This slideshare purpose to alert companies to the needs and care of equipment that should be inactive for long periods. Not only equipment, but also products in process, in WIP, and the facilities deserve a strict attention, so that the return to activities is without hitting and unnecessary expenses.

AUTHOR'S CURRICULUM SUMMARY
Revised and Updated in June 2020

2. 2
SERIOUS PROBLEMS MAY OCCUR IN STOPED FACTORIES, FACE
TO COVID 19 - LEARN HOW TO AVOID THEM.
✓THE PURPOSE OF THIS SLIDESHARE IS TO ALERT
THE BUSINESS PEOPLE, DIRECTORS AND OTHER
MANAGERS, OF THE CARE IN THE ACTIVITIES OF
STOP MACHINERY AND FACTORIES, FACE THE
COVID19.
✓A LOT OF CARE MUST BE TAKEN TO AVOID
PROBLEMS IN RETURN TO OPERATIONS, AFTER A
PERIOD OF WEEKS OR MONTHS, THAT WE ARE
STILL UNKNOWN FOR.

3. 3
➢ MACHINES THAT WORK CONTINUOUSLY SHUT DOWN AND STOP OPERATING;
➢ MANY PRODUCTS STAY IN PROCESS, AT THE PLACE WHERE PRODUCTION STOPPED;
➢ THERMAL ENVIRONMENTAL CONTROL EQUIPMENT IS TURNED OFF;
➢ AIR CIRCULATION EXHAUST AND FAN ARE DELIGATED;
➢ TPM ACTIVITIES - TOTAL PRODUCTIVE MAITENANCE - ARE PARALIZED;
➢ FACTORY "DOMESTIC" CLEANING IS STOPPED OR REDUCED;
➢ THE SUPERVISION OF THE CONDITIONS OF MACHINES AND EQUIPMENT BY OPERATORS AND SUPERVISORS IS
STOPPED OR HARMED;
➢ UNDESIRABLE EVENTS, BUT POSSIBLE AS BREAKING OF TILES, GUTTERS, SEALS, DOORS, PASS UNTIL NOTICE;
➢ OTHERS.
COMMON CONSEQUENCES RESULTING IN MOST IF LINE STOP:

4. 4
➢ PROTECT ALL MACHINES AND EQUIPMENT WITH TEMPORARY PROTECTIVE OILS. THESE OILS ARE GENERALLY
CONSTITUTED OF A "WAXY", HEAVY PART AND A DISPERSANATE OR DILUENT, "LIGHT" PART TO ALLOW THE
APPLICATION BY SPRAYING OR WITH BRUSHES AND BRUSHES.
➢ ONCE APPLIED TO THE "LIGHT" PORTION EVAPORATES LEAVING THE PROTECTIVE FILM, WHICH FUNCTION IS TO
PREVENT CONTACT OF WATER WITH METALS. AS THE NAME SAYS, THIS IS TEMPORARY PROTECTION, THAT IS, IF THE
STOP TIME IS TOO LONG, A RE-APPLICATION OF THE PRODUCT IS NECESSARY. THERE ARE MANY GOOD PRODUCTS AND
COMPANIES SHOULD ASK ORIENTATION TO THEIR SUPPLIERS, BUT IF NECESSARY, WE CAN INDICATE SOME, JUST
CONSULT US BY ONE OF THE MEANS DESCRIBED IN THE FINAL SLIDE.
➢ MACHINES THAT WORK WITH CUTTING OILS (MACHINING AND HYDRAULIC PRESSES) deserve special care, AS THESE
OILS ARE DEVELOPED TO ALLOW PRODUCTION, BUT THEY ARE NOT GOOD PROTECTIVE FOR CORROSION, MAINLY
USED IN PRESSES. THE OBJECTIVE IS TO SUPPORT HIGH TENSIONS AT THE TIME OF CUTTING, BENDING, ETC AND ARE
AGGRESSIVE AS TO CORROSION. THE SOLUTION IN THESE CASES PASSES BY CLEANING AND REMOVING THESE OILS
AND APPLYING THE PROTECTIVES, AS DESCRIBED ABOVE.
USEFUL AND NECESSARY PREVENTIVE MEASURES THAT CAN AND SHOULD BE TAKEN:

5. 5
➢ DYNAMIC MACHINES WITH GEARS DESERVE SPECIAL ATTENTION. THE GEARS ARE NORMALLY LUBRICATED
CONTINUOUSLY OR RECEIVED A GREASE FOR LUBRICATION, DURING THEIR OPERATION.
➢LONG STOPS DRY OILS AND OILS DROUGHT AND NOT ALL PARTS ARE PROTECTED WHICH RESULTS IN
ENFORCEMENTS AND BREAKS ON RETURN TO WORK WHICH RESULTS IN COSTS AND LINE STOP TIME. THE
SOLUTION IN THESE CASES IS SIMILAR TO THE PRESENTED IN THE ABOVE ITEM.
➢WATER TANKS AND RESERVOIRS, MORE OR LESS CONTAMINATED, IF POSSIBLE MUST BE EMPTYED AND
PROTECTED WITH THE SAME TEMPORARY PROTECTIVE OIL, WITH A LIGHT LAYER THAT MUST THEN BE
REMOVED FOR TANK USE. IF THE TANKS ARE OF LARGE VOLUMES, THE DECISION MUST BE TAKEN IN
ACCORDANCE WITH THE CHARACTERISTICS OF THE CORROSIVITY OF THE WATER, WHICH IS EASY TO BE
DONE AND IF THE RESULT IS OF LOW AGGRESSIVITY, NO ACTION NEEDS TO BE TAKEN, IF ANY ADDITION TO
ADDITION CORROSION INHIBITOR EASILY SOLVES THE PROBLEM AND IS LOW COST.
MUSEFUL AND NECESSARY PREVENTIVE MEASURES THAT CAN AND SHOULD BE TAKEN:

6. 6
➢ MY COLLEAGUES, MANAGERS AND FACTORY ENGINEER: IT LOOKS LIKE A LOT OF WORK. IN FACT THERE ARE
MANY ACTIVITIES, BUT WITH A SMALL MAINTENANCE HAND, WHO NORMALLY ALREADY KNOWS THE MAJORITY
OF THE PROCEDURES, WITH AN ADEQUATE COORDINATION THIS CAN BE DONE.
➢THESE TASKS CAN BE IMPLEMENTED. I CAN AFFIRM, BY OWN EXPERIENCE AND PRACTICE THAT THESE
ACTIVITIES ARE NECESSARY, MAINLY IF THE STOPS LAST MORE THAN WEEKS. ON THE OTHER SIDE THE
ALTERNATIVES ARE EASY TO PERFORM, LOW COST, IF COMPARED WITH THE CONSEQUENCES OF NOT DOING IT, AS
DESCRIBED IN THE PREVIOUS ITEMS.
➢WE ARE ALSO ABLE TO DO ALL THE INVESTIGATION SERVICE OF THE BEST ALTERNATIVE FOR EACH MACHINE
AND SECTOR, PRODUCTS ON WIP. IN STOCK OF FINISHED PRODUCTS AND RAW MATERIAL, BECAUSE WE HAVE
EXPERIENCED IT IN MANY STOPS, IN SEVERAL COMPANIES DURING COLLECTIVE HOLIDAYS, FOR EXAMPLE. THIS
METHOD THAT IS VERY KNOWN AND USED, PRIMARYLY IN THE TRANSPORT OF PRODUCTS.
➢ THE FREQUENCY AND QUANTITY OF OILING DEPENDS ON THE LOCATION OF THE COMPANY INVOLVING:
CLIMATE (QUANTITY OF RAIN, RELATIVE HUMIDITY, TEMPERATURE VARIATIONS, ETC), PRESENCE OF SUGITIES -
DUST FROM WORKS NEAR AIR POLLUTION, IN OTHER.
MUSEFUL AND NECESSARY PREVENTIVE MEASURES THAT CAN AND SHOULD BE TAKEN:

7. 7
➢ HOW CAN YOU CHECK IN OUR PROFILE WE HAVE A LOT OF EXPERIENCE IN THIS CORROSION AREA WHICH IS
THE FOCUS OF THE COMPANY AND OUR PROFESSIONALS HAVE PRACTICAL TECHNICAL KNOWLEDGE, FOR
WORKING IN COMPANIES ON "FACTORY FLOOR" AND NOT ONLY ACADEMIC. OUR WORK CAN BE SINCE THE
EXECUTIVE PROJECT OF HOW TO DO IT, THE INDICATIONS OF THE INPUTS AND THE "IN LOCO" FOLLOW-UP FOR
GUIDANCE AND CHECKING.
➢ WE GIVE FULL WARRANTY THAT THERE WILL BE NO CORROSION IF OUR RECOMMENDATIONS ARE FOLLOWED
AND WE WILL FOLLOW THE SITUATION FREQUENTLY, DEPENDING ON THE DURATION OF THE STOP. THIS WILL BE
THE SUBJECT MATTER, CASE BY CASE.
➢ WE REMEMBER THAT IT IS ALWAYS VERY NASTY AND HARMFUL FOR COMPANIES TO RETURN TO ACTIVITIES
AND EQUIPMENT NEED REPAIR, CLEANING, LUBRICATION WHICH CAUSES DELAY IN PRODUCTION AND
ADDITIONAL COSTS WITH EQUIPMENT BREAKDOWN WHICH ARE NOT MENTIONED.
MUSEFUL AND NECESSARY PREVENTIVE MEASURES THAT CAN AND SHOULD BE TAKEN:

SOME EXAMPLES OF WHAT CORROSION CAUSES IN STANDING MACHINES WITHOUT
PROPER PROTECTION
THE PICTURES 1 TO 3 ARE A VEHICLE THAT WAS STANDING WITHOUT PROTECTION FOR 30 DAYS

REPAIRENERALIZED AND INTENSE CORROSION
WITHOUT REPAIR.

➢ BE PRUDENT, PAY ATTENTION TO THESE ARGUMENTS, ACT WITH PREVENTION AND THE APPROPRIATE
TECHNOLOGY AND, THEREFORE, THE COMPANY WHERE YOU ACT WILL BE REWARDED AND YOU ALSO!
➢ THE PICTURES PRESENTED ARE EXAMPLES OF WHAT CAN AND OCCURS IN MACHINERY AND EQUIPMENT
STOPPED AND WITHOUT PROTECTIONS. THIS IS MY PHOTOS OF A VEHICLE IN USE, BUT ITS OWNER HAS NO
KNOWLEDGE THAT CORROSION COULD BE SO FAST. THEY ARE PHOTOS OF INTENSE CORROSION, BUT THE
PURPOSE WAS FACT TO SHOW THE SERIOUS CONSEQUENCES THAT LACK OF PROTECTION MAY RESULT.
➢ DESPITE WANTING TO HELP, IT IS CLEAR THAT THERE WAS NOT A LOT OF POSSIBLE CORRECTION IN THIS
CASE, BUT I MADE SOME RECOMMENDATIONS FOR POSSIBLE REPAIRS AND THE PRESENT CARE FOR
CORROSION DOES NOT INCREASE, AND FUTURE TO AVOID THAT PROBLEMS AGAIN.
➢ NEXT WE PRESENT SOME BASIC CONCEPTS THAT EXPLAIN WHY THIS PHENOMENON OCCURS NATURALLY,
WITH SOME DETAILS AND CHARACTERISTICS OF ITS ATTACKS.
USEFUL AND NECESSARY PREVENTIVE MEASURES THAT CAN AND SHOULD BE TAKEN:

12. 12
➢CORROSION: Destruction of a
material, usually metallic, through
chemical or electrochemical
interaction of the environment.
CORROSION DEFINITION:

13. 13

3
➢CORROSION IS A NATURAL
PHENOMENON AND SO THEIR
CONSEQUENCES SOMETIMES IN
FAVOR IN OTHER HARM.
• IMPORTANT CONSIDERATIONS:

14. 14
• THUS, MOST OF THE PROBLEMS
ATTACHED TO CORROSION ARE IN
REALITY RESULT OF OUR
IGNORANCE AND LACK OF
UNDERSTANDING OF THE
PHENOMENON AND ITS
MECHANISMS.
• IMPORTANT CONSIDERATIONS:

15. 15
➢ THE BIG EFFECT OF THE 5Ss PROCESS ON CORROSION IS THAT THE
MANUFACTURING ENVIRONMENT IS ALWAYS CLEANER ARISING
FROM THE ACTIONS DESCRIBED IN THE PREVIOUS SLIDES.
METALLIC POWDER OR FROM OTHER MATERIALS, LIKE SILICA CLAY,
DUST IS EXTREMELY CORROSION ACCELERATORS.
➢ ATHE PARTICLES ACCELERATE THE CONDENSATION OF WATER AND
OTHER LIQUIDS BY CAPILLARITY AND ALLIED TO AN EFFECT CALLED
OXYGEN DIFFERENTIATION, CORROSION INSTALLS UNDER THESE
PARTICLES AND ARE, INITIALLY, INVISIBLE, BETWEEN, FEELING AND
FEASING.
➢ THIS IS THE REASON FOR COMPANIES THAT KNOW THIS FACT AND
HAVE THIS CONCEPT, ARE EVERY DAY LOOKING FOR A CLEANER
ENVIRONMENT AND FREE OF SUSPENDED PARTICLES.
• IMPORTANT CONSIDERATIONS:

16. 16

• CONCLUSIONS:
• CORROSION IS A NATURAL PHENOMENON
AND, THEREFORE, IT CANNOT BE CONSIDERED
BENEFICIAL OR MALPHIC.
• NOBODY SHOULD WORRY ABOUT
COMBATING CORROSION, BUT IN SEARCHING
TO UNDERSTAND THE PHENOMENON BETTER
TO FIND THE BEST SOLUTION.
• BETTER UNDERSTANDING CORROSION AND
ITS MECHANISMS IS THE STARTING POINT FOR
LIVING WITH IT, TAKING ADVANTAGE OF ITS
MANY BENEFITS AND TECHNICALLY AVOIDING
ITS DAMAGES.

17. 17
• RESULTS OF UNWANTED CORROSION:
➢ BE PROACTIVE, YOU HAVE NO ONE TO WAIT
FOR CIRCUMSTANCES OR OTHER PEOPLE TO
CREATE PERPECTIVE BY EXPANDING
EXPERIENCES.
➢ YOU CAN CONSCIOUSLY CREATE AND
PERFORM THE NECESSARY YOURSELF.
➢ AND THAT IS WHICH MAKES PEOPLE
DIFFERENT FROM EACH OTHER, AND MAKES A
BIG PRACTICAL DIFFERENCE.
