TASK 70-03-00-200-502 Health And Safety Guide For Acid And Caustic Solutions

General

This safety precaution which is specified for CPS is to be used as an aid to the operator who works with these solutions.

This safety precaution is not to be used by a person for new bath make-up or for additions to the solutions. These persons must get special instructions from the local safety officer when they work with the different poisonous substances.

The medical doctor, safety engineer or the applicable person must give the necessary safety precautions and the first aid facilities, related with the use of chemicals in engine overhaul and cleaning.

WARNING

IT IS THE RESPONSIBILITY OF THE OPERATOR TO OBTAIN AND OBSERVE THE MANUFACTURERS MATERIAL SAFETY DATA SHEETS FOR CONSUMABLE MATERIALS INFORMATION SUCH AS, HAZARDOUS INGREDIENTS, PHYSICAL/CHEMICAL CHARACTERISTICS, FIRE, EXPLOSION, REACTIVITY, HEALTH HAZARD DATA, PRECAUTIONS FOR SAFE HANDLING, USE AND CONTROL MEASURES AND ALSO TO TAKE LOCAL REGULATIONS INTO CONSIDERATION.

Procedure

1. 1. Do not let the solution touch the skin or the eyes. Mild alkaline solutions such as detergent and metasilicate/phosphate based cleaning solution can cause irritation to the skin and eyes.
  2. If the solution accidently touches the skin, wash the skin with clean water.
  3. If the solution accidently touches the eyes, wash the eyes with clean water and get medical aid immediately.
2. 1. Do not let the solution touch the skin or the eyes. Hot and concentrated caustic solutions cause bad burns to the skin and eyes.
  2. Do not breathe the gases, this can cause burns to the breathing passages.
  3. Immediate medical aid is necessary if the solution touches the skin or eyes.
3. 1. Sodium or potassium cyanide solutions are very dangerous.
  2. Do not let the solutions touch the skin or the eyes. Poisoning can occur if the solutions are soaked in to the skin.
  3. Do not breathe the gases.
  4. Hydrogen cyanide gas can be made if the solution is mixed with an acid. This gas is highly dangerous.
  5. Solutions are stronger in alkaline and usually contain added caustic soda (refer to caustic solutions).
  6. The instructions given by the safety officer must be obeyed. Immediate medical aid is most important if the solution touches the skin or if poisoning occurs.
4. 1. Do not let the solution touch the skin or the eyes.
  2. Do not breathe the gases.
  3. Permanganate solutions are strong oxidising agents and cause burns to the skin and eyes. Suffocation can occur from breathing the gases.
  4. Strong alkaline solutions when they are hot can cause bad burns and etching to the skin (refer to caustic solutions).
  5. Immediate medical aid is most important if the solution touches the skin.
5. 1. Do not let the solution touch the skin or the eyes.
  2. Do not breathe the gases.
  3. Alkaline caustic chromate solutions when they are hot can cause an oxidising effect on the skin and eyes. It can also cause burns to the skin and eyes (refer to caustic solutions).
  4. Chromatic solutions are dangerous.
  5. Immediate medical aid is most important if the solution touches the skin or eyes and if poisoning occurs.
6. 1. Do not let the solution touch the skin or the eyes.
  2. Use full protective clothing, full face mask and suitable protective gloves when you work with the molten salt bath.
  3. Do not let water or wet parts get into the salt bath. The bath temperature (ca. 500 deg C) can cause explosive gases of water and spatter of contents.
  4. Heat and caustic burns can occur if the salts touch the skin (refer to caustic solutions). Immediate medical aid is most important.
7. 1. Do not let the solution touch the skin or the eyes.
  2. Do not breathe the gases.
  3. Hydrochloric acid solutions when they are hot can cause bad burns and stings to the skin.
  4. The gases cause painful burning to the breathing passages and to the eyes.
  5. Immediate medical aid is most important if the solution touches the body or is breathed in.
8. 1. Precautions are the same as for hydrochloric acid solution.
9. 1. Precautions are the same as for hydrochloric acid solution.
10. 1. Do not let the solution touch the skin or the eyes.
  2. Do not breathe the gases.
  3. Water must not be added to concentrated sulfuric acid. This causes the concentrated acid to heat up which will result in boiling and spattering of the solution. For dilute acid the concentrated acid must be added slowly, while you stir and cool to an unwanted quantity of water.
  4. Concentrated sulfuric acid when hot can cause oxidation, etching and dehydration of the skin. The hot acid gives off gases which cause etching of the breathing passages and eyes.
  5. Immediate medical aid is most important if the solution touches parts of the body.
11. 1. Do not let the solution touch the skin or the eyes.
  2. Do not breathe the gases.
  3. Nitric acid solution causes bad etching of the skin and eyes. Solution of a higher concentration when hot has a strong oxidising effect on the skin.
  4. If the solution starts to oxidize, brown gases are given off. These gases are poisonous and must not be breathed in.
  5. Immediate medical aid is most important if the solution touches the skin or if poisoning occurs.
12. 1. Do not let the solution touch the skin or the eyes.
  2. Do not breathe the gases.
  3. Diluted hydrofluoric acid solutions are strong acids which will cause a painful burn on the skin and eyes. Hydrofluoric acid is frequently used in mixtures with other acids such as nitric. This will give a better etching effect.
  4. Concentrated solutions give off HF gases which are dangerous and cause a very bad burn to the eyes and breathing passages. Use full protective clothing, face shield and breathing apparatus when you work with hydrofluoric acids.
  5. HF on hot surfaces can cause an explosive mixture of hydrogen and air.
  6. Immediate medical aid is most important if there is a leakage of the solution, poisoning or if the solution touches the skin. The medical people must wear breathing apparatus.
13. 1. Do not let the solution touch the skin or the eyes.
  2. Do not breathe the gases.
  3. Chromic acid solutions when hot cause very strong burns and oxidising properties on the skin and on organic materials such as cloths or plastics.
  4. Chromic acid solutions are very dangerous.
  5. Immediate medical aid is most important if the solution touches the skin or if poisoning occurs.
14. 1. This solution is used for the removal of metal platings and spray coatings.
  2. Do not let the solution touch the skin or the eyes.
  3. Do not breathe the gases.
  4. Obey safety precautions as for cyanide solutions.
  5. The nitroaromatics contained in this solution have oxidising properties. This can cause bad burns of the skin and on other materials such as paper, clothing and plastic.
  6. Immediate medical aid is most important if the solution touches the skin or eyes.
15. 1. Do not let the solution touch the skin or the eyes. Phenols can soak through the skin and cause poisoning.
  2. Do not breathe the gases. Breathing apparatus must be used.
  3. The liquid solutions and gases which contain phenols are very dangerous. They cause a burn of the skin, eyes and breathing passages.
  4. Immediate medical aid is most important if the solution touches the skin or eyes.
16. 1. Do not let the solution touch the skin or the eyes.
  2. Do not breathe the gases.
  3. Do not smoke near a trichloroethylene/perchloroethylene area. Trichloroethylene/perchloroethylene do not cause a fire risk. The heat from a cigarette or fire is sufficient to divide these materials in to the make up of hydrogen chloride gas (burn of the lungs) and the very poisonous phosgene (COCI2 - mustard gas).
  4. Immediate medical aid is most important if poisoning ocurrs.
17. 1. Safety precautions as for hydrochloric acid.
