed;
• it is allowed to carry bottles with acids only in exceptional cases and over short distances, while the bottles are carried by two people on a special stretcher; it is prohibited to carry a bottle with acid on the back, shoulders or pressed to the chest;
• acidic electrolyte splashes on open parts of the body should be washed off with a plentiful stream of water, and then with a 2% solution of soda and again with water, splashes of chromium electrolyte with a 5% solution of hyposulfate, and electrolyte for oxidation with water; in all cases, if acid or alkali gets on the body, it is necessary to immediately treat the affected area with water (within 10 minutes); fountains installed at workplaces should be used for washing eyes;
• it must be remembered that any preliminary wiping of areas of the skin doused with acid or alkali only aggravates the burn;
• in order to avoid parts falling into the electrolyte bath, inspection, cleaning and fixing them in the device above the bath surface is prohibited;
• when removing parts from the bath, it is necessary to make an exposure for the electrolyte to drain into the bath;
• rods, suspensions and anodes should be cleaned only with a wet method, since non-ferrous metal dust is poisonous and inhaling it can cause poisoning;
• to remove parts from the bath, you should use special devices or tools - magnets, tongs, scoops;
• acids and alkalis stored in bottles, cans, canisters or barrels in warehouses, workshops or factory sites must have tags or labels with a clear indication of the name of the product; if the inscription is erased or the tags and labels are missing, then they need to be restored, for this, samples are taken and the products are analyzed in chemical laboratories; accidental damage to the skin of the hands must be immediately protected with a waterproof bandage or contact a first-aid post;
• protective clothing contaminated with acids, alkalis and other chemicals should be immediately removed and washed.
